Description

Technical Field

[0001] This invention relates to the field of material handling technology, and in particular to a feeding device. Background Technology

[0002] With the popularization of new energy vehicles, new energy batteries have also developed rapidly. In the production process of new energy battery cells, battery electrode rolls, which are raw materials for battery production, need to be transferred to a winding platform for winding.

[0003] In traditional battery manufacturing processes, AGVs are often used to directly load battery electrode rolls onto the winding platform. However, each AGV can only transport one electrode roll at a time, resulting in insufficient turnover efficiency. To meet production demands, AGVs need to make multiple round trips, leading to excessive downtime on the winding platform and prolonged AGV usage on a single machine, thus affecting production efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a feeding device to address the issue of how to improve production efficiency.

[0005] The technical solution is as follows:

[0007] A main shaft for storing materials, the main shaft having an inlet for the materials to enter and an outlet for the materials to be removed;

[0008] A first support mechanism, which can be selectively connected to or detached from the incoming material end; and,

[0009] A second support mechanism, which can be selectively connected to or separated from the feeding end;

[0010] The feeding mechanism has a storage state, a loading state, and a feeding state. In the storage state, the first support mechanism is connected to the receiving end, and the second support mechanism is connected to the feeding end. In the loading state, the first support mechanism is separated from the receiving end, and the second support mechanism is connected to the feeding end. In the feeding state, the first support mechanism is connected to the receiving end, and the second support mechanism is separated from the feeding end.

[0011] The technical solution of this application will be further described below:

The first clamping member and the second clamping member are disposed opposite to each other. The first clamping member and the second clamping member have a clamping state in which they are close to each other to clamp the spindle and a separation state in which they are far apart from each other to separate from the spindle. The first driving member is used to drive the first clamping member and the second clamping member to switch between the clamping state and the separation state.

[0013] In one embodiment, the feeding device further includes a base, the base being provided with a first slide rail, the first clamping member and the second clamping member being slidably engaged with the first slide rail, and the first driving member being used to drive the first clamping member and the second clamping member to move closer to each other or further away from each other along the first slide rail.

[0014] In one embodiment, the first driving element includes:

[0015] A first lead screw extends in a direction parallel to the first slide rail. The first lead screw has a first threaded section and a second threaded section. The thread direction of the first threaded section is opposite to that of the second threaded section. A first clamping member is threadedly connected to the first threaded section, and a second clamping member is threadedly connected to the second threaded section.

[0016] A first motor is connected to the first lead screw and is used to drive the first lead screw to rotate.

[0017] In one embodiment, the feeding device further includes a base, and the first clamping member and the second clamping member are rotatably connected to the base. The first driving member is used to drive the first clamping member and the second clamping member to rotate in opposite directions or in opposite directions.

[0018] In one embodiment, the first clamping member is provided with a movable locking member, and the second clamping member is provided with a first locking hole. The locking member can be inserted into the first locking hole to lock the clamping state of the first clamping member and the second clamping member; the locking member can be removed from the first locking hole to release the locking of the first clamping member and the second clamping member.

[0019] In one embodiment, both the first support mechanism and the second support mechanism include a support portion, a clamping portion, and a second driving member. The clamping portion is disposed on the support portion and is used to clamp or release the spindle. The second driving member is connected to the support portion and is used to drive the support portion to move closer to or away from the spindle.

[0020] In one embodiment, the clamping part includes a first clamping block and a second clamping block. The first clamping block is connected to the support part, and one end of the second clamping block is rotatably connected to one end of the first clamping block via a rotating shaft. The second clamping block can rotate around the rotating shaft to clamp or release the spindle together with the first clamping block.

[0021] In one embodiment, the feeding device further includes a feeding mechanism, which is disposed adjacent to the main shaft and is used to drive the material to move along the main shaft.

[0022] In one embodiment, the feeding mechanism includes:

[0023] A bracket, wherein the bracket is provided with a second slide rail parallel to the extension direction of the main shaft;

[0024] A slide table, wherein the slide table is slidably engaged with the second slide rail;

[0025] A lever, one end of which is rotatably connected to a slide table, the lever having a material-pulling position for abutting against the material and a clearance position for avoiding the material;

[0026] A third driving member, disposed on the slide and connected to the lever, is used to drive the lever to rotate between the feeding position and the clearance position; and...

[0027] A fourth driving member is connected to the slide table and is used to drive the slide table to move along the second slide rail.

[0028] In one embodiment, the feeding device further includes a first auxiliary support mechanism and a second auxiliary support mechanism. The first auxiliary support mechanism is arranged adjacent to the first support mechanism and is used to support the incoming material end.

[0029] In one embodiment, both the first auxiliary support mechanism and the second auxiliary support mechanism include:

[0030] Adapter;

[0031] A support member, one end of which is rotatably connected to the adapter seat;

[0032] A fifth driving member is connected to the support member and is used to drive the support member to rotate around the adapter seat so that the end of the support member away from the adapter seat supports the main shaft or is separated from the main shaft.

[0033] The aforementioned feeding device, by setting a detachable first support mechanism at the receiving end of the main shaft and a detachable second support mechanism at the feeding end, enables unobstructed feeding of materials from the receiving end into the main shaft for storage, and unobstructed removal of materials stored on the main shaft from the feeding end. When applied to storing and feeding electrode rolls, it can be positioned between the receiving mechanism and the winding platform. Before production, multiple electrode rolls can be pre-loaded onto the main shaft via an AGV trolley, expanding the electrode roll inventory of a single winding platform. During production, the winding platform can directly retrieve electrode rolls from the feeding end of the main shaft, avoiding the problem of excessive downtime for the winding platform due to frequent AGV trolley transport, and also avoiding the problem of a single winding platform occupying the AGV trolley for too long, thereby improving production efficiency.

Detailed Implementation

[0045] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] Specifically, one embodiment of this application provides a feeding mechanism. In the new energy battery production process, the feeding mechanism can be set between the winding platform and the AGV trolley to temporarily store the electrode rolls 60 transported by the AGV trolley and transfer the electrode rolls 60 to the winding platform. It is worth noting that the feeding mechanism of this application can also be used for the storage and transfer of other materials, and is not limited thereto. See also... Figures 1 to 3 One embodiment of the feeding mechanism includes a main shaft 40, a first support mechanism 11 and a second support mechanism 12, wherein the main shaft 40 is used to store materials, the main shaft 40 has a material receiving end 41 for material entry and a material feeding end 42 for material removal, the first support mechanism 11 can be selectively connected to or separated from the material receiving end 41, and the second support mechanism 12 can be selectively connected to or separated from the material feeding end 42.

[0047] Furthermore, the feeding mechanism has a storage state, a loading state, and a feeding state. In the storage state, the first support mechanism 11 is connected to the receiving end 41 to support the receiving end 41; the second support mechanism 12 is connected to the feeding end 42 to support the feeding end 42. In the loading state, the first support mechanism 11 is separated from the receiving end 41 to allow material to be fed into the main shaft 40 from the receiving end 41, preventing the first support mechanism 11 from obstructing the material; the second support mechanism 12 is connected to the feeding end 42 to support the main shaft 40. In the feeding state, the first support mechanism 11 is connected to the receiving end 41 to support the main shaft 40, and the second support mechanism 12 is separated from the feeding end 42 to allow material to be removed from the feeding end 42, preventing the second support mechanism 12 from obstructing the material.

[0048] Specifically, taking the process of storing and loading electrode rolls 60 using a loading device as an example, when loading needs to be done, the receiving mechanism (AGV trolley) carries the electrode rolls 60 to the receiving end 41 of the main shaft 40 and docks with it. Then, the first support mechanism 11 separates from the receiving end 41 to prevent it from blocking the electrode rolls 60. At this time, the main shaft 40 is supported by the second support mechanism 12. Then, the receiving mechanism puts the electrode rolls 60 onto the main shaft 40 from the receiving end 41. After the receiving mechanism finishes loading the main shaft 40, the first support mechanism 11 reconnects to the receiving end 41 to support the main shaft 40 together with the second support mechanism 12. Then, the docking between the receiving mechanism and the receiving end 41 of the main shaft 40 can be disconnected, thus completing the loading process for the loading device.

[0049] When feeding material to the winding platform, the feeding end 42 is connected to the winding platform. Then, the second support mechanism 12 is separated from the feeding end 42 to prevent the second support mechanism 12 from blocking the electrode roll 60. At this time, the main shaft 40 is supported by the first support mechanism 11. Then, the electrode roll 60 on the main shaft 40 can be pushed from the feeding end 42 to the winding platform. Subsequently, the second support mechanism 12 is reconnected to the feeding end 42 so that the second support mechanism 12 and the first support mechanism 11 jointly support the main shaft 40. Finally, the connection between the feeding end 42 of the main shaft 40 and the winding platform can be disconnected, completing the feeding of material to the winding platform.

[0050] The aforementioned feeding device, by providing a detachable first support mechanism 11 at the receiving end 41 of the main shaft 40 and a detachable second support mechanism 12 at the feeding end 42, enables unobstructed feeding of materials from the receiving end 41 into the main shaft 40 for storage, and also allows unobstructed removal of materials stored on the main shaft 40 from the feeding end 42. When applied to storing and feeding electrode rolls 60, the feeding device can be positioned between the receiving mechanism and the winding platform. Before production, multiple electrode rolls 60 can be pre-loaded onto the main shaft 40 via an AGV trolley, expanding the electrode roll 60 inventory of a single winding platform. During production, the winding platform can directly retrieve electrode rolls 60 from the feeding end 42 of the main shaft 40, avoiding the problem of excessive downtime for the winding platform due to frequent AGV trolley transport, and also avoiding the problem of a single winding platform occupying the AGV trolley for too long, thereby improving production efficiency.

[0051] Optionally, in the first embodiment, the first support mechanism 11 and the second support mechanism 12 have the same structure, both including a first clamping member 111, a second clamping member 112, and a first driving member 13. The first clamping member 111 and the second clamping member 112 are arranged opposite to each other, and have a clamping state for clamping the main shaft 40 and a separated state for separating from the main shaft 40. In the clamping state, the first clamping member 111 and the second clamping member 112 are close to each other to jointly clamp the main shaft 40. In the separated state, the first clamping member 111 and the second clamping member 112 are far apart from each other to separate from the main shaft 40, thereby avoiding interference with the material placed into or removed from the main shaft 40. The first driving member 13 is used to drive the first clamping member 111 and the second clamping member 112 to switch between the clamping state and the separated state.

[0052] Furthermore, the surfaces of the first clamping member 111 and the second clamping member 112 opposite each other are provided with receiving grooves that match the spindle 40. In the clamping state, the first clamping member 111 and the second clamping member 112 are clamped together on the outside of the spindle 40 through the receiving grooves, thereby improving the clamping stability of the spindle 40.

[0053] See also Figure 1 The feeding device also includes a base 30, which is provided with a first slide rail 31. Both the first clamping member 111 and the second clamping member 112 are slidably engaged with the first slide rail 31. A first driving member 13 is used to drive the first clamping member 111 and the second clamping member 112 to move closer together along the first slide rail 31 so that the first clamping member 111 and the second clamping member 112 jointly clamp the spindle 40. The first driving member 13 is also used to drive the first clamping member 111 and the second clamping member 112 to move further apart along the first slide rail 31 to avoid material.

[0054] Furthermore, the first driving member 13 includes a first lead screw 132 and a first motor 131 connected to the first lead screw 132, wherein the first lead screw 132 extends in a direction parallel to the first slide rail 31, the first lead screw 132 has a first threaded section (not shown) and a second threaded section (not shown), the thread direction of the first threaded section is opposite to the thread direction of the second threaded section, the first clamping member 111 is threadedly connected to the first threaded section, and the second clamping member 112 is threadedly connected to the second threaded section. The first motor 131 is used to drive the first lead screw 132 to rotate. Since the thread direction of the first threaded section of the first lead screw 132 is opposite to that of the second threaded section, the first motor 131 can drive the first lead screw to rotate, thereby simultaneously driving the first clamping member 111 and the second clamping member 112 to move closer or further apart along the first slide rail 31. This saves costs and improves the synchronization of the movement of the first clamping member 111 and the second clamping member 112, ensuring that the first clamping member 111 and the second clamping member 112 can clamp or release the spindle 40 at the same time.

[0055] It is worth noting that in other embodiments, the first driving member 13 may also be an electric push rod, a gear and rack mechanism, or a synchronous belt mechanism, as long as it can drive the first clamping member 111 and the second clamping member 112 to move closer to or further away from each other, and there are no restrictions here.

[0056] Optionally, in one embodiment, the first clamping member 111 is provided with a movable locking member 14, and the second clamping member 112 is provided with a first locking hole 141. When the first clamping member 111 and the second clamping member 112 are in a clamping state, the locking member 14 can pass through the first locking hole 141, thereby locking the first clamping member 111 and the second clamping member 112. When it is necessary to separate the first clamping member 111 and the second clamping member 112, the locking member 14 is removed from the first locking hole 141 to release the lock on the first clamping member 111 and the second clamping member 112. At this time, the first driving member 13 can drive the first clamping member 111 and the second clamping member 112 to separate in a direction away from each other.

[0057] Optionally, in one embodiment, the feeding device further includes a feeding mechanism 20, which is disposed adjacent to the main shaft 40 and is used to drive the material to move along the main shaft 40. Specifically, the main shaft 40 also includes a storage area disposed between the feeding end 42 and the receiving end 41, and the feeding mechanism 20 is used to drive the material from the receiving end 41 into the storage area, or to send the material from the storage area out of the main shaft 40 via the feeding end 42.

[0058] Specifically, see Figure 1One embodiment of the material feeding mechanism 20 includes a bracket 21, a slide table 25, a lever 22, a third driving member 23, and a fourth driving member 24. The bracket 21 has a second slide rail 211 parallel to the extending direction of the main shaft 40. The slide table 25 is slidably engaged with the second slide rail 211. One end of the lever 22 is rotatably connected to the slide table 25. The lever 22 has a feeding position for abutting against material and a clearance position for avoiding material. The third driving member 23 is disposed on the slide table 25 and connected to the lever 22. The third driving member 23 drives the lever 22 to rotate between the feeding position and the clearance position. The fourth driving member 24 is connected to the slide table 25 and drives the slide table 25 to move along the second slide rail 211. Preferably, the third driving member 23 can be a cylinder, a hydraulic cylinder, or an electric push rod, as long as it can drive the lever 22 to rotate around the slide table 25; no limitation is made here. The fourth driving component 24 can be a lead screw mechanism, a gear and rack mechanism, or an electric push rod, etc., as long as it can drive the slide table 25 to move back and forth along the second slide rail 211. There are no restrictions here.

[0059] Furthermore, taking the actuation of the electrode roll 60 as an example, after the feeding mechanism feeds the electrode roll 60 into the feeding end 41, the fourth driving member 24 drives the slide table 25 to the side of the electrode roll 60 away from the storage area. Then, the third driving member 23 drives the lever 22 to rotate to the feeding position, so that the lever 22 abuts against the side of the electrode roll 60 away from the storage area. Then, the fourth driving member 24 drives the slide table 25 to move closer to the storage area, thereby driving the lever 22 to move the electrode roll 60 into the storage area for temporary storage. After the electrode roll 60 is moved into place, the third driving member 23 drives the lever 22 back to the avoidance position to avoid interference between the lever 22 and the electrode roll 60 during the subsequent movement of the slide table 25.

[0060] Similarly, when it is necessary to feed material onto the winding platform, the feeding end 42 is connected to the winding platform, and then the second support mechanism 12 is separated from the feeding end 42. Then, the fourth drive member 24 moves the slide table 25 to the side of the pole roll 60 closest to the feeding end 42 away from the winding platform. Then, the third drive member 23 drives the lever 22 to rotate to the material feeding position, so that the lever 22 abuts against the side of the pole roll 60 away from the winding platform. Then, the fourth drive member 24 drives the slide table 25 to move towards the winding platform, thereby driving the lever 22 to move the pole roll 60 from the storage area to the winding platform. Then, the remaining pole roll 60 is moved back to the storage area from the feeding end 42 by the material feeding mechanism 20 to prevent the pole roll 60 from being in the feeding end 42 due to movement, which would affect the subsequent support of the feeding end 42 by the second support mechanism 12. When it is necessary to feed material onto the winding platform again, the above steps are repeated.

[0061] It is worth noting that in other embodiments, the feeding mechanism 20 can also be a push rod or a cylinder or other driving mechanism, as long as it can drive the material to move along the main shaft 40, and there are no restrictions here.

[0062] See also Figures 1 to 3 Optionally, in one embodiment, the feeding device further includes a first auxiliary support mechanism 51 and a second auxiliary support mechanism 52. The first auxiliary support mechanism 51 is disposed adjacent to the first support mechanism 11 and is used to support the receiving end 41. The second auxiliary support mechanism 52 is disposed adjacent to the second support mechanism 12 and is used to support the feeding end 42. Specifically, the first auxiliary support mechanism 51 is used to support the receiving end 41 of the main shaft 40 after the receiving mechanism has finished loading material onto the main shaft 40 and before the first support mechanism 11 has re-supported the receiving end 41, in order to correct the tilting problem of the receiving end 41 of the main shaft 40, so that the first support mechanism 11 can then accurately connect with the receiving end 41. Similarly, the second auxiliary support mechanism 52 is used to support the feeding end 42 of the main shaft 40 after the feeding onto the winding platform has been completed and before the second support mechanism 12 has re-supported the feeding end 42, in order to correct the tilting problem of the feeding end 42 of the main shaft 40, so that the second support mechanism 12 can then accurately connect with the feeding end 42.

[0063] Specifically, see Figure 2 In one embodiment, both the first auxiliary support mechanism 51 and the second auxiliary support mechanism 52 include an adapter 511, a support member 513, and a fifth driving member 512. The adapter 511 is fixed to the base 30, and one end of the support member 513 is connected to the adapter 511. The fifth driving member 512 is connected to the support member 513 and is used to drive the support member 513 to rotate around the adapter 511, so that the end of the support member 513 away from the adapter 511 supports the main shaft 40 or is separated from the main shaft 40. Specifically, when the fifth driving member 512 drives the support member 513 to rotate to be perpendicular to the base 30, the support member 513 supports the main shaft 40. When the fifth driving member 512 drives the support member 513 to rotate to form an acute angle with the base 30, the support member 513 is separated from the main shaft 40.

[0064] Preferably, the support member 513 includes an adapter end connected to the adapter seat 511 and a support end for supporting the spindle 40. The fifth drive member 512 is a cylinder, a hydraulic cylinder, or an electric push rod. The fifth drive member 512 is connected between the adapter end and the support end of the support member 513. The distance from the connection point of the fifth drive member 512 and the support member 513 to the adapter end is less than the distance from the connection point to the support end. That is, the connection point of the fifth drive member 512 and the support member 513 is closer to the adapter end of the support member 513, thereby reducing the stroke requirement of the output shaft of the fifth drive member 512, making the fifth drive member 512 smaller and reducing the space occupied by the fifth drive member 512.

[0065] See Figure 4 as well as Figure 5 , Figure 4 as well as Figure 5The structure of the feeding device in the second embodiment is illustrated. Figure 1 Unlike the first embodiment of the feeding device, in the second embodiment, both the first clamping member 111 and the second clamping member 112 are rotatably connected to the base 30, and the first driving member 13 is used to drive the first clamping member 111 and the second clamping member 112 to rotate in opposite directions. Specifically, when the first driving member 13 drives the first clamping member 111 and the second clamping member 112 to rotate in opposite directions, the end of the first clamping member 111 away from the base 30 and the end of the second clamping member 112 away from the base 30 move closer to each other, thereby clamping the main shaft 40. When the first driving member 13 drives the first clamping member 111 and the second clamping member 112 to rotate in opposite directions, the end of the first clamping member 111 away from the base 30 and the end of the second clamping member 112 away from the base 30 move further apart, thereby separating from the main shaft 40, thus avoiding obstruction of material being placed into or removed from the main shaft 40. Preferably, in the second embodiment, the first driving member 13 can be a cylinder, a hydraulic cylinder, or an electric push rod, and the first clamping member 111 and the second clamping member 112 are each connected to a first driving member 13, thereby driving the first clamping member 111 and the second clamping member 112 to rotate in opposite directions or in opposite directions respectively.

[0066] It is worth noting that the other mechanisms of the feeding device in the second embodiment can be the same as those in the feeding device in the first embodiment, and will not be described in detail here.

[0067] See Figure 6 as well as Figure 7 , Figure 6 as well as Figure 7 The structure of the feeding device in the third embodiment is illustrated. Figure 1 The feeding device of the first embodiment shown and Figure 4 Unlike the feeding device of the second embodiment, the first support mechanism 11 and the second support mechanism 12 of the feeding device in the third embodiment both include a support part 121, a clamping part, and a second driving member 32. The clamping part is disposed on the support part 121 and is used to clamp or release the main shaft 40. The second driving member 32 is connected to the support part 121 and is used to drive the support part 121 to move closer to or away from the main shaft 40. Specifically, when it is necessary to support the main shaft 40, the second driving member 32 drives the support part 121 to move below the main shaft 40, and then clamps the main shaft 40 through the clamping part, thereby achieving stable support for the main shaft 40. When it is necessary to put material into the main shaft 40 or take material out of the main shaft 40, the clamping part releases the main shaft 40, and then the second driving member 32 drives the support part 121 away from the main shaft 40 to avoid blocking the material from being put into or taken out of the main shaft 40.

[0068] Furthermore, in the third embodiment, the base 30 of the feeding device is provided with a first slide rail 31, the support part 121 is slidably engaged with the first slide rail 31, and the second driving member 32 is used to drive the support part 121 to slide along the first slide rail 31, so that the support part 121 moves closer to or away from the main shaft 40. It is worth noting that in another embodiment, the support part 121 may also be rotatably connected to the base 30, so that driving the support part 121 to rotate via the second driving member 32 can also achieve the effect of moving the support part 121 closer to or away from the main shaft 40.

[0069] See also Figure 6 The clamping part includes a first clamping block 122 and a second clamping block 123. The first clamping block 122 is connected to the support part 121. One end of the second clamping block 123 is connected to one end of the first clamping block 122 via a rotating shaft 124.

[0070] The second clamping block 123 is dynamically connected and can rotate around the rotating shaft 124 to clamp or release the main shaft 40 together with the first clamping block 122. Further, in this embodiment, the second clamping block 123 can be manually rotated by a worker to clamp or release the main shaft 40. In other embodiments, the second clamping block 123 can also be mechanically driven to rotate; specifically, it can be driven to rotate by a motor or gear mechanism, ultimately causing the second clamping block 123 to clamp or release the main shaft 40.

[0071] Optionally, in one embodiment, a locking member (not shown) is provided at the end of the first clamping block 122 away from the rotating shaft 124 and the end of the second clamping block 123 away from the rotating shaft 124. The locking member is used to lock the first clamping block 122 and the second clamping block 123 when they clamp the spindle 40, thereby ensuring the stability of the spindle 40 when clamped by the first clamping block 122 and the second clamping block 123. The locking member can also release the lock on the first clamping block 122 and the second clamping block 123, so that the second clamping block 123 can rotate freely, thereby releasing the spindle 40.

[0072] Shaft 40. Preferably, the locking element can be a pin, which can lock the first clamp 122 and the second clamp 123 by inserting the pin into the first clamp 122 and the second clamp 123, and release the lock on the first clamp 122 and the second clamp 123 by pulling out the pin.

[0073] Preferably, the surfaces of the first clamping block 122 and the second clamping block 123 opposite to each other are provided with grooves that match the spindle 40. The first clamping block 122 and the second clamping block 123 can be clamped together on the spindle 40 through the grooves, thereby improving the clamping stability of the spindle 40.
