Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
It should be noted that the terms of spatial relationship, such as "vertical direction" and "horizontal direction", used in the present utility model are matched with the actual direction of the product of the present utility model in the use state, so as to facilitate description. When the actual in-use orientation of the product is changed, the spatial relationship terms should be construed accordingly.
Referring to fig. 1-4, an embodiment of the present utility model provides a stacking device, which includes a frame 1, a material taking mechanism 3 and a driving mechanism 4, wherein the material taking mechanism 3 is disposed on the frame 1, and the driving mechanism 4 is also disposed on the frame 1 and is used for driving the material taking mechanism 3 to lift. Wherein, the feeding mechanism 3 is provided with a plurality of feeding assemblies 31, and the feeding assemblies 31 are arranged along the vertical direction and are all arranged on the frame 1 in a lifting manner. The material taking mechanism 3 is provided with a material taking position (which can be formed by a material feeding part, such as a material feeding conveying line for conveying materials to the material taking mechanism 3), when each material taking assembly 31 is driven by the driving mechanism 4 to move upwards along the vertical direction, the material taking assembly 31 on the uppermost layer firstly moves upwards to a material taking height (the height of the material taking assembly for grabbing the material on the material taking position, such as the height of the material feeding conveying line), reaches the material taking position, and after the material is obtained, the material is carried to move upwards, and then the next material taking assembly 31 moves upwards to the material taking height to obtain the material from the material taking position until the material taking assembly 31 on the lowermost layer is the last material taking assembly 31. In this manner, each take out assembly 31 is moved up to sequentially take out the conveyed materials (e.g., cells) to effect stacking of a plurality of materials.
Meanwhile, any two adjacent material taking assemblies 31 can relatively move, and the layer spacing between the two adjacent material taking assemblies 31 is changed. That is, a spacing adjustment structure is formed between any two adjacent material taking assemblies 31 in the vertical direction, which can adjust the distance and change the layer spacing. In an initial state, or when no material is obtained, the material taking assemblies 31 of each layer may have a small layer spacing, and are compressed together, as shown by the material taking mechanism 3 on the right half side in fig. 1, so that the overall height of all the material taking assemblies 31 is also reduced as the height of the uppermost material taking assembly 31, and the lower material taking height (the height of the feeding conveyor line) can be matched. Then, compared to a mechanism that the spacing cannot adjust the overall synchronous lifting of each material taking assembly 31, the lower or original material taking height can still be matched under the condition of increasing the number of layers of the material taking assemblies 31. In other words, the number of the material taking components 31, i.e., the number of layers, can be increased without changing the original material taking height (maintaining the original height of the feeding conveyor line); and when the material taking assembly 31 moves upwards to stack materials, the material taking assembly 31 has a higher upward moving space, as shown in the upper space of the material taking mechanism 3 on the right half side in fig. 1 and the left half side in fig. 3, which is also beneficial to increasing the layer number of the material taking assembly 31.
In the whole, after the material taking mechanism finishes material taking, a certain interval is reserved between the material taking components 31, so that a manipulator can extend into the layer interval to integrally carry away the multi-layer material, then each material taking component 31 moves downwards in an idle mode, the layer interval is compressed, and the material taking components are folded downwards until the uppermost material taking component 31 is lower than the material taking position, namely, the material taking component enters the material taking position, and one-time material taking and feeding are completed.
By means of the arrangement, the material taking mechanism 3 provided by the utility model can be provided with a plurality of material taking components 31 in the number of layers in the vertical direction, and a single batch can stack a plurality of materials compared with a mechanism with a plurality of material taking components but with fixed spacing between the material taking components due to the variable pitch adjustment performance of the material taking components 31 in the different layers in the vertical direction. Compared with a device with a material taking component 31 with a fixed layer spacing, the stacking device has low space limitation, can match lower material taking height with more material taking components 31, can have more material taking components 31 with more layers on the basis of no need of changing the material taking height, can increase the number of materials stacked in a single batch, and effectively improves stacking efficiency.
In the battery production, when the material taking mechanism 3 is in an initial state, namely an idle state when the battery cells are not stacked, the layer spacing of each material taking assembly 31 is small, the material taking assemblies are integrally folded together, and the overall height is lower than the material taking position. When the electrical cores are stacked by taking the electrical cores, the electrical core is conveyed to the taking position at the taking mechanism 3 by the conveying line, each taking assembly 31 moves upwards to sequentially obtain the electrical cores under the driving of the driving mechanism 4 (after each taking assembly 31 obtains one electrical core, the conveying line can convey the next electrical core to the taking position, and then the next taking assembly 31 moving upwards obtains the electrical core). In the upward movement process, the spacing between the material taking assemblies 31 of each layer is increased so as to take materials in sequence, and the battery cells conveyed by the conveying line are stacked in the vertical direction. As shown in the left-hand side of fig. 1 and the right-hand side of fig. 3 of the take-out mechanism 3, the spacing between the layers of the take-out assembly 31 after taking out the cells is greater than the spacing between the layers before taking out the cells, and the take-out assemblies 31 are in an open and spaced state so that the cells can be moved to the next station (hot press) by other means such as a jig.
Therefore, the stacking device provided by the utility model can not only rapidly stack materials, but also increase the number of single stacking, and effectively improve the stacking efficiency. The stacking device is applied to battery production, so that the stacking and feeding efficiency of the battery cells is improved, and the manufacturing efficiency of the battery cells in the working procedures of hot pressing and the like is also improved.
Meanwhile, in battery production, the stacked battery cores through the stacking device can be moved into the hot pressing device through the carrying device, the stacked battery cores are subjected to multi-layer synchronous hot pressing in the hot pressing device, the stacked battery cores are required to be taken out after the hot pressing is finished, then the battery cores are required to be placed on the conveying lines one by one, and the conveying lines are used for conveying the battery cores to the next working procedure one by one. The stacking device provided by the utility model can also be used for unstacking and feeding stacked battery cells. For example, the stacked battery cells are taken out through the carrying device and the battery cells are spaced, so that the battery cells in each layer are opposite to the material taking assemblies 31 in each layer (the material taking assemblies 31 are in an open state and have larger layer spacing so as to facilitate the placement of the battery cells), and then the battery cells can be placed on the material taking assemblies 31. One cell is secured to each take-off assembly 31. And then each material taking assembly 31 moves downwards with the materials, each layer of material taking assembly 31 sequentially moves downwards to the material taking height to place the materials at the material discharging position (the material discharging position is formed by a material discharging receiving part such as a material discharging conveying line), a plurality of vertically stacked materials are converted into horizontally arranged materials on the material discharging conveying line, and the material discharging and discharging of a plurality of battery cells with different heights are realized.
Because the stacking device provided by the utility model is provided with more material taking assemblies 31, when a plurality of stacked materials such as stacked battery cells after hot pressing are disassembled and discharged, the quantity of the materials disassembled in a single batch is also high, and the materials which are grasped are sequentially placed on the same discharging conveying line to be conveyed by sequentially downwards moving each material taking assembly 31, so that the rapid discharge of the materials with different heights is realized.
As shown in the drawings, in some embodiments, the material taking mechanisms 3 on the frame 1 may be provided with at least two groups, the driving mechanisms 4 are also provided with at least two groups in a matching manner, and the driving mechanisms 4 and the material taking mechanisms 3 are arranged in a one-to-one correspondence manner, so that each group of material taking mechanisms 3 can operate independently, and different material taking mechanisms 3 stack materials in a staggered manner, and the stacked materials are provided in a staggered manner or sequentially, so that the stacking efficiency and the feeding efficiency can be further improved.
In the material taking mechanism 3, any two adjacent material taking assemblies 31 are connected through a telescopic structure in the vertical direction, so that the two adjacent material taking assemblies 31 have relative movement in the vertical direction, and the layer spacing is changed through the relative movement. Meanwhile, the layers of material taking assemblies 31 are connected through a telescopic structure, and the layers of material taking assemblies are still connected with each other to form a whole though having relative movement. When the uppermost material taking assembly 31 moves, each layer of material taking assembly 31 below the uppermost material taking assembly is driven to sequentially move. The driving mechanism 4 is only connected with the uppermost material taking assembly 31 and drives the uppermost material taking assembly 31 to lift, so that the material taking assemblies 31 of all layers can sequentially move upwards to take materials, and sequentially descend to discharge materials or sequentially descend to compress.
In detail, when the driving mechanism 4 drives the uppermost material taking component 31 to move upwards, the uppermost material taking component 31 will first move a certain distance (i.e. the maximum relative movement amount) relative to the underlying second material taking component 31, and then the second material taking component 31 will be pulled to move upwards, and after the second material taking component 31 moves a certain distance relative to the third material taking component 31, the third material taking component 31 will be pulled to move upwards, so that the material taking components 31 can move upwards in sequence and take materials in sequence. At this time, the interval between any two adjacent material taking units 31 is the maximum layer interval, which may be referred to as the first interval, and this state is referred to as the open state. Thus, after each layer of material taking assembly 31 moves up and takes material, in the open state, there is a space between two adjacent layers of material taking assemblies 31 sufficient to hold material and facilitate insertion of other handling components to remove material.
When the material is removed or is required to be discharged, the driving mechanism 4 drives the uppermost material taking component 31 to move downwards, and after the uppermost material taking component 31 moves downwards for a certain distance (the maximum relative movement amount) relative to the second material taking component 31, the uppermost material taking component can be propped against the second material taking component 31, and then can be pressed against or push the second material taking component 31 to move downwards together, and the second material taking component 31 can be pressed against the third material taking component 31, so that all the material taking components 31 are compressed together, and in a compressed state, the adjacent two material taking components 31 have smaller layer spacing which can be recorded as a second spacing. The second interval is smaller than the first interval, the whole material taking mechanism 3 is in a compressed state, as shown in the material taking mechanism 3 on the left half side in fig. 2, the whole height is low, compared with a mechanism that the interval can not adjust the whole synchronous lifting of each material taking component 31, the stacking device provided by the utility model can still be matched with a lower or original material taking height under the condition that the number of layers of the material taking components 31 is increased, so that the stacking device can be said to have more material taking components 31 on the basis that the original material taking height is not required to be changed, and the stacking quantity of single batch materials is increased.
As shown in fig. 2 and 4, in some embodiments, the telescopic structure is a limited sliding structure, and specifically includes a limited connection block 32 and a sliding connection 33. Any two adjacent material taking assemblies 31 in the vertical direction are connected through a limiting sliding structure. The limit connection block 32 is connected with a first one (higher than the other in the vertical direction) of the two material taking components 31, for example, and is provided with a chute extending along the vertical direction; the sliding connection 33 is connected to a second, e.g., lower, of each of the two take-off assemblies 31 and is disposed within and is slidable along the chute. One end of the sliding connecting piece 33 is fixedly connected with the material taking assembly 31, and the other end of the sliding connecting piece is slidably connected in the sliding groove, so that the material taking assembly 31 connected with the sliding connecting piece and the material taking assembly 31 connected with the limiting connecting piece 32 can slide relatively. It can also be said that, except for the uppermost material taking component and the lowermost material taking component, each material taking component 31 between two layers is fixed with a limit connection block 32 and a sliding connection piece 33, and is connected with the upper and lower material taking components 31 adjacent to the limit connection block 32 and the sliding connection piece 33 respectively, for example, is connected with the sliding connection piece 33 on the upper material taking component 31 through the limit connection block 32, and is connected with the limit connection block 32 on the lower material taking component 31 through the sliding connection piece 33. The uppermost material taking assembly 31 is connected with the material taking assembly 31 at the lower layer thereof only through a limit sliding structure and is in transmission connection with the power piece 41 of the driving mechanism 4. The lowest material taking assembly 31 is connected with the material taking assembly 31 on the upper layer through a limiting sliding structure.
In this way, every two adjacent material taking assemblies 31 can relatively move for a certain distance, and when the sliding connecting piece 33 moves to the end part of the sliding groove, the sliding connecting piece abuts against the upper material taking assembly 31 and is driven by the upper material taking assembly 31, so that the whole material taking mechanism 3, namely all the material taking assemblies 31, has an open state and a compressed state.
The limit connection block 32 may be elongated and disposed in a vertical direction. In some embodiments, the chute may be an elongated through hole and the sliding connection 33 may be a cam bearing follower. The cam bearing follower includes a bolt, a roller, and a roller positioned between the bolt head and the roller. When the cam bearing follower moves up and down in the sliding groove, the cam bearing follower rolls relative to the sliding groove, so that friction force is reduced.
Of course, in other embodiments, the limiting sliding structure may also include a sliding rail, a sliding block and a limiting block. One end of the sliding rail is connected with one layer of material taking assembly 31, the limiting block is arranged at the other end of the sliding rail, and the sliding block is positioned between the layer of material taking assembly 31 and the limiting block and is connected with the other layer of material taking assembly 31.
Adjacent two layers of material taking assemblies 31 can be connected through a limited sliding structure to perform pitch adjustment, and in some other embodiments, the telescopic structure can also be a hinge structure or a connecting rod structure. For example, at least two hinges or connecting rods are disposed between every two adjacent material taking assemblies 31, the at least two hinges or connecting rods are hinged in sequence from head to tail, and two ends of the whole are respectively hinged with the two adjacent material taking assemblies 31, so when the driving mechanism 4 drives the uppermost material taking assembly 31 to move up or down, the rest material taking assemblies 31 can also move in sequence, and an open state with a first interval and a compressed state with a second interval can be realized.
The material taking assembly 31 can take materials in a grabbing mode or a lifting mode. The take out assembly 31 may be provided with, but is not limited to, jaws, suction cups, and the like.
In some embodiments, the material taking assembly 31 includes two opposite material taking portions for taking material placed on the material taking level during the upward movement, and for carrying the material upward after the material is taken, where the material, such as a cell, is placed on the two material taking portions. Each layer of material taking assembly 31 comprises two material taking parts which are opposite along the horizontal first direction, and two rows of material taking parts which are opposite at intervals and are arranged from top to bottom are integrally formed. In each column, any two adjacent material taking parts in the vertical direction are connected through the telescopic structure, and the two material taking parts of the uppermost material taking assembly 31 move synchronously, so that the material taking parts of all layers can move synchronously under the driving of the material taking parts in sequence, and the stability is kept.
The take-off level may be formed between two rows of take-off portions, i.e. the feed member conveys material, such as a feed conveyor line, between two rows of take-off portions. When the two material taking parts of each layer move to the material taking height, materials are commonly obtained from the material taking position. The material take-off level may also be formed on one side of two rows of material take-off portions, which in such embodiments may be jaws or suction cups, which grip and hold material from one side of the material.
When the material taking position is located between the two rows of material taking parts, the material taking parts can be clamping jaws, sucking discs or supporting parts for lifting materials. When the material is obtained by upward movement, the supporting parts on the two sides lift the material from bottom to top to take away the material, and after all the layers lift the material, stacking is completed.
Taking stacked battery cells as an example for explanation, the battery cells are sequentially sent to a material taking position by a conveying line, each battery cell protrudes out of a suspension area relative to the conveying line, two rows of supporting parts are positioned on two sides of the conveying line, and when the battery cells move between the two rows of supporting parts and are positioned at the material taking position, the suspension areas on two sides of the battery cells are opposite to the supporting parts on two sides. When the two supporting parts of each layer move up to the height of the conveying line, the two supporting parts are propped against the suspended area of the battery cell from bottom to top to lift the battery cell, and then the battery cell is lifted to move up. After each two supporting parts of one layer of material taking assembly 31 lift the battery cell on the material taking position, the conveying line moves to convey the next battery cell to the material taking position, and then the two supporting parts of the next layer of material taking assembly 31 lift the battery cell. After each layer of supporting part lifts the battery cells, the operation that a plurality of battery cells conveyed horizontally are converted into battery cells which are placed at intervals along the vertical direction and stacked together is realized, the battery cells of each layer are synchronously removed by a carrying part in a stacking state and are sent into a hot pressing device, and the hot pressing part of the hot pressing device presses the stacked battery cells together, so that synchronous hot pressing of a large number of battery cells can be completed at a time.
When the material taking part is a supporting part, the material taking part comprises at least one supporting piece 312, for example, the material taking part comprises a base 311 and the supporting piece 312 fixed on the base 311. The support 312 may be one or two or more. When the support 312 is provided with at least two, at least two of the support 312 are each fixed to the base 311 and arranged in the horizontal second direction. In this way, each supporting piece 312 of each material taking part is fixed on the same base 311 and is synchronously driven to synchronously move, so that stability can be ensured. At the same time, each material is stably lifted and supported by at least four supporting pieces 312, so that the material has good stability and can keep high level. The support members 312 may be plate-like structures with the top end surfaces of the individual support members 312 of each layer of take-off assemblies 31 collectively forming a lifting support surface.
The support 312 may be a block, such as a support block, a plate, such as a support plate, or any other shape, but has a flat lifting surface to smoothly lift the support material.
The driving mechanism 4 needs to drive the two material taking parts of the uppermost material taking assembly 31 to synchronously move, and may include a power part 41 and two lifting parts 42 connected with the power output end of the same power part 41, where the two lifting parts 42 synchronously lift and move on the frame 1 under power driving and are respectively connected with the two material taking parts, so that synchronous driving of the two material taking parts is realized. And the two material taking portions of the uppermost material taking assembly 31 move synchronously, so that the two material taking portions of the same-layer material taking assembly 31 can be driven to move synchronously under the condition that the relative sliding structures among the material taking portions of the layers are the same (the parts and the dimensions are the same), so that the horizontality of the lifting supporting surface formed by a plurality of supporting pieces 312 on each layer is ensured.
The power member 41 may be, but not limited to, a motor, and the elevating member 42 may be a timing belt. As shown in fig. 1 and 4, the frame 1 is frame-shaped, the power member 41 is disposed at the top end of the frame 1, and two lifting members 42 are respectively arranged at two sides of the frame 1. When the lifting member 42 is a synchronous belt, the lifting member can extend from the top end to the bottom end of the frame 1, so that the lifting member is convenient to set, has a long stroke, and is very convenient to drive the material taking assembly 31 to reciprocate up and down.
Further, a guiding structure for guiding the material taking assemblies 31 of each layer is arranged on the frame 1, and the guiding structure guides the material taking assemblies 31 of each layer to reciprocate along the vertical direction, so that the accuracy of the moving direction of the material taking assemblies 31 of each layer is ensured, and the material taking part is prevented from being skewed.
When the material taking assembly 31 comprises two material taking parts arranged at intervals along the horizontal first direction, the guide structure comprises two groups of slide rails 5 arranged along the vertical direction, and the two material taking parts in each material taking assembly 31 are respectively arranged on the two groups of slide rails 5 in a sliding manner. That is, in each material taking mechanism 3, two sets of sliding rails 5 are in one-to-one correspondence with two rows of material taking portions, and each material taking portion in the same row is slidably disposed on the same set of sliding rails 5. Two sets of slide rails 5 are arranged on two sides of the material taking mechanism 3, each set of slide rails 5 corresponds to a row of material taking parts, and in each set of slide rails 5, the number of the slide rails 5 can be one, two or more, and each slide rail 5 extends along the vertical direction. The slide rails 5 in the same group are arranged in the horizontal second direction. The base 311 of the material taking part is fixedly connected with the sliding blocks on the sliding rails 5 in the same group, and stably slides on the sliding rails 5.
