[0002] With the rapid development of new energy technologies, the demand for new energy products such as battery devices and energy storage devices continues to increase, which not only puts higher requirements on the production efficiency of these new energy products, but also puts higher requirements on the miniaturization of equipment to reduce the footprint. Summary of the invention

[0003] The embodiments of the present application provide a conveyor line, a material conveying method and a battery production line, which can improve conveying efficiency and reduce floor space.

[0005] Multiple circulating conveyor lines are formed by the cutting device and different conveyor line bodies. The multiple circulating conveyor lines can transport the loads (such as clamps) on their respective circulating conveyor lines to various workstations on the conveying path, and realize parallel process operation of each workstation while meeting the technological requirements of different processes, thereby speeding up the production cycle and improving production efficiency; and the use of the cutting device in multiple circulating conveyor lines can make the conveyor line as a whole more compact, thereby reducing the footprint.

[0006] In some embodiments, the multiple conveyor line bodies include a first conveyor line body and a second conveyor line body adjacent to each other along a first direction; the cutting device is arranged between the first conveyor line body and the second conveyor line body; wherein the cutting drive member is configured to drive the cutting conveyor line body to reciprocate along a second direction and alternately dock with the first conveyor line body and the second conveyor line body, so that the cutting device and the first conveyor line body constitute a first circulating conveyor line, and the cutting device and the second conveyor line body constitute a second circulating conveyor line, and the second direction intersects with the first direction.

[0007] By setting the cutting device between the first conveying line body and the second conveying line body, the cutting driving member drives the cutting conveying line body to move back and forth along the second direction and alternately dock with the first conveying line body and the second conveying line body, thereby forming a first circulating conveying line and a second circulating conveying line. Each circulating conveying line shares the cutting device, which improves the conveying efficiency and can reduce the occupied site space.

[0008] In some embodiments, the first conveying line body includes a first end and a second end opposite to each other along its conveying direction, and the second conveying line body includes a third end and a fourth end opposite to each other along its conveying direction; wherein the separation drive member is configured to drive the separation conveying line body to reciprocate along the second direction, alternately docking with the first end and the second end, and alternately docking with the third end and the fourth end.

DETAILED DESCRIPTION

[0045] 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 and completely 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, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0048] In the description of the embodiments of the present application, it should be noted that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, or the orientation or positional relationship commonly understood by those skilled in the art, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the 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. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0049] In the description of the embodiments of the present application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set" and "connection" 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 direct connection, or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] At present, from the perspective of market development, the application of new energy technologies is becoming more and more extensive. Taking batteries as an example, batteries are widely used in electric vehicles such as electric bicycles, electric motorcycles, electric vehicles, as well as electric tools, drones, energy storage equipment and other fields. With the continuous expansion of battery application areas, the market demand is also constantly expanding. Therefore, higher requirements are placed on the production efficiency of batteries, and higher requirements are also placed on the miniaturization of production equipment.

[0051] In the production and manufacturing process of batteries, often one assembly section requires multiple processes. At present, multiple processes are concentrated in one workstation, that is, multiple processes are completed in sequence at one workstation, resulting in that when the action of the previous process is completed, it is necessary to wait for the action of the last process to be completed before the next round of process operations can be carried out. As a result, there is a problem of low production efficiency.

[0052] By splitting multiple processes in an assembly section, multiple processes are carried out in different workstations, and the materials to be processed are transported to each workstation through a circular conveyor line. This design enables each workstation to perform its own actions independently, thereby realizing the linkage and parallel operation of multiple processes, thereby speeding up the production rhythm and improving production efficiency.

[0053] In the case of multiple process splitting, different processes may have large process differences, and different fixtures are required in different processes, and the material postures may also be different in different processes. For example, in the assembly section where the top cover and the shell of the battery are welded, since the long side and short side of the top cover are in different positions, different fixtures are required to hold the battery for long side welding and short side welding to meet the requirements for different postures of the top cover during long side welding and short side welding.

[0054] The fixtures are transported separately through multiple circulating conveyor lines, and each fixture circulates on its own circulating conveyor line. Even if the posture of the battery needs to be changed in different processes, multi-process linkage and parallel operation can be achieved. In addition, sharing some areas in multiple circulating conveyor lines can simplify the conveyor line structure and make the overall structure more compact, thereby reducing the floor space.

[0055] Based on the above design concept, an embodiment of the present application provides a conveyor line, comprising: multiple conveyor line bodies for conveying loads; a cutting device, comprising a cutting conveyor line body and a cutting drive, the cutting drive is connected to the cutting conveyor line body, the cutting conveyor line body is used to receive the loads from each conveyor line body and convey the loads to the respective conveyor line bodies, wherein the cutting drive is configured to drive the cutting conveyor line body to move to dock with each conveyor line body, so that the cutting device and the multiple conveyor line bodies alternately form multiple circulating conveyor lines.

[0056] Multiple circulating conveyor lines are formed by alternating cutting devices and multiple conveyor line bodies. The multiple circulating conveyor lines can circulate the loads (such as clamps) on their respective circulating conveyor lines, thereby transporting the loads to various stations on the conveying path. As a result, the linkage and parallel operation between the stations can be achieved while meeting the process requirements of different processes, thereby speeding up the production rhythm and improving production efficiency. In addition, the multiple circulating conveyor lines have a shared area, which can make the conveyor line as a whole more compact, thereby reducing the footprint.

[0057] The conveyor line of the embodiment of the present application can be applied to various assembly sections in the production and manufacturing of batteries. It is particularly suitable for assembly sections with multiple processes linked to different postures of battery cells. Through multiple circulating conveyor lines, the loads on each are transported to each station, so that each station can independently perform its own actions, thereby realizing the linkage and parallel operation of multiple processes, thereby speeding up the production rhythm and improving production efficiency. In the following description, the assembly section where the top cover and the shell of the battery are welded is used as an example, but the present application is not limited to this.

[0058] Refer to the following Figures 1 to 9 , the conveyor line 100 of the embodiment of the present application is described in detail.

[0059] The embodiment of the present application provides a conveyor line 100, comprising: a plurality of conveyor line bodies 10 for conveying loads; a cutting device 20, comprising a cutting conveyor line body 21 and a cutting drive 22, wherein the cutting drive 22 is connected to the cutting conveyor line body 21, and the cutting conveyor line body 21 is used to receive the loads from each conveyor line body 10 and convey the loads to each conveyor line body 10, wherein the cutting drive 22 is configured to drive the cutting conveyor line body 21 to move to dock with each conveyor line body, so that the cutting device 20 and the plurality of conveyor line bodies 10 alternately form a plurality of circulating conveyor lines.

[0060] The conveyor line 10 is used to convey the load along the conveying direction. The load can be a fixture or a material. In other words, the conveyor line 10 can directly convey the material or convey the material through a fixture. The number of conveyor lines 10 can be two, three or more.

[0061] The separation device 20 and the plurality of conveyor line bodies 10 alternately constitute a plurality of circulating conveyor lines. Specifically, the separation drive 22 drives the separation conveyor line body 21 to move to a receiving position of a certain conveyor line body 10 and dock with the conveyor line body 10. At the receiving position, the separation conveyor line body 21 can receive the load conveyed by the conveyor line body 10 docked with it, and can move to the return position with the load under the drive of the separation drive 22 and dock with the conveyor line body 10. At the return position, the separation conveyor line body 21 returns the received load to the docked conveyor line body 10, so that the separation device 20 and the conveyor line body 10 constitute a circulating conveyor line, that is, the separation device 20 is a part of the circulating conveyor line.

[0062] The separation drive 22 drives the separation conveyor line 21 to move to the receiving position of another conveyor line 10 and dock with the other conveyor line 10. At the receiving position, the separation conveyor line 21 can receive the load transported by the other conveyor line 10 docked with it, and can move to the return position with the load under the drive of the separation drive 22 and dock with the other conveyor line 10. At the return position, the separation conveyor line 21 returns the received load to the other conveyor line 10, so that the separation device 20 and the other conveyor line 10 constitute another circulating conveyor line, that is, the separation device 20 is a part of the other circulating conveyor line. Thus, the separation device 20 alternately forms multiple circulating conveyor lines with each conveyor line 10.

[0063] Thus, the separation drive 22 can drive the separation conveying line 21 to move to dock with each conveying line 10, and the separation conveying line 21 can receive the load from each conveying line 10 and transport the load back to the respective conveying line 10.

[0064] As an example, multiple clamps can be circulated on each circulating conveyor line, and the clamps circulated on each circulating conveyor line can be the same or different. In the case of different clamps, different clamps are convenient for clamping batteries in different postures to meet the process requirements of multiple processes for battery posture.

[0065] A plurality of circulating conveyor lines are formed by the cutting device 20 and different conveyor line bodies 10. The plurality of circulating conveyor lines can convey the loads (such as fixtures) on their respective circulating conveyor lines to each workstation on the conveying path, thereby realizing parallel process operation of each workstation while meeting the technological requirements of different processes, thereby speeding up the production cycle and improving production efficiency; and, the use of the cutting device in a plurality of circulating conveyor lines can make the conveyor line 100 more compact as a whole, thereby reducing the floor space occupied.

[0066] In some embodiments, reference Figure 1 and Figure 2The separation drive member 22 includes a first linear motor, and the first linear motor includes a first stator 221 and a first mover 222. The separation conveyor line body 21 includes a separation stator 201, and the separation stator 201 is fixed to the first mover 222; the conveyor line body 10 includes a second linear motor, and the second linear motor includes a second stator 101 and a second mover 102, and the second mover 102 is used to place the load.

[0067] The first mover 222 can drive the separation stator 201 to move back and forth under the drive of the electromagnetic force of the first stator 221, so as to dock with each conveying line body 10. In the docking state, the second mover 102 carrying the load (such as a clamp) of each conveying line body 10 is received by the drive of the electromagnetic force of the separation stator 201, or the second mover 102 carrying the load is transported back to the respective conveying line body 10. The path of the reciprocating movement of the separation stator 201 is a part of the conveying path of each circulating conveying line.

[0068] The second mover 102 is driven by the electromagnetic force of the second stator 101 to transport the load (e.g., a fixture) thereon. A plurality of second movers 102 may be provided, such as two, three, four, or more. In order to improve the stability during the transport process, the first mover 222 may be slidably provided on a first guide rail extending in its moving direction.

[0069] The conveyor line body 10, the separation drive member 22 and the separation conveyor line body 21 all use linear motors, and realize linear motion through electromagnetic force, which is convenient for each conveyor line body 10 to dock with the separation conveyor line body 21, and improves the reliability of the load when it circulates between the conveyor line body 10 and the separation conveyor line body 21. In addition, the reciprocating linear motion is realized by electromagnetic force, thereby facilitating the control of direction, and no intermediate conversion mechanism is required, which simplifies the conveyor line structure and reduces the occupied site area.

[0070] Of course, the conveyor line body 10 may also adopt other conveying mechanisms. For example, a conveyor belt mechanism, a conveyor roller mechanism, etc. The drive mode of the separation drive member 22 and the separation conveyor line body 21 may also adopt other mechanisms for realizing linear reciprocating movement. For example, the drive mode may be a rotating motor cooperating with a transmission component to realize the conversion of the rotational motion of the motor into linear motion, and the drive mode may also be realized by a cylinder or a hydraulic cylinder, etc.

[0071] In some embodiments, reference Figure 3, multiple conveyor line bodies 10 include a first conveyor line body 11 and a second conveyor line body 12 adjacent to each other along a first direction X; a cutting device 20 is arranged between the first conveyor line body 11 and the second conveyor line body 12; wherein, a cutting drive member 22 is configured to drive the cutting conveyor line body 21 to reciprocate along a second direction Y and alternately dock with the first conveyor line body 11 and the second conveyor line body 12, so that the cutting device 20 and the first conveyor line body 11 constitute a first circulating conveyor line 10a, and the cutting device 20 and the second conveyor line body 12 constitute a second circulating conveyor line 10b, and the second direction Y intersects with the first direction X.

[0072] The separation conveying line body 21 can be butted against the end or the middle of the first conveying line body 11. The separation conveying line body 21 can be butted against the end or the middle of the second conveying line body 12.

[0073] When the separation conveyor line 21 moves along the second direction Y to dock with the first conveyor line 11 under the drive of the separation drive 22, it can receive the load transported by the first conveyor line 11, or transport the load back to the first conveyor line 11, so that the load on the first conveyor line 11 circulates on the first circulating conveyor line 10a.

[0074] When the separation conveyor line 21 moves along the second direction Y to dock with the second conveyor line 12 under the drive of the separation drive 22, it can receive the load transported by the second conveyor line 12, or transport the load back to the second conveyor line 12, so that the load on the second conveyor line 12 circulates on the second circulating conveyor line 10b.

[0075] By setting the cutting device 20 between the first conveying line body 11 and the second conveying line body 12, the cutting driving member 22 drives the cutting conveying line body 21 to move back and forth along the second direction Y and alternately dock with the first conveying line body 11 and the second conveying line body 12, thereby forming a first circulating conveying line 10a and a second circulating conveying line 10b. Each circulating conveying line shares the cutting device 20, which improves the conveying efficiency and can reduce the occupied site space.

[0076] In some embodiments, reference Figure 3 The first conveyor line body 11 includes a first end 11a and a second end 11b opposite to each other along its conveying direction 11S (the direction indicated by the dotted line with an arrow in the figure), and the second conveyor line body 12 includes a third end 12a and a fourth end 12b opposite to each other along its conveying direction 12S (the direction indicated by the dotted line with an arrow in the figure); wherein the separation drive member 22 is configured to drive the separation conveyor line body 21 to reciprocate along the second direction Y, alternately docking with the first end 11a and the second end 11b, and alternately docking with the third end 12a and the fourth end 12b.

[0077] As an example, the separation conveyor line 21 is driven by the separation driving member 22 to move along the second direction Y close to the first end 11a until it docks with the first end 11a of the first conveyor line 11, and receives the load transported from the first conveyor line 11. The separation conveyor line 21 is driven by the separation driving member 22 to move along the second direction Y away from the first end 11a until it docks with the second end 11b of the first conveyor line 11, and transports the load back to the first conveyor line 11, so that the separation device 20 and the first conveyor line 11 form a first circulating conveyor line 10a.

[0078] When the separation conveyor line body 21 moves along the second direction Y close to the third end 12a under the drive of the separation driving member 22 until it docks with the third end 12a of the second conveyor line body 12, it receives the load transported from the second conveyor line body 12. When the separation conveyor line body 21 moves along the second direction Y away from the third end 12a under the drive of the separation driving member 22 until it docks with the fourth end 12b of the second conveyor line body 12, it transports the load back to the second conveyor line body 12, so that the separation device 20 and the second conveyor line body 12 form a second circulating conveyor line 10b.

[0079] The cut-off conveyor line body 21 is alternately docked with both ends (the first end 11a and the second end 11b) of the first conveyor line body 11, and receives and transports the load of the first conveyor line body 11 at both ends, and the cut-off conveyor line body 21 is alternately docked with both ends (the third end 12a and the fourth end 12b) of the second conveyor line body 12, and receives and transports the load of the second conveyor line body 12 at both ends, thereby forming a first circulating conveyor line 10a and a second circulating conveyor line 10b, making it easier and more reliable to dock the cut-off conveyor line body 21 with the first conveyor line body 11 and the second conveyor line body 12, and the overall structure is more compact.

[0080] In some embodiments, the separation drive 22 is configured to drive the separation conveyor line 21 to reciprocate between a first position W1 and a second position W2 along a second direction Y; wherein, in the first position W1, the separation conveyor line 21 is respectively docked with the first end 11a and the third end 12a, and in the second position W2, the separation conveyor line 21 is respectively docked with the second end 11b and the fourth end 12b.

[0081] The cut-off conveyor line 21 can receive the load conveyed by the first conveyor line 11 at one of the first position W1 and the second position W2 , and convey the load back to the first conveyor line 11 at the other of the first position W1 and the second position W2 .

[0082] The cut-off conveyor line 21 can also receive the load conveyed by the second conveyor line 12 at one of the first position W1 and the second position W2 , and convey the load back to the second conveyor line 12 at the other of the first position W1 and the second position W2 .

[0083] Therefore, by reciprocating the cutting conveyor line body 21 between the first position W1 and the second position W2, the cutting device 20 and the first conveyor line body 11 and the second conveyor line body 12 alternately form the first circulating conveyor line 10a and the second circulating conveyor line 10b, and the cutting conveyor line body 21 can receive the loads of different circulating conveyor lines at the same position or transport the loads back to different circulating conveyor lines. In this way, the cutting conveyor line body 21 can serve as the conveying path of each circulating conveyor line during the reciprocating switching movement between the first position W1 and the second position W2. Therefore, the production rhythm can be accelerated, the production efficiency can be improved, and the conveyor line 100 is more compact and the floor space is reduced.

[0084] In some embodiments, at the first position W1, the detached conveyor line 21 receives a first carrier transported from the first conveyor line 11, and transports the first carrier to the second position W2 under the drive of the detached driving member 22. At the second position W2, the detached conveyor line 21 transports the first carrier to the first conveyor line 11; at the second position W2, the detached conveyor line 21 receives a second carrier from the second conveyor line 12, and transports the second carrier to the first position W1 under the drive of the detached driving member 22. At the first position W1, the detached conveyor line 21 transports the second carrier to the second conveyor line 12.

[0085] At the first position W1, while the cutting conveyor line 21 is conveying the second load to the second conveyor line 12, that is, while the second load leaves the cutting conveyor line 21, the cutting conveyor line 21 receives the first load from the first conveyor line 11. At the second position W2, while the cutting conveyor line 21 is conveying the first load back to the first conveyor line 11, that is, while the first load leaves the cutting conveyor line 21, the cutting conveyor line 21 receives the second load from the second conveyor line 12.

[0086] As an example, see Figure 3 and Fig. 9 The first carrier may be a first clamp C1, and the second carrier may be a second clamp C2. The first clamp C1 is used to clamp the narrow side of the battery E, thereby meeting the welding process requirements of the long side of the top cover. The second clamp C2 is used to clamp the large side of the battery E, thereby meeting the welding process requirements of the short side of the top cover.

[0087] Specifically, the loading robot 1 places the battery E to be processed on the first clamp C1 of the first conveyor line body 11, and the first conveyor line body 11 conveys the battery E to be processed to the long side welding position of the top cover for welding the long side of the top cover. After welding is completed, the first conveyor line body 11 conveys the first clamp C1 carrying the battery E with the long side of the top cover welded to the first end 11a, and the cutting conveyor line body 21 at the first position W1 receives the first clamp C1. The position change robot 2 picks up the battery E with the long side of the top cover welded and places it on the second clamp C2 of the second conveyor line body 12. At this time, the posture of the battery E carried by the second clamp C2 changes, and the second conveyor line body 12 conveys the battery E on the second clamp C2 to the short side welding position of the top cover for welding the short side of the top cover. After welding is completed, the second conveyor line body 12 conveys the battery E with both the long and short sides of the top cover welded to the unloading station, and unloads it through the unloading robot 3.

[0088] Driven by the separation drive 22, the separation conveyor line 21 switches from the first position W1 to the second position W2 with the unloaded first clamp C1. At the second position W2, the separation conveyor line 21 transports the unloaded first clamp C1 back to the first conveyor line 11. The unloaded first clamp C1 continues to receive the unloaded battery E from the loading robot 1. At this time, the position on the separation conveyor line 21 is free to receive the unloaded second clamp C2 from the second conveyor line 12. Driven by the separation drive 22, the separation conveyor line 21 switches from the second position W2 to the first position W1 with the second clamp C2, and at the first position W1 transports the second fixture C2 back to the second conveyor line 12. At this time, the position on the cutting conveyor line 21 is free, and the first fixture C1 carrying the battery E with the long side of the top cover welded is received from the first conveyor line 11. The position change robot 2 picks up the battery E with the long side of the top cover welded and places it on the second fixture C2 of the second conveyor line 12. The second conveyor line 12 transports the battery E with the short side of the top cover to be welded on the second fixture C2 to the welding position of the short side of the top cover for welding the short side of the top cover. After welding, the second conveyor line 12 transports the battery E with both the long and short sides of the top cover welded to the unloading station, and unloads it through the unloading robot 3. This reciprocating cycle is repeated, and the first fixture C1 is circulated on the first circulation conveyor line 10a and the second fixture C2 is circulated on the second circulation conveyor line 10b through the shared cutting device 20, so as to continuously complete the welding of the long side and short side of the top cover.

[0089] Therefore, the cutting device 20 can carry the clamp during the reciprocating movement between the first position W1 and the second position W2, thereby speeding up the production cycle and improving production efficiency, and the conveyor line 100 is more compact and reduces the floor space.

[0090] In some embodiments, the separation drive 22 is configured to drive the separation conveyor line 21 to reciprocate between a first position W1, a second position W2 and a third position W3 along a second direction Y, and the second position W2 is located between the first position W1 and the third position W3; wherein, in the first position W1, the separation conveyor line 21 is docked with the first end 11a, and in the second position W2, the separation conveyor line 21 is docked with the second end 11b and the third end 12a respectively, and in the third position W3, the separation conveyor line 21 is docked with the fourth end 12b.

[0091] As an example, see Figure 4 and Fig. 9 , the separation conveyor line 21 can be provided with a, the feeding robot 1 places the battery E to be processed on the first clamp C1 of the first conveyor line 11, and the first conveyor line 11 conveys the battery E to be processed to the long side welding position of the top cover for welding the long side of the top cover. After the welding is completed, the first conveyor line 11 conveys the battery E with the long side of the top cover welded to the first end 11a, and the separation conveyor line 21 at the first position W1 receives the first clamp C1, and under the drive of the separation drive 22, the separation conveyor line 21 carries the first The clamp C1 switches from the first position W1 to the second position W2. At the second position W2, the position change robot 2 picks up the battery E with the long side of the top cover welded by the first clamp C1 and places it on the second clamp C2 of the second conveyor line 12. The second conveyor line 12 conveys the battery E with the short side of the top cover to be welded on the second clamp C2 to the welding position of the short side of the top cover for welding the short side of the top cover. After welding is completed, the second conveyor line 12 conveys the battery E with the long and short sides of the top cover welded to the unloading station for unloading by the unloading robot.

[0092] At the second position W2, the separation conveying line body 21 transports the unloaded first clamp C1 back to the first conveying line body 11, and under the drive of the separation driving member 22, the separation conveying line body 21 switches from the second position W2 to the third position W3. At the third position W3, the separation conveying line body 21 receives the unloaded second clamp C2 from the second conveying line body 12, and under the drive of the separation driving member 22, the separation conveying line body 21 switches from the third position W3 back to the second position W2 with the second clamp C2, and transports the second clamp C2 back to the second conveying line body 12 at the second position W2. Under the drive of the separation driving member 22, the separation conveying line body 21 switches from the second position W2 back to the first position W1, and at the first position W 1. The separation conveyor body 21 receives the battery E with the long side of the top cover welded from the first conveyor body 11. Under the drive of the separation drive 22, the separation conveyor body 21 switches from the first position W1 to the second position W2 with the first clamp C1. At the second position W2, the position change manipulator 2 picks up the battery E with the long side of the top cover welded by the first clamp C1 and places it on the second clamp C2 of the second conveyor body 12. The second conveyor body 12 transports the battery E with the short side of the top cover to be welded on the second clamp C2 to the welding position of the short side of the top cover for welding the short side of the top cover. After welding, the second conveyor body 12 transports the battery E with the long and short sides of the top cover welded to the unloading station, and unloads it through the unloading manipulator. In this way, the first clamp C1 circulates on the first circulation conveyor line 10a and the second clamp C2 circulates on the second circulation conveyor line 10b through the common separation device 20, thereby completing the welding of the long side and short side of the top cover uninterruptedly.

[0093] Therefore, by sharing the cutting device 20 between the two conveyor line bodies, the two conveyor line bodies are staggered and docked at the second position W2, which reduces the number of dockings, reduces the difficulty of docking, and can be flexibly arranged according to site needs.

[0094] In some embodiments, the separation conveyor line 21 includes a first separation conveyor line 211 and a second separation conveyor line 212; the separation drive 22 is configured to drive the first separation conveyor line 211 to reciprocate between a first position W1 and a second position W2 along a second direction Y and to drive the second separation conveyor line 212 to reciprocate between a second position W2 and a third position W3 along a second direction Y; wherein, when the first separation conveyor line 211 reaches the first position W1, the second separation conveyor line 212 reaches the second position W2, and when the first separation conveyor line 211 reaches the second position W2, the second separation conveyor line 212 reaches the third position W3; in the first position W1, the first separation conveyor line 211 is docked with the first end 11a, and in the second position W2, the first separation conveyor line 211 is docked with the second end 11b; in the second position W2, the second separation conveyor line 212 is docked with the third end 12a, and in the third position W3, the second separation conveyor line 212 is docked with the fourth end 12b.

[0095] The first cutting conveyor line 211 can receive the first clamp transported from the first conveyor line 11 at one of the first position W1 and the second position W2, and transport the first clamp back to the first conveyor line 11 at one of the first position W1 and the second position W2.

[0096] The second cutting conveyor line body 212 can receive the second clamp transported from the second conveyor line body 12 at one of the second position W2 and the third position W3, and transport the second clamp back to the second conveyor line body 12 at one of the second position W2 and the third position W3.

[0097] Two cutting conveyor line bodies (a first cutting conveyor line body 211 and a second cutting conveyor line body 212) are set through a cutting device 20, wherein when the first cutting conveyor line body 211 reaches the first position W1, the second cutting conveyor line body 212 reaches the second position W2, and when the first cutting conveyor line body 211 reaches the second position W2, the second cutting conveyor line body 212 reaches the third position W3, thereby, the two cutting conveyor line bodies move back and forth synchronously, thereby forming two circulating conveyor lines with the first conveyor line body 11 and the second conveyor line body 12 respectively, and the two circulating conveyor lines can be operated synchronously, further accelerating the production rhythm and improving production efficiency.

[0098] In some embodiments, at the second position W2, the first separation conveyor line 211 receives the first carrier transported from the first conveyor line 11, and transports the first carrier to the first position W1 under the drive of the separation drive 22. At the first position W1, the first separation conveyor line 211 transports the first carrier to the first conveyor line 11; at the third position W3, the second separation conveyor line 212 receives the second carrier transported from the second conveyor line 12, and transports the second carrier to the second position W2 under the drive of the separation drive 22. At the second position W2, the second separation conveyor line 212 transports the second carrier to the second conveyor line 12.

[0099] As an example, see Figure 4 and Fig. 9 , two separation conveyor lines 21 can be provided, the loading robot 1 places the battery E to be processed on the first clamp C1 of the first conveyor line 11, and the first conveyor line 11 conveys the battery E to be processed to the long side welding position of the top cover for welding the long side of the top cover. After the welding is completed, the first conveyor line 11 conveys the battery E with the long side of the top cover welded to the second end 11b, and the first separation conveyor line 211 at the second position W2 receives the first clamp C1, and the second separation conveyor line 212 at the third position W3 receives the battery E to be processed. Receive the unloaded second clamp C2 from the second conveyor line 12, the position change robot 2 picks up the battery E with the long side of the top cover welded by the first clamp C1 and places it on the unloaded second clamp C2 of the second conveyor line 12, and the second conveyor line 12 transports the battery E with the short side of the top cover to be welded on the second clamp C2 to the welding position of the short side of the top cover for welding the short side of the top cover. After welding is completed, the second conveyor line 12 transports the battery E with the long and short sides of the top cover welded to the unloading station, and unloads it through the unloading robot 3.

[0100] Driven by the separation drive 22, the first separation conveyor line 211 switches from the second position W2 to the first position W1 with the first clamp C1, and the second separation conveyor line 212 switches from the third position W3 to the second position W2 with the second clamp C2. At the first position W1, the first separation conveyor line 211 transports the first clamp C1 back to the first conveyor line 11. At the second position W2, the second separation conveyor line 212 transports the unloaded second clamp C2 back to the second conveyor line 12.

[0101] In this reciprocating cycle, two conveyor line bodies are set through a cutting device 20, so that the first clamp C1 circulates on the first circulating conveyor line 10a, and the second clamp C2 circulates on the second circulating conveyor line 10b, thereby continuously completing the welding of the long side and short side of the top cover.

[0102] The above embodiment describes in detail the situation where two conveyor line bodies share one cutting device 20. It is understandable that the number of conveyor line bodies can be multiple, such as three, four, five or more, and two adjacent conveyor line bodies share one cutting device 20, thereby forming multiple circulating conveyor lines to meet multiple process technology requirements. As an example, refer to Figure 5 , shows three conveyor line bodies, namely a first conveyor line body 11, a second conveyor line body 12 and a third conveyor line body 13 arranged along a first direction, and a cutting device 20 is arranged between the first conveyor line body 11 and the second conveyor line body 12 and between the second conveyor line body 12 and the third conveyor line body 13.

[0103] As an example, see Figures 1 to 5 In each conveyor line body 10, taking the first conveyor line body 11 as an example, the first conveyor line body 11 includes two second linear motors extending along the first direction X and parallel to each other, and the two second linear motors are respectively provided with cutting devices 20 on both sides along the second direction Y, wherein the cutting device 20 on one side is a part of the first conveyor line body 11, that is, the first conveyor line body 11 is spliced ​​into a U-shaped conveyor line body by two second linear motors parallel to each other and a cutting device 20. Of course, the conveyor line body 10 can also be a U-shaped conveyor line body with an integrated structure.

[0104] The U-shaped conveyor line body is formed by splicing two mutually parallel second linear motors and a cutting device 20, which is convenient for combining to form multiple circulating conveyor lines.

[0105] In some embodiments, multiple conveyor lines 10 include a first conveyor line 11, a second conveyor line 12 and a third conveyor line 13 arranged at intervals along a first direction X, and the third conveyor line 13 is located between the first conveyor line 11 and the second conveyor line 12; the cutting device 20 is arranged on the opposite sides of the multiple conveyor lines along a second direction Y, and the second direction Y intersects with the first direction X; wherein the cutting drive 22 is configured to drive the cutting conveyor line 21 to move along the second direction Y and alternately dock with the first conveyor line 11, the second conveyor line 12 and the third conveyor line 13, so that the first conveyor line 11, the cutting device 20 and the third conveyor line 13 form a first circular conveyor line 10a, and the second conveyor line 12, the cutting device 20 and the third conveyor line 13 form a second circular conveyor line 10b.

[0106] The cut-off conveyor line 21 can be docked with the first conveyor line 11 to receive the load from the first conveyor line 11, or to transport the load back to the first conveyor line 11. The cut-off conveyor line 21 can be docked with the second conveyor line 12 to receive the load from the second conveyor line 12, or to transport the load back to the second conveyor line 12. The cut-off conveyor line 21 can be docked with the third conveyor line 13 to receive the load from the third conveyor line 13, or to transport the load back to the third conveyor line 13.

[0107] The third conveyor line body 13 is a region shared by the first and second circulating conveyor lines 10a and 10b, that is, a region where the conveying path of the first and second circulating conveyor lines 10a and 10b overlap.

[0108] As an example, see Figure 6 In the separation device 20 on one side of the second direction Y, the separation conveying line body 21 is docked with the first conveying line body 11, and receives the first clamp transported from the first conveying line body 11. Under the drive of the separation driving member 22, the separation conveying line body 21 moves along the first direction X to dock with the third conveying line body 13, and transports the first clamp to the third conveying line body 13, and the third conveying line body 13 transports the first clamp along the second direction Y; in the separation device 20 on the other side of the second direction Y, the separation conveying line body 21 is docked with the third conveying line body 13, and receives the first clamp transported from the third conveying line body 13. Under the drive of the separation driving member 22, the separation conveying line body 21 moves along the first direction X to dock with the first conveying line body 11, and transports the first clamp back to the first conveying line body 11. Thus, the separation devices 20 on both sides of the second direction Y and the first conveying line body 11 and the third conveying line body 13 constitute a first circulating conveying line 10a.

[0109] In the separation device 20 on one side of the second direction Y, under the drive of the separation drive 22, the separation conveying line body 21 moves along the first direction X to dock with the second conveying line body 12, receives the second clamp transported from the second conveying line body 12, and under the drive of the separation drive 22, the separation conveying line body 21 moves along the first direction X to dock with the third conveying line body 13, transports the second clamp to the third conveying line body 13, and the third conveying line body 13 transports the first clamp along the second direction Y; along the second In the cutting device 20 on the other side of direction Y, the cutting conveyor line body 21 is docked with the third conveyor line body 13, and receives the first clamp transported from the third conveyor line body 13. Driven by the cutting drive 22, the cutting conveyor line body 21 moves along the second direction Y to dock with the second conveyor line body 12, and transports the second clamp back to the second conveyor line body 12. Thus, the cutting device 20 on both sides of the second direction Y and the second conveyor line body 12 and the third conveyor line body 13 form a second circulating conveyor line 10b.

[0110] The cutting device 20 and the first conveyor line body 11, the cutting device 20 and the third conveyor line body 13 form two circulating conveyor lines, wherein the third conveyor line body 13 is shared by the two circulating conveyor lines, which can improve the conveying efficiency and reduce the occupied space.

[0111] In some embodiments, the separation drive 22 is configured to drive the separation conveying line 21 to reciprocate between the first position W1, the second position W2, and the third position W3 along the first direction X; Among them, in the first position W1, the cut-off conveyor line body 21 is connected to the end of the first conveyor line body 11 along the second direction Y, in the second position W2, the cut-off conveyor line body 21 is connected to the end of the third conveyor line body 13 along the second direction Y, and in the third position W3, the cut-off conveyor line body 21 is connected to the end of the second conveyor line body 12 along the second direction Y.

[0112] As an example, in the cutting devices 20 on both sides along the second direction Y, the cutting conveying line 21 of the cutting device 20 on one side receives the first clamp transported from the first conveying line 11 at one end of the first conveying line 11 along the second direction Y, and the cutting conveying line 21 of the cutting device 20 on the other side transports the first clamp back to the first conveying line 11 at the other end of the first conveying line 11 along the second direction Y.

[0114] Therefore, in the two circulating conveyor lines, the third conveyor line body 13 is completely shared, so that the overall structure of the conveyor line 100 is more compact and the occupied area can be further reduced.

[0115] In some embodiments, reference Figure 6 The separation conveyor line 21 includes a first separation conveyor line 211 and a second separation conveyor line 212, and the separation drive 22 is configured to drive the first separation conveyor line 211 to reciprocate between a first position W1 and a second position W2 along a first direction X and to drive the second separation conveyor line 212 to reciprocate between a second position W2 and a third position W3 along the first direction X; wherein, when the first separation conveyor line 211 reaches the first position W1, the second separation conveyor line 212 reaches the second position W2, and when the first separation conveyor line 211 reaches the second position W2, the second separation conveyor line 212 reaches the third position W3; in the first position W1, the first separation conveyor line 211 is docked with the first conveyor line 11, and in the second position W2, the first separation conveyor line 211 and the second separation conveyor line 212 are docked with the third conveyor line 13 respectively, and in the third position W3, the second separation conveyor line 212 is docked with the second conveyor line 12.

[0116] In the first position W1, the first cut-off conveyor line body 211 can receive the first clamp transported from the first conveyor line body 11, or transport the first clamp back to the first conveyor line body 11; in the second position W2, the first cut-off conveyor line body 211 can transport the first clamp to the third conveyor line body 13, or receive the first clamp from the third conveyor line body 13.

[0118] Two separation conveyor line bodies (a first separation conveyor line body 211 and a second separation conveyor line body 212) are set through a separation device 20, wherein when the first separation conveyor line body 211 reaches the first position W1, the second separation conveyor line body 212 reaches the second position W2, and when the first separation conveyor line body 211 reaches the second position W2, the second separation conveyor line body 212 reaches the third position W3, thereby, the two separation conveyor line bodies move back and forth synchronously, thereby forming two circulating conveyor lines with the first conveyor line body 11, the second conveyor line body 12 and the third conveyor line body 13 respectively, and the two circulating conveyor lines can be operated synchronously, further accelerating the production rhythm and improving production efficiency.

[0119] In some embodiments, in the separation device 20 on one side of the second direction Y, at the first position W1, the first separation conveyor line 211 receives the first carrier transported from the first conveyor line 11, and transports the first carrier to the second position W2 under the drive of the separation drive 22, and at the second position W2, the first separation conveyor line 211 transports the first carrier to the third conveyor line 13; at the third position W3, the second separation conveyor line 212 receives the second carrier transported from the second conveyor line 12, and transports the second carrier to the second position W2 under the drive of the separation drive 22, and at the second position W2, the second separation conveyor line 212 transports the second carrier to the third conveyor line body 13; in the separation device 20 on the other side of the second direction Y, in the second position W2, the first separation conveyor line 211 receives the first carrier transported from the third conveyor line 13, and transports the first carrier to the first position W1 under the drive of the separation drive 22. In the first position W1, the first separation conveyor line 211 transports the first carrier to the first conveyor line 11; in the second position W2, the second separation conveyor line 212 receives the second carrier transported from the third conveyor line 13, and transports the second carrier to the third position W3 under the drive of the separation drive 22.

The first clamp C1 is used to clamp the narrow side of the battery E, so as to meet the welding process requirements of the long side of the top cover. The second clamp C2 is used to clamp the large side of the battery E, so as to meet the welding process requirements of the short side of the top cover.

[0121] The loading robot 1 places the battery E to be processed on the first fixture C1 of the first conveyor line 11, and the first conveyor line 11 conveys the first fixture C1 carrying the battery E to be processed to the long side welding station for welding the long side of the top cover. After welding, the first conveyor line 11 drives the first fixture C1 carrying the battery E with the long side of the top cover welded away from the long side welding station; the first separation conveyor line 211 in the separation device 20 along the second direction Y side (the left side in the figure) reaches the first position W1 under the drive of the separation drive 22, and at the first position W1 The first separation conveyor line 211 receives the first clamp C1 carrying the battery E with the long side of the top cover welded thereon, which is transported from the first conveyor line 11. The first separation conveyor line 211 is driven by the separation drive 22 to move from the first position W1 to the second position W2. At the second position W2, the first separation conveyor line 211 transports the first clamp C1 carrying the battery E with the long side of the top cover welded thereon to the third conveyor line 13. The first separation conveyor line 211 is driven by the separation drive 22 to move from the first position W1 to the second position W2. At the same time, the second separation conveyor line 212 arrives at the third position W3 from the second position W2. At the third position W3, the second separation conveyor line 212 receives the empty second clamp C2 delivered by the second conveyor line 12; the first separation conveyor line 211 returns to the first position W1 from the second position W2 under the drive of the separation drive 22, and continues to receive the next first clamp C1 carrying the battery E with the long side of the top cover welded from the first conveyor line 11. At the same time, the second separation conveyor line 212 arrives at the third position W3 from the second position W2. The second position W2, and the unloaded second fixture C2 is transported to the third conveyor line 13; the third conveyor line 13 transports the first fixture C1 carrying the battery E with the long side of the top cover welded to the hand-changing position, the position-changing robot 2 picks up the battery E with the long side of the top cover welded on the first fixture C1, and turns it 90°, and the third conveyor line 13 drives the unloaded first fixture C1 away from the hand-changing position; the unloaded second fixture C2 on the third conveyor line 13 arrives at the hand-changing position, and the position-changing robot 2 places the battery E after turning 90° on the second fixture C2;The first separation conveyor line 211 in the separation device 20 on the other side of the second direction Y (the right side in the figure) reaches the second position W2 under the drive of the separation drive 22, receives the empty first clamp C1 transported from the third conveyor line 13, and the first separation conveyor line 211 returns from the second position W2 to the first position W1 under the drive of the separation drive 22. At the first position W1, the first separation conveyor line 211 transports the empty first clamp C1 back to the first conveyor line 11, and the second separation conveyor line 212 reaches the second position W2 from the third position W3. At the second position W2, the second separation conveyor line 212 The second fixture C2 carrying the flipped battery E is received from the third conveyor line 13. Under the drive of the separation drive 22, the second separation conveyor line 212 moves from the second position W2 to the third position W3. At the third position W3, the second separation conveyor line 212 conveys the second fixture C2 carrying the flipped battery E to the second conveyor line 12. The second conveyor line 12 conveys the second fixture C2 carrying the flipped battery E to the short side welding station for welding the short side of the top cover. After welding, it is transported to the unloading station via the second conveyor line 12. The unloading manipulator 3 picks up the battery E on the second fixture C2 for unloading. This reciprocating cycle is repeated to achieve uninterrupted completion of the welding of the long and short sides of the top cover. ;

[0122] Thus, while improving production efficiency, due to the shared use of the third conveyor line body 13, the position-changing robot 2 can switch the posture of the battery E in situ, further speeding up the production rhythm, simplifying the structure and reducing the floor space.

The two separation devices are staggered along the second direction Y, so that the two circulating conveyor lines (the first circulating conveyor line 10a and the second circulating conveyor line 10b) share part of the third conveyor line body 13. The posture of the battery E can also be switched in situ.
