Technical Field

[0001] The present application relates to the technical field of battery manufacturing, and in particular to a workpiece blocking device and a battery production system. Background Art

[0002] In the production process of batteries, batteries can be transported between different processes or stations via a conveyor belt. In some cases, it is necessary to stop the batteries being transported on the conveyor belt to position the batteries or arrange multiple batteries. Therefore, it is necessary to block the batteries. There is a need for further optimization of the battery blocking device in the related art. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems in the background technology. To this end, one object of the present application is to provide a workpiece blocking device and a battery production system.

[0004] An embodiment of the first aspect of the present application provides a workpiece blocking device, comprising: a mounting plate; a guide plate, mounted on the mounting plate and having a first guide groove; a guide rod, having a second guide groove; a first cam follower, mounted on the mounting plate and clamped in the second guide groove of the guide rod; a second cam follower, mounted on the first end of the guide rod and clamped in the first guide groove of the guide plate; a driver, mounted on the mounting plate, and a movable part of the driver is mechanically connected to the first end of the guide rod, for driving the guide rod to move between a first position and a second position, at least one of the movement of the first cam follower in the second guide groove and the movement of the second cam follower in the first guide groove defining the movement path of the guide rod; and a blocking rod, connected to the second end of the guide rod opposite to the first end, for blocking the workpiece.

[0005] In the technical solution of the embodiment of the present application, a guide plate, a guide rod, a first cam follower and a second cam follower are arranged in the workpiece blocking device, and the reciprocating motion of the driver is converted into the rotational motion of the blocking rod through the movement of the first cam follower in the second guide groove of the guide rod and the movement of the second cam follower in the first guide groove of the guide plate. The structure is more reliable, can improve the mechanical stability of the workpiece blocking device, the positioning accuracy of the workpiece, and can extend the service life of the driver.

[0006] In some embodiments, the driver includes a driving cylinder, and the movable part of the driver includes a piston rod, and the workpiece blocking device also includes a buffer, the housing of the buffer is connected to the piston rod, and the buffer rod of the buffer that can move relative to the housing is arranged toward the mounting plate to contact the mounting plate when the piston rod is retracted toward the cylinder body of the driving cylinder, thereby providing buffering for the driving cylinder. Thus, in the case where the piston rod of the driving cylinder is retracted toward the cylinder body, when the piston rod is about to reach its maximum retraction stroke, the buffer rod of the buffer can gradually abut the mounting plate to provide buffering for the driving cylinder, thereby protecting the driving cylinder from severe impact, thereby further improving the service life of the driving cylinder.

[0007] In some embodiments, the workpiece blocking device further comprises a driving rod, and the movable part of the driver is connected to the first end of the guide rod via the driving rod. Thus, by adding the driving rod to connect the movable part of the driver and the guide rod, a compact arrangement of the components can be achieved in a limited space.

[0008] In some embodiments, the movable part of the driver has a threaded hole, the driving rod has a through hole, and the workpiece blocking device further includes a shoulder screw, which passes through the through hole and is connected to the threaded hole, so as to connect the driving rod to the movable part of the driver in a shaky manner. Thus, a flexible connection is provided between the driving rod and the movable part of the driver, which not only avoids the rigid connection from damaging the driver to further improve its life, but also allows a certain assembly error.

[0009] In some embodiments, the guide plate includes a pair of guide plates disposed opposite to each other, and the guide rod includes a pair of guide rods disposed opposite to each other between the pair of guide plates, each guide rod in the pair of guide rods corresponds to a corresponding one of the guide plates, and the workpiece blocking device further includes a connecting shaft, which connects the driving rod to the pair of guide rods. Thus, by further providing the connecting shaft, the compact arrangement of the components can be further achieved in a limited space.

[0010] In some embodiments, the dimensions of the first guide groove and the second guide groove are configured such that: when the guide rod is located at the first position, the first cam follower is located at one end of the second guide groove, and the second cam follower is located at one end of the first guide groove; and when the guide rod is located at the second position, the first cam follower is located at the other end of the second guide groove, and the second cam follower is located at the other end of the first guide groove. Thus, the first position and the second position of the guide rod are defined by the two ends of each of the first guide groove and the second guide groove, and the structure is relatively simple.

[0011] In some embodiments, when the guide rod is located at the second position, a line between the second cam follower located at the other end of the first guide slot and the first cam follower mounted on the mounting plate is perpendicular to the top surface of the mounting plate, thereby making the position where the workpiece blocking device blocks the workpiece more accurate.

[0012] In some embodiments, when the guide rod is at the first position, the movable portion of the driver extends in a direction away from the body of the driver, thereby saving space on one side of the blocking rod, thereby providing enough space for the workpiece to pass through on this side and preventing the workpiece from being blocked by the extended movable portion.

[0013] In some embodiments, the workpiece blocking device further comprises a cam mounting seat, and the first cam follower is mounted on the mounting plate via the cam mounting seat. Thus, different positions of the first cam follower can be set via the cam mounting seat.

[0014] The second aspect of the present application provides a battery production system, comprising: a conveying device for conveying batteries; and a workpiece blocking device according to the first aspect of the present application, the workpiece blocking device being arranged above the conveying device for blocking the batteries conveyed on the conveying device. Thus, the positioning accuracy of the battery production system for the battery can be improved.

[0015] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are listed below.

[0028] The following embodiments of the technical solution of the present application will be described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0030] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may 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 article generally indicates that the associated objects before and after are in an "or" relationship.

[0033] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0034] In the description of the embodiments of the present application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the embodiments of the present application.

[0035] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0036] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0037] In the related art, the battery blocking device may have one or more rotating cylinders arranged above the battery conveyor belt, and the rotating cylinders may be located at approximately the same height level as the battery being conveyed. The rotating cylinder may have a blocking rod connected to the rotating shaft, and when it is necessary to block the movement of the battery, the rotating cylinder may rotate the blocking rod to a certain angle (for example, rotate it to be parallel to the surface of the conveyor belt), so that the blocking rod is placed in front of the running direction of the battery, thereby blocking the movement of the battery. When it is necessary to release the battery, the rotating cylinder may rotate the blocking rod to another angle (for example, rotate it to be perpendicular to the surface of the conveyor belt), so that the blocking rod is moved away from the running direction of the battery, thereby releasing the battery.

[0038] However, due to the need to frequently block and release the battery, the rotating shaft of the rotating cylinder of the battery blocking device in the related art needs to be frequently rotated from one angle to another, and needs to be locked at a certain angle for a long time to maintain the state of the blocking rod blocking the battery or maintaining the state of the blocking rod releasing the battery. The locking of the rotating shaft rotation angle is usually achieved by using a guide groove. For example, the guide groove can limit a certain angle range so that the rotating shaft or the blocking rod can only rotate within the angle range. Accordingly, the two ends of the angle range limited by the guide groove can correspond to the state of the blocking rod blocking the battery and the state of the blocking rod releasing the battery. With the increasing number of operations, not only will the wear of the guide groove cause changes in the blocking position, thereby causing inaccurate battery positioning, but it will also make the frequently rotating cylinder prone to jamming or insufficient service life.

[0039] Based on the above considerations, in order to improve the mechanical stability and positioning accuracy of the battery blocking device and extend its service life, one object of the present application is to provide a workpiece blocking device and a battery production system. By arranging a guide plate, a guide rod, a first cam follower and a second cam follower in the workpiece blocking device, and by the movement of the first cam follower in the second guide groove of the guide rod and the movement of the second cam follower in the first guide groove of the guide plate, the reciprocating motion of the driver is converted into the rotational motion of the blocking rod, the structure is more reliable, the mechanical stability of the workpiece blocking device and the positioning accuracy of the workpiece can be improved, and the service life of the driver can be extended.

[0040] The workpiece blocking device disclosed in the embodiment of the present application is not limited to being used for blocking batteries during the battery production process, but can also be used for blocking other workpieces.

[0042] See also Figures 1 to 8 , the workpiece blocking device 100 comprises:

[0043] Mounting plate 110;

[0044] The guide plate 120 is mounted on the mounting plate 110 and has a first guide groove 121;

[0045] The guide rod 130 has a second guide groove 131;

[0046] A first cam follower 140 is mounted on the mounting plate 110 and is clamped in the second guide groove 131 of the guide rod 130;

[0047] The second cam follower 150 is mounted on the first end of the guide rod 130 and is clamped in the first guide groove 121 of the guide plate 120;

[0048] a driver 160 mounted on the mounting plate 110, and a movable portion 161 of the driver 160 is mechanically connected to the first end of the guide rod 130, for driving the guide rod 130 to move between the first position and the second position, at least one of the movement of the first cam follower 140 in the second guide groove 131 and the movement of the second cam follower 150 in the first guide groove 121 defining a movement path of the guide rod 130; and

[0049] The blocking rod 170 is connected to the second end portion of the guide rod 130 opposite to the first end portion, and is used to block the workpiece.

[0050] In an example, the mounting plate 110 may have a plurality of holes, such as a plurality of screw holes, for connection with other components.

[0051] The guide plate 120 can be mounted on the mounting plate 110 by screws, for example. Figure 1 or Figure 4 As shown, the guide plate 120 can be vertically mounted on the mounting plate 110. Figure 7 As shown, the first guide groove 121 on the guide plate 120 may be a through groove (ie, a through groove passing through the entire thickness of the guide plate 120 ) or may not be a through groove.

[0052] like Figure 8 As shown, the second guide groove 131 on the guide rod 130 may be a through groove (ie, a through groove passing through the entire thickness of the guide rod 130 ) or may not be a through groove.

[0053] The first cam follower 140 and the second cam follower 150 may be, for example, cam bearing followers (or cam roller bearings). The cam follower may include a mounting shaft, an outer ring, an inner ring, and needle rollers (or balls), wherein the inner ring is fixed on the mounting shaft, the outer ring is sleeved on the axial outer side of the inner ring, and a plurality of needle rollers are arranged between the inner ring and the outer ring to achieve relative rotation between the inner ring and the outer ring.

[0054] The mounting shaft of the first cam follower 140 may be mounted on the mounting plate 110. And the outer ring (the portion rotatable relative to the mounting shaft) of the first cam follower 140 may be snap-fitted into the second guide groove 131 of the guide rod 130. In an example, a lubricant may be applied between the first cam follower 140 and the second guide groove 131 to reduce friction therebetween.

[0055] The mounting shaft of the second cam follower 150 may be mounted on the first end of the guide rod 130. And the outer ring (the portion rotatable relative to the mounting shaft) of the second cam follower 150 may be snap-fitted into the first guide groove 121 of the guide plate 120. In an example, a lubricant may be applied between the second cam follower 150 and the second guide groove 131 to reduce friction therebetween.

[0056] The driver 160 can be mounted on the mounting plate 110 by screws. The driver 160 can be, for example, a driver capable of reciprocating motion. In an example, the driver 160 can be a motor or a cylinder, and a housing of the driver 160 (e.g., a cylinder body of a cylinder) can be fixed to the mounting plate 110. The movable portion 161 of the driver 160 (e.g., a piston rod of a cylinder or a shaft of a linear motor) can be mechanically connected to the first end of the guide rod 130 with or without a connector. For example, the movable portion 161 of the driver 160 can be mechanically connected to the first end of the guide rod 130 indirectly through a plurality of connectors.

[0057] Continue to refer Figure 1 and Figure 4 ,exist Figure 1 In the state where the guide rod 130 is located in the first position, it can be seen that the guide rod 130 lifts the blocking rod 170, and at this time the blocking rod 170 can, for example, release the workpiece; Figure 4 In the state where the guide rod 130 is located at the second position, it can be seen that the guide rod 130 lowers the blocking rod 170, and the blocking rod 170 can block the workpiece, for example. The driver 160 drives the guide rod 130 to move between the first position and the second position.

[0058] The movement path of the guide rod 130 (in other words, the positions of the first position and the second position) can be defined by the movement of the first cam follower 140 in the second guide groove 131, or by the movement of the second cam follower 150 in the first guide groove 121, or the movement path of the guide rod 130 can be defined by both the movement of the first cam follower 140 in the second guide groove 131 and the movement of the second cam follower 150 in the first guide groove 121.

[0059] Therefore, by providing the guide plate 120, the guide rod 130, the first cam follower 140 and the second cam follower 150 in the workpiece blocking device 100, and by the movement of the first cam follower 140 in the second guide groove 131 of the guide rod 130, and the movement of the second cam follower 150 in the first guide groove 121 of the guide plate 120, the reciprocating motion of the driver 160 is converted into the rotational motion of the blocking rod 170, the structure is more reliable, the mechanical stability of the workpiece blocking device 100 and the positioning accuracy of the workpiece can be improved, and the service life of the driver 160 can be extended.

[0060] According to some embodiments of the present application, the driver 160 includes a driving cylinder, and the movable part 161 of the driver 160 includes a piston rod, and the reference Figure 3 , Figure 5 and Figure 6 The workpiece blocking device 100 may further include a buffer 180, a housing 181 of which is connected to a piston rod, and a buffer rod 182 of which is movable relative to the housing 181 and is arranged toward the mounting plate 110 so as to contact the mounting plate 110 when the piston rod (movable part 161) is retracted toward the cylinder body of the driving cylinder, thereby providing buffering for the driving cylinder.

[0061] In an example, the driving cylinder may be a reciprocating cylinder, a piston rod of which can extend from a cylinder body of the driving cylinder and can be retracted into the cylinder body of the driving cylinder.

[0062] The buffer 180 may be a shock absorber, and the buffer 180 may have a spring and a pressure oil chamber disposed in the housing 181, and the buffer rod 182 may extend from the pressure oil chamber to the outside of the housing 181. When the buffer rod 182 of the buffer 180 is squeezed by force, it can play a buffering role under the pressure in the pressure oil chamber and the action of the spring. In the example, the initial extension length of the buffer rod 182, the pressure of the pressure oil chamber, and the elastic force of the spring can be adjusted so that the buffer 180 can adapt to different specifications of the workpiece blocking device 100.

[0063] Therefore, when the piston rod of the driving cylinder retracts into the cylinder body, when the piston rod is about to reach its maximum retraction stroke, the buffer rod 182 of the buffer 180 can gradually abut the mounting plate 110 to provide buffering for the driving cylinder, thereby protecting the driving cylinder from severe impact, thereby further improving the service life of the driving cylinder.

[0064] According to some embodiments of the present application, the workpiece blocking device 100 may further include a driving rod 190 , and the movable portion 161 of the driver 160 is connected to the first end of the guide rod 130 via the driving rod 190 .

[0065] One end of the driving rod 190 may be connected to the movable portion 161 of the driver 160 , and the other end of the driving rod 190 may be directly or indirectly mechanically connected to the first end portion of the guide rod 130 .

[0066] Thus, by adding the driving rod 190 to connect the movable portion 161 of the driver 160 and the guide rod 130 , a compact arrangement of the components can be achieved in a limited space.

[0067] According to some embodiments of the present application, Figure 3 As shown, the movable part 161 of the driver 160 can have a threaded hole 162, the drive rod 190 can have a through hole 191, and the workpiece blocking device 100 can also include a shoulder screw 192, which passes through the through hole 191 and is connected to the threaded hole 162, thereby connecting the drive rod 190 to the movable part 161 of the driver 160 in a swingable manner.

[0068] The shoulder screw 192 may also be called a shoulder screw or a shoulder screw, and its lower half may have threads, while the upper half may not have threads. The threaded lower half of the shoulder screw 192 may be threadedly connected to the threaded hole 162 of the movable part 161 (e.g., one end of the piston rod) of the driver 160. The unthreaded upper half of the shoulder screw 192 may be inserted into the through hole 191 of the drive rod 190 and is clearance-matched with the through hole 191 (in other words, the unthreaded upper half of the shoulder screw 192 may have a certain distance from the inner wall of the through hole 191), thereby allowing the drive rod 190 and the shoulder screw 192 to shake.

[0069] Thus, a flexible connection is provided between the driving rod 190 and the movable portion 161 of the driver 160, which not only avoids the rigid connection from damaging the driver 160 to further increase its life span, but also allows a certain assembly error.

[0070] According to some embodiments of the present application, continue to refer to Figure 1 The guide plate 120 may include a pair of guide plates arranged opposite to each other, and the guide rod 130 may include a pair of guide rods arranged opposite to each other between the pair of guide plates, each guide rod in the pair of guide rods corresponds to a corresponding guide plate, and the workpiece blocking device 100 may also include a connecting shaft 193, which connects the driving rod 190 to the pair of guide rods.

[0071] In an example, a pair of guide rods may be disposed against respective inner walls of a pair of guide plates, and the driver 160 may be disposed between the pair of guide rods.

[0072] In an example, a portion of the driving rod 190 connected to the connecting shaft 193 may be provided with a through hole, and the connecting shaft 193 may be rotatably disposed in the through hole of the driving rod 190 . In addition, the connecting shaft 193 may be rotatably connected to the pair of guide rods 130 .

[0073] Therefore, by further providing the connecting shaft 193, it is possible to further achieve a compact arrangement of the components in a limited space.

[0074] According to some embodiments of the present application, the dimensions of the first guide groove 121 and the second guide groove 131 are configured as follows:

[0075] When the guide rod 130 is located at the first position, the first cam follower 140 is located at one end of the second guide groove 131, and the second cam follower 150 is located at one end of the first guide groove 121; and

[0076] When the guide rod 130 is located at the second position, the first cam follower 140 is located at the other end of the second guide groove 131 , and the second cam follower 150 is located at the other end of the first guide groove 121 .

[0077] like Figure 1 As shown, the guide rod 130 is located at the first position, at which time the first cam follower 140 is located at the end of the second guide groove 131 close to the left side, and the second cam follower 150 is located at the end of the first guide groove 121 close to the right side. Figure 4 As shown, the guide rod 130 is located at the second position, at which time the first cam follower 140 is located at the end of the second guide slot 131 close to the right side, and the second cam follower 150 is located at the end of the first guide slot 121 close to the left side.

[0078] Therefore, the first position and the second position of the guide rod 130 are defined by the two ends of the first guide groove 121 and the second guide groove 131 , respectively, and the structure is relatively simple.

[0079] According to some embodiments of the present application, when the guide rod 130 is at the second position, the line between the second cam follower 150 located at the other end of the first guide groove 121 and the first cam follower 140 installed on the mounting plate 110 is perpendicular to the top surface of the mounting plate 110.

[0080] Continue to refer Figure 4 and Figure 6 When the guide rod 130 is located at the second position, the line between the second cam follower 150 and the first cam follower 140 is perpendicular to the top surface of the mounting plate 110 , so that the guide rod 130 is perpendicular to the top surface of the mounting plate 110 .

[0081] As a result, the position where the workpiece blocking device 100 blocks the workpiece is more accurate.

[0082] According to some embodiments of the present application, when the guide rod 130 is located at the first position, the movable portion 161 of the driver 160 extends in a direction away from the body of the driver 160 .

[0083] Continue to refer Figure 1 and Figure 3 , when the guide rod 130 is located at the first position, it is equivalent to Figure 4 and Figure 6 In the illustrated embodiment, the movable portion 161 projects in a direction away from the body of the driver 160 .
