Technical Field

[0001] The present application relates to the technical field of battery assembly, and in particular to a feeding mechanism and a battery production system. Background Art

[0002] The existing automatic workstation feeding racks of battery production lines use multi-layer material storage, and the machine arm is used to grab materials from the material frames at different heights. However, for some narrow plots of space, the machine arm is often not suitable, which affects the user experience. Summary of the invention

[0003] Based on this, it is necessary to provide a feeding mechanism and a battery production system to address the problem that existing feeding equipment cannot be used in a small space.

[0004] The first aspect of an embodiment of the present application provides a feeding mechanism, comprising: a frame; a plurality of loading mechanisms, which are movably arranged on the frame; a feeding assembly, which has a material taking position for external material taking and a plurality of feeding positions; a lifting device, which is used to drive the feeding assembly to switch between the material taking position and the plurality of feeding positions; and a plurality of material trolleys, which are respectively arranged on the corresponding loading mechanisms; when the feeding assembly is in the corresponding feeding position, the material trolley can be transferred from the corresponding loading mechanism to the feeding assembly.

[0005] In this way, during the entire production process, the feeding assembly can reach feeding positions at different heights through the lifting device, thereby facilitating the transfer of material carts on different loading mechanisms to the feeding assembly and realizing multi-position loading; since the material picking position of the feeding assembly is at a fixed height, the mechanical arm can uniformly pick up materials at the material picking position at the same height, thereby eliminating the need to design complex mechanism deformation, reducing costs, and avoiding the space requirements of the mechanical arm during the deformation process, so that the matching feeding mechanism can be used in a small space.

[0006] In one embodiment, the rack includes multiple layers of storage space, each layer of the storage space forms a first opening and a second opening on both sides of the rack along the thickness direction; each group of the loading mechanism is movably arranged in the corresponding storage space, and can extend from the first opening of the storage space to the outside of the storage space; the feeding assembly is arranged on one side along the thickness direction of the rack, and the material picking position and multiple feeding positions are arranged along the height direction of the rack; when the feeding assembly is in the corresponding feeding position, the material trolley can be transferred from the second opening corresponding to the storage space to the feeding assembly. In this way, the material trolley can be loaded at multiple positions, and the production process of unifying the material picking by fixing it at the picking position through the mechanical arm can be realized; in addition, since the mechanical arm does not need to design complex mechanism deformation, the structure is simple and can effectively reduce costs, and the space requirements of the mechanical arm are also avoided, and finally the matching feeding mechanism can be used in a small plot space, expanding the application scenario range of the feeding mechanism.

[0007] In one embodiment, the rack includes a plurality of cross bars, a bottom plate, a top plate, a left vertical plate, and a right vertical plate; the top plate is arranged opposite to the bottom plate, the left vertical plate is arranged opposite to the right vertical plate and supported between the bottom plate and the top plate; a plurality of cross bars are connected between the left vertical plate and the right vertical plate to separate the storage space.

In this way, the storage space and the feeding mechanism can be locked, which facilitates the transfer of the material trolley from the feeding mechanism to the feeding assembly. In addition, it can also prevent the feeding mechanism from sliding out of the first opening of the storage space when the feeding mechanism on other layers transfers materials, thereby avoiding affecting work efficiency.

[0009] In one embodiment, the feeding mechanism includes two groups of slide rails, two groups of sliding rods, a door panel, a hook and a push-pull drive member; in one group of the feeding mechanism, the two groups of the slide rails are in the corresponding storage space and are respectively fixed on the left vertical plate and the right vertical plate; the two groups of the sliding rods are respectively slidably set on the two groups of the slide rails; the door panel is erected at the ends of the two groups of the slide rails, and the hook is movably set on the side of the door panel facing the first opening; the push-pull drive member is arranged on the door panel to drive the hook to move left and right; when the feeding mechanism is located in the corresponding storage space, the door panel covers the first opening. In this way, the door panel covers the first opening, thereby closing the storage space and avoiding external interference; the push-pull drive component can push the hook to move horizontally to the left for a distance, so as to facilitate the connection between the hook and the hooking part on the material trolley, thereby fixing the loading mechanism and the material trolley and avoiding position displacement of the material trolley during the loading mechanism entering and exiting the storage space; the push-pull drive component pulls the hook to move horizontally to the right for a distance, so as to facilitate the separation of the hook from the hooking part on the material trolley, and the loading mechanism is separated from the material trolley; the material trolley can be transferred from the second opening corresponding to the storage space to the feeding assembly to complete the transfer of materials.

[0010] In one embodiment, the sliding rod includes a first sliding rod and a second sliding rod, the first sliding rod is slidably arranged on the sliding rail, the second sliding rod is slidably connected to the first sliding rod, and the door panel is erected at an end of the second sliding rod away from the first sliding rod.

[0011] In one embodiment, the material trolley includes a bearing plate, a placement frame, a rolling wheel and a hooking portion; the rolling wheel is supported on the bottom surface of the bearing plate; the placement frame is arranged on the top surface of the bearing plate; the hooking portion is arranged at one end of the bearing plate close to the door panel; the hooking portion is used to hook with the hook.

In this way, the lifting device drives the feeding assembly to lift and lower between the material picking position and multiple feeding positions, thereby completing functions such as material loading and transfer.

[0014] In one embodiment, the lifting device includes a buffer, and the buffer is arranged on the slide rail connecting block. In this way, when the lifting device drives the feeding assembly to lift and switch between the material taking position and the plurality of feeding positions, the buffer can absorb vibration and extend the service life.

In this way, the material trolley is locked with the support frame by the locking member, and the lifting device drives the feeding assembly to rise from the feeding position of the bottom layer to the material picking position. At this time, the locking member remains locked to avoid relative displacement between the material trolley and the feeding assembly, so that the external mechanical arm can pick up the material on the feeding assembly at the material picking position, and finally complete the material production process.

[0016] In one embodiment, the feeding assembly includes a roller guide bar, which is disposed on the support frame and extends along the thickness direction to a side close to the second opening.

[0045] 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 aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0046] In the related art, automatic workstations on large-scale battery production lines often use feeding equipment with multi-layer storage space for feeding. The storage space of the feeding equipment is at different heights, and the machine arm is often required to move to different heights for grasping. This requires the mechanical arm structure to be more complex to adapt to grasping actions at different heights, which further leads to higher costs and more difficult maintenance of the mechanical arm. The mechanical arm requires a certain amount of space to complete the structural changes during the height adjustment process. Therefore, the feeding equipment often cannot be set up in a small space, resulting in high requirements for site space for the feeding equipment.

[0047] In order to alleviate the problem that the heavy feeding mechanism of the existing battery production system cannot be used in a small space, a unified feeding position and multiple feeding positions can be designed for the feeding mechanism. In this way, the mechanical arm can uniformly pick up materials at the material picking position, thereby eliminating the need to design complex mechanism deformation, reducing costs, and avoiding the space requirements of the mechanical arm during the deformation process, so that the matching feeding mechanism can be used in a small space.

[0048] A first aspect of an embodiment of the present application provides a feeding mechanism that can provide storage and loading for power battery production.

[0049] See also Figures 1 to 5 As shown, Figure 1 A schematic diagram of the structure of a feeding mechanism provided in some embodiments of the present application. Figure 2 A first schematic diagram of the feeding process of the feeding mechanism provided in some embodiments of the present application, wherein the bottom loading mechanism is located outside the storage space. Figure 3 A second schematic diagram of the feeding process of the feeding mechanism provided in some embodiments of the present application, wherein the bottom loading mechanism is located in the storage space, and the feeding assembly is located at one of the feeding positions. Figure 4 A third process diagram of feeding of a feeding mechanism provided in some embodiments of the present application, wherein a material cart is transferred to a feeding assembly. Figure 5 A fourth process diagram of feeding of a feeding mechanism provided in some embodiments of the present application, wherein the feeding component is located at a material picking position.

[0050] The feeding mechanism includes: a frame 100, a plurality of feeding mechanisms 200, a lifting device 300, a feeding assembly 400 and a plurality of material carts 500.

[0051] Among them, multiple groups of feeding mechanisms 200 are movably arranged on the frame 100. The feeding assembly 400 has a material taking position for external material taking and multiple feeding positions. The lifting device 300 is used to drive the feeding assembly 400 to switch between the material taking position and the multiple feeding positions. Multiple material carts 500 are respectively arranged on the corresponding feeding mechanisms 200.

[0052] When the feeding assembly 400 is at the corresponding feeding position, the material trolley 500 can be transferred from the corresponding loading mechanism 200 to the feeding assembly 400 .

[0053] In this way, during the production process, the feeding assembly 400 can reach feeding positions at different heights through the lifting device 300, thereby facilitating the transfer of the material carts 500 on different loading mechanisms 200 to the feeding assembly 400, thereby realizing multi-position loading; since the material picking position of the feeding assembly 400 is at a fixed height, the mechanical arm can uniformly pick up materials at the material picking positions at the same height, thereby eliminating the need to design complex mechanism deformation, reducing costs, and avoiding the space requirements of the mechanical arm during the deformation process, thereby allowing the matching feeding mechanism to be used in a small plot space.

[0054] Specifically, the rack 100 may include multiple storage spaces 110 for storing materials. The multiple storage spaces 110 are usually stacked along the height direction Z to improve space utilization efficiency. Each layer of storage space 110 forms a first opening 111 and a second opening 112 on both sides of the rack 100 along the thickness direction X.

[0055] The loading mechanism 200 corresponds to the storage space 110 one by one; each group of loading mechanisms 200 is movably arranged in the corresponding storage space 110 for transferring materials. The loading mechanism 200 can extend from the first opening 111 of the storage space 110 to the outside of the storage space 110; thus, it is convenient for operators to load and unload materials on the loading mechanism 200 outside the storage space 110; for example, transferring a fully loaded material trolley 500 to the loading mechanism 200, or unloading an empty material trolley 500 from the loading mechanism 200.

[0056] The feeding assembly 400 is arranged on one side of the frame 100 in the thickness direction close to the second opening 112. The feeding assembly 400 may have a material taking position for external material taking and multiple feeding positions. Specifically, the material taking position may be located at the top, the bottom, or the middle area along the height direction Z, as long as it is convenient for the external mechanical arm to grab the material. In the embodiment of the present application, for the convenience of description, the material taking position is defined as the top of the frame 100 along the height direction Z; the multiple feeding positions correspond to the second openings 112 of the multiple storage spaces 110 respectively; that is, the height of the feeding position of the feeding assembly 400 is the same or approximately equal to the height of the corresponding second opening 112, and each feeding position corresponds to the second opening 112 of the storage space 110 one by one.

[0057] Multiple material carts 500 correspond one-to-one to multiple loading mechanisms 200, and each material cart 500 is respectively arranged on the corresponding loading mechanism 200; when the feeding component 400 is in the corresponding feeding position, the material cart 500 can be transferred from the second opening 112 corresponding to the storage space 110 to the feeding component 400.

[0058] The lifting device 300 can be arranged on one side of the frame 100 close to the second opening 112; the lifting device 300 is transmission-connected with the feeding assembly 400 to drive the feeding assembly 400 to switch between the material taking position and a plurality of feeding positions.

[0059] The work production process is as follows: First, combine Figure 2 As shown, the operator performs a loading operation on the bottom loading mechanism 200 in a side space near the second opening 111, that is, places the material trolley 500 with arranged materials on the bottom loading mechanism 200; then, in combination with Figure 3 and Figure 4As shown, the operator pushes the feeding mechanism 200 of the bottom layer back to the corresponding storage space 110 of the bottom layer, and the lifting device 300 drives the feeding assembly 400 to descend to the corresponding feeding position of the bottom layer, and the material trolley 500 can be transferred from the second opening 112 corresponding to the storage space 110 to the feeding assembly 400 to complete the material transfer; finally, combined with Figure 5 As shown, the lifting device 300 drives the feeding assembly 400 to rise from the feeding position on the bottom layer to the picking position, so that the material cart 500 on the feeding assembly 400 can be picked up by an external mechanical arm at the picking position, thereby completing the material transfer between the loading mechanism 200 and the feeding assembly 400 and the production process such as picking and loading materials.

[0060] During continuous production, the operator continues to place the material cart 500 with arranged materials on the loading mechanism 200 of the second layer; then, the operator pushes the loading mechanism 200 of the second layer back to the corresponding storage space 110 of the second layer, and the lifting device 300 drives the feeding assembly 400 carrying the bottom material cart 500 to descend to the feeding position of the bottom layer, and the material cart 500 is transferred from the feeding assembly 400 to the loading mechanism 200 located in the storage space 110 of the bottom layer in the reverse direction, so as to facilitate the subsequent operators to load the loading mechanism 200 of the bottom layer. material operation; then, the unloaded feeding assembly 400 is driven by the lifting device 300 to transfer from the feeding position of the bottom layer to the feeding position of the second layer, and the material trolley 500 on the second layer loading mechanism 200 can be transferred from the second opening 112 corresponding to the second layer storage space 110 to the feeding assembly 400; finally, the lifting device 300 drives the feeding assembly 400 to rise from the feeding position of the second layer to the picking position, so that the external mechanical arm can pick up the material trolley 500 on the feeding assembly 400 at the picking position to complete the production process.

[0061] Similarly, the process of taking materials from the third-layer feeding position and the fourth-layer feeding position is similar to the above process and will not be repeated here. In this way, it is possible to realize the production process of loading materials at multiple positions of the material cart and fixing it at the material taking position through the mechanical arm. In addition, since the mechanical arm does not need to design complex mechanism deformation, the structure is simple and can effectively reduce costs, and it also avoids the space requirements of the mechanical arm, and ultimately the matching feeding mechanism can be used in small plots of space, expanding the scope of application scenarios of the feeding mechanism.

[0064] Among them, the top plate 160 is arranged opposite to the bottom plate 140, and the left vertical plate 120 and the right vertical plate 130 are arranged opposite to each other and supported between the bottom plate 140 and the top plate 160; the bottom plate 140, the top plate 160, the left vertical plate 120 and the right vertical plate 130 can all be metal plates, on which metal rods for increasing strength can be arranged, so that the frame 100 can serve as a basic bearing structure.

[0065] The crossbar 150 may be a metal rod. A plurality of crossbars 150 are connected between the left vertical plate 120 and the right vertical plate 130 to separate the storage space 110 , thereby facilitating the placement of the loading mechanism 200 in the storage space 110 .

[0066] Optionally, the rack 100 includes an outer cover and a plurality of U-shaped connections. The outer cover is usually a hollow cover shell of plastic or metal, and the outer cover can be covered on the outside of the left vertical plate 120 / right vertical plate 130 through a U-shaped connector to prevent dust and debris. The U-shaped connector can be connected to the left vertical plate 120 / right vertical plate 130 by bolts or welding.

[0068] In some embodiments of the present application, see Figures 6 to 8 As shown, the frame 100 includes a plurality of locking blocks 180. Specifically, the locking block 180 may be an L-shaped metal block having a first latch hole (not shown); the locking block 180 is set on the left vertical plate 120 or the right vertical plate 130 by bolts, and each storage space 110 has at least one locking block 180 to facilitate fixed connection with the feeding mechanism 200.

[0069] The feeding mechanism 200 includes a first latch 250 and a first driver 251 for driving the first latch 250. When the feeding mechanism 200 is located in the corresponding storage space 110, the first driver 251 can drive the first latch 250 to insert into the first latch through hole of the locking block 180.

[0070] The first driver 251 can be designed as a cylinder or an electric motor as needed, which is not limited in the embodiment of the present application.

[0071] When the loading mechanism 200 is located in the corresponding storage space 110, the first driver 251 drives the first latch 250 to move up and down along the height direction Z, so that the first latch 250 is inserted into the latch through hole to lock the storage space 110 and the loading mechanism 200, thereby facilitating the transfer of the material cart 500 from the loading mechanism 200 to the feeding assembly 400. In addition, it can also prevent the loading mechanism 200 from sliding out of the first opening 111 of the storage space 110 when transferring materials at the loading mechanism 200 on other layers, thereby avoiding affecting work efficiency.

[0072] Optionally, the cylinder body of the first driver 251 can be fixedly connected to the second slide bar 222 (mentioned below) of the feeding mechanism 200 via an L-shaped fixing member 253, the telescopic rod of the first driver 251 is connected to the first latch 250, and the first latch 250 can be guided by a guide block 252 to prevent deflection.

[0073] In some embodiments of the present application, the rack 100 includes a plurality of third drivers 190 and a plurality of third latches 170; the plurality of third drivers 190 are respectively disposed on the left vertical plate 120 or the right vertical plate 130 and are located on a side close to the second opening 112, and the third latches 170 are transmission-connected to the third drivers 190;

[0074] The third driver 190 can be designed as a cylinder or an electric motor as needed, which is not limited in the embodiment of the present application.

[0075] In addition to the storage space 110 at the bottom layer, the storage space 110 at the second layer and the storage space 110 at the third layer may correspond to at least one third driver 190 and one third latch 170, so as to facilitate the fixed connection with the feeding assembly 400 and realize the locking of the lifting mechanism. Specifically, when the feeding assembly 400 is in the corresponding feeding position, the third driver 190 drives the third latch 170 to extend along the thickness direction X, and is positioned and embedded in the groove 411 on the support frame 410 (mentioned below) on the feeding assembly 400, so as to realize the fixed limit along the height direction Z, thereby preventing the lifting device 300 from falling due to unstable air pressure, causing the feeding assembly 400 to fall.

[0076] In some embodiments of the present application, see Figures 1 to 7 As shown, the feeding mechanism 200 includes two sets of slide rails 210 , two sets of sliding rods 220 , a door panel 230 , a hook 240 and a horizontal push driving member 241 .

[0077] In a set of feeding mechanism 200, two sets of slide rails 210 are arranged opposite to each other, the two sets of slide rails 210 are in the corresponding storage space 110, and are respectively fixed on the left vertical plate 120 and the right vertical plate 130; the slide rails 210 and the left vertical plate 120, and the slide rails 210 and the right vertical plate 130 can usually be connected by screws or welding. Two sets of sliding rods 220 are respectively slidably arranged on the two sets of slide rails 210; the door panels 230 are erected at the ends of the two sets of slide rails 210, and the whole is in a U shape.

[0078] The hook 240 is movably arranged on the side of the door panel 230 facing the first opening 111; when the feeding mechanism 200 is located in the corresponding storage space 110, the door panel 230 covers the first opening 111, thereby closing the storage space 110 to avoid external interference.

[0079] The push driving member 241 may be a cylinder or an electric motor, which is not limited in the present application.

[0080] The horizontal push driving member 241 is disposed on the door panel 230 to drive the hook 240 to move horizontally. Figure 1 , Figure 2 , Figure 7 and Fig. 9 As shown, when the loading operation is performed on the loading mechanism 200 of the bottom layer in the side space close to the second opening 111, the push drive member 241 pushes the hook 240 to move horizontally to the left for a distance, so as to facilitate the connection between the hook 240 and the connecting part 540 (mentioned below) on the material trolley 500, thereby achieving the fixation of the loading mechanism 200 and the material trolley 500 and avoiding the position displacement of the material trolley 500 when the loading mechanism 200 enters and exits the storage space 110.

[0081] Combination Figure 1 , Figure 3 , Figure 7 and Fig. 9 As shown, the operator pushes the loading mechanism 200 on the bottom layer back to the corresponding storage space 110, and the lifting device 300 drives the feeding assembly 400 to descend to the corresponding feeding position; at this time, the push drive member 241 pulls the hook 240 to move horizontally to the right for a distance, so as to facilitate the separation of the hook 240 from the connecting part 540 on the material cart 500, and the loading mechanism 200 is separated from the material cart 500; the material cart 500 can be transferred from the second opening 112 corresponding to the storage space 110 to the feeding assembly 400, thereby completing the transfer of materials.

[0082] In some embodiments of the present application, see Figures 1 to 7As shown, the sliding rod 220 includes a first sliding rod 221 and a second sliding rod 222. The first sliding rod 221 is slidably disposed on the slide rail 210, and the second sliding rod 222 is slidably connected to the first sliding rod 221. The door panel 230 stands on one end of the second sliding rod 222 away from the first sliding rod 221. The two-stage first sliding rod 221 and the second sliding rod 222 increase the range of motion of the feeding mechanism 200, making it convenient to place the material trolley 500 with arranged materials on the bottom feeding mechanism 200, so that the operator can have more space to operate, thereby improving the feeding efficiency.

[0083] In some embodiments of the present application, see Figures 1 to 9 As shown, the material cart 500 includes a carrying plate 510 , a placement frame 520 , rolling wheels 530 and a hooking portion 540 .

[0084] The supporting plate 510 can be designed as a plate structure of regular shapes such as square and circle, and its material can be selected from aluminum alloy, carbon steel, stainless steel and other materials, which has the advantages of low cost and good strength.

[0085] The rolling wheels 530 are supported on the bottom surface of the carrier plate 510 to reduce friction. The rolling wheels 530 can be rubber rollers; there are usually 4 to 12 rolling wheels 530, which are divided into two rows and arranged on both sides of the bottom surface of the carrier plate 510, and can be designed and adjusted accordingly according to the load-bearing weight of the carrier plate 510. Each row of rolling wheels 530 is rotatably arranged on the second slide bar 222, and can roll forward and backward along the thickness direction X, reducing friction, so that the material cart 500 can move forward and backward smoothly.

[0086] The placement rack 520 is disposed on the top surface of the carrier plate 510 for fixing materials. The placement rack 520 can generally be a plastic injection molded part, which is formed with grooves for fixing materials, and the specific design shall prevail. The placement rack 520 can be detachably connected to the carrier plate 510, such as bolted connection, to facilitate replacement and maintenance.

[0087] The hooking portion 540 is disposed at one end of the carrying plate 510 close to the door panel 230 ; the hooking portion 540 can be hooked with the hook 240 at a predetermined position.

[0088] Optionally, the hooking portion 540 may be a rod, which is directly hooked with the hook 240 through the rod. Optionally, the hooking portion 540 may include a movable block formed with a groove, and when the hook 240 is driven by the horizontal push driving member 241 to move to the left to reach a predetermined position, the hook 240 can be engaged with the groove to achieve connection. The hooking portion 540 may also be a latch and a driver, and a connection hole matching the hook 240 is formed on the latch, and the driver drives the latch to move to hook with the hook 240.

[0089] In some embodiments of the present application, see Fig. 9 As shown, the material trolley 500 includes a sensor 550, which is arranged on the supporting plate 510 for detecting materials, thereby realizing automatic management and avoiding abnormal situations such as material shortage, leakage or skewed material feeding.

[0090] Specifically, the sensor 550 can be a photoelectric sensor, a pressure sensor or other sensors. The sensor 550 is mainly arranged on the top surface of the carrier plate 510. There can be multiple sensors 550 on each material trolley 500. Some sensors 550 can be used to detect the quantity of materials on the placement rack 520, and can directly send a refill signal when there is a shortage of materials; another part of the sensors 550 can detect the position deviation of the material, and send an alarm signal when the position of the material is deflected, so as to prevent the external mechanical arm from grasping in the wrong position, causing grasping failure or unqualified grasping accuracy.

[0091] In some embodiments of the present application, see Figure 1 and Fig.10 As shown, the lifting device 300 includes a lifting drive 310, a fixed base 320, a slide rail connecting block 330, a connecting rod 340 and a guide rail 350; the guide rail 350 is arranged on the area of ​​the right vertical plate 130 close to the second opening 112 and extends along the height direction Z, the slide rail connecting block 330 is slidably arranged on the guide rail 350, and the slide rail connecting block 330 is fixedly connected to the feeding assembly 400.

[0092] The lifting drive member 310 may be a cylinder or an electric motor, which is not limited in the present application.

[0093] The cylinder body of the lifting drive member 310 is fixedly connected to the base plate 140 through the fixed base 320, and the piston rod of the lifting drive member 310 is connected to the slide rail connecting block 330 through the connecting rod 340 to drive the slide rail connecting block 330 to rise and fall; in this way, the lifting device 300 can drive the feeding assembly 400 to lift and switch between the material picking position and multiple feeding positions, thereby completing functions such as material loading and transfer.

[0094] In some embodiments of the present application, see Figure 1 and Fig.10 As shown, the lifting device 300 includes a buffer 360, which is arranged on the slide rail connecting block 330. The buffer 360 can be a spring; when the lifting device 300 drives the feeding assembly 400 to lift and switch between the material taking position and multiple feeding positions, the buffer 360 can absorb vibration and extend the service life.

[0095] In some embodiments of the present application, see Figure 1 and Fig.11 As shown, the feeding assembly 400 includes a support frame 410 , a push-pull assembly 420 and a locking member 430 .

[0096] Among them, the support frame 410 can be an L-shaped frame formed by overlapping multiple rods, and the strength can be improved by adding ribs to the L-shaped frame. The material of the rod can be aluminum alloy, stainless steel or carbon steel, or ABS plastic, which is not limited in the embodiment of the present application.

[0097] The support frame 410 is fixedly connected to the slide rail connecting block 330; the push-pull assembly 420 is arranged on the support frame 410 and is used to push and pull the material trolley 500 to realize the switching of the material trolley 500 between the loading mechanism 200 and the feeding assembly 400; the locking member 430 is arranged on the support frame 410, and when the material trolley 500 is on the feeding assembly 400, the locking member 430 can fix the material trolley 500.

[0098] Specifically, combined Figure 3 to Figure 4 , Figures 9 to 11 As shown, the operator pushes the bottom loading mechanism 200 back to the corresponding storage space 110 of the bottom layer, and the lifting device 300 drives the feeding assembly 400 to descend to the corresponding feeding position of the bottom layer; the horizontal push drive member 241 pulls the hook 240 to move horizontally to the right for a distance, so as to facilitate the separation of the hook 240 from the hooking part 540 on the material cart 500, and the loading mechanism 200 is separated from the material cart 500, and the push-pull assembly 420 pushes and pulls the material cart 500, so that the material cart 500 can be transferred from the second opening 112 corresponding to the storage space 110 to the feeding assembly 400, and finally the material cart 500 is locked with the support frame 410 by the locking member 430, so as to achieve relative fixation of the material cart 500 and the feeding assembly 400, and complete the material transfer. Figure 5 As shown, the lifting device 300 drives the feeding assembly 400 to rise from the feeding position on the bottom layer to the picking position. At this time, the locking member 430 remains locked to prevent the material cart 500 and the feeding assembly 400 from relative displacement, making it convenient for the external mechanical arm to pick up the material cart 500 on the feeding assembly 400 at the picking position, thereby completing the material production process.

[0099] In some embodiments of the present application, see Figure 1 and Fig.11 As shown, the feeding assembly 400 includes a roller guide bar 450, which is disposed on the support frame 410 and extends to a side close to the second opening 112 along the thickness direction X. In this way, the roller guide bar 450 provides guidance to the rolling wheel 530, ensuring that the material trolley 500 can be smoothly transferred from the second opening 112 corresponding to the storage space 110 to the feeding assembly 400.

[0100] Optionally, there may be two roller guide bars 450 , which are arranged opposite to each other on the support frame 410 .

[0101] In some embodiments of the present application, see Fig.10 As shown, the locking member 430 includes a second latch 431 and a second driver 432; along the height direction Z, the second latch 431 is telescopically arranged on the support frame 410, and the second driver 432 is drivingly connected to the second latch 431. A positioning hole (not marked) adapted to the second latch 431 is arranged on the carrying plate 510 of the material trolley 500.

[0102] The second driver 432 can be designed as a cylinder or an electric motor as needed, which is not limited in the embodiment of the present application.

[0103] Combination Figure 1 , Figure 4 , Figures 9 to 11 As shown, the material cart 500 is transferred from the second opening 112 corresponding to the storage space 110 to the feeding assembly 400; the second driver 432 drives the second latch 431 to extend from bottom to top and insert into the positioning hole of the supporting plate 510, so that the relative position of the material cart 500 and the support frame 410 can be locked, and the relative fixation of the material cart 500 and the feeding assembly 400 can be achieved. During the lifting process of the feeding assembly 400, the relative displacement of the material cart 500 and the feeding assembly 400 can be effectively avoided, so that the external mechanical arm can pick up the material cart 500 on the feeding assembly 400 at the picking position, and finally complete the material production process.

[0104] In some embodiments of the present application, see Figure 1 and Fig.11 As shown, the push-pull assembly 420 includes a first push-pull driving member 421, a second push-pull driving member 422, a transition block 423, a fixing plate 424, a connecting plate 425, a push-pull block 426 and a connecting shaft 427. The cylinder of the first push-pull driving member 421 is fixedly connected to the support frame 410 through the fixing plate 424. Specifically, the fixing plate 424 is fixedly connected to the support frame 410 through bolts, and the cylinder of the first push-pull driving member 421 is arranged on the fixing plate 424.

[0105] The telescopic rod of the first push-pull driving member 421 is fixedly connected to the connecting plate 425 through the transition block 423; the cylinder body of the second push-pull driving member 422 is set on the connecting plate 425, the telescopic rod of the second push-pull driving member 422 is fixedly connected to the push-pull block 426, and the connecting shaft 427 is fixed on the push-pull block 426.

[0106] The first push-pull driving member 421 and the second push-pull driving member 422 may be cylinders or electric motors, which is not limited in the present application.

[0107] It can be understood that due to the provision of the first push-pull drive member 421 and the second push-pull drive member 422, the material cart 500 is pushed and pulled in two stages in the thickness direction X, thereby achieving long-distance pushing and pulling, reducing the requirements for a single push-pull drive member, reducing costs, and making the structure more stable and reliable.

[0108] Combination Figure 1 , Figure 3 , Figure 4 , Figure 7 , Fig. 9 , Fig.11 as well as Fig.12 As shown, the operator pushes the feeding mechanism 200 of the bottom layer back to the corresponding storage space 110, and the lifting device 300 drives the feeding assembly 400 to descend to the corresponding feeding position; at this time, the horizontal push driving member 241 pulls the hook 240 to move horizontally to the right for a distance, so that the hook 240 is separated from the hooking part 540 on the material trolley 500, and the feeding mechanism 200 is separated from the material trolley 500; the first push-pull driving member 421 and the second push-pull driving member 422 are pushed out in sequence to make the connection The shaft 427 can be hooked with the hooking part 540, thereby retracting the first push-pull driving member 421 and the second push-pull driving member 422 in turn, driving the push-pull block 426 and the connecting shaft 427 to retract, thereby pulling the material cart 500 out from the second opening 112 corresponding to the storage space 110, and providing guidance to the rolling wheel 530 through the roller guide bar 450 set on the support frame 410, ensuring that the material cart 500 can be smoothly transferred to the feeding assembly 400 to complete the material transfer.

[0109] A second aspect of an embodiment of the present application provides a battery production system, including the above-mentioned feeding mechanism.

[0110] The battery production system can be applied to the production and testing of batteries, battery cells and other products. The feeding mechanism can provide storage, loading, unloading and material transfer functions for finished and semi-finished products of batteries and battery cells.

[0111] It is understandable that the battery production system may further include a mechanical arm for taking materials from the material taking position of the feeding mechanism to complete the material transfer. The mechanical arm may be a fixed-point moving pneumatic gripper or a deformable multi-axis mechanical arm, which is subject to the specific design.

[0112] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0113] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
