[0037] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0039] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0040] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0042] According to one aspect of the utility model, a cache device is provided, comprising: a turntable 1, a material shifting assembly 100 and a fixed frame 2; the turntable 1 is mounted on the fixed frame 2 and is provided with an inlet 101 and an outlet 102, the turntable 1 can rotate relative to the fixed frame 2 so that the material can be conveyed from the inlet 101 to the outlet 102; the material shifting assembly 100 is located above the turntable 1, and when the outlet 102 is blocked, the material shifting assembly 100 can limit the conveying direction of the material so that it can be arranged along the inside of the turntable 1.

[0043] Specifically, in this embodiment, the material can enter the turntable 1 through the feed port 101, and under the rotation of the turntable 1, it is transported to the discharge port 102, thereby realizing the supply of materials in the current production process. In actual production, after the current process is completed, when the equipment of the next process has no material feeding demand, a large amount of material will be accumulated in the turntable 1, so that the buffer device needs a certain storage capacity.

[0044] The present application sets a material-digging assembly 100 above the turntable 1, so that when the discharge port 102 is blocked, the material can change its original conveying direction, so that the material enters the turntable 1 from the feed port 101 and is gradually arranged in the turntable 1 through the blocking or restriction of the material-digging assembly 100. This not only improves the ability of the buffer device to temporarily store materials, but also avoids the situation where a large amount of materials are piled up in the same area and cause the materials to be stuck or poured, so that when the next process needs to be fed, the materials can be discharged from the discharge port 102 in sequence, thereby improving production efficiency. Among them, the material-digging assembly 100 can be set above the turntable 1 either directly above or obliquely above, as long as it can achieve its function, and the present invention does not limit this.

[0045] In the above embodiment, the blockage of the discharge port 102 may be caused by the material blockage caused by stopping the discharge of the discharge port 102 because the next process does not need to feed the material, or by interference from equipment or external factors. When the blockage is caused by external factors, the setting of the material shifting assembly 100 enables the material entering the turntable 1 to be transported to other positions in time, avoiding the situation of material jamming or material spillage at the discharge port 102. Among them, the cache device can be applied to battery production for feeding and storing materials in the support cup, which not only reduces the occupied space of the production device, but also improves the efficiency of battery production.

[0046] In the above embodiment, the rotation direction of the turntable 1 is usually from the feed port 101 to the discharge port 102, and the rotation of the turntable 1 can be achieved by the first motor 15. In addition, the positions of the feed port 101 and the discharge port 102 can usually be set close to avoid affecting the discharge efficiency when the buffer device provides feeding, and the material shifting component 100 can also be set at a position close to the feed port 101, so that the material entering the turntable 1 can be arranged to a position far away from the discharge port 102 in time when the material is buffered. The specific design can be made according to actual needs.

[0047] Optionally, there are multiple turntables 1, which are stacked in sequence with intervals between them. The number of the material-selecting components 100 is the same as that of the turntables 1, and they are arranged one-to-one with the turntables 1 respectively; the cache device also includes multiple transition logistics lines 3, and the transition logistics lines 3 connect the inlet 101 and the outlet 102 of two adjacent turntables 1, so that the material can be transported from the outlet 102 of one turntable 1 to the inlet 101 of the adjacent turntable 1.

[0048] In this embodiment, by providing a plurality of turntables 1 and a matching number of material-diverting components 100, the plurality of turntables 1 stacked at intervals can sequentially convey or buffer materials through the transitional logistics line 3. The material flow between two adjacent turntables 1 is realized through the transitional logistics line 3, so that the material can be conveyed layer by layer from the turntable 1 at the top layer to the turntable 1 at the bottom layer, or from the turntable 1 at the bottom layer to the turntable 1 at the top layer, and the specific conveying direction can be selected according to actual needs.

[0049] Among them, multiple turntables 1 can be assembled on the second rotating shaft 16, and the second rotating shaft 16 is connected to the output end of the first motor 15, so that the first motor 15 can drive multiple turntables 1 to rotate simultaneously. Multiple transitional logistics lines 3 can be respectively provided with second motors 17 for driving, so as to facilitate the individual control of each transitional logistics line 3. In addition, the rotation direction of the turntable 1 when the material is transported from top to bottom is opposite to the rotation direction of the turntable 1 when the material is transported from bottom to top.

[0050] In the above embodiment, the buffer device has two working states, one is a normal feeding state, and the other is a storage state. When the buffer device is in the feeding state, for example, the buffer device needs to discharge the material from the lowest level turntable 1 to the material-using equipment. At this time, the material can be fed through the feed port 101 of the top level turntable 1, and the material is sequentially transported to the discharge port 102 through the feed port 101 of the top level turntable 1, and the discharge port 102 is connected to the feed port 101 of the adjacent lower level turntable 1 through a transitional logistics line 3, so that the material can be transported from the discharge port 102 of the top level turntable 1 through the transitional logistics line 3 to the feed port 101 of the adjacent lower level turntable 1, and then through the rotation of the turntable 1, it is transported to its discharge port 102, and so on, until the material is transported to the bottom level turntable 1, and then transported to the material-using equipment from the discharge port 102 of the bottom level turntable 1, completing the entire feeding process.

[0051] When the material-consuming equipment no longer needs to consume materials, the material discharging port 102 of the turntable 1 at the bottom layer of the buffer device no longer discharges materials, and the buffer device begins to be in a material storage state. At this time, materials continue to enter the inlet 101 of the bottom turntable 1, while the outlet 102 is blocked by materials because it no longer discharges materials, causing the inlet 101 and the outlet 102 of the turntable to begin to accumulate materials. Through the action of the material shifting component 100, the materials are arranged in sequence from the outer circle to the inner circle of the bottom turntable 1. When the bottom turntable 1 is full of materials, its inlet 101 can no longer enter the materials, so that the materials at the outlet 102 of the upper turntable 1 adjacent to the bottom turntable 1 can no longer enter the inlet 101 of the bottom turntable through the transition logistics line 3 (the transition logistics line 3 of the current layer can be stopped at this time), resulting in the outlet 102 of the upper turntable 1 adjacent to the bottom turntable 1 being blocked by materials. Through the action of the material shifting component of the current layer, the materials entering this layer also begin to be arranged in sequence from the outer circle to the inner circle, and so on. After the materials fill the turntable 1 on the top layer, the feeding of the entire buffer device can be stopped to achieve large-scale stacking of materials.

[0052] By setting up multiple turntables 1, the storage capacity of the entire cache device for materials is greatly increased, and it does not occupy too much factory space, which is conducive to the transportation and use of materials at any time. In practical applications, a special detection device can be set to detect the stacking state of materials in each turntable 1, and then the feeding of each layer can be controlled by a control device, and the utility model does not limit this.

[0053] Optionally, the material shifting assembly 100 includes a fixed rod 20, a shifting rod 10 and a first rotating shaft 9; the fixed rod 20 is fixed on the fixed frame 2, the shifting rod 10 is fixed on the first rotating shaft 9, the first rotating shaft 9 is rotatably arranged on the fixed rod 20, and the shifting rod 10 has an initial position and a full material position; when the discharge port 102 is in an unobstructed state, the shifting rod 10 is located at the initial position, and the turntable 1 can transport the material from the feed port 101 to the discharge port 102; when the discharge port 102 is in a blocked state, the shifting rod 10 can control the conveying direction of the material, and when the turntable 1 is full of material, the shifting rod 10 is located at the full material position.

[0054] Specifically, in this embodiment, the lever 10 is movably arranged above the turntable 1 through the fixed rod 20. When the corresponding discharge port 102 of the turntable 1 is in a blocked state, the material further accumulates so that it can push the lever 10 to move from the initial position to the full position, thereby enabling the material to move from the outer ring to the inner ring of the turntable 1 and continue to be arranged in sequence. As the material continues to enter, the lever 10 is gradually pushed to the full position. Among them, the initial position of the lever 10 is usually set to allow a material size to pass between the free end of the lever 10 and the edge of the turntable 1. This distance can be designed to be slightly larger than the size of a material, so that when the buffer device normally transports the material to the material-using equipment, the lever 10 will not affect the movement of the material from the feed port 101 to the discharge port 102, and when the material needs to be stored (i.e., when the discharge port 102 is blocked), a small amount of material accumulation can push the lever 10 to move in the direction of the full position, so as to achieve the purpose of arranging the material from the outer ring to the inner ring of the turntable 1 in sequence.

[0055] Optionally, the material shifting assembly 100 further includes a limiter, and the limiter is used to limit the rotation range of the shifting rod 10 so that the shifting rod 10 can be in the initial position or the full material position.

[0056] Specifically, in this embodiment, since the feed port 101 and the discharge port 102 are usually close to each other, preferably not exceeding 180°, the setting of the limiter allows the lever 10 to rotate within a set angle range, so that the lever 10 can rotate within the area between the feed port 101 and the discharge port 102, so as to improve the material selection efficiency of the lever 10, and avoid the lever 10 being in an invalid area due to the pushing of the material, which affects the arrangement of the material in the turntable 1. Among them, the rotation angle of the lever 10 can usually be set to between 30° and 60°, for example, about 50°, and can be determined according to the area occupied by the material when the material tray is full of material, and the present utility model does not limit this. Among them, the full material position refers to the position of the lever 10 when the material is arranged in the turntable 1 and occupies a certain area ratio. It needs to be set according to actual needs and the operating status of the equipment, and is not necessarily the position when the material fills the turntable 1.

[0057] Optionally, the limiting member includes a stop block 6 and a first stop screw 4 and a second stop screw 5; the first stop screw 4 and the second stop screw 5 are fixed to the fixing rod 20 and are respectively located on both sides of the stop block 6, and the first end of the stop block 6 is fixed to the first rotating shaft 9; when the lever 10 is located at the initial position, the first stop screw 4 can block the movement of the second end of the stop block 6, and limit the rotation of the lever 10 in the direction away from the full position; when the lever 10 is located at the full position, the second stop screw 5 can block the movement of the second end of the stop block 6, and limit the rotation of the lever 10 in the direction away from the initial position.

[0058] Specifically, in this embodiment, the first stop screw 4 and the second stop screw 5 are respectively arranged on both sides of the stop block 6, so that when the first end of the stop block 6 rotates around the first rotating shaft 9, the second end can be respectively limited within a set rotation range by the first stop screw 4 and the second stop screw 5. Further, since the lever 10 is fixed on the first rotating shaft 9, by limiting the rotation range of the stop block 6, the lever 10 can also be correspondingly limited within a set rotation angle through the transmission of the first rotating shaft 9, thereby realizing the limiting effect on the lever 10.

[0059] In the above embodiment, by limiting the rotation of the lever 10 between the initial position and the full material position, the lever 10 is prevented from rotating outside the material shifting area, thereby improving the accuracy of the position and quantity of the material arrangement in the turntable 1 when the discharge port 102 is blocked, and the structure of the limiter is relatively simple, which is convenient for disassembly and maintenance.

[0060] Optionally, the material shifting assembly 100 further includes an elastic member 7, one end of which is fixed to the fixing rod 20, and the other end of which is fixed to the second end of the stop block 6, so that the shifting rod 10 can move from the full material position to the initial position.

[0061] Specifically, in actual application, after the lever 10 is gradually pushed to the full position by the material, it needs to be restored to the initial position when it is used next time. In this embodiment, by providing the elastic member 7, after the material in the turntable 1 is gradually transported out of the turntable 1 from the discharge port 102, the restoring force of the spring can pull the second end of the stop block 6, so that the lever 10 can be restored to the initial position as the first rotating shaft 9 rotates through the stop block 6, thereby realizing the automatic return of the lever 10. Among them, the elastic member 7 can be realized by a spring or the like.

[0062] Optionally, the material shifting assembly 100 also includes a damper 8, and the stop block 6 is assembled on the first rotating shaft 9 through the damper 8; the damper 8 is used to prevent the shifting rod 10 from moving from the full material position to the initial position, and the damping force of the damper 8 is smaller than the restoring force of the elastic member 7.

[0063] Specifically, in actual applications, the restoring force of the elastic member 7, without restriction, will drive the lever 10 to quickly return from the full material position to the initial position. In this process, the material in the turntable 1 is easily hit by the lever 10, causing material to fall or fly, and the operator is easily injured. In this embodiment, the damper 8 is installed between the stop block 6 and the first rotating shaft 9, and the damping force is smaller than the restoring force of the elastic member 7, so that the lever 10 can slowly return to the initial position under the joint action of the elastic member 7 and the damper 8, avoiding the occurrence of the lever 10 knocking down the material, thereby improving the safety of the equipment. Among them, the damper 8 is a one-way damper 8, which only provides damping force during the process of spring contraction and reset.

[0064] In actual application, when the turntable 1 is in a full material state or partially stacked with materials, if the subsequent process needs to feed materials, the materials begin to flow out from the discharge port 102, and the lever 10 is equipped with a damper 8 and an elastic member 7, so that when the elastic member 7 contracts and resets, the lever 10 is pushed outward, and the damper 8 starts to work, so that the speed of the lever 10 pushing outward is slowed down until the material is pushed to the outermost circle of the turntable 1 and flows out, thereby achieving the purpose of smooth discharge.

[0065] Optionally, the material shifting assembly 100 further includes a proximity sensor 11, which is configured to determine the material distribution state of the material in the turntable 1 by detecting the position of the shifting rod 10; when the proximity sensor 11 detects that the shifting rod 10 is at the full material position, the corresponding transition logistics line 3 connected to the feed port 101 of the turntable 1 stops running to stop feeding.

[0066] Specifically, the proximity sensor 11 is a general term for a sensor that can detect the movement and presence of a detection object without contacting it. It can use the displacement sensor to have sensitive characteristics to approaching objects to identify the approach of an object and output a corresponding switch signal. There are many types of proximity sensors 11, which can detect the approach of an object by using electromagnetic induction, electrostatic capacitance change, ultrasound, photoelectric or magnetic force, and the proximity sensor 11 has the characteristics of long service life, reliable operation, high repeated positioning accuracy, no mechanical wear, no sparks, no noise, and strong vibration resistance.

[0067] In this embodiment, the position of the lever 10 can be detected in real time by using a proximity sensor 11, and the position of the lever 10 can be used to determine whether the material stacking amount in the turntable 1 has reached the set stacking amount, thereby achieving the purpose of controlling the material placement amount in the turntable 1. In practical applications, when there are multiple turntables 1, a proximity sensor 11 can be set on each layer of turntable 1 so that when the material on the current turntable 1 is stacked to a full state, the material can be stopped from entering the current turntable 1 by controlling the device, thereby achieving a full state on each layer of turntable 1 in turn. The provision of the proximity sensor 11 improves the automation level of the entire cache device and improves the stacking efficiency of materials. Among them, stopping the feeding of the current turntable 1 can be achieved by stopping the operation of the corresponding transition logistics line 3.

[0068] Furthermore, by providing the proximity sensor 11, the phenomenon of material spillage or material jamming caused by excessive material stacking in the current turntable 1 can be avoided, thereby improving the safety of the equipment.

[0069] Optionally, it further includes a feed logistics line 12 and a discharge logistics line 13 , wherein the feed logistics line 12 is connected to the feed inlet 101 , and the discharge logistics line 13 is connected to the discharge outlet 102 .

[0070] Specifically, in practical applications, by setting a feed flow line 12 at the feed port 101, external materials can be transported to the turntable 1 through the feed port 101, and the operation of the feed flow line 12 can be realized by the third motor 18. The discharge flow line 13 set at the discharge port 102 can output the materials in the turntable 1 to the equipment that needs to use the materials in sequence, thereby realizing the continuity between the buffer device and the material device. All kinds of logistics lines can be realized by belts or other conveying equipment, and the present invention does not limit this.

[0071] In some embodiments, when multiple turntables 1 are stacked at intervals, the feed logistics line 12 and the discharge logistics line 13 are respectively connected to the feed port 101 or the discharge port 102 of the top layer and the feed port 101 or the discharge port 102 of the bottom layer to realize sequential transportation of materials from top to bottom or from bottom to top.

[0072] Optionally, a gap-eliminating block 14 is movably provided at the feed port 101 and the discharge port 102 , and the feed flow line 12 and the discharge flow line 13 are connected to the feed port 101 and the discharge port 102 respectively through the gap-eliminating block 14 .

[0073] Specifically, in this embodiment, the gap-eliminating blocks 14 are arranged at the feed port 101 and the discharge port 102 of the turntable 1, so that the connection between the feed port 101 and the feed logistics line 12, and the discharge port 102 and the discharge logistics line 13 is more stable, the gap between the logistics line and the turntable 1 is eliminated, and the probability of material jamming and material dumping caused by the fluctuation when the turntable 1 rotates is reduced, thereby improving the safety and stability of the equipment. Among them, when a plurality of turntables 1 are stacked at intervals, the gap-eliminating blocks 14 arranged at the feed port 101 and the discharge port 102 of the turntable 1 of the middle layer can eliminate the gap between the transition logistics line 3 and the turntable 1.

[0074] Furthermore, a plurality of top screws may be provided at the bottom of the turntable 1, and the flatness and parallelism of the turntable 1 may be adjusted by adjusting the top screws, so that the rotation of the turntable 1 is more stable and safe. In practical applications, the number of top screws may be three or six, etc., and the design is specifically based on actual needs.

[0075] Furthermore, in practical applications, a pressure plate 19 can be set in the area between the feed port 101 and the discharge port 102 on the turntable 1 to prevent the material from falling over or getting stuck during the process of being transported from the feed port 101 to the discharge port 102 and during the process of being arranged and stacked along the turntable 1.

[0076] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
