Description

Technical Field

[0001] This invention relates to the field of material storage technology, and more particularly to a material storage mechanism. Background Technology

[0002] In the automated formation process of battery cells using formation equipment, a buffer mechanism is required to buffer and store the cells, which facilitates the loading and unloading of the formation equipment. However, with the development of existing automated equipment and the gradual increase in loading and unloading speeds and automated operation speeds, the buffer mechanism can no longer keep up with the speed of automated operation. This leads to excessively long waiting times for cells on the production line, causing the entire line to stop, resulting in inefficiency and wasted costs. Furthermore, existing buffer mechanisms have limited storage capacity; when the production line malfunctions and stops, a large accumulation of cells can occur in certain areas, a situation that the buffer mechanism with insufficient storage capacity cannot handle. Summary of the Invention

[0003] To overcome at least one of the defects described in the prior art, the present invention provides a material storage mechanism. By employing a first conveyor plate, a second conveyor plate, a loading conveyor plate, and a unloading conveyor plate to load and unload battery cells onto the material trays, as well as to stack and disperse the material trays, the storage capacity of battery cells can be increased, thereby meeting the material conveying requirements of high-speed production lines and avoiding the phenomenon of stopping the entire production line.

[0004] The technical solution adopted by this invention to solve its problem is:

[0005] A material storage mechanism includes a first conveying disc, a second conveying disc, a feeding conveying disc, a discharging conveying disc, and a plurality of material trays; a first transmission mechanism for conveying material trays is provided between the first conveying disc and the second conveying disc; a second transmission mechanism for conveying material trays is provided between the feeding conveying disc and the discharging conveying disc; a first lifting mechanism for conveying material trays is provided between the first conveying disc and the feeding conveying disc; a second lifting mechanism for conveying material trays is provided between the second conveying disc and the discharging conveying disc; wherein, a first material distribution mechanism is provided on the first conveying disc, a first material stacking mechanism is provided on the second conveying disc, a second material stacking mechanism is provided on the feeding conveying disc, and a second material distribution mechanism is provided on the discharging conveying disc; the first material stacking mechanism, the second material stacking mechanism, the first material distribution mechanism, and the second material distribution mechanism operate synchronously.

[0006] By adopting the above scheme, the battery cells can be loaded from the loading conveyor. After loading, the trays are stacked and then conveyed to the unloading conveyor via the second transmission mechanism. The batteries on the trays are then unloaded layer by layer. After unloading, the trays are sent to the second conveyor via the second lifting mechanism for stacking. Then, they are conveyed to the first conveyor via the first transmission mechanism. The empty trays are sent out layer by layer and transported to the loading conveyor via the first lifting mechanism for loading. This enables continuous material supply to the production line and avoids stopping the entire line.

[0007] Furthermore, both the first and second stacking mechanisms include: stacking baffles, with a set of opposing stacking baffles provided on both sides of the first and second stacking mechanisms, forming a stacking space between the stacking baffles; a stacking lifting cylinder, which is mounted below the first and second stacking mechanisms to lift at least one of the material trays along the stacking space; and a stacking blocking cylinder, which is mounted on the stacking baffles to support at least one material tray lifted by the stacking lifting cylinder.

[0008] By adopting the above scheme and setting up a stacking space, the material trays can be stacked from the bottom of the stacking space in cooperation with the stacking lifting cylinder and the stacking blocking cylinder, thereby achieving the material storage effect.

[0009] Furthermore, the first and second material dispensing mechanisms include: material dispensing baffles, with a set of opposing material dispensing baffles provided on both sides of the first and second material dispensing mechanisms, forming a material dispensing space between the material dispensing baffles; a material dispensing lifting cylinder, which is mounted below the first and second material dispensing mechanisms to lift at least one of the material trays along the material dispensing space; and a material dispensing blocking cylinder, which is mounted on the material dispensing baffles to support the remaining material trays except for the bottom layer.

[0010] By adopting the above scheme and setting up a material distribution space, the material tray can be dispersed from the bottom of the material distribution space with the cooperation of the material distribution lifting cylinder and the material distribution blocking cylinder, thereby achieving the effect of layer-by-layer material distribution.

[0011] Furthermore, both the first conveyor plate and the second conveyor plate include: a first coaxial conveyor belt mechanism that drives two first conveyor belts; a first pull wire device that connects to the two first conveyor belts respectively and moves with the two first conveyor belts; and a first conveyor drive motor that drives the first coaxial conveyor belt mechanism to rotate.

[0012] By adopting the above scheme, the function of transporting material trays through the first pull wire device can be realized, which helps to stack or disperse the material trays.

[0013] Furthermore, both the loading conveyor and the unloading conveyor include: a second coaxial conveyor belt mechanism that drives two second conveyor belts; a second wire pulling device that connects to the two second conveyor belts respectively and moves with the two second conveyor belts; and a second conveyor drive motor that drives the second coaxial conveyor belt mechanism to rotate.

[0014] By adopting the above scheme, the function of transporting material trays through the second pull wire device can be realized, which helps to stack or disperse the material trays.

[0015] Furthermore, the first conveyor plate, the second conveyor plate, the loading conveyor plate, and the unloading conveyor plate are all equipped with clamping cylinders to clamp the material plate and move it toward the first lifting mechanism or the second lifting mechanism.

[0016] By adopting the above solution, the material tray can be moved towards the first lifting mechanism or the second lifting mechanism by the clamping cylinder, thereby realizing the lifting and transportation of the material tray.

[0017] Furthermore, both the first lifting mechanism and the second lifting mechanism include: a lifting base plate; a lifting frame, the lifting frame being vertically mounted on the lifting base plate; a lifting conveyor belt, the lifting conveyor belt being longitudinally slidable on the lifting frame; and a lifting motor, the lifting motor driving the lifting conveyor belt to perform linear reciprocating motion.

[0018] By adopting the above scheme, the material tray can be lifted and moved up and down by raising the material plate, thereby realizing the transfer and transportation of the material tray.

[0019] Furthermore, the first transmission mechanism and the second transmission mechanism include a roller frame and a plurality of rollers, the rollers being sequentially arranged and assembled between the roller frame.

[0020] By adopting the above method, it is easier to transfer stacked trays.

[0021] Furthermore, the first transmission mechanism is provided with a first steering mechanism at both ends, and the second transmission mechanism is provided with a second steering mechanism at both ends.

[0022] By adopting the above scheme, the stacked material trays can be transferred and transported in conjunction with the first transmission mechanism and the second transmission mechanism.

[0023] Further, the first steering mechanism and the second steering mechanism include: a steering mechanism base; a timing belt, which is mounted above the steering mechanism base; a steering motor, which drives the timing belt to rotate; and a steering mechanism lifting cylinder, which is mounted with the steering mechanism base to lift the steering mechanism base.

[0024] By adopting the above scheme, the base of the steering mechanism is lifted by the lifting cylinder of the steering mechanism, so that the synchronous belt contacts the bottom of the stacked material tray, thereby giving the material tray traction force, which allows the material tray to move on the first transmission mechanism or the second transmission mechanism.

[0025] Furthermore, it also includes an upper frame and a lower frame, with the feeding conveyor and the unloading conveyor assembled on the upper frame, and the first conveyor and the second conveyor assembled on the lower frame.

[0026] By adopting the above scheme, the first conveyor plate, the second conveyor plate, the feeding conveyor plate, and the unloading conveyor plate can be divided into upper and lower layers, reducing the overall footprint of the storage mechanism.

[0027] In summary, the material storage mechanism provided by the present invention has the following technical effects:

[0028] 1. It can stack and disperse the material trays storing battery cells, as well as stack and disperse the empty material trays, meeting the material tray supply requirements for loading and unloading of high-speed production lines, and preventing the high-speed production line from stopping to wait for material trays.

[0029] 2. Because the storage mechanism can stack a large number of trays, there is no need to stop the operation of other mechanisms when a small problem occurs on the high-speed production line, so it can store materials in time and has a strong emergency response capability.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] See Embodiment 1 of the present invention. Figures 1-3 As shown, a material storage mechanism is disclosed, including a first conveyor plate 1, a second conveyor plate 2, a feeding conveyor plate 3, a discharging conveyor plate 4, several material trays 5, an upper frame 20, and a lower frame 30. The feeding conveyor plate 3 and the discharging conveyor plate 4 are assembled on the upper frame 20, and the first conveyor plate 1 and the second conveyor plate 2 are assembled on the lower frame 30. The material trays 5 circulate among the first conveyor plate 1, the second conveyor plate 2, the feeding conveyor plate 3, and the discharging conveyor plate 4 to complete the feeding, discharging, and storage functions. By dividing the first conveyor plate 1, the second conveyor plate 2, the feeding conveyor plate 3, and the discharging conveyor plate 4 into upper and lower layers, the overall footprint of the material storage mechanism can be reduced, and the upper layer can store material trays 5, while the lower layer stores empty material trays 5.

[0039] Specifically, both the first conveyor tray 1 and the second conveyor tray 2 include a first coaxial conveyor belt mechanism 11, a first wire pulling device 12, and a first conveyor drive motor 13. The first coaxial conveyor belt mechanism 11 drives two first conveyor belts. The first wire pulling device 12 is connected to the two first conveyor belts respectively and moves with the two first conveyor belts. The first conveyor drive motor 13 drives the first coaxial conveyor belt mechanism 11 to rotate, thus realizing the function of transporting the material tray 5 through the first wire pulling device 12. Both the loading conveyor tray 3 and the unloading conveyor tray 4 include a second coaxial conveyor belt mechanism 31, a second wire pulling device 32, and a second conveyor drive motor 33. The second coaxial conveyor belt mechanism 31 drives two second conveyor belts 311. The second wire pulling device 32 is connected to the two second conveyor belts 311 respectively and moves with the two second conveyor belts 311. The second conveyor drive motor 33 drives the second coaxial conveyor belt mechanism 31 to rotate, thus realizing the function of transporting the material tray 5 through the second wire pulling device 32.

[0040] To improve the storage capacity of the storage mechanism, in this embodiment 1, a first material distribution mechanism 14 is provided on the first conveyor plate 1, a first material stacking mechanism 21 is provided on the second conveyor plate 2, a second material stacking mechanism 34 is provided on the feeding conveyor plate 3, and a second material distribution mechanism 41 is provided on the unloading conveyor plate 4. The first material stacking mechanism 21, the second material stacking mechanism 34, the first material distribution mechanism 14, and the second material distribution mechanism 41 operate synchronously. Both the first material stacking mechanism 21 and the second material stacking mechanism 34 include a material stacking baffle 341, a material stacking lifting cylinder 342, and a material stacking blocking cylinder 343. The two sides of the first material stacking mechanism 21 and the... A set of opposing stacking baffles 341 are provided on both sides of the second stacking mechanism 34, forming a stacking space 22 between the stacking baffles. The stacking lifting cylinder 342 is mounted below the first stacking mechanism 21 and the second stacking mechanism 34 to lift at least one of the material trays 5 along the stacking space 22. The stacking blocking cylinder 343 is mounted on the stacking baffles 341 to support at least one material tray 5 lifted by the stacking lifting cylinder 342. By setting up the stacking space 22, the material trays 5 can be stacked from the bottom of the stacking space 22 with the cooperation of the stacking lifting cylinder 342 and the stacking blocking cylinder 343, thereby achieving the material storage effect.

[0041] See Figure 1-3As shown, when the empty material tray 5 reaches the feeding conveyor tray 3, the material tray 5 begins to be fed. After the battery cell is placed into the material tray 5, the second wire pulling device 32 of the feeding conveyor tray 3 pulls the material tray 5 towards the second stacking mechanism 34. If there is no material tray 5 in the stacking space 22 of the second stacking mechanism 34 at this time, the material tray 5 directly enters the stacking space 22. Before the subsequent material tray 5 arrives at the stacking space 22, the stacking lifting cylinder 342 lifts the material tray 5 in the stacking space 22. At this time, the stacking blocking cylinder 34... 3. The stacking lifting cylinder 342 supports the material tray 5 that has been lifted by the stacking cylinder. At this time, the stacking lifting cylinder 342 is reset, and subsequent material trays 5 can be directly stacked from the bottom of the stacking space 22 until the stacking height of the material trays 5 reaches the maximum limit of the stacking space 22. Then, the first pull wire device 12 drives the stacked material trays 5 in the stacking space 22 to continue forward, realizing the transfer of the material trays 5 with full cells. At this time, the material trays 5 inside the stacking space 22 are emptied, and a new round of stacking can be realized. When the empty pallet 5 reaches the second conveyor plate 2, the first pull wire device 12 on the second conveyor plate 2 pulls the pallet 5 toward the first stacking mechanism 21. If there is no pallet 5 in the stacking space 22 of the first stacking mechanism 21 at this time, the pallet 5 directly enters the stacking space 22. Before the subsequent pallet 5 reaches the stacking space 22, the stacking lifting cylinder 342 lifts the pallet 5 in the stacking space 22. At this time, the stacking blocking cylinder 343 works to support the pallet 5 lifted by the stacking lifting cylinder 342. At this time, the stacking lifting cylinder 342 resets, and the subsequent pallets 5 can be stacked directly from the bottom of the stacking space 22 until the stacking height of the pallets 5 reaches the maximum limit of the stacking space 22. Then, the first pull wire device 12 drives the stacked pallets 5 in the stacking space 22 to continue forward, realizing the transfer of the empty pallet 5. At this time, the pallets 5 inside the stacking space 22 are emptied, and a new round of stacking can be realized.

[0042] The first material distribution mechanism 14 and the second material distribution mechanism 41 include a material distribution baffle 141, a material distribution lifting cylinder 142, and a material distribution blocking cylinder 143. A set of opposing material distribution baffles 141 are provided on both sides of the first material distribution mechanism 14 and both sides of the second material distribution mechanism 41, forming a material distribution space 15 between the material distribution baffles 141. The material distribution lifting cylinder 142 is mounted below the first material distribution mechanism 14 and the second material distribution mechanism 41 to lift at least one of the material trays 5 along the material distribution space 15. The material distribution blocking cylinder 143 is mounted on the material distribution baffle 141 to support the remaining material trays 5 except for the bottom layer. By setting the material distribution space 15, the material trays 5 can be dispersed from the bottom of the material distribution space 15 with the cooperation of the material distribution lifting cylinder 142 and the material distribution blocking cylinder 143, thereby achieving the effect of layer-by-layer material distribution.

[0043] For details, please refer to Figure 1-3 As shown, when the stacked material trays 5 reach the unloading conveyor 4, the second pull wire device 32 of the unloading conveyor 4 pulls the material trays 5 towards the second distributing mechanism 41 until they move into the distributing space 15 within the second distributing mechanism 41. At this time, the distributing lifting cylinder 142 raises the stacked material trays 5 until the second to last material tray 5 in the stack is higher than the distributing blocking cylinder 143. At this time, the distributing blocking cylinder 143 works to support and lift the material trays 5 above the second to last material tray 5. At this time, the distributing lifting cylinder 142 resets and places the bottom material tray 5 on the second pull wire device 32 to be sent out of the distributing space 15 until all the material trays 5 in the distributing space 15 are sent out one by one. At this time, the next batch of stacked material trays 5 enters the distributing space 15. The material trays 5 that have been sent out become empty material trays 5 again after being unloaded, thus completing the unloading operation of the material trays 5 one by one. When the stacked empty trays 5 reach the first conveyor tray 1, the first pull wire device 12 of the first conveyor tray 1 pulls the trays 5 toward the first distributing mechanism 14 until they move into the distributing space 15 within the first distributing mechanism 14. At this time, the distributing lifting cylinder 142 raises the stacked trays 5 until the second-to-last tray 5 in the stack is higher than the distributing blocking cylinder 143. At this time, the distributing blocking cylinder 143 works to support and lift the trays 5 above the second-to-last tray 5. At this time, the distributing lifting cylinder 142 resets and places the bottom tray 5 on the second pull wire device 32 to be sent out of the distributing space 15 until all the trays 5 in the distributing space 15 are sent out one by one. At this time, the next batch of stacked empty trays 5 enters the distributing space 15, thus completing the operation of sending out the empty trays 5 one by one.

[0044] To achieve the transmission effect of the conveying tray 5 on the first conveying tray 1, the second conveying tray 2, the feeding conveying tray 3, and the unloading conveying tray 4, a first transmission mechanism 6 for conveying the conveying tray 5 is provided between the first conveying tray 1 and the second conveying tray 2, a second transmission mechanism 7 for conveying the conveying tray 5 is provided between the feeding conveying tray 3 and the unloading conveying tray 4, a first lifting mechanism 8 for conveying the conveying tray 5 is provided between the first conveying tray 1 and the feeding conveying tray 3, and a second lifting mechanism 9 for conveying the conveying tray 5 is provided between the second conveying tray 2 and the unloading conveying tray 4.

[0045] Specifically, in this embodiment 1, both the first lifting mechanism 8 and the second lifting mechanism 9 include a lifting base plate 81, a lifting frame 82, a lifting conveyor plate 83, and a lifting motor 84. The lifting frame 82 is vertically mounted on the lifting base plate 81, and the lifting conveyor plate 83 is longitudinally slidably mounted on the lifting frame 82. The lifting motor 84 drives the lifting conveyor plate 83 to perform linear reciprocating motion, thereby lifting and lowering the material tray 5 to achieve the transfer and transportation of the material tray 5. In some embodiments, to improve the stability of the material tray 5 transportation, clamping cylinders 10 are provided on the first conveyor plate 1, the second conveyor plate 2, the loading conveyor plate 3, and the unloading conveyor plate 4 to clamp the material tray 5 and move it toward the first lifting mechanism 8 or the second lifting mechanism 9. The clamping cylinders 10 can be used to move the material tray 5 toward the first lifting mechanism 8 or the second lifting mechanism 9, thereby achieving the lifting and transportation of the material tray 5.

[0046] In order to improve the stability of the first lifting mechanism 8 or the second lifting mechanism 9, in some embodiments, the bottom of the lifting frame 82 is also provided with a weight 85, which can improve the stability of its own lifting process.

[0047] In this embodiment 1, the first transmission mechanism 6 and the second transmission mechanism 7 include a roller frame 61 and a plurality of rollers 62. The rollers 62 are arranged sequentially between the roller frames 61, which is beneficial for transferring the stacked material trays 5. Since the rollers 62 only have the ability to passively roll the material trays 5, a first steering mechanism 23 is provided at both ends of the first transmission mechanism 6, and a second steering mechanism is provided at both ends of the second transmission mechanism 7, which can cooperate with the first transmission mechanism 6 and the second transmission mechanism 7 to transport the stacked material trays 5.

[0048] Specifically, the first steering mechanism 23 and the second steering mechanism include a steering mechanism base 231, a timing belt 232, a steering motor 233, and a steering mechanism lifting cylinder 234. The timing belt 232 is mounted above the steering mechanism base 231. The steering motor 233 drives the timing belt 232 to rotate. The steering mechanism lifting cylinder 234 is mounted with the steering mechanism base 231 to lift the steering mechanism base 231. By lifting the steering mechanism base 231 through the steering mechanism lifting cylinder 234, the timing belt 232 contacts the bottom of the stacking tray 5, thereby giving the tray 5 traction force, which allows the tray 5 to move on the first transmission mechanism 6 or the second transmission mechanism 7.

[0049] The overall workflow of this invention is as follows:

[0050] The empty material tray 5, positioned at the feeding position 35 of the feeding conveyor 3, feeds the battery cells from the production line, transforming the empty tray 5 into a material tray 5. The material tray 5, driven by the second wire pulling device 32 or the clamping cylinder 10 of the feeding conveyor 3, moves towards the second stacking mechanism 34. After being stacked by the second stacking mechanism 34, the second wire pulling device 32 drives the stacked material tray 5 to the first steering mechanism 23. In the first steering mechanism 23, the steering mechanism lifting cylinder 234 lifts the steering mechanism base 231, allowing the synchronous belt 23 to... 2. Upon contact with the bottom of the stacking tray 5, the stacked tray 5 is driven onto the roller 62 of the first transmission mechanism 6. Then, driven by the first steering mechanism 23 at the other end of the first transmission mechanism 6, the stacked tray 5 reaches the unloading conveyor 4. The stacked tray 5 is then moved towards the second distributing mechanism 41 by the second pull wire device 32 of the unloading conveyor 4. After being separated by the second distributing mechanism 41, the individual trays 5 are driven by the second pull wire device 32 or the clamping cylinder 10 to the unloading position 42 to supply battery cells to the production line. After unloading, the trays are empty. The tray 5 reaches the lifting belt plate 83 of the second lifting mechanism 9, and after being lowered by the lifting motor 84, it reaches the second conveyor tray 2. The first pull wire device 12 of the second conveyor tray 2 pulls the tray 5 towards the first stacking mechanism 21. After being stacked by the first stacking mechanism 21, the first pull wire device 12 drives the stacked empty tray 5 to the second steering mechanism. In the second steering mechanism, the steering mechanism lifting cylinder 234 lifts the steering mechanism base 231, so that the synchronous belt 232 contacts the bottom of the stacked trays 5, and the stacked empty trays 5 are conveyed... The material is moved to the roller 62 of the second transmission mechanism, and then driven by the second steering mechanism at the other end of the second transmission mechanism 7 to make the stacked material tray 5 reach the first conveying tray 1. The stacked empty material tray 5 is driven by the first pull wire device 12 of the first conveying tray 1 to move towards the first material distribution mechanism 14. After being split by the first material distribution mechanism 14, the individual empty material tray 5 is driven by the first pull wire device 12 or the clamping cylinder 10 to the lifting plate 83 of the first lifting mechanism 8. After being raised by the lifting motor 84, it reaches the loading position 35 of the loading conveying tray 3, completing one cycle at a time.

[0051] It should be noted that the rotation direction of the aforementioned material tray 5 can be changed, and the upper and lower material positions 42 can be changed as needed after the change.

[0052] In this embodiment 1, the material tray 5 has 54 battery cell placement positions, and the material tray 5 is stacked in the stacking space 22 in numbers of 8. Therefore, the storage capacity of the storage mechanism for battery cells is greatly improved. In other embodiments, the number of battery cell placement positions of the material tray 5 and the number of stacks of the material tray 5 in the stacking space 22 can be changed according to requirements. This embodiment does not make specific limitations.

[0053] In summary, the material storage mechanism provided by the present invention has the following technical effects:

[0054] 1. It can stack and disperse the material trays 5 containing battery cells, as well as stack and disperse the empty material trays 5, which meets the supply requirements of the material trays 5 for loading and unloading of high-speed production lines and will not cause the high-speed production line to stop waiting for the material trays 5.

[0055] 2. Since the material storage mechanism can stack a large number of material trays 5, there is no need to stop the operation of other mechanisms when a small problem occurs in the high-speed production line, so that materials can be stored in time and the emergency response capability is strong.

[0056] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
