Description

Conveyor device and battery production line

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on November 27, 2023, with application number 202311598053.3 and application name “Conveying Device and Battery Production Line”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of battery technology, and more specifically, to a conveying device and a battery production line. Background Art

[0003] The battery production process involves multiple production steps, each implemented through different production equipment. In many cases, a conveyor system is required to transfer battery cells. During this transfer, the cells are typically placed in a tray, which provides some protection during transportation.

[0004] When using flexible chains to transport cups, multiple cups are arranged in sequence on the flexible chains and moved forward by the flexible chains. At the diverging and converging locations of the multiple flexible chains, the movement of the cups on different flexible chains needs to be controlled to prevent interference between the cups on different flexible chains. Generally, a stop mechanism is provided on the flexible chains to control the movement and stopping of the cups on different flexible chains. Since the flexible chains are always in motion and the cups are blocked by the stop mechanism, when there are a large number of cups on the flexible chains, the instantaneous impact load of the cups on the stop mechanism is too large, which can easily damage the stop mechanism.

[0005] Summary of the Invention

[0006] The purpose of the embodiments of the present application is to provide a conveying device, aiming to solve the technical problem in the prior art that the stopping mechanism is easily damaged due to excessive instantaneous impact load.

[0007] To achieve the above objectives, the technical solution adopted in this application is:

[0008] In a first aspect, a conveying device is provided, comprising:

[0009] A conveying mechanism having a conveying area, the conveying mechanism being used to convey the material in the conveying area along a conveying direction;

[0010] A blocking mechanism, used to extend into the conveying area to stop the movement of materials along the conveying direction;

[0011] The damping mechanism is at least partially located in the conveying area. In the conveying direction, the damping mechanism and the blocking mechanism are spaced apart. The damping mechanism can move relative to the conveying mechanism driven by the material and is used to provide resistance for the material.

[0012] The conveying device provided in the embodiment of the present application can be used in a battery production line. The conveying device is used to convey the cup, that is, the material transported in the conveying device is the cup, and the conveying mechanism is used to convey the material in the conveying area along the transmission direction. The blocking mechanism can extend into the transmission area to block the cup. Since a damping mechanism is provided in the conveying device, the damping mechanism is used to provide resistance for the cup. Therefore, when the cup moves along the transmission direction and in the direction close to the blocking mechanism, the damping mechanism provides resistance for the cup when the cup passes through the damping mechanism, thereby reducing the impact force of the cup on the previous cup, and further reducing the impact force of the cup on the blocking mechanism, slowing down the damage to the blocking mechanism to a certain extent, and improving the service life of the blocking mechanism.

[0013] In a possible design, the damping mechanism includes a damping portion and a damping driver, wherein the damping driver is used to drive the damping portion to move closer to or farther away from the transfer area.

[0014] In this arrangement, the damping part can be moved to a position away from the conveying area by the damping driver, so that whether to provide resistance to the cup can be adjusted according to the specific conveying requirements of the cup.

[0015] In one possible design, the conveying device also includes a first sensor. In the transmission direction, the first sensor is located on the rear side of the damping part, and the first sensor is spaced apart from the damping part. The first sensor is used to detect whether there is material in the conveying area opposite to the first sensor; when the first sensor detects that there is no material in the conveying area opposite to the first sensor, the damping drive drives the damping part to move away from the conveying area.

[0016] In this setting, when the first sensor detects that there are no supporting cups in the corresponding conveying area, the damping driver drives the damping part away from the conveying area. That is to say, when the number of supporting cups in front of the damping part is relatively small, the damping part can be automatically moved to a position away from the conveying area by the damping driver to reduce the resistance provided to the supporting cups and facilitate the transportation of the supporting cups.

[0017] In one possible design, the damping mechanism also includes a connecting seat, which includes a first plate and a second plate, the first plate is connected to the second plate at an angle, the first plate is connected to the damping driver, the damping part is movably mounted on the second plate, and the damping driver is located in the space enclosed by the first plate and the second plate.

[0018] In this arrangement, since the damping driver is installed in the space enclosed by the first plate and the second plate, the overall structure of the damping mechanism is more compact and occupies less space.

[0019] In one possible design, the damping mechanism also includes a damping mounting seat, the damping mounting seat is connected to the transmission mechanism, the damping driver is connected to the damping mounting seat, one of the damping mounting seat and the second plate is provided with a first slide rail, and the other is provided with a first slider, and the first slider is slidably mounted on the first slide rail.

[0020] In this arrangement, the second plate drives the damping part to move more stably relative to the damping mounting seat.

[0021] In a possible design, there are multiple damping mechanisms, and the damping parts of the multiple damping mechanisms are arranged at intervals in the transmission direction.

[0022] In this arrangement, since there are multiple damping mechanisms, multiple resistances can be provided to the support cup in different areas through the multiple damping mechanisms, thereby further reducing the instantaneous impact force of the support cup on the barrier mechanism.

[0023] In one possible design, the damping mechanism also includes a base, a pressure piece, an angular contact bearing group and a rod. The outer ring of the angular contact bearing group is connected to the base, the inner ring of the angular contact bearing group is connected to the rod, the pressure piece is located on one side of the axial direction of the angular contact bearing group, the pressure piece provides pressure for the angular contact bearing group, the damping part is connected to the rod by transmission, the damping part can drive the rod to rotate, and the material can push the damping part to rotate.

[0024] In this setting, when the material passes through the damping part, the material needs to drive the damping part to rotate before it can continue to move along the transmission direction. The damping part is connected to the rod part, and the rod part is connected to the angular contact bearing group. Under the pressure of the pressure piece, the angular contact bearing group needs to overcome the pressure during the rotation process, thereby achieving the effect of providing resistance to the material.

[0025] In a possible design, the pressure member includes an elastic member, and the damping mechanism further includes an adjusting member. The elastic member is located between the adjusting member and the angular contact bearing assembly, and the adjusting member can move relative to the rod to change the compression amount of the elastic member.

[0026] In this setting process, the setting of the elastic member can maintain the pressure on the angular contact bearing group for a long time.

[0027] In one possible design, the damping part is provided with a through hole, the rod passes through the through hole, the angular contact bearing group and the adjusting part are respectively located on both sides of the damping part, and the damping mechanism also includes a connecting part, which is fixedly connected to the damping part and is transmission-connected to the rod, and the connecting part can drive the rod to rotate.

[0028] In this arrangement, the rod portion is passed through the damping portion to facilitate driving the damping portion to rotate.

[0029] In a possible design, two ends of the connecting member are in contact with the elastic member and the angular contact bearing set respectively.

[0030] In this arrangement, the elastic member applies pressure to the angular contact bearing group through the connecting member. Compared with the elastic member, the connecting member can increase the contact area with the angular contact bearing group, which is more conducive to applying compressive stress to the angular contact bearing group.

[0031] In one possible design, the damping mechanism also includes a scale structure with scale lines provided on it. One end of the scale structure contacts the adjusting member, and the other end extends into the through hole. The scale structure can move relative to the rod under the drive of the adjusting member.

[0032] In this setting, the relative position of the adjusting member on the rod can be directly observed through the scale lines of the scale structure, which is helpful for judging the magnitude of the compressive stress applied to the angular contact bearing group, and thus is helpful for judging the magnitude of the resistance provided by the damping mechanism to the support cup.

[0033] In one possible design, the elastic member is a spring, which is sleeved on the rod, part of the spring is located in the through hole, the scale structure has a accommodating cavity, part of the spring is located in the accommodating cavity, and the scale structure contacts the end of the spring away from the angular contact bearing group.

[0034] In this arrangement, the scale structure plays a certain protective role for the spring, and the relative positions of the scale structure, the spring and the damping part are more compact, which facilitates reducing the space occupied by the damping mechanism.

[0035] In a possible design, the rod has an external thread, the adjusting member has a threaded hole matching the external thread, and the adjusting member is threadedly connected to the rod through the threaded hole.

[0036] In this setting process, the compressive stress applied to the angular contact bearing group can be adjusted by screwing the adjusting piece, and the adjustment process is convenient.

[0037] In one possible design, the conveying device also includes a counting sensor, which includes a detection end. A trigger structure is provided on the damping part. The damping part moves under the drive of the material to drive the trigger structure to trigger the detection end. The counting sensor can record the number of times the detection end is triggered.

[0038] In this setting process, the setting of the counting sensor can be used to detect the number of cups passing through the damping part, which is convenient for calculating the number of cups passing through the production line and facilitating the delivery of a set number of cups.

[0039] In a possible design, a liquid injection hole is provided on the second plate, and the liquid injection hole is arranged opposite to the first sliding block.

[0040] In this arrangement, lubricant can be added between the first slider and the first slide rail through the injection hole to improve the smoothness of the first slider when moving relative to the first slide rail.

[0041] In one possible design, the barrier mechanism includes a barrier member and a barrier driver, the barrier driver is used to drive the barrier member to move to extend into the conveying area, the barrier member includes a limiting end, and in the transmission direction, the limiting end has a first surface and a second surface, the first surface and the second surface are arranged to be relatively inclined, and the distance between the first surface and the second surface gradually increases in the direction away from the conveying area.

[0042] In this arrangement, the size of the barrier member on the side close to the transfer area is relatively small, and it is easy to extend into between two adjacent support cups.

[0043] In a possible design, in the transport direction, the first surface is located behind the second surface, and the first surface is perpendicular to the transport direction.

[0044] In this arrangement, the contact area between the first surface and the support cup is relatively larger, which facilitates the isolation operation of the support cup.

[0045] In a possible design, a buffer structure is installed on the first surface.

[0046] In this arrangement, the buffer structure can reduce the impact force between the support cup and the first surface.

[0047] In a possible design, the first surface is provided with an embedding groove, the buffer structure is cylindrical, the buffer structure is installed in the embedding groove, and part of the buffer structure is located outside the embedding groove.

[0048] In this arrangement, the cylindrical buffer structure partially protrudes outside the embedding groove, so that the buffer structure contacts the support cup earlier than the first surface, thereby reducing the contact probability between the support cup and the first surface and reducing the impact of the support cup on the first surface.

[0049] In a possible design, there are multiple limiting ends, and the multiple limiting ends are spaced apart in a direction perpendicular to the transmission direction.

[0050] In this arrangement, the plurality of limiting ends can contact a plurality of different areas of a support cup, thereby improving the stability of the support cup barrier and preventing the support cup from tipping over.

[0051] In a possible design, the barrier mechanism further includes a barrier mounting seat, one of the barrier mounting seat and the barrier member is provided with a second slide rail, and the other is provided with a second slider, and the second slider is slidably mounted on the second slide rail.

[0052] In this arrangement, the barrier member has higher stability during movement relative to the barrier mounting seat.

[0053] In one possible design, the barrier mechanism also includes a third plate and a fourth plate, the third plate and the fourth plate are connected at a relative angle, the barrier driver is installed in the area enclosed by the third plate and the fourth plate, the barrier driver is transmission-connected to the third plate, and the limit end is connected to the fourth plate.

[0054] In this arrangement, since the barrier driver is installed in the space surrounded by the third plate and the fourth plate, the overall structure of the barrier mechanism is more compact and occupies less space.

[0055] In one possible design, the conveying device also includes a second sensor. In the transmission direction, the second sensor is located on the rear side of the barrier mechanism. The second sensor is spaced apart from the barrier mechanism. The second sensor is used to detect whether there is material in the conveying area opposite to the second sensor.

[0056] In this arrangement, since a second sensor is provided at the rear side of the barrier mechanism, it can detect whether material is being transferred therefrom at a distance from the barrier mechanism, so as to determine whether the material needs to be blocked or released.

[0057] In a possible design, the conveying mechanism includes a frame, the conveying area is located on the frame, and the blocking mechanism and the damping mechanism are respectively installed on the frame.

[0058] In this arrangement, the frame provides installation space for the blocking mechanism and the damping mechanism, making it easier to move the conveying device as a whole.

[0059] In a possible design, the blocking mechanism is installed on a side of the frame, and / or the damping mechanism is installed on a side of the frame.

[0060] In this arrangement, the installation positions of the blocking mechanism and the damping mechanism do not occupy the installation space of the transmission area.

[0061] In a possible design, the frame is provided with a first slot body, and the blocking mechanism is installed at the first slot body;

[0062] And / or, the frame is provided with a second slot body, and the damping mechanism is installed at the second slot body.

[0063] In this arrangement, the installation operation of the blocking mechanism and the damping mechanism is facilitated.

DETAILED DESCRIPTION

[0084] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0085] In the description of the embodiments of the present application, the term "plurality" refers to more than two (including two).

[0086] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0087] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the conveying device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0088] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0089] The battery production line is used for the production of batteries. The battery production line has multiple production devices or equipment to facilitate the realization of different process flows in the battery production process. In some cases, after the production device of the previous process flow completes the operation, the battery cells need to be transported to the production device corresponding to the next process flow. The cells can be transferred by a conveying device. During the cell transfer process, the cells are usually placed in a cup. Since the number of operations performed by the production device at one time is limited, the number of cups transferred to the production device at one time is limited. In the conveying device, the conveying chain plate is always moving, and the cups are blocked by a stop mechanism to wait for the next delivery. At the position of divergence and confluence of multiple conveying chain plates, the cups on different conveying chain plates also need to be blocked by a stop mechanism to avoid interference between the cups on different conveying chain plates.

[0090] However, since the conveying chain of the conveying device is in motion and the cups are blocked by the stopping mechanism, when there are a large number of cups on the conveying chain, on the one hand, the instantaneous impact load of the cups on the stopping mechanism is too large, and the stopping mechanism is easily damaged; on the other hand, the squeezing force between adjacent cups is large, and it is difficult to remove one or several cups for inspection.

[0091] Based on the above considerations, and in order to solve the above problems, a conveying device 10 is provided, which can be applied to a battery production line. As shown in Figure 1, the conveying device 10 includes a conveying mechanism 100, a blocking mechanism 200, and a damping mechanism 300. The conveying mechanism 100 is used to transport the cups, the blocking mechanism 200 is used to prevent the cups from moving, and the damping mechanism 300 is used to provide a certain resistance to the cups, so as to reduce the force of the cups on the cups in front of them, and the force of the cups on the blocking mechanism 200, thereby reducing the impact on the blocking mechanism 200 and the squeezing force between adjacent cups. While protecting the blocking mechanism 200, it is also convenient to remove one or more cups from the multiple blocked cups.

[0092] The conveying device provided in the embodiment of the present application is applicable to a product production line, and is used to realize the conveying of materials. The conveying device provided in the embodiment of the present application is particularly suitable for conveying methods in which materials need to be conveyed in batches, and the spacing between adjacent materials is relatively small or there is no spacing. Batch conveying means that after conveying a batch of multiple materials, the conveying of materials needs to be stopped for a certain period of time, and then the conveying of the next batch of multiple materials is continued. Exemplarily, the conveying device provided in the embodiment of the present application can be applicable to a battery production line, and is used to convey raw materials, semi-finished products or finished products in the battery production and manufacturing process. In a specific example, the conveying device provided in the embodiment of the present application is applicable to a battery production line, and is used to convey battery cells. During the conveying process of the battery cells, the battery cells are accommodated in a support cup. Therefore, the material located on the conveying mechanism is the support cup, and the battery cells can be accommodated in the support cup.

[0093] The conveying device provided in the embodiments of the present application is explained in detail below.

[0094] As shown in Figure 1, the conveying device 10 includes: a conveying mechanism 100, a blocking mechanism 200 and a damping mechanism 300. The conveying mechanism 100 has a conveying area 101, and the conveying mechanism 100 is used to convey the material 11 in the conveying area 101 along the transmission direction; the blocking mechanism 200 is used to extend into the conveying area 101 to stop the movement of the material 11 along the transmission direction; the damping mechanism 300 is at least partially located in the conveying area 101. In the transmission direction, the damping part 310 and the blocking mechanism 200 are spaced apart. The damping mechanism 300 can move relative to the conveying mechanism 100 under the drive of the material 11, and the damping mechanism 300 is used to provide resistance for the material 11.

[0095] The conveyor device 10 provided in the embodiment of the present application can be used in a battery production line. The conveyor device 10 is used to convey a cup. That is, the material 11 transported by the conveyor device 10 is a cup. The conveyor mechanism 100 is used to convey the material 11 in a conveying area 101 along a transmission direction. The conveyor mechanism 100 has a conveying area 101, which is an area on the conveyor mechanism 100 for moving the material 11. A transmission structure may be provided in the conveying mechanism 100, and the transmission structure may include flexible transmission chain plates, transmission chains, transmission rollers, transmission trays, transmission belts and other structures. At least part of the transmission structure is the conveying area 101. For example, the flexible transmission chain plate is a ring structure formed by multiple chain plates connected to each other, which at least includes an upper area and a lower area. The upper area is located above the lower area. The chain plates in the upper area move a distance along the transmission direction and then move downward to the lower area. The chain plates located in the lower area move a distance in the opposite direction of the transmission direction and then move upward to the upper area. In this way, the chain plates can circulate in the conveying mechanism 100. The chain plates in the upper area are used to drive the material 11 to move along the transmission direction. The area where the chain plates in the upper area are located is the conveying area 101.

[0096] The conveying direction is the direction in which material 11 moves within conveying zone 101. Material 11 moves forward, meaning that material 11 moves from back to front under the conveying mechanism 100. Suppose two materials 11 are arranged one behind the other within conveying zone 101. Each material 11 moves along the conveying direction to point X. The material 11 at the front arrives at point X first, while the material 11 at the back arrives at point X later. In other words, the material 11 that arrives at point X first is the material 11 at the front, and the material 11 that arrives at point X later is the material 11 at the back. Point X is any point within conveying zone 101.

[0097] The conveying direction may be a straight line or a curved line, or the conveying direction may be partially straight and partially curved. When the conveying direction is a straight line, the material 11 moving along the conveying direction is considered to be moving along a straight line; when the conveying direction is a curved line, the material 11 moving along the conveying direction is considered to be moving along a curved line; when the conveying direction is partially straight and partially curved, the material 11 moving along the conveying direction is considered to be moving straight line in some intervals and moving curved line in some intervals.

[0098] The blocking mechanism 200 is configured to extend into the conveying zone 101 to block the materials 11 therein. The blocking mechanism 200 can be movable or fixed relative to the conveying zone 101. The blocking mechanism 200 can be moved relative to the conveying zone 101 to extend into or out of the conveying zone 101. After extending into the conveying zone 101, the blocking mechanism 200 is fixed relative to the conveying zone 101 to block the materials 11. After moving out of the conveying zone 101, the blocking mechanism 200 is fixed relative to the conveying zone 101 to allow the materials 11 therein to continue to move forward along the conveying zone 101. For example, the blocking mechanism 200 can move in a direction away from or toward the conveying zone 101. When the blocking mechanism 200 moves toward the conveying zone 101, at least a portion of the blocking mechanism 200 moves into the conveying zone 101, thereby preventing the materials 11 from continuing to move forward along the conveying zone 101. When the blocking mechanism 200 moves a certain distance away from the conveying area 101 , it moves to the outside of the conveying area 101 , thereby having no blocking effect on the material 11 , and the material 11 can continue to move forward along the conveying area 101 .

[0099] Illustratively, the blocking mechanism 200 can move between a first position and a second position. As shown in FIG2 , the blocking mechanism 200 is in the first position, with at least a portion of the blocking mechanism 200 moved to the middle region of the conveying zone 101 in a direction perpendicular to the conveying direction. For ease of description, the direction perpendicular to the conveying direction is referred to as the width direction of the conveying zone 101. In FIG2 , the end of the blocking mechanism 200 is located at the midpoint of the width direction of the conveying zone 101. That is, in the width direction of the conveying zone 101, the blocking mechanism 200 blocks at least half of the region of the conveying zone 101 corresponding to the blocking mechanism 200. Of course, in other configurations, when the blocking mechanism 200 is in the first position, the blocking mechanism 200 can completely block the region of the conveying zone 101 corresponding to the blocking mechanism 200 in the width direction. Illustratively, the barrier mechanism 200 includes a barrier member 220 and a barrier driver 210. The barrier driver 210 is configured to drive the barrier member 220 toward or away from the conveying zone 101. When the barrier mechanism 200 is in the first position, the end of the barrier member 220 extends to the side of the conveying zone 101 away from the barrier driver 210. This means that the barrier member 220 completely blocks the area of ​​the conveying zone 101 corresponding to the barrier member 220 in the width direction. As shown in FIG3 , the barrier mechanism 200 is in the second position. The barrier mechanism 200 does not extend into the area of ​​the conveying zone 101 through which the material 11 passes. In FIG3 , the material 11 is a tray cup, the width of which is approximately equal to or similar to the width of the conveying zone 101. Therefore, the barrier mechanism 200 does not extend into the conveying zone 101 in the second position. If the width of the material 11 is smaller than the width of the conveying area 101 , then in the conveying device 10 transporting such material 11 , the blocking mechanism 200 may partially extend into the conveying area 101 when in the second position, but will not contact the material 11 transported by the conveying area 101 .

[0100] In the drawings of this embodiment, the direction indicated by arrow A is the conveying direction, the direction indicated by arrow B is the direction approaching the conveying area 101, and the direction indicated by arrow C is the direction away from the conveying area 101. The direction indicated by arrow A and the direction indicated by arrow B are angled relative to each other, the directions indicated by arrows A and B are not parallel, and the directions indicated by arrows B and C are opposite. For example, FIG1 is a top view of a battery production line, which includes two conveying devices 10. The conveying direction of one conveying device 10 is from left to right as shown in FIG1. ​​In this conveying device 10, the moving direction of the barrier 220 is perpendicular to the conveying direction.

[0101] The damping mechanism 300 is spaced apart from the barrier mechanism 200. This means that the material 11, after passing through the damping mechanism 300, must move a further distance before reaching the barrier mechanism 200. As the material 11 passes through the damping mechanism 300, it drives the damping mechanism 300 to move relative to the conveying mechanism 100. This means that the damping mechanism 300 does not completely prevent the movement of the material 11, and the material 11 will continue to move along the conveying direction to the barrier mechanism 200. However, because the damping mechanism 300 provides resistance to the material 11 as it drives the damping mechanism 300, the force exerted by the material 11 partially offsets the resistance of the damping mechanism 300, thereby reducing the impact force exerted by the material 11 on the barrier mechanism 200 as it continues to move backward. When a material 11 is blocked by the blocking mechanism 200, the materials 11 located at the rear side of the material 11 are in contact with the material 11 in front. Due to the setting of the damping mechanism 300, the force of the material 11 on the rear side pushing it forward is partially offset by the damping mechanism 300, thereby reducing the impact force of the material 11 on the front side on the material 11, that is, the extrusion force between adjacent materials 11 is reduced, which facilitates the removal of one or more of the multiple materials 11 in contact with each other.

[0102] In one example, one or more damping mechanisms 300 may be provided on the rear side of the barrier mechanism 200 , that is, the material 11 moving along the transmission direction in the conveying area 101 first passes through one or more damping mechanisms 300 before reaching the location of the barrier mechanism 200 .

[0103] In a possible design, there are multiple damping mechanisms 300, and the damping parts 310 of the multiple damping mechanisms 300 are arranged at intervals in the transmission direction. For example, there are two damping mechanisms 300 in FIG1 .

[0104] The number of damping mechanisms 300 increases, thereby increasing the resistance to the material 11. That is to say, assuming that two damping mechanisms 300 are arranged at intervals in the transmission direction, the forward force of the material 11 decreases a part when passing through the first damping mechanism 300, and then the forward force decreases a part again when passing through the second damping mechanism 300, thereby further reducing the impact force of the material 11 on the blocking mechanism 200.

[0105] When there are a large number of cups in the conveying area 101, after the blocking mechanism 200 blocks the cups, some cups have not yet moved to the damping mechanism 300 adjacent to the blocking mechanism 200 and come into contact with the cups in front. In order to reduce the force exerted by the cups located relatively further back on the cups in front, multiple damping mechanisms 300 are arranged at intervals in the conveying direction. That is, multiple damping mechanisms 300 can provide resistance to cups that are relatively farther from the blocking mechanism 200, and multiple damping mechanisms 300 can also provide multiple resistances to cups that are relatively closer to the blocking mechanism 200. "Relatively closer" and "relatively farther" from the blocking mechanism 200 refer to the relative distances between the cups and the blocking mechanism 200 when the blocking mechanism 200 blocks the cups in the conveying area 101. Among the multiple damping mechanisms 300, the cups in the conveying area 101 corresponding to the area between the damping mechanism 300 closest to the barrier mechanism 200 and the barrier mechanism 200 are the cups that are relatively closer to the barrier mechanism 200, and the other cups are relatively farther away from the barrier mechanism 200.

[0106] In this arrangement, since there are multiple damping mechanisms 300 , multiple damping mechanisms 300 can provide multiple resistances to the support cup in different areas along the transmission direction of the conveying area 101, further reducing the instantaneous impact force of the support cup on the blocking mechanism 200.

[0107] In one embodiment, the damping mechanism 300 is movable relative to the conveying zone 101 so that the damping mechanism 300 can be extended into or moved out of the conveying zone 101. When the damping mechanism 300 is extended into the conveying zone 101, the damping mechanism 300 provides a damping force for the material 11. When the damping mechanism 300 is moved out of the conveying zone, the damping mechanism 300 stops providing resistance to the material 11.

[0108] As shown in FIG. 4 to FIG. 6 , in some embodiments, the damping mechanism 300 includes a damping portion 310 and a damping driver 320 . The damping driver 320 is configured to drive the damping portion 310 to move closer to or farther from the conveying area 101 .

[0109] The damping driver 320 is configured to drive the damping unit 310 to move away from or toward the conveying zone 101. When the damping driver 320 moves the damping unit 310 toward the conveying zone 101, at least a portion of the damping unit 310 moves into the conveying zone 101, requiring the material 11 to exert a certain force on the damping unit 310 before continuing to move forward along the conveying zone 101. When the damping driver 320 moves the damping unit 310 a certain distance away from the conveying zone 101, the damping unit 310 moves outside the conveying zone 101, eliminating resistance to the material 11 and allowing the material 11 to continue to move forward along the conveying zone 101. The direction in which the damping driver 320 drives the damping unit 310 can be inclined relative to the conveying direction. For example, the direction in which the damping driver 320 drives the damping unit 310 is perpendicular to the conveying direction.

[0110] Illustratively, the damping actuator 320 drives the damping unit 310 to move between a third position and a fourth position. In FIG4 , the damping unit 310 is in the third position, with a portion of the damping unit 310 extending into the conveying zone 101. The material 11 in the conveying zone 101 pushes the damping unit 310 to move, allowing it to continue moving in the conveying direction. As shown in FIG5 , the damping unit 310 is in the fourth position. After moving a certain distance in the direction of arrow C from the third position, the damping unit 310 moves to the fourth position, eliminating contact between the damping unit 310 and the material 11 on the conveyor. Because the material 11 must push the damping unit 310 to continue moving forward in the conveying direction, if the amount of material 11 behind the damping unit 310 is small and the resistance provided by the damping unit 310 is excessive, the damping unit 310 can be moved out of the conveying zone 101 to facilitate smooth passage of the material 11 through the conveying zone 101 corresponding to the damping unit 310. Since the amount of the material 11 on the rear side of the damping portion 310 is relatively small, a large impact force will not be exerted on the barrier 220 on the front side.

[0111] In this setting, the damping part 310 can be moved to a position away from the conveying area 101 by the damping driver 320, so that whether to provide resistance for the cup located behind the area opposite to the damping part 310 in the conveying area 101 can be adjusted according to the specific conveying requirements of the cup.

[0112] The damping actuator 320 can be controlled by an operator. For example, after observing that the cups are stagnant in the area opposite the damping unit 310, the operator activates the damping actuator 320 and moves the damping unit 310 to the fourth position. If there are a relatively large number of cups in the area corresponding to the rear side of the damping unit 310, the operator activates the damping actuator 320 and moves the damping unit 310 to the third position, thereby providing resistance to the cups through the damping unit 310.

[0113] As shown in Figure 1, in a possible design, the conveying device 10 also includes a first sensor 400. In the transmission direction, the first sensor 400 is located on the rear side of the damping mechanism 300. When the damping mechanism 300 includes a damping part 310, the first sensor 400 is located on the rear side of the damping part 310. The first sensor 400 is spaced apart from the damping part 310. The first sensor 400 is used to detect whether there is material 11 in the conveying area 101 opposite to the first sensor 400. When the first sensor 400 detects that there is no material 11 in the conveying area 101 opposite to the first sensor 400, the damping driver 320 drives the damping part 310 to move away from the conveying area 101.

[0114] Optionally, the spacing between the first sensor 400 and the damping unit 310 is the size of four to eight materials 11 (this size is the size of the material 11 in the conveying direction), that is, five to eight materials 11 can be accommodated between the damping unit 310 and the first sensor 400. For example, as shown in FIG1 , the spacing between the first sensor 400 and the damping unit 310 is the size of five materials 11. In other words, when there are only five materials 11 behind the damping unit 310, the first sensor 400 detects that there are no materials 11 in the conveying zone 101 opposite it, and the damping driver 320 drives the damping unit 310 to move outward from the conveying zone 101. In this configuration, six materials 11 can smoothly push the damping unit 310 to move without affecting its movement in the conveying direction.

[0115] In this configuration, when the first sensor 400 detects the absence of cups within its corresponding conveying zone 101, the damping actuator 320 drives the damping unit 310 away from the conveying zone 101. Specifically, when the number of cups in front of the damping unit 310 is relatively small, the damping actuator 320 automatically moves the damping unit 310 away from the conveying zone 101 to reduce the resistance to the cups and facilitate their transport. In this configuration, the distance between the damping unit 310 and the first sensor 400 can be calculated based on the resistance of the damping unit 310 to the material 11. Alternatively, the distance between the damping unit 310 and the first sensor 400 can be determined by testing the minimum number of continuously conveyed cups required to move the damping unit 310. The presence of the first sensor 400 eliminates the need for an operator to observe and manually operate the damping actuator 320, enabling more intelligent automatic control. For example, the damping driver 320 and the first sensor 400 may be electrically connected to the same controller. When the first sensor 400 detects that there are no trays in the corresponding conveying zone 101, the first sensor 400 triggers and sends a signal to the controller. The controller controls the damping driver 320 so that the damping driver 320 drives the damping portion 310 to move away from the conveying zone 101. The controller may be an independently operated controller in the conveying device 10, or the controller may be a controller in a battery production line in which the conveying device 10 is applied.

[0116] In some feasible embodiments, the damping driver 320 may include any driving structure such as a motor, a pneumatic cylinder, or a hydraulic cylinder. For example, as shown in FIG6 , the damping driver 320 includes a pneumatic cylinder, which includes a cylinder body and a rod body. One end of the rod body is located within the cylinder body, and the other end is in transmission connection with the damping unit 310 to drive the damping unit 310 to move.

[0117] In some feasible embodiments, the cylinder is connected to two position sensors: a first damping position sensor 321 and a second damping position sensor 322. The first damping position sensor 321 is triggered when the rod drives the damping unit 310 to move to the third position, and the second damping position sensor 322 is triggered when the rod drives the damping unit 310 to move to the fourth position. The first damping position sensor 321 and the second damping position sensor 322 can detect whether the damping unit 310 has moved to its position (to the third position or the fourth position), thereby facilitating closed-loop control of the cylinder. That is, after the cylinder starts and drives the damping unit 310 away from the conveying area 101, if the second damping position sensor 322 is triggered, it indicates that the damping unit 310 has moved to the fourth position, and the cylinder stops driving the damping unit 310. Alternatively, after the air cylinder is activated and drives the damping unit 310 to move toward the conveying area 101, when the first damping position sensor 321 is triggered, indicating that the damping unit 310 has moved to the third position, the air cylinder stops driving the damping unit 310 to move. The first damping position sensor 321 and the second damping position sensor 322 can both be magnetic position sensors.

[0118] As shown in Figures 6 to 8, in a possible design, the damping mechanism 300 also includes a connecting seat 330, the connecting seat 330 includes a first plate 331 and a second plate 332, the first plate 331 is connected to the second plate 332 at an angle, the first plate 331 is connected to the damping driver 320, the damping part 310 is movably mounted on the second plate 332, and the damping driver 320 is located in the space enclosed by the first plate 331 and the second plate 332.

[0119] The damping unit 310 is connected to the damping driver 320 via a connecting base 330. Specifically, the damping driver 320 includes a fixed portion and a driving portion, the driving portion being movable relative to the fixed portion. The connecting base 330 is connected to the fixed portion of the damping driver 320. For example, when the damping driver 320 includes a cylinder, the cylinder includes a cylinder body and a rod body, with the cylinder body serving as the fixed portion and the rod body serving as the driving portion. The first plate 331 of the connecting base 330 is connected to the end of the rod body away from the cylinder body.

[0120] The first plate 331 and the second plate 332 may be connected vertically. For example, as shown in Figures 7 and 8, the first plate 331 is connected to the end of the second plate 332 away from the conveying area 101, and the top of the first plate 331 is connected to the second plate 332. In other words, the space formed between the first plate 331 and the second plate 332 is located on the side of the first plate 331 close to the conveying area 101 and below the second plate 332. The damping unit 310 is connected to the upper side of the second plate 332. In this arrangement, the damping driver 320 is installed below the damping unit 310, and the damping driver 320 and the damping unit 310 are distributed in the height direction, thereby saving installation space for the damping mechanism 300 in the moving direction of the damping unit 310. When the moving direction of the damping part 310 is the width direction of the transmission area 101, this setting method has lower requirements for the space size of the transmission mechanism 100 outside the transmission area 101, which facilitates the installation of the damping mechanism 300 on both sides of the width direction of the transmission area 101.

[0121] The damping part 310 is used to provide resistance for the material 11 without affecting the movement of the material 11 along the conveying direction. That is, after the material 11 moves to the relative position of the damping part 310 along the conveying direction, the material 11 drives the damping part 310 to move, and the damping part 310 will return to its position to contact the subsequent material 11.

[0122] In some feasible embodiments, the damping portion 310 is capable of moving linearly relative to the conveying area 101. The damping mechanism 300 includes a return spring connected to the damping portion 310. The surface of the damping portion 310 opposite the material 11 serves as a guide surface, which is inclined relative to the conveying direction. As the material 11 moves along the conveying direction, the material 11 contacts the guide surface and pushes the damping portion 310 away from the conveying area 101. The return spring accumulates force, and when the material 11 separates from the guide surface, the return spring drives the damping portion 310 into the conveying area 101 to contact the material 11 behind it.

[0123] Alternatively, in some other possible embodiments, the damping unit 310 is capable of rotating relative to the conveying zone 101. As shown in Figures 6 and 7, the damping unit 310 comprises a plurality of teeth spaced circumferentially, with the area between adjacent teeth capable of storing one material 11. As shown in Figure 7, when the damping unit 310 is in the third position, a portion of at least one tooth is located within the conveying zone 101, contacting the material 11. For ease of description, the area between two adjacent teeth is referred to as the buffer zone. The material 11 drives the damping unit 310 in clockwise rotation. In the counterclockwise direction, at least first, second, and third teeth are spaced apart. The area between the first and second teeth constitutes the first buffer zone, and the area between the second and third teeth constitutes the second buffer zone. When the material 11 contacts the first tooth and continues to move in the conveying direction, the material 11 drives the damping unit 310 to rotate and enters the first buffer zone behind the first tooth, allowing the material 11 behind the first tooth to enter the second buffer zone and contact the second tooth. In this arrangement, since the material 11 drives the damping part 310 to rotate, the damping part 310 does not need to be reset and can continuously provide resistance to the material 11.

[0124] As shown in Figures 6 to 9, in a possible design, the damping mechanism 300 also includes a base 340, a pressure piece 350, an angular contact bearing group 360 and a rod 370. The outer ring of the angular contact bearing group 360 is connected to the base 340, and the inner ring of the angular contact bearing group 360 is connected to the rod 370. The pressure piece 350 is located on one side of the axial direction of the angular contact bearing group 360. The pressure piece 350 provides pressure for the angular contact bearing group 360. The damping part 310 is transmission-connected to the rod 370. The damping part 310 can drive the rod 370 to rotate, and the material 11 can push the damping part 310 to rotate.

[0125] The transmission connection between the damping portion 310 and the rod portion 370 can be a fixed connection or a relatively limited connection, that is, the damping portion 310 and the rod portion 370 can rotate synchronously, and the damping portion 310 and the rod portion 370 can move relative to each other or be relatively fixed in the axial direction of the rod portion 370. For example, one of the rod portion 370 and the damping portion 310 is provided with a ridge arranged along the axial direction of the rod portion 370, and the other is provided with a groove arranged along the axial direction of the rod portion 370. When the damping portion 310 and the rod portion 370 are transmission-connected, the ridge is slidably assembled in the groove. Through the cooperation between the ridge and the groove, the damping portion 310 and the rod portion 370 are limited in the rotational direction and slidably assembled in the axial direction.

[0126] Angular contact bearing assembly 360 includes at least one pair of angular contact bearings, arranged axially symmetrically. The angular contact bearings include an inner ring and an outer ring. The contact surfaces of the inner and outer rings are inclined relative to the angular contact bearings, that is, the inner and outer rings are arranged at an angle. Angular contact roller bearings can be used as the angular contact bearings.

[0127] The inner ring of the angular contact bearing assembly 360 is connected to the rod 370, meaning that the inner rings of both angular contact bearings in the angular contact bearing assembly 360 are connected to the rod 370. The outer ring of the angular contact bearing assembly 360 is connected to the base 340, meaning that the outer rings of both angular contact bearings in the angular contact bearing assembly 360 are connected to the base 340. The inner ring of the angular contact bearing is connected to the rod 370, meaning that the inner ring of the angular contact bearing and the rod 370 are relatively limited in rotation. That is, the inner ring of the angular contact bearing and the rod 370 can rotate synchronously about the axis of the angular contact bearing. In the direction of the axis of the angular contact bearing, the inner ring of the angular contact bearing and the rod 370 can be relatively limited in rotation or fixedly connected. For example, the inner ring of the angular contact bearing and the rod 370 can be splined or welded. The outer ring of the angular contact bearing is connected to the base 340. Specifically, the outer ring of the angular contact bearing and the base 340 are relatively limited in the rotational direction. That is, the outer ring and the base 340 can rotate synchronously about the axis of the angular contact bearing. In the direction of the axis of the angular contact bearing, the outer ring and the base 340 can be relatively limited or fixed. For example, the outer ring and the base 340 can be connected by a spline.

[0128] The pressure member 350 provides axial pressure to the angular contact bearing assembly 360 , thereby increasing the pressure between the inner ring and the outer ring of the angular contact bearing assembly 360 , that is, increasing the resistance when the inner ring rotates relative to the outer ring.

[0129] The pressure member 350 may apply a pre-tightening force during the installation process, so that the pressure member 350 provides axial pressure to the angular contact bearing assembly 360 .

[0130] Alternatively, in some embodiments, the pressure member 350 provides pressure to the angular contact bearing assembly 360 via the elastic member 351. In one possible design, the pressure member 350 includes the elastic member 351, and the damping mechanism 300 further includes an adjusting member 380. The elastic member 351 is located between the adjusting member 380 and the angular contact bearing assembly 360. The adjusting member 380 can move relative to the rod 370 to change the amount of compression of the elastic member 351.

[0131] The adjusting member 380 can move relative to the rod 370 and be fixed at multiple different positions to maintain the compression amount of the elastic member 351 at multiple different sizes, thereby providing different pressure values ​​for the angular contact bearing group 360, so that the damping part 310 can provide different resistance values ​​for the material 11.

[0132] In this configuration, the resistance provided by the damping portion 310 to the material 11 can be changed according to factors such as the weight and quantity of the material 11 , so as to adapt to the conveying device 10 for various materials 11 .

[0133] For example, when the weight of the material 11 is relatively light, providing relatively small resistance to the material 11 can meet the demand, and the adjustment member 380 can be moved and fixed to a position so that the compression amount of the elastic member 351 is relatively small, and the pressure provided by the elastic member 351 to the angular contact bearing group 360 is relatively small, so that the resistance that the inner ring of the angular contact bearing group 360 needs to overcome when rotating relative to the outer ring is relatively small, that is, the resistance provided by the damping part 310 to the material 11 is relatively small, and the material 11 requires a relatively small force to push the damping part 310 and continue to move along the conveying direction. When the weight of the material 11 is relatively heavy, providing a relatively large resistance to the material 11 can meet the demand, and the adjustment member 380 can be moved and fixed to another position to make the compression amount of the elastic member 351 relatively large. The elastic member 351 provides a relatively large pressure on the angular contact bearing group 360, so that the resistance that the inner ring of the angular contact bearing group 360 needs to overcome when rotating relative to the outer ring is relatively large, that is, the resistance provided by the damping part 310 to the material 11 is relatively large, and the material 11 requires a relatively large force to push the damping part 310 and continue to move along the conveying direction.

[0134] Since the elastic member 351 is located between the adjusting member 380 and the angular contact bearing group 360, the movement of the adjusting member 380 toward the angular contact bearing group 360 will cause the compression of the elastic member 351 to be greater, and the movement of the adjusting member 380 toward the direction away from the angular contact bearing group 360 will cause the compression of the elastic member 351 to be less.

[0135] In one possible design, the damping portion 310 is provided with a through hole 311, the rod portion 370 passes through the through hole 311, and the angular contact bearing group 360 and the adjustment member 380 are respectively located on both sides of the damping portion 310. The rod portion 370 can be transmission-connected to the inner wall of the through hole 311, so that the damping portion 310 is transmission-connected to the rod portion 370. Alternatively, the damping mechanism 300 also includes a connecting member 390, which is fixedly connected to the damping portion 310, and the connecting member 390 is transmission-connected to the rod portion 370, and the connecting member 390 can drive the rod portion 370 to rotate. In this arrangement, the connection between the connecting member 390 and the damping portion 310 is located outside the through hole 311, and the connection operation is performed outside the through hole 311, which provides a large operating space and facilitates installation.

[0136] The transmission connection between the connecting member 390 and the rod 370 is a relatively limited connection, that is, the connecting member 390 and the rod 370 can rotate synchronously, and the connecting member 390 and the rod 370 can move relative to each other in the axial direction of the rod 370. For example, one of the rod 370 and the connecting member 390 is provided with a ridge arranged along the axial direction of the rod 370, and the other is provided with a groove arranged along the axial direction of the rod 370. When the connecting member 390 and the rod 370 are transmission-connected, the ridge slides and fits in the groove. Through the cooperation of the ridge and the groove, the connecting member 390 and the rod 370 are limited in the rotational direction and slidably assembled in the axial direction.

[0137] The rod portion 370 is inserted through the damping portion 310 to facilitate driving the damping portion 310 to rotate. The angular contact bearing group 360 and the adjustment member 380 are respectively located on either side of the through hole 311, that is, the angular contact bearing group 360 and the adjustment member 380 are respectively located on either side of the damping portion 310. For example, the angular contact bearing group 360 is located below the damping portion 310, and the adjustment member 380 is located above the damping portion 310. Since the angular contact bearing group 360 is located below the damping portion 310, the installation and layout of the angular contact bearing group 360 are facilitated, so that the center of gravity of the damping mechanism 300 is relatively low, and the connection stability is relatively strong. Since the adjustment member 380 is located above the damping portion 310, the adjustment operation is convenient.

[0138] As shown in Figure 9 , in one possible design, the ends of connector 390 contact elastic member 351 and angular contact bearing assembly 360, respectively. In other words, the elastic force of elastic member 351 is transmitted to angular contact bearing assembly 360 via connector 390, thereby applying pressure to angular contact bearing assembly 360. Compared to elastic member 351, connector 390 increases the contact area with angular contact bearing assembly 360, which facilitates applying a relatively more uniform compressive stress to angular contact bearing assembly 360.

[0139] For example, in the vertical direction, the top end of connector 390 contacts elastic member 351, and the bottom end contacts the top surface of angular contact bearing assembly 360. The top end of connector 390 is connected to damping unit 310. The top surface area of ​​connector 390 is larger than the bottom surface area. This larger top surface area allows connector 390 to contact both elastic member 351 and damping unit 310 simultaneously, increasing the contact area with damping unit 310 and improving the connection strength with damping unit 310. The bottom surface area of ​​connector 390 matches the top surface area and shape of angular contact bearing assembly 360 to increase the contact area with the top surface of angular contact bearing assembly 360. Specifically, the bottom surface of connector 390 contacts the top surface of the inner ring of the angular contact bearing in angular contact bearing assembly 360 that is closest to connector 390. A stopper is provided on the rod portion 370 in an area on the side of the angular contact bearing assembly 360 away from the connector 390. The stopper contacts the bottom surface of the inner race of the bearing at the hinge of the angular contact bearing assembly 360, away from the connector 390. The connector 390 and the stopper secure the angular contact bearing assembly 360 to the rod portion 370.

[0140] As shown in Figures 6 to 9, in a possible design, the damping mechanism 300 also includes a scale structure 381, on which scale lines 3811 are provided. One end of the scale structure 381 is in contact with the adjusting member 380, and the other end extends into the through hole 311. The scale structure 381 can move relative to the rod 370 under the drive of the adjusting member 380.

[0141] Due to the different positions of the adjusting member 380 on the rod 370, the compression amount of the elastic member 351 varies, and the compressive stress on the angular contact bearing assembly 360 varies, causing the damping member 310 to provide different resistance to the material 11. There is a positive correlation between the different positions of the adjusting member 380 on the rod 370 and the resistance provided by the damping member 310 to the material 11. In other words, by changing the position of the adjusting member 380 on the rod 370, the resistance provided by the damping member 310 to the material 11 can be varied. Therefore, the scale structure 381 is driven to move by the adjusting member 380, so that the pressure value applied by the pressure member 350 on the angular contact bearing group 360 is reflected by the scale line 3811 on the scale structure 381, or the resistance value provided by the damping part 310 is directly reflected. The relative position of the adjusting member 380 on the rod part 370 can be directly observed by observing the scale line 3811, which is conducive to judging the magnitude of the compressive stress applied to the angular contact bearing group 360, and thus is conducive to judging the magnitude of the resistance provided by the damping mechanism 300 to the support cup.

[0142] The scale line 3811 may indicate a pressure value or a resistance value.

[0143] Since one end of the scale structure 381 extends into the through hole 311, the length of the part of the scale line 3811 located outside the through hole 311 changes with the position of the adjusting member 380, and the scale line 3811 corresponding to the edge of the through hole 311 also changes with the position of the adjusting member 380. The scale line 3811 exposed outside the through hole 311 and closest to the through hole 311 can be used as the identification scale line 3811, that is, the value corresponding to the scale line 3811 is the current value to be read.

[0144] The elastic member 351 can be a spring structure, a disc spring, a coil spring, an elastic block structure (such as a rubber column), etc.

[0145] In one possible design, the elastic member 351 is a spring, which is sleeved on the rod portion 370, and part of the spring is located in the through hole 311. The scale structure 381 has a accommodating cavity 3812, and part of the spring is located in the accommodating cavity 3812. The scale structure 381 contacts the end of the spring away from the angular contact bearing group 360.

[0146] Since the damping portion 310 is connected to the rod portion 370 and the damping portion 310 is provided with a through hole 311 , a spring occupies relatively less space. Specifically, a coil spring can be used as the spring.

[0147] The scale structure 381 has a accommodating cavity 3812. The scale structure 381 can be a cylindrical cover structure. The accommodating cavity 3812 of the scale structure 381 is connected to the through hole 311. The scale structure 381 covers the through hole 311, and the connecting member 390 covers the through hole 311, thereby sealing the spring in the through hole 311 and the accommodating cavity 3812.

[0148] In this arrangement, the scale structure 381 provides a certain degree of protection for the spring, and the relative positions of the scale structure 381 , the spring and the damping portion 310 are more compact, thereby reducing the space occupied by the damping mechanism 300 .

[0149] The adjustment member 380 can be moved relative to the rod 370 and fixed in multiple positions, which can be achieved through a variety of different configurations. For example, the rod 370 is provided with a plurality of first through-holes spaced axially therefrom, and the adjustment member 380 is provided with at least one second through-hole. The damping mechanism 300 also includes a latch that passes through the second through-hole and then extends into one of the first through-holes, thereby securing the adjustment member 380 at one position on the rod 370. The latch is then passed through the second through-hole and then into another first through-hole, securing the adjustment member 380 at another position on the rod 370.

[0150] In another possible embodiment, the rod 370 and the adjusting member 380 are connected by a threaded connection. In one possible design, the rod 370 has external threads, and the adjusting member 380 has a threaded hole that matches the external threads. The adjusting member 380 is threadedly connected to the rod 370 through the threaded hole. In this arrangement, the adjusting member 380 can be moved and fixed to any position within the externally threaded area of ​​the rod 370 by turning it. In this arrangement, the compressive stress applied to the angular contact bearing assembly 360 can be adjusted by turning the adjusting member 380, making the adjustment process convenient.

[0151] In one possible design, the conveying device 10 also includes a counting sensor 500, which includes a detection end 510. A trigger structure 312 is provided on the damping part 310. The damping part 310 moves under the drive of the material 11 to drive the trigger structure 312 to trigger the detection end 510. The counting sensor 500 can record the number of times the detection end 510 is triggered.

[0152] When the damping unit 310 moves linearly relative to the conveying area 101 under the action of the material 11, a trigger structure 312 is provided on the damping unit 310. After the material 11 drives the damping unit 310 to move, the trigger structure 312 triggers the detection end 510, and the counting sensor 500 records the number of times the detection end 510 is triggered + 1.

[0153] When the damping unit 310 rotates relative to the conveying area 101 under the action of the material 11, and the damping unit 310 includes multiple teeth, a buffer zone is defined between adjacent teeth, and a trigger structure 312 is provided for each buffer zone. There is only one detection terminal 510. After the damping unit 310 rotates, the trigger structure 312 corresponding to one buffer zone triggers the detection terminal 510, and the counting sensor 500 records the number of times the detection terminal 510 has been triggered +1. After the damping unit 310 continues to rotate, the trigger structure 312 corresponding to the next buffer zone triggers the detection terminal 510, and the counting sensor 500 records the number of times the detection terminal 510 has been triggered +1.

[0154] For example, the detection end 510 can be a proximity switch, the trigger structure 312 can be a screw, the detection end 510 is arranged below the damping part 310, and the screw extends out of the lower surface of the damping part 310. The setting of the screw facilitates connection with the damping part 310 and is low in cost.

[0155] In one setting, the damping part 310 is connected to the connecting member 390 by a screw. The end of the screw passes through the damping part 310 and the connecting member 390 and extends to the bottom of the connecting member 390. The end of the screw serves as the trigger structure 312. In this setting, the screw is used to connect the connecting member 390 and the damping part 310 on the one hand, and to trigger the counting sensor 500 on the other hand.

[0156] The setting of the counting sensor 500 can be used to detect the number of cups passing through the damping part 310, which is convenient for calculating the number of cups passing through the production line and for implementing the delivery of a set number of cups. For example, when the next device located on the conveying device 10 in the battery production line needs to supply ten cups at a time, after the barrier 220 is moved out of the conveying area 101 to deliver the cups to the next device of the conveying device 10, since multiple cups contact each other in the front and back of the conveying area 101, when one cup is moved out of the conveying device 10, a cup also passes through the damping part 310 at the same time. In other words, the number of cups that have passed through the damping part 310 can be used to determine the number of cups that have been removed from the conveying device 10, thereby facilitating the determination of whether a set number (for example, ten) of cups have been removed from the conveying device 10.

[0157] The counting sensor 500 and the barrier driver 210 can be electrically connected to the same controller. The controller determines whether to activate the barrier driver 210 based on the number of counts from the counting sensor 500, thereby causing the barrier driver 210 to move the barrier member 220 away from the conveying area 101. This controller can be a separate controller within the conveyor device 10, with information inputted to the controller to inform the controller of the set number of cups to be transferred. Alternatively, the controller can be a controller within the battery production line, electrically connected to other equipment within the production line, and comprehensively determine whether to activate the barrier driver 210 based on other data provided by these other devices.

[0158] In one possible design, the damping mechanism 300 also includes a damping mounting seat 301, which is connected to the transmission mechanism 100, and the damping driver 320 is connected to the damping mounting seat 301. One of the damping mounting seat 301 and the second plate 332 is provided with a first slide rail 302, and the other is provided with a first slider 303. The first slider 303 is slidably mounted on the first slide rail 302.

[0159] Since the second plate 332 and the damping mounting seat 301 are slidably connected through the cooperation between the first slider 303 and the first slide rail 302 , the second plate 332 drives the damping part 310 to move relative to the damping mounting seat 301 more stably.

[0160] As shown in Figures 7 and 8, for example, a first slide rail 302 is installed on the damping mounting seat 301, and a first slider 303 is installed on the second plate 332. Since the weight of the first slider 303 is smaller than the weight of the first slide rail 302, the first slide rail 302 does not need to move, and the second plate 332 drives the first slider 303 to move during the movement process. Therefore, the driving force of the damping driver 320 to drive the damping part 310 to move is smaller.

[0161] In one possible design, the second plate 332 is provided with an injection hole 3321, which is disposed opposite the first slider 303. The injection hole 3321 is a through hole that penetrates the second plate 332 along the thickness direction of the second plate 332. For example, the injection hole 3321 is an elongated hole, and the length direction of the elongated hole corresponds to the extension direction of the first slide rail 302, or in other words, the movement direction of the first slider 303.

[0162] In this configuration, lubricant can be added between the first slider 303 and the first slide rail 302 through the injection hole 3321 to improve the smoothness of the movement of the first slider 303 relative to the first slide rail 302. The lubricant can be grease, lubricating oil, etc.

[0163] As shown in Figures 2 and 10, in one possible design, the barrier mechanism 200 includes a barrier driver 210 and a barrier member 220. The barrier driver 210 is configured to drive the barrier member 220 to move away from or toward the conveying area 101. The barrier member 220 includes a limiting end 221. In the conveying direction, the limiting end 221 has a first surface 2211 and a second surface 2212. The first surface 2211 and the second surface 2212 are arranged at an angle relative to each other, and the distance between the first surface 2211 and the second surface 2212 gradually increases in a direction away from the conveying area 101.

[0164] The barrier driver 210 drives the barrier member 220 to move into or away from the conveying zone 101. Specifically, the barrier driver 210 drives the limiting end 221 of the barrier member 220 to move into or away from the conveying zone 101. Driven by the barrier driver 210, at least a portion of the limiting end 221 can extend into the conveying zone 101, thereby limiting the position of the materials 11 within the conveying zone 101. Exemplarily, the barrier driver 210 can move the barrier member 220 between at least a first position within the conveying zone 101 and a second position outside the conveying zone 101. As shown in FIG. 2 , the barrier member 220 is in the first position, with at least a portion of the barrier member 220 moved to the middle region of the conveying zone 101, perpendicular to the conveying direction. For ease of description, the direction perpendicular to the conveying direction is referred to as the width direction of the conveying zone 101. In FIG2 , the end of the barrier 220 is located at the midpoint of the width direction of the conveying zone 101. That is, in the width direction of the conveying zone 101, the barrier 220 blocks at least half of the area of ​​the conveying zone 101 corresponding to the barrier 220. Of course, in other configurations, when the barrier 220 is in the first position, the end of the barrier 220 may extend to the side of the conveying zone 101 away from the blocking driver 210. That is, the barrier 220 completely blocks the area of ​​the conveying zone 101 corresponding to the barrier 220 in the width direction. As shown in FIG3 , barrier member 220 is in the second position. Barrier member 220 does not extend into the area of ​​conveying zone 101 through which material 11 passes. In FIG3 , material 11 is a tray cup, and the width of the tray cup is similar to or equal to the width of conveying zone 101. Therefore, barrier member 220 does not extend into conveying zone 101 at all in the second position. If the width of material 11 is smaller than the width of conveying zone 101, then in conveying device 10 transporting such material 11, barrier member 220 may partially extend into conveying zone 101 at the second position, but will not come into contact with material 11 being transported in conveying zone 101.

[0165] In an embodiment of the present application, the material 11 in the conveying area 101 moves forward along the conveying direction. When at least part of the structure of the limiting end 221 extends into the conveying area 101, under the limiting action of the limiting end 221, the material 11 is blocked at the rear side of the limiting end 221 to prevent the remaining material 11 from continuing to move forward along the conveying direction. The first surface 2211 and the second surface 2212 are arranged at an angle relative to each other, specifically referring to the first surface 2211 and the second surface 2212 being arranged at an angle less than or greater than 90 degrees. In the conveying direction, the distance between the first surface 2211 and the second surface 2212 gradually increases in the direction away from the conveying area 101, that is, in the conveying direction, the size of the limiting end 221 gradually increases in the direction away from the conveying area 101. As can be seen, in this arrangement, in the conveying direction, the dimension of the end of the limiting end 221 closer to the conveying area 101 is smaller than the dimension of the end of the limiting end 221 farther from the conveying area 101, so that the limiting end 221 can more smoothly extend between two adjacent materials 11 in the conveying area 101. This, to a certain extent, prevents the limiting end 221 of the barrier 220 from squeezing the materials 11 toward the conveying area 101 when the barrier 220 moves toward the conveying area 101. In other words, in this arrangement, the dimension of the barrier 220 closer to the conveying area 101 is relatively smaller, making it easier for the barrier 220 to extend between two adjacent cups.

[0166] In some embodiments, the first surface 2211 and the second surface 2212 can both be arranged at an angle relative to the transport direction. For example, the transport mechanism 100 includes a first wall and a second wall spaced apart from each other, with the transport zone 101 located between the first wall and the second wall. The first wall and the second wall are both arranged parallel to the transport direction, with the first wall being further away from the barrier mechanism 200 than the second wall. The first surface 2211 and the second surface 2212 are both arranged at an angle relative to the first wall or the second wall. The distance between the first surface 2211 and the first wall gradually decreases along the transport direction, while the distance between the second surface 2212 and the first wall gradually increases along the transport direction.

[0167] In one possible design, the first surface 2211 is located behind the second surface 2212 in the conveying direction, with the first surface 2211 being perpendicular to the conveying direction. When at least a portion of the retaining end 221 extends into the conveying zone 101, as shown in Figures 2 and 11, the material 11 behind the retaining end 221 is blocked there, and the first surface 2211 is subjected to the compressive force of the material 11 along the conveying direction. In this arrangement, since the first surface 2211 is perpendicular to the conveying direction, the reaction force exerted by the first surface 2211 on the material 11 is precisely opposite to the conveying direction, thereby enhancing the retaining effect of the retaining end 221 on the material 11. Furthermore, since the first surface 2211 is perpendicular to the conveying direction, the force exerted by the material 11 on the first surface 2211 is perpendicular to the first surface 2211. This improves the support effect of the retaining end 221 and prevents breakage of the retaining end 221 to a certain extent.

[0168] In one possible design, as shown in FIG10 , a buffer structure 231 is installed on the first surface 2211. The buffer structure 231 is used to buffer the material 11. The buffer structure 231 can be made of a flexible material, such as polyurethane, polyether, or polyurethane polyether. The buffer structure 231 can be columnar, block-shaped, plate-shaped, or other irregular shapes. In this arrangement, when at least part of the structure of the limit end 221 extends into the conveying area 101, the buffer structure 231 can buffer the movement of the material 11 behind the limit end 221, so as to reduce the buffering force on the material 11, thereby providing better protection for the material 11 to a certain extent.

[0169] In one possible design, as shown in FIG10 , the first surface 2211 is provided with a bezel 232. The buffer structure 231 is cylindrical and is mounted in the bezel 232, with a portion of the buffer structure 231 located outside the bezel 232. The bezel 232 is used to limit the buffer structure 231 so that the buffer structure 231 is stably mounted on the first surface 2211. A portion of the buffer structure 231 is located outside the bezel 232, that is, a portion of the buffer structure 231 protrudes from the first surface 2211 through the bezel 232. Alternatively, it can be understood that in a direction perpendicular to the first surface 2211, the size of the buffer structure 231 is larger than the size of the bezel 232. In this arrangement, by providing the bezel 232, a portion of the buffer structure 231 is located inside the limiting end 221, thereby saving space. Because the buffer structure 231 is cylindrical, the opening of the bezel 232 along the radial direction of the buffer structure 231 only needs to be smaller than the diameter of the buffer structure 231. The opening of the bezel 232 restrains the buffer structure 231, ensuring that the buffer structure 231 is stably mounted within the bezel 232. Furthermore, a portion of the buffer structure 231 can extend from the opening of the bezel 232, so that the portion of the buffer structure 231 is positioned outside the bezel 232. Alternatively, the bezel 232 can be prismatic, cylindrical, or any other shape, with the opening of the bezel 232 along the radial direction of the buffer structure 231 being smaller than the diameter of the buffer structure 231. Exemplarily, the bezel 232 is cylindrical, matching the shape of the buffer structure 231, so that a portion of the outer surface of the buffer structure 231 can be well aligned with the inner surface of the bezel 232. This improves the installation stability of the buffer structure 231.

[0170] In one possible design, as shown in Figures 10 to 12, there are multiple limit ends 221, and the multiple limit ends 221 are spaced apart in a direction perpendicular to the transmission direction. The direction perpendicular to the transmission direction can specifically be a direction perpendicular to the transmission direction in a horizontal plane, a direction perpendicular to the transmission direction in a vertical plane, or a direction perpendicular to the transmission direction in any other plane. In this arrangement, by providing multiple limit ends 221 to block the material 11 in the conveying area 101, the contact area between the material 11 and the barrier 220 is increased, thereby improving the stability of the barrier 220 in blocking the material 11.

[0171] In some optional embodiments, the conveying direction is horizontal, and multiple limiting ends 221 are spaced apart in the vertical direction. For example, there are two limiting ends 221, which are spaced apart in the vertical direction. The lower limiting end 221 is used to abut the bottom of the material 11, and the higher limiting end 221 is used to abut the top of the material 11. In this arrangement, the two limiting ends 221 can abut the upper and lower ends of the material 11, effectively preventing the material 11 from falling after hitting the limiting ends 221, and the barrier 220 has a high reliability in blocking the material 11. If the size of the material 11 in the vertical direction is large, in this case, since multiple limit ends 221 are arranged at intervals along the vertical direction, taking the number of limit ends 221 as two as an example, one of the limit ends 221 abuts against the bottom of the material 11, and the other limit end 221 abuts against the middle of the material 11. In this way, it can also effectively prevent the material 11 from tipping over after hitting the limit end 221, and the barrier 220 has better stability in blocking the material 11.

[0172] In one possible design, the barrier mechanism 200 further includes a barrier mounting base 201. One of the barrier mounting base 201 and the barrier member 220 is provided with a second slide rail 202, and the other is provided with a second slider 203. The second slider 203 is slidably mounted on the second slide rail 202. The barrier mounting base 201 is used to mount the second slider 203 or the second slide rail 202. The barrier mounting base 201 can be a plate-shaped structure, a block-shaped structure, or other irregularly shaped structure. The second slider 203 is slidably mounted on the second slide rail 202, thereby allowing the barrier member 220 to be slidably mounted on the barrier mounting base 201. The barrier mounting base 201 can be fixedly connected to the conveying mechanism 100, or it can also be fixedly connected to a surface (such as the ground or a workbench) used to mount the conveying device 10. The barrier mounting base 201 provides stable support for the barrier member 220, and when the barrier member 220 slides relative to the barrier mounting base 201, the barrier member 220 can move relative to the conveying area 101. The second slide rail 202 is used to support the second slider 203. The second slide rail 202 is specifically a strip-shaped structure, and the direction of extension of the second slide rail 202 is parallel to the direction of approaching or moving away from the conveying area 101. The second slider 203 is slidably mounted on the second slide rail 202. Specifically, the second slider 203 can have a slide groove, and a portion of the second slide rail 202 is inserted into the slide groove, allowing the second slider 203 to slide along the extension direction of the second slide rail 202, thereby allowing the barrier member 220 to move relative to the barrier mounting base 201 toward or away from the conveying area 101. In this arrangement, the second slider 203 and the second rail 202 are provided to make the movement of the barrier 220 relative to the barrier mounting base 201 smoother, thereby improving the smoothness of the movement of the barrier 220 toward or away from the transfer area 101. In some alternative embodiments, the second rail 202 is provided on the barrier mounting base 201, and the second slider 203 is provided on the barrier 220.

[0173] In one possible design, the blocking mechanism 200 also includes a third plate 204 and a fourth plate 205, and the third plate 204 and the fourth plate 205 are connected to each other at a relative angle, and the blocking driver 210 is installed in the area enclosed by the third plate 204 and the fourth plate 205, and the blocking driver 210 is transmission-connected to the third plate 204, and the limit end 221 is connected to the fourth plate 205.

[0174] The third plate 204 and the fourth plate 205 are connected at an angle relative to each other, that is, the third plate 204 and the fourth plate 205 are arranged at an angle, the angle between the third plate 204 and the fourth plate 205 is greater than 0 degrees and less than 180 degrees, and the third plate 204 and the fourth plate 205 are connected to each other. The third plate 204 and the fourth plate 205 can be connected by bonding, welding, clamping, or connecting with auxiliary connecting members 390 (screws or bolts, etc.), or the third plate 204 and the fourth plate 205 can also be connected by integral injection molding or integral casting. Optionally, the third plate 204 and the fourth plate 205 are arranged vertically and connected to each other, the third plate 204 is arranged parallel to the vertical direction, and the fourth plate 205 is arranged parallel to the horizontal direction.

[0175] The barrier actuator 210 is mounted within the area enclosed by the third plate 204 and the fourth plate 205. That is, because the third and fourth plates 204, 205 are arranged at an angle relative to each other, a region is defined between the third and fourth plates 204, 205, within which the barrier actuator 210 is located. Alternatively, the third and fourth plates 204, 205 are located on different sides of the barrier actuator 210. Alternatively, the barrier actuator 210 may be mounted on the barrier mounting base 201, which supports the barrier actuator 210 within the region enclosed by the third and fourth plates 204, 205.

[0176] The barrier driver 210 is in driving connection with the third plate 204; that is, the barrier driver 210 is capable of driving the third plate 204 to move. Exemplarily, the barrier driver 210 has a driving end, and the third plate 204 is connected to the driving end of the barrier driver 210. Specifically, the driving end of the barrier driver 210 is fixedly connected to the third plate 204. The driving end of the barrier driver 210 drives the third plate 204 to move, thereby driving the fourth plate 205 and the stopper 221 connected thereto. The third plate 204 and the driving end of the barrier driver 210 can be connected by any connection method, including gluing, clamping, welding, or connection with auxiliary connectors 390 (screws or bolts, etc.), which are not limited herein.

[0177] The limiting end 221 is connected to the fourth plate 205. Specifically, the limiting end 221 is connected by bonding, welding, adhesion, clamping or auxiliary connecting parts 390 (screws or bolts, etc.), or the fourth plate 205 is connected to the limiting end 221 by integral injection molding or integral casting.

[0178] In this arrangement, the barrier driver 210 is installed in the area enclosed by the third plate 204 and the fourth plate 205 , so that the barrier driver 210 is better protected by the third plate 204 and the fourth plate 205 .

[0179] In some optional embodiments, the fourth plate 205 is connected to the limiting end 221 of the barrier member 220, the third plate 204 is located below the fourth plate 205, and the third plate 204 is located on the side of the fourth plate 205 away from the conveying mechanism 100, and the barrier driver 210 is located below the fourth plate 205 and between the third plate 204 and the conveying mechanism 100. Alternatively, the barrier driver 210 may be mounted on the conveying mechanism 100, with the driving end of the barrier driver 210 connected to the third plate 204. The driving end of the barrier driver 210 drives the third plate 204 to move toward or away from the conveying mechanism 100, thereby driving the fourth plate 205 and the limiting end 221 connected to the fourth plate 205 to move toward or away from the conveying area 101. When the limiting end 221 is driven away from the conveying area 101 by the blocking driver 210, at least part of the structure of the limiting end 221 can be located above the blocking driver 210. Thus, in this embodiment, by installing the blocking driver 210 between the third plate 204 and the conveying mechanism 100, the space occupied by the conveying device 10 in the moving direction of the blocking member 220 can be reduced.

[0180] In some optional embodiments, the limiting end 221 is located on the side of the fourth plate 205 facing the transmission area 101, so that the barrier driver 210 can drive the limiting end 221 to extend into the transmission area 101. The limiting end 221 and the fourth plate 205 are connected by an integral molding method, which can be an integral injection molding method or an integral casting method, and the specific method can be determined based on the materials of the limiting end 221 and the fourth plate 205. For example, when the limiting end 221 and the fourth plate 205 are both made of plastic material, the limiting end 221 and the fourth plate 205 can be connected by an integral injection molding method. Optionally, the second slider 203 is specifically disposed on the side of the fourth plate 205 and the limiting end 221 facing the barrier mounting seat 201, and the integral structure formed by the fourth plate 205 and the limiting end 221 is connected to the second slider 203 by screws.

[0181] In some optional embodiments, the barrier driver 210 can include any drive structure, such as a motor, a pneumatic cylinder, or a hydraulic cylinder. The barrier driver 210 drives the limit end 221 to move between a first position and a second position, that is, the barrier driver 210 drives the limit end 221 to extend into or away from the conveying area 101. The barrier driver 210 is connected to a first barrier position sensor 211 and a second barrier position sensor 212. When the barrier driver 210 drives the limit end 221 to the first position, the first barrier position sensor 211 is triggered; when the barrier driver 210 drives the limit end 221 to the second position, the second barrier position sensor 212 is triggered. The provision of the first barrier position sensor 211 and the second barrier position sensor 212 facilitates closed-loop control of the barrier driver 210. Both the first barrier position sensor 211 and the second barrier position sensor 212 can be magnetic position sensors.

[0182] In one possible design, the conveying device 10 further includes a second sensor 600. The second sensor 600 is located behind the barrier 220 in the conveying direction and spaced apart from the barrier 220. The second sensor 600 is configured to detect the presence of the material 11 in the conveying zone 101 opposite the second sensor 600. The second sensor 600 may be a photoelectric sensor, an acoustic sensor, a laser sensor, an infrared sensor, or the like, without limitation herein.

[0183] Optionally, the distance between the second sensor 600 and the barrier 220 is the size of 4-8 items 11 (this size is the size of the item 11 in the conveying direction), that is, 5-8 items 11 can be accommodated between the barrier 220 and the second sensor 600. For example, as shown in FIG1 , the distance between the second sensor 600 and the barrier 220 is the size of 5 items 11. That is, when there are only five items 11 behind the barrier 220, the second sensor 600 detects that there are no items 11 in the conveying zone 101 opposite to the barrier 220.

[0184] In this configuration, since the second sensor 600 is located behind the barrier 220, it can detect whether material 11 is being transported to the barrier 220 at a distance therefrom, thereby facilitating a determination as to whether the material 11 needs to be blocked or released. For example, the multiple conveying devices 10 are all electrically connected to the same controller. Specifically, the controller is signal-connected to the barrier driver 210 and the second sensor 600 in each conveying device 10. When the second sensors 600 of two or more conveying devices 10 simultaneously detect the presence of materials 11 in their respective conveying areas 101, the controller can timely adjust the operation of the blocking actuators 210 in each conveying device 10 based on the information fed back by the second sensors 600 of each conveying device 10. For example, as shown in FIG3 and FIG12 , the controller controls the blocking actuator 210 of one conveying device 10 to drive the corresponding limiting end 221 to the second position, so that the materials 11 in the conveying area 101 of the conveying device 10 can move forward smoothly along the transmission direction. The controller controls the blocking actuators 210 in the other conveying devices 10 to drive the corresponding limiting end 221 to the first position, as shown in FIG2 and FIG11 , so that the materials 11 in the conveying areas 101 of the other conveying devices 10 are temporarily blocked by the limiting end 221. This facilitates the orderly transportation of the materials 11 in each conveying device 10.

[0185] In some optional embodiments, the second sensor 600 includes a second transmitting end and a second receiving end, which are spaced apart in a direction perpendicular to the transmission direction and located on opposite sides of the conveying zone 101. The second transmitting end is configured to transmit a signal to the second receiving end. The signal transmitted by the second transmitting end may be a light signal, an acoustic signal, or the like. When material 11 passes through the conveying zone 101 corresponding to the second transmitting end and the second receiving end, the material 11 blocks the signal transmitted by the second transmitting end to the second receiving end, thereby determining whether material 11 is present in the conveying zone 101.

[0186] In one possible design, the conveying mechanism 100 includes a frame 110, with the conveying area 101 located on the frame 110. The blocking mechanism 200 and the damping mechanism 300 are respectively mounted on the frame 110. The frame 110 can be a frame structure, that is, it can be composed of a plurality of overlapping support rods. Alternatively, the frame 110 can be a base structure, with multiple mounting platforms for mounting the blocking mechanism 200 and the damping mechanism 300. In this arrangement, the frame 110 facilitates the installation of the blocking mechanism 200 and the damping mechanism 300.

The damping actuator 320 is mounted on the third connecting plate, and the end of the damping actuator 320 remote from the third connecting plate is connected to the first plate 331. If the damping actuator 320 includes a cylinder, the cylinder body of the damping actuator 320 is mounted on the third connecting plate, and the end of the rod body remote from the cylinder body is connected to the first plate 331.

[0190] In one possible design, the frame 110 is provided with a first trough 111, and the blocking mechanism 200 is installed at the first trough 111; and / or, the frame 110 is provided with a second trough 112, and the damping mechanism 300 is installed at the second trough 112.

In this arrangement, the inner wall of the first trough 111 restrains the blocking mechanism 200, and the inner wall of the second trough 112 restrains the damping mechanism 300, so that the blocking mechanism 200 and the damping mechanism 300 are stably mounted on the frame 110.

When there are multiple damping mechanisms 300, in the transmission direction, the multiple damping mechanisms 300 are all installed on the rear side of the blocking mechanism 200, and the multiple damping mechanisms 300 are spaced apart along the transmission direction. Since the strip grooves extend along the transmission direction, the installation position of the blocking mechanism 200 or the damping mechanism 300 can be adjusted along the transmission direction according to actual needs, which improves applicability.

[0196] The barrier mechanism 200 includes a barrier mount 201, a barrier driver 210, a barrier member 220, a first stopper 2011, a third plate 204, and a fourth plate 205. The barrier mount 201 includes a first connecting plate and a second connecting plate, which are arranged vertically. The first connecting plate is located on the side of the second connecting plate closest to the frame 110, and the second connecting plate is connected to the top of the first connecting plate. One end of the first stopper 2011 is connected to the first connecting plate of the barrier mount 201, and the other end extends into the first slot 111, ensuring a stable installation of the barrier mount 201 on the frame 110. The third plate 204 and the fourth plate 205 are arranged vertically and interconnected. The fourth plate 205 is located above the second connecting plate and is connected to the barrier member 220. The third plate 204 is located on the side of the second connecting plate away from the first connecting plate. The third plate 204, the second connecting plate, and the first connecting plate enclose a storage area below the fourth plate 205. A barrier driver 210 is located in the storage area.

The barrier member 220 includes a limiting end 221, which is connected to the fourth plate 205 and forms an integral structure with the fourth plate 205. The driving end of the barrier driver 210 drives the third plate 204 toward or away from the conveying mechanism 100, thereby driving the fourth plate 205 and the limiting end 221 connected to the fourth plate 205 toward or away from the conveying area 101. Driven by the blocking driver 210, at least a portion of the limiting end 221 can extend into the conveying area 101 to limit the material 11 within the conveying area 101. There are two limiting ends 221, spaced apart vertically. The limiting end 221 has a first surface 2211 and a second surface 2212. In the conveying direction, the first surface 2211 is located behind the second surface 2212 and perpendicular to the conveying direction. The first surface 2211 and the second surface 2212 are inclined relative to each other, with the distance between the first surface 2211 and the second surface 2212 gradually increasing away from the conveying area 101. The first surface 2211 is provided with a bezel 232, within which a cylindrical buffer structure 231 is mounted. In the radial direction of the buffer structure 231, the opening of the bezel 232 is smaller than the diameter of the buffer structure 231, and a portion of the buffer structure 231 extends from the opening of the bezel 232. The buffer structure 231 is made of a flexible material, including but not limited to polyurethane, polyether, or polyurethane polyether. The buffer structure 231 cushions the movement of the material 11 behind the stopper end 221, thereby reducing the impact force on the material 11. The bezel 232 is cylindrical in shape, matching the shape of the buffer structure 231.A second slide rail 202 is provided on the top surface of the second connecting plate, and a second slider 203 is provided on the bottom surface of the fourth plate 205 and the limiting end 221. The second slide rail 202 extends parallel to the direction of approach or distance from the conveying area 101. The second slider 203 is slidably mounted on the second slide rail 202. The conveying device 10 also includes a second sensor 600, which is mounted on the frame 110 and is located behind the barrier 220 in the conveying direction. The second sensor 600 is spaced apart from the barrier 220, and the spacing between the second sensor 600 and the barrier 220 is the size of 4-8 materials 11.

[0197] In a second aspect, a battery production line is provided, comprising a conveying device 10 as provided in any of the aforementioned embodiments. Because the battery production line utilizes the aforementioned conveying device 10, the impact force of the cups on the barrier 220 in the conveying device 10 during the conveying of the cups can be reduced, thereby extending the service life of the barrier 220. Furthermore, the pressure between adjacent cups can be reduced, facilitating the removal of multiple cups from a plurality of cups for testing or other operations.

[0198] The battery production line further includes a first device and a second device, and the conveying device 10 is used to transport the material 11 of the first device to the second device.

[0199] As shown in FIG13 , in a possible design, there are multiple conveying devices 10 , and the production line further includes a confluence device, which includes a confluence area, and the transmission areas 101 of the multiple conveying devices 10 are respectively connected to the confluence area.

[0200] There are multiple conveying devices 10, and the multiple conveying devices 10 all convey the material 11 to the converging device, and the converging device continues to convey the material 11 to the second equipment.

[0201] For example, there are multiple first devices and one second device, and a conveying device 10 is provided between each first device and the second device. The number of conveying devices 10 is the same as the number of first devices. One end of each conveying device 10, along the rear side of the conveying direction, is positioned opposite the corresponding first device, so that material 11 from the first device enters the conveying device 10. One end of the conveying device 10, along the front side of the conveying direction, is connected to a confluence device, so that material 11 in the conveying device 10 can be transferred to the confluence device. The confluence device is positioned opposite the second device, so that material 11 from the confluence device can be transferred to the second device.

[0202] Since the blocking mechanism 200 and the damping mechanism 300 are provided in each of the plurality of conveying devices 10 , it is convenient to convey the material 11 to the merging device through the plurality of conveying devices 10 .

[0203] In some embodiments, a battery production line includes a controller. For example, as shown in FIG13 , there are two conveying devices 10. In each of the two conveying devices 10, the barrier driver 210 of the barrier mechanism 200, the damping driver 320 of the damping mechanism 300, the counting sensor 500, the first sensor 400, the second sensor 600, and the confluence device are all electrically connected to the controller. When a confluence device needs to load material, the first sensor 400 can be used to determine which conveying device 10 has material 11 behind its barrier 220. If one conveying device 10 has material 11 and the other does not, the barrier driver 210 in the conveying device 10 with material 11 is activated, causing the barrier 220 to move out of the transfer zone 101, allowing the material 11 in that conveying device 10 to be transferred to the confluence device. When material 11 is present behind the barrier members 220 of both conveying devices 10, the barrier driver 210 of the first conveying device 10 is activated in a predetermined sequence, causing the barrier member 220 to move out of the conveying area 101, thereby transferring a set amount of material 11 from the conveying device 10 to the merging device. When the controller determines, based on the counting sensor 500 of the conveying device 10 that is conveying material 11, that the quantity of conveyed material 11 has reached a set quantity, the controller controls the barrier driver 210 of the conveying device 10 to move to the conveying area 101, thereby stopping the conveying of material 11 by the conveying device 10. The controller then activates the barrier driver 210 of the other conveying device 10, causing the barrier member 220 to move out of the conveying area 101, thereby transferring a set amount of material 11 from the conveying device 10 to the merging device. This cycle continues until the merging device indicates that there is no material feeding demand.

[0204] The controller may include a PLC.
