Description

Technical Field

[0001] The present application relates to the technical field of material handling, and in particular to a receiving device and an assembly line. Background Art

[0002] The receiving device is a device used to receive a target object, for example, a tray, an electrode assembly support cup, etc.

[0003] Taking the electrode assembly support cup as an example, the electrode assembly support cup is used to receive the electrode assembly and move on the logistics line so that the electrode assembly can reach the position of the corresponding process to receive the corresponding processing.

[0004] At present, most logistics lines will set up channels according to actual needs, and contact the target object in the moving process through the channel edge of the channel to guide the target object to move in a specific direction. However, the target object received by the current receiving device is usually relatively fixed on the receiving device. As a result, when the target object contacts the channel edge during movement, the target object and the channel edge usually slide and rub. This ultimately leads to the problem that the target object is easily scratched by the channel edge. Utility Model Content

[0005] In view of this, an object of the embodiments of the present application is to provide a receiving device and an assembly line to improve the problem in the prior art that the target object received by the receiving device is easily scratched.

[0006] In order to solve the above problems, on the first aspect, an embodiment of the present application provides a receiving device, which includes a shell and a receiving part; the shell includes a first end connected to the receiving part and a second end forming an opening; the shell forms a accommodating space around; the accommodating space is configured to partially accommodate a target object received from the opening; the receiving part includes a movable connecting part; the movable connecting part is configured to receive the target object and, based on the force applied to the target object, rotate relative to the shell.

[0007] In the technical solution of the embodiment of the present application, by providing a movable connection part at the bottom of the receiving device, it is achieved that when the target object is received in the receiving device, it can rotate relative to the shell according to the force on the target object. When the target object received by the receiving device is in contact with the outside during the movement, the sliding friction when the target object contacts the outside is converted into rolling friction by rotating relative to the shell. For example: in the process of being guided to move in a specific direction by contacting the edge of the channel on the logistics line, the target object can convert the sliding friction between the target object and the edge of the channel into rolling friction by rotating relative to the shell. Ultimately, the probability of the target object being scratched is reduced.

[0012] In the technical solution of the embodiment of the present application, the first groove and the second groove are respectively provided on the second connection part and the rotating member, and the first groove and the second groove are used to clamp the first slidable member. On the basis of realizing the rotatable connection between the rotating member and the base through this ball bearing-like structure, the resistance between the rotating member and the second connection part is also reduced, so that when the target object is received in the receiving device, it can rotate relative to the shell more smoothly according to the force of the target object. In addition, the probability of the target object being scratched is further reduced.

[0013] In some embodiments, the device further comprises a connector; interconnected through holes are provided at the connection between the first connector and the shell; the connector is configured to be inserted into the interconnected through holes to fix the first connector and the shell.

[0014] In the technical solution of the embodiment of the present application, the first connecting member is inserted into the through hole interconnected at the connection between the first connecting part and the shell, thereby realizing a detachable connection between the base and the shell.

Similarly, a simple structure is used to achieve that when the target object is received in the receiving device, it can rotate relative to the shell according to the force applied to the target object. On the basis of reducing the probability of the target object being scratched, the structure of the receiving device is simplified.

[0018] In the technical solution of the embodiment of the present application, by respectively opening the third groove and the fourth groove on the first rotating connection end and the second rotating connection end, and using the third groove and the fourth groove to clamp the second slidable member, the first rotating connection end and the second rotating connection end are rotatably connected through this ball bearing-like structure, and the resistance between the first rotating connection end and the second rotating connection end is also reduced, so that when the target object is received in the receiving device, it can rotate relative to the shell more smoothly according to the force of the target object. Furthermore, the probability of the target object being scratched is also further reduced.

[0019] In some embodiments, the target object comprises a cylindrical object, the shell comprises a cylindrical shell surrounding a cylindrical accommodating space; a radial dimension of the opening is larger than a radial dimension of the accommodating space; wherein the radial direction is perpendicular to the direction of the opening.

[0020] In the technical solution of the embodiment of the present application, the radial size of the opening can be larger than the radial size of the accommodating space, which plays a role in guiding the target object into the accommodating space, making it easier for the target object to enter the accommodating space.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0037] Reference to "embodiment" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0038] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0039] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0040] The term "plurality" used in the present application refers to two or more (including two).

[0041] At present, when the electrode assembly is placed upright in a receiving device such as a cup, the friction between the electrode assembly and the cup is large during the process of passing through the logistics line diversion port, and the electrode assembly is not easy to rotate relative to the cup, which makes it very easy for the diversion port to scratch the electrode assembly. Among them, the logistics line diversion port guides the electrode assembly through the edge of its channel, and diverts the cup that receives the electrode assembly from the cup that does not receive the electrode assembly.

[0042] In order to improve this problem, the target object can be made to rotate relative to the receiving device when it is received in the receiving device, so that when the target object received by the receiving device comes into contact with the outside during the movement, the sliding friction when the target object comes into contact with the outside can be converted into rolling friction by rotating relative to the receiving device.

[0043] The receiving device is mostly used to receive the target object, and when receiving the target object, it is sent to the target station through the logistics line for the corresponding workstation. For example: the electrode assembly is received by the receiving device and enters the next station along the logistics line for the corresponding process. Another example: cylindrical silicon rods that can be cut into round silicon wafers, optical glass used to manufacture lenses, precision bearings, etc. When these target objects are received by the receiving device, it is possible that the target objects will come into contact with the corresponding parts on the logistics line during the process of being transferred by the logistics line. This contact usually causes the target object to be scratched, which in turn affects the accuracy, performance, and aesthetics of the target object.

[0044] In order to achieve relative rotation between the target object 20 and the receiving device 100, the embodiment of the present application further provides a receiving device 100. Figure 1 and Figure 2 , Figure 1This is a first stereoscopic view of the receiving device 100 provided in some embodiments of the present application; Figure 2 It is a second stereoscopic view of a receiving device 100 provided in some embodiments of the present application. According to some embodiments of the present application, with a receiving device 100 of one embodiment of the present application, the receiving device 100 may include a shell 110 and a receiving portion 120. The shell 110 may include a first end 111 connected to the receiving portion 120 and a second end 112 forming an opening 1121. The shell 110 may be surrounded by a receiving space. The receiving space may be configured to partially accommodate a target object 20 received from the opening 1121. The receiving portion 120 may include a movable connecting portion 121. The movable connecting portion 121 may be configured to receive the target object 20 and, based on the force applied to the target object 20, rotate relative to the shell 110.

[0045] The housing 110 and the accommodation space formed by the housing 110 may be cylindrical, prismatic, or other shapes. The shape of the housing 110 and the accommodation space formed by the housing 110 may also match the shape of the target object 20 .

[0046] The accommodation space is configured to partially accommodate the target object 20 received from the opening 1121, which may mean that, when the target object 20 is accommodated, a portion of the target object 20 is located in the accommodation space, and another portion is located outside the accommodation space. The portion located outside the accommodation space can contact the edge of the channel 200 when the target object 20 is guided to move in a specific direction.

[0047] The receiving portion 120 may include other parts in addition to the movable connecting portion 121. In other words, the movable connecting portion 121 is only a part of the receiving portion 120. The receiving portion 120 may also include only the movable connecting portion 121, that is, the entire receiving portion 120 is the movable connecting portion 121.

[0048] The movable connection part 121 may be a rotary bearing disposed at the bottom of the housing 110 , that is, at the second end 112 of the housing 110 . It may also be other rotating parts 1211 .

[0049] For example, a part of the receiving devices 100 on the logistics line do not receive any target object 20, and another part of the receiving devices 100 receive target objects 20. The receiving devices 100 that do not receive any target object 20 do not have any contact with the channel 200 because their height does not reach the edge of the channel 200, and thus the receiving devices 100 that do not receive any target object 20 cannot be guided to move in a specific direction. The receiving devices 100 that receive target objects 20 can contact with the channel 200 because the height of the received target object 20 reaches or exceeds the edge of the channel 200. In the process of the movement of the received target object 20, it can move in a specific direction under the guidance of the edge of the channel 200.

[0050] In the above implementation process, by setting a movable connection part 121 at the bottom of the receiving device 100, it is achieved that when the target object 20 is received in the receiving device 100, it is relative to the shell 110 according to the force applied to the target object 20. When the target object 20 received by the receiving device 100 is in contact with the outside during the movement, the target object 20 is relatively rotated with the shell 110, thereby converting the sliding friction when the target object 20 is in contact with the outside into rolling friction. For example: in the process of being guided to move in a specific direction by contacting the edge of the channel 200 on the logistics line, the target object 20 is relatively rotated with the shell 110 to convert the sliding friction between the target object 20 and the edge of the channel 200 into rolling friction. Finally, the probability of the target object 20 being scratched is reduced.

[0051] Please combine Figure 2 Reference Figure 3 , Figure 3 It is a first cross-sectional view of the receiving device 100 provided in some embodiments of the present application. According to some embodiments of the present application, the receiving portion 120 may further include a base 122. The movable connecting portion 121 may include a rotating member 1211. The base 122 may include a first connecting portion 1221 fixedly connected to the shell 110 and a second connecting portion 1222 arranged near the middle of the accommodating space. The second connecting portion 1222 may be rotatably connected to the rotating member 1211. The rotating member 1211 may be configured to receive the target object 20 and, based on the force applied to the target object 20, rotate relative to the first connecting portion 1221.

[0052] The first connection portion 1221 may be a portion of the periphery of the base 122 , and the connection between the first connection portion 1221 and the housing 110 may be an integrally formed, welded, or detachably connected.

[0053] The second connection part 1222 can be a part relatively close to the middle of the base 122, and the rotatable connection between it and the movable connection part 121 can be achieved by a rotating axis set on the second connection part 1222 or the movable connection part 121; it can also be a structure similar to a ball bearing, and a ball is set between the second connection part 1222 and the movable connection part 121 to achieve it.

[0054] The rotation axis of the rotating member 1211 may be parallel to the distribution direction of the first end 111 and the second end 112. The rotating member 1211 may be in a disc or annular shape, etc., and may be used to receive the target object 20 received by the accommodation space.

[0055] In the above implementation process, by rotatably setting the rotating member 1211 on the base 122 of the receiving device 100, and using the rotating member 1211 to receive the target object 20, a simple structure is used to achieve that when the target object 20 is received in the receiving device 100, it can rotate relative to the housing 110 according to the force applied to the target object 20. On the basis of reducing the probability of the target object 20 being scratched, the structure of the receiving device 100 is simplified.

[0056] Please continue to refer to Figure 2 and Figure 3 According to some embodiments of the present application, the receiving portion 120 may further include a first slidable member 123. The second connecting portion 1222 may include a first groove 12221, and the rotating member 1211 may include a second groove 12111. The first groove 12221 and the second groove 12111 may be arranged opposite to each other, and the first slidable member 123 may be clamped in the first groove 12221 and the second groove 12111.

[0057] The first slidable member 123 may be a ball bearing, a slider, or the like.

[0058] The first groove 12221 on the second connection part 1222 may be provided on a side of the second connection part 1222 facing the rotating member 1211. The second groove 12111 on the rotating member 1211 may be provided on a side of the rotating member 1211 facing the second connection part 1222. The first groove 12221 and the second groove 12111 may face each other to clamp the first slidable member 123. The shapes of the first groove 12221 and the second groove 12111 may match the first slidable member 123, respectively.

[0059] In the above implementation process, the first groove 12221 and the second groove 12111 are respectively provided on the second connection part 1222 and the rotating member 1211, and the first slidable member 123 is clamped by the first groove 12221 and the second groove 12111. On the basis of realizing the rotatable connection between the rotating member 1211 and the base 122 through this ball bearing-like structure, the resistance between the rotating member 1211 and the second connection part 1222 is also reduced, so that the target object 20 can be relatively rotated with the housing 110 more smoothly according to the force applied to the target object 20 when it is received in the receiving device 100. In addition, the probability of the target object 20 being scratched is further reduced.

[0060] Please continue to refer to Figure 3 According to some embodiments of the present application, the device may further include a connector 130. A through hole 140 that is interconnected may be provided at the connection between the first connector 1221 and the housing 110. The connector 130 may be configured to be inserted into the through hole 140 that is interconnected to fix the first connector 1221 and the housing 110.

[0061] The first connecting member 130 may be a bolt, a connecting pin, or the like.

[0062] The connection between the first connection portion 1221 connected to the housing 110 and the housing 110 can be achieved by the above-mentioned bolts or connecting pins.

[0063] In the above implementation process, the first connecting member 130 is inserted into the through hole 140 that is interconnected at the connection between the first connecting portion 1221 and the housing 110, thereby realizing a detachable connection between the base 122 and the housing 110. This facilitates the individual maintenance and replacement of the components of the receiving device 100, thereby reducing the maintenance cost of the receiving device 100.

[0064] Please combine Figure 2 Reference Figure 4 , Figure 4 1 is a second cross-sectional view of the receiving device 100 provided in some embodiments of the present application. According to some embodiments of the present application, the movable connection portion 121 may include a rotating assembly 1212. The first rotating connection end 12121 of the rotating assembly 1212 may be connected to the first end 111 of the housing 110. The second rotating connection end 12122 of the rotating assembly 1212 may be configured to receive the target object 20 and, based on the force applied to the target object 20, rotate relative to the first rotating connection end 12121.

[0065] In the embodiment of the present application, the receiving portion 120 may only include the movable connecting portion 121, that is, the entire receiving portion 120 is the movable connecting portion 121. The movable connecting portion 121 may be a rotating component 1212, such as a rotating bearing.

[0066] In the rotating assembly 1212, the first rotating connection end 12121 and the second rotating connection end 12122 can rotate relative to each other. That is, the first rotating connection end 12121 and the second rotating connection end 12122 are rotatably connected. The specific rotatable connection method can be achieved by a rotating shaft provided on the first rotating connection end 12121 or the second rotating connection end 12122; or it can be achieved by providing a ball bearing-like structure between the first rotating connection end 12121 and the second rotating connection end 12122.

[0067] When the first rotating connection end 12121 is connected to the first end 111 of the shell 110, the second rotating connection end 12122 is used to receive the target object 20, so that the target object 20 can rotate relative to the shell 110 according to the force applied to the target object 20 when received in the receiving device 100.

[0068] The connection between the first rotating connection end 12121 and the first end 111 of the housing 110 may be integrally formed, welded, or detachably connected, etc. The specific detachable connection method may be connected by inserting bolts or connecting pins as described above.

[0069] In the above implementation process, the first rotating connection end 12121 and the second rotating connection end 12122 are rotatably connected, and the first rotating connection end 12121 is connected to the first end 111 of the housing 110, and then the second rotating connection end 12122 receives the target object 20. Similarly, a simple structure is used to achieve that when the target object 20 is received in the receiving device 100, it can rotate relative to the housing 110 according to the force applied to the target object 20. On the basis of reducing the probability of the target object 20 being scratched, the structure of the receiving device 100 is simplified.

[0070] Please continue to refer to Figure 2 and Figure 4 According to some embodiments of the present application, the rotating assembly 1212 may further include a second slidable member 12125. The first rotating connection end 12121 may include a third groove 12123, and the second rotating connection end 12122 may include a fourth groove 12124. The third groove 12123 and the fourth groove 12124 may be arranged opposite to each other, and the second slidable member 12125 may be clamped in the third groove 12123 and the fourth groove 12124.

[0071] The second slidable member 12125 can also be a ball bearing or a slider, etc.

[0072] The third groove 12123 on the first rotating connection end 12121 may be provided on a side of the first rotating connection end 12121 facing the second rotating connection end 12122. The fourth groove 12124 on the second rotating connection end 12122 may be provided on a side of the second rotating connection end 12122 facing the first rotating connection end 12121. The third groove 12123 and the fourth groove 12124 may face each other to clamp the second slidable member 12125. The shapes of the third groove 12123 and the fourth groove 12124 may match the second slidable member 12125, respectively.

[0073] In the above implementation process, the third groove 12123 and the fourth groove 12124 are respectively provided on the first rotating connection end 12121 and the second rotating connection end 12122, and the second slidable member 12125 is clamped by the third groove 12123 and the fourth groove 12124. On the basis of realizing the rotatable connection between the first rotating connection end 12121 and the second rotating connection end 12122 through this ball bearing-like structure, the resistance between the first rotating connection end 12121 and the second rotating connection end 12122 is also reduced, so that the target object 20 can be relatively rotated with the housing 110 more smoothly according to the force applied to the target object 20 when it is received in the receiving device 100. Furthermore, the probability of the target object 20 being scratched is also further reduced.

[0074] Please refer to Figure 3 and Figure 4 According to some embodiments of the present application, the target object 20 may include a cylindrical object, and the housing 110 may include a cylindrical housing 110 surrounding a cylindrical accommodation space. The radial dimension D2 of the opening 1121 may be greater than the radial dimension D1 of the accommodation space. That is, a circle of guide angles may be provided at the edge of the opening 1121 of the housing 110 to guide the target object 20 into the accommodation space. Among them, the radial direction may be perpendicular to the direction of the opening 1121. It is worth mentioning that the perpendicularity between the radial direction and the direction of the opening 1121 is not an absolute perpendicularity in theory, but the angle between the radial direction and the direction of the opening 1121 may be slightly greater than 90° or less than 90°. For example, one of the angles between the radial direction and the direction of the opening 1121 may be in the range of 80° to 100°, or in the range of 85° to 95°.

[0075] The cylindrical object may be a cylindrical electrode assembly, etc. Accordingly, the housing 110 and the accommodating space formed around it may also be cylindrical in shape matching the shape of the cylindrical object.

[0076] In the above implementation process, the radial size of the opening 1121 can be larger than the radial size of the accommodating space, thereby guiding the target object 20 into the accommodating space, so that the target object 20 can enter the accommodating space more easily.

[0077] Please continue to refer to Figure 3 and Figure 4 According to some embodiments of the present application, a slot 112 may be provided at the end of the housing 110 away from the opening 1121 and the accommodating space. The slot 112 may be configured to engage a transport portion of the transport device. The transport portion may be used to transport the receiving device 100.

[0078] As an example, the slot 112 may be disposed between the first end 111 and the second end 112 , and surround the outer surface of the housing 110 with the rotation axis of the target object 20 rotating as an axis.

[0079] The transport device may be a robot, and the transport portion may be a portion of the robot that is in direct contact with the transported object.

[0080] In the above implementation process, the housing 110 is provided with a card slot 112 for carding with the transport portion of the transport device, thereby reducing the probability of the receiving device 100 slipping off the transport portion during being transported by the transport device.

[0081] According to some embodiments of the present application, the target object 20 may include a cylindrical electrode assembly. The housing 110 may include a cylindrical housing 110 surrounding a cylindrical accommodation space.

[0082] In the above-mentioned implementation process, by using the receiving device 100 provided in each embodiment of the present application to receive the cylindrical battery cell, relative rotation between the cylindrical electrode assembly and the shell 110 is achieved, and then in the process of passing through a channel 200 such as a logistics line diversion port, the cylindrical electrode assembly can roll when contacting the edge of the channel 200, thereby reducing the probability of the cylindrical electrode assembly being scratched.

[0083] Please refer to Figure 5 , Figure 5 1 is a schematic diagram of the structure of the assembly line 10 provided in some embodiments of the present application. The assembly line 10 may include a channel 200 and a receiving device 100. The receiving device 100 may be configured to partially accommodate a target object 20 therein and may move on the assembly line 10. The channel 200 may include an edge of the channel 200. During the movement of the receiving device 100 on the assembly line 10, the edge of the channel 200 may be configured to contact the target object 20. The contact may provide a driving force for the relative rotation of the target object 20 and the receiving device 100.

[0084] The assembly line 10 may include a logistics line, and a channel 200 may be provided on the logistics line. The channel 200 may have channel 200 edges on both sides. The channel 200 edges may prevent materials on the logistics line from falling out of the logistics line during the movement process; or, may guide the materials to move in a specific direction.

[0085] Based on the above examples, it should be understood that the contact between the target object 20 and the edge of the channel 200 does not necessarily mean that the target object 20 and the edge of the channel 200 are always and continuously in contact during the entire process in which the receiving device 100 guiding the target object 20 at the edge of the channel 200 moves in a specific direction. Instead, it may be that the target object 20 and the edge of the channel 200 are not in contact at a certain stage or several stages during the process.

[0086] It can be seen that the channel 200 can also play a role in diverting the receiving device 100 that receives the target object 20 from the receiving device 100 that does not receive the target object 20 .

[0087] However, in the process of the edge of the channel 200 guiding the target object 20 to move in a specific direction, sliding friction usually occurs between the edge of the channel 200 and the target object 20, which may cause scratches on the target object 20. In view of this, in the assembly line 10 provided in the embodiment of the present application, the target object 20 can rotate relative to the receiving device 100 during the movement by relying on the friction provided by the contact with the edge of the channel 200. In addition, the sliding friction between the target object 20 and the edge of the channel 200 is converted into rolling friction, reducing the probability of the target object 20 being scratched.

[0088] In summary, the receiving device 100 and the assembly line 10 provided by each embodiment of the present application, by providing the movable connecting portion 121 at the bottom of the receiving device 100, realizes that when the target object 20 is received in the receiving device 100, it rotates relative to the housing 110 according to the force of the target object 20, thereby reducing the probability of the target object 20 being scratched. By providing a slidable member such as a ball or a slider in the receiving portion 120, the rotation of the movable connecting portion 121 is realized, and the rotation resistance is reduced, so that when the target object 20 is received in the receiving device 100, it can rotate relative to the housing 110 more smoothly according to the force of the target object 20. Furthermore, the probability of the target object 20 being scratched is further reduced. The design that the radial size of the opening 1121 can be larger than the radial size of the accommodation space plays a role in guiding the target object 20 into the accommodation space, so that the target object 20 can enter the accommodation space more easily.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
