For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Refer to the following Figures 1 to 6 The utility model introduces a batch feeding device.

[0033] Specifically, Figure 1 , Figure 2 As shown, in this embodiment, the batch feeding device mainly includes a detection and positioning mechanism 1, a conveying mechanism 2 and a storage mechanism 3. The detection and positioning mechanism 1 is used to detect and classify the battery cells, the conveying mechanism 2 is used to convey the battery cells, and the storage mechanism 3 can arrange and store good battery cells in a manner that meets the requirements of the carrier installation, that is, the storage mechanism 3 has a storage spacing, and the storage spacing is equal to the installation spacing of the carrier, so as to facilitate the subsequent installation process, multiple arranged good battery cells are loaded into the carrier at one time.

[0034] More specifically, if Figure 1 , Figure 2 As shown, in this embodiment, the detection and positioning mechanism 1 includes a frame, on which are arranged a defective storage component 15, a detection carrying component 12 and a detection and positioning component 14. The detection carrying component 12 can carry n battery cells (n>1) at the same time, and the detection and positioning component 14 can detect the battery cells located at the detection carrying component 12 to distinguish good battery cells from defective battery cells. Among them, the defective storage component 15 is used to store defective battery cells.

[0035] Continue to refer to Figure 2 As shown, the transport mechanism 2 is located between the detection and carrying assembly 12 and the storage mechanism 3, and the transport mechanism 2 has at least two working states. In the first working state, the transport mechanism 2 transports the battery cell at the detection and positioning mechanism 1. When the battery cell is determined to be a defective battery cell by the detection and positioning assembly 14, the transport mechanism 2 can transport the battery cell located at the detection and carrying assembly 12 to the defective storage assembly 15; in the second working state, the transport mechanism 2 transports the battery cell between the detection and positioning mechanism 1 and the storage mechanism 3. When the battery cell is determined to be a good battery cell by the detection and positioning assembly 14, the transport mechanism 2 can transport the battery cell located at the detection and carrying assembly 12 to the storage mechanism 3. In other words, the transport mechanism includes at least two transport routes, the first transport route includes the detection and carrying assembly 12 and the defective storage assembly 15, and the second transport route includes the detection and positioning mechanism 1 and the storage mechanism 3.

[0036] In actual application, the detection and positioning mechanism 1 also includes a temporary storage carrying component 13, which is used to store good battery cells. When the battery cell is determined to be a good battery cell by the detection and positioning component 14, the transport mechanism 2 transports the battery cell located in the detection carrying component 12 to the storage mechanism 3, or transports it to the temporary storage carrying component 13 for temporary storage. In other words, the transport mechanism 2 also has a third transport route, which includes the detection carrying component 12 and the temporary storage carrying component 13.

[0037] Specifically, the detection carrying component 12 includes n detection carrying seats 121, the conveying mechanism 2 has m suction cup components 221, the temporary storage carrying component 13 includes a temporary storage carrying seat 131, and the defective storage component includes a storage box 151, wherein n=m; when the conveying mechanism 2 is in the first working state, that is, the conveying mechanism 2 conveys the battery cells at the detection positioning mechanism 1, it mainly includes the following two situations: m suction cup components 221 contact n battery cells located in the detection carrying seat 121 and convey them to the storage box 151, or j suction cup components 221 contact j battery cells located in the detection carrying seat 121 and convey them to the storage box 151, i suction cup components 221 contact i battery cells located in the detection carrying seat 121 and convey them to the temporary storage carrying seat 131, wherein j<n, i=nj, that is, when n battery cells on the detection carrying seat 121 are all determined to be defective battery cells by the detection positioning component 14 When the transport mechanism 2 is in the second working state, that is, the transport mechanism 2 transports the n battery cells located on the detection support seat 121 to the storage box 151 through the m suction cup assemblies 221. When only some of the n battery cells on the detection support seat 121 are determined to be defective battery cells by the detection positioning assembly 14, the defective battery cells will be transported to the storage box 151 by the transport mechanism 2, and the good battery cells will be transported to the temporary storage support seat 131 by the transport mechanism 2; when the transport mechanism 2 is in the second working state, that is, the transport mechanism 2 transports the battery cells between the detection positioning mechanism 1 and the storage mechanism 3, mainly including the following two situations: m suction cup assemblies 221 contact with n battery cells located in the detection support seat 121 and transport them to the storage mechanism 3, or p suction cup assemblies 221 contact with the battery cells located in the detection support seat 121, q suction cup assemblies 221 contact with the battery cells located in the temporary storage support seat 131 and transport them to the storage mechanism 3, wherein p+q=m;That is to say, when the n battery cells on the detection support seat 121 are all determined to be good battery cells by the detection positioning component 14, the conveying mechanism 2 will convey all the battery cells on the detection support seat 121 to the storage mechanism 3 through the m suction cup components 221. When some of the battery cells on the detection support seat 121 are determined to be good battery cells by the detection positioning component 14, the defective battery cells will be conveyed to the storage box 151 by the conveying mechanism 2, and the good battery cells will be conveyed to the temporary storage support seat 131 by the conveying mechanism 2, and wait for the next batch of n battery cells to arrive at the detection support component 12 for detection. If all the n battery cells in the next batch are good battery cells, they will be conveyed by the conveying mechanism 2. When transported to the storage mechanism 3, if some of them are good battery cells, the bad battery cells in the batch will be transported to the storage box 151 by the transport mechanism 2. When the number of good battery cells is equal to the number of battery cells in the temporary storage support seat 131 plus the number of battery cells in the temporary storage support seat 131, the suction cup assembly 221 can transport the above-mentioned good battery cells to the storage mechanism 3. Since the battery cells stored in the temporary storage support seat 131 are good battery cells, it can be ensured that when the transport mechanism 2 is in the second state, that is, when moving between the detection and positioning mechanism 1 and the storage mechanism 3, the number of cells transported each time is the maximum number that the suction cup assembly 221 can absorb, thereby improving the transport efficiency. In addition, in order to avoid excessive accumulation of battery cells in the temporary storage support seat 131, it should be ensured that all good battery cells in the detection support assembly 12 can be transported, and the remaining suction cup assemblies 221 transport the battery cells in the temporary storage support seat 131. ;

[0038] Exemplarily, when n=2, if only one of the first batch of battery cells is a good battery cell, the transport mechanism 2 transports the good battery cell from the detection carrier assembly 12 to the temporary storage carrier assembly 13, and moves the bad battery cell from the detection carrier assembly 12 to the storage box 151. After the next batch of battery cells is inspected, if only one of them is a good battery cell, the number of good battery cells on the detection carrier assembly 12 and the temporary storage carrier assembly 13 reaches 2. At this time, the transport mechanism 2 transports the two good battery cells together to the storage mechanism 3, and moves the bad battery cell from the detection carrier assembly 12 to the storage box 151. If two of them are good, the number of good battery cells on the detection carrier component 12 and the temporary storage carrier component 13 is 3, that is, not less than 2. At this time, the two good battery cells are transported together to the storage mechanism 3, and the remaining one good battery cell is placed on the temporary storage carrier component 13, waiting for the detection result of only one good battery cell in a batch to appear again, and then the two good battery cells are transported together to the storage mechanism 3.

[0039] For example, when n=3, if only one of the first batch of battery cells is a good battery cell, the transport mechanism 2 transports one good battery cell from the detection carrier assembly 12 to the temporary storage carrier assembly 13, and moves two bad battery cells from the detection carrier assembly 12 to the storage box 151. After the next batch of battery cells are inspected, if only one of them is a good battery cell, there are two good battery cells on the detection carrier assembly 12 and the temporary storage carrier assembly 13, which is less than three. At this time, the two good battery cells are transported to the temporary storage carrier assembly 13 together by the transport mechanism 2, and the two bad battery cells are moved away from the detection carrier assembly 12, and wait for the next batch. If two of them are good, there are three good battery cells on the detection carrier assembly 12 and the temporary storage carrier assembly 13. At this time, the three good battery cells are transported to the storage mechanism 3 together, and one bad battery cell is moved from the detection carrier assembly 12 to the storage box 151. If three of them are good battery cells, then there are four good battery cells on the detection carrier component 12 and the temporary storage carrier component 13. In this case, all three good battery cells on the detection carrier component 12 are moved to the storage mechanism, or three good battery cells from the four good battery cells are moved together to the storage mechanism 3, and the remaining one good battery cell is placed on the temporary storage carrier component 13, waiting for the detection result of only two good battery cells in a batch to appear again, and then the three good battery cells are moved together to the storage mechanism 3.

[0040] By setting up a temporary storage carrying component 13 to carry the good battery cells obtained after inspection, and setting up a transport mechanism 2 capable of simultaneously transporting m battery cells, it is possible to transport n good battery cells to the storage mechanism 3 at one time after the battery cells are inspected and classified, so that multiple good battery cells that meet the carrier installation requirements can be quickly stored in batches in the storage mechanism 3, and then multiple good battery cells can be conveniently and quickly installed in batches on the carrier, thereby realizing batch feeding and improving the production efficiency of production processes such as electroplating of battery cells.

[0041] Optionally, in some embodiments, the battery cells to be tested can be directly transported to the test bearing assembly 12 by the transport mechanism 2. For example, taking a common horizontal multi-joint robot as an example, within its working radius, a feeding area, a testing area, a discarding area and a storage area are respectively arranged along the circumferential direction, the feeding area stacks the battery cells to be tested, the testing area is provided with the above-mentioned testing and positioning mechanism 1, the discarding area is used to stack the bad battery cells obtained by the test, and the storage area is provided with the above-mentioned storage mechanism 3. In practical applications, in the production process, after completing one of the processes, the battery cells can be temporarily stored in the transit storage equipment, or directly transported to the next process. The transit storage equipment and the previous process are the aforementioned feeding area, that is, the transport mechanism 2 has a third working state and a fourth transport path. In the third working state, the transport mechanism 2 transports the battery cells between the end of the previous process and the testing and positioning mechanism 1, and the fourth transport path includes the end of the previous process and the testing and positioning mechanism 1, or, in the third working state, the transport mechanism 2 transports the battery cells between the transit storage equipment and the testing and positioning mechanism 1, and the fourth transport path includes the transit storage equipment and the testing and positioning mechanism 1.

[0042] In order to improve work efficiency, in some embodiments, the batch feeding device also includes a transmission component 11, and the transmission component 11 is located at the end of the detection and positioning mechanism 1 away from the storage mechanism 3. The transmission component 11 has a transmission path, and the detection and positioning mechanism 1 is located at the transmission end of the transmission path. Specifically, the transmission component 11 includes a motor and a plurality of conveyor belts, and the conveyor belts are arranged along the transmission path, so that the battery cells can be transported along the preset transmission path to transport the battery cells to the detection and positioning mechanism 1. In this way, the feeding area can be set away from the horizontal multi-joint robot, thereby increasing the man-machine distance during loading, which is conducive to improving safety. In addition, by limiting the moving range of the conveying mechanism 2 so that it only moves between the detection and positioning mechanism 1 and the storage mechanism 3, the efficiency of transporting good battery cells to the storage mechanism 3 can be improved.

[0043] Exemplarily, in some embodiments, a plurality of transmission components 11 may be provided, and the plurality of transmission components 11 are respectively provided between the detection carrying component 12 and the temporary storage carrying component 13, between the detection carrying component 12 and the defective storage component 15, and between the defective storage component 15 and the waste area, so that good battery cells are transmitted from the detection carrying component 12 to the temporary storage carrying component 13, defective battery cells are transmitted from the detection carrying component 12 to the defective storage component 15, and defective battery cells are transmitted from the defective storage component 15 to the waste area. In this way, the conveying mechanism 2 only needs to perform the conveying work from the detection positioning mechanism 1 to the storage mechanism 3, which is also within the scope of protection of the present utility model.

[0044] For example, Figure 3As shown, multiple detection bearing seats 121, between the detection bearing seat 121 and the temporary storage bearing seat 131, and between multiple suction cup assemblies 221 are all arranged in parallel with equal spacing to ensure that the suction cup assembly 221 can accurately absorb multiple battery cells. In order to enable the suction cup assembly 221 to absorb battery cells from the temporary storage bearing seat 131 and the detection bearing seat 121 at the same time, preferably, the temporary storage bearing seat 131 is arranged on one side of the detection bearing seat 121, that is, to ensure that each detection bearing seat 121 has a temporary storage bearing seat 131 on its adjacent side. For example, when the number of detection carriers 121 is two, a temporary storage carrier 131 is provided on the side away from each other of the two detection carriers 121. If there is only one good battery cell, it can be moved to the temporary storage carrier 131 adjacent to the detection carrier 121 where it is located. When the number of detection carriers 121 is three, the detection carriers 121 and the temporary storage carriers 131 are alternately arranged so that there are only one or two good battery cells, the suction cup assembly 221 can still absorb three continuously distributed good battery cells for transportation, thereby improving the transportation efficiency.

[0045] For example, Figure 2 , Figure 3 As shown, one end of the detection support seat 121 is adjacent to the transmission end of the transmission path, and the storage box 151 is located at the other end of the detection support seat 131, and the bottom surface of the storage box 151 is inclined. Under this structure, after the good battery cells are transported to the temporary storage support seat 131, the conveyor belt of the transmission component 11 can drive the next batch of battery cells to move, and push the defective battery cells still located in the detection support seat 121 until they fall into the storage box 151. The defective battery cells can be stacked and accommodated in the storage box 151 at an angle by gravity. Specifically, the transmission component 11, the detection carrier component 12 and the defective storage component 15 are arranged in sequence along the first direction (i.e., the transmission direction), and the defective storage component 15 is located between the detection carrier component 12 and the conveying mechanism 2, and the temporary storage carrier component 13 is arranged along the second direction with the detection carrier component 12 (the second direction is perpendicular to the first direction), so that the detection carrier component 12 and the defective storage component 15 are both located on the moving path of the conveying mechanism 2 from the detection carrier component 12 to the storage mechanism 3, so as to achieve the optimal efficiency of conveying good battery cells and defective battery cells.

[0046] Furthermore, if Figure 5 , Figure 6As shown, the transport mechanism 2 includes a transport robot 21 and a transport jig 22, the transport jig 22 is installed at the execution end of the transport robot 21, and the transport robot 21 is signal-connected to the above-mentioned detection and positioning component 14. The transport jig 22 includes n adsorption plates 222 and suction cup assemblies 221, and each adsorption plate 222 is installed with a suction cup assembly 221 to carry n battery cells at the same time. Each suction cup assembly 221 is individually connected to a pneumatic switch and can be individually controlled so that the transport jig 22 can absorb and release a single battery cell. Of course, in some embodiments, n suction cup assemblies 221 can also be installed on one adsorption plate 222. Therefore, the number of adsorption plates 222 is not specifically limited in the utility model, as long as the normal movement of the mechanism can be achieved.

[0047] Exemplarily, the handling jig 22 can simultaneously absorb one good battery cell and one bad battery cell at the detection carrier component 12, and release the good battery cell alone when it moves to the temporary storage carrier component 13, and release the bad battery cell when it moves to the bad storage component 15.

[0048] Furthermore, two conveying mechanisms 2 are provided in the batch feeding device, and each conveying mechanism 2 is provided corresponding to a detection and positioning mechanism 1, so as to further improve the conveying efficiency after detection.

[0049] like Figure 4 , Figure 5 As shown, in this embodiment, the detection and positioning component 14 includes a visual sensor 141, which can distinguish good and bad battery cells conveniently and quickly by image recognition, and locate the battery cells on the detection and carrying component 12, so that the transport mechanism 2 can adsorb the battery cells. Of course, in some other embodiments, other types of sensors can also be used as long as they can achieve the distinguishing function.

[0050] Furthermore, the handling jig 22 also includes a rotating part, and each suction cup assembly 221 is separately connected to a rotating part, and the position of the suction cup assembly 221 is adjusted by the rotating part. In this way, after the visual sensor 141 locates the battery cell on the detection carrier assembly 12, the suction cup assembly 221 can adsorb and correct the battery cell to put the battery cell in a preset state, so that the battery cell stored in the storage mechanism 3 is placed according to the preset state, which is beneficial to improve the efficiency and accuracy of installing the battery cell on the carrier.

[0051] More specifically, in this embodiment, the batch feeding device includes two detection and positioning mechanisms 1, each of which includes a detection bearing assembly 12, a detection and positioning assembly 14, a transmission assembly 11, a temporary storage bearing assembly 13, and a defective storage assembly 15. Each detection bearing assembly 12 includes two detection bearing seats 121, each detection bearing seat 121 is used to carry a battery cell transmitted by the corresponding transmission assembly 11. The detection bearing seat 121 includes a conveyor belt to facilitate docking with the transmission assembly 11 in this embodiment. Preferably, both the transmission assembly 11 and the detection bearing seat 121 use a stepper motor to accurately control the conveying distance and speed, so that the battery cell can have a certain residence time for detection by the detection and positioning assembly 14 after being conveyed to the detection bearing seat 121. Each detection and positioning assembly 14 includes two visual sensors 141, each visual sensor 141 is used to detect a battery cell on a detection bearing seat 121. Each temporary storage bearing assembly 13 includes two temporary storage bearing seats 131, each temporary storage bearing seat 131 is used to carry a good battery cell. Each defective storage component 15 includes two storage boxes 151, and each storage box 151 is used to store defective battery cells adsorbed from a detection support seat 121. The batch feeding device can detect 4 battery cells synchronously, thereby improving the detection efficiency and feeding efficiency. In order to improve the placement stability of the battery cells, the temporary storage support seat 131 includes a seat body and a first adsorption component, and the first adsorption component at least includes a vacuum pump, an air control valve and a cover body. A plurality of channels are opened on the seat body, and the cover body is arranged at the bottom of the seat body and covers one end of the plurality of channels. The vacuum pump is connected to the cover body through an air supply pipe, and the air control valve is arranged on the air supply pipe. In the working state, the battery cell is located on the seat body, and the two ends of the channel are respectively connected to the battery cell and the cover body. The vacuum pump body is turned on or off so that the seat body can adsorb or release the battery cell. It should be noted that the structure of the first adsorption component is not limited here in the case where the battery cell can be adsorbed to make it stably placed.

[0052] Continue to refer Figure 1 , Figure 2 As shown, the storage mechanism 3 includes a loading bearing assembly 31, and the loading bearing assembly 31 includes at least two loading bearing plates 311, each of which is used to carry a battery cell. Preferably, the storage mechanism 3 includes a second adsorption assembly, and each loading bearing plate 311 is connected to the second adsorption assembly to adsorb and fix the good battery cell to prevent the position from moving. The structure of the second adsorption assembly is the same as that of the first adsorption assembly.

[0053] Further, the loading support plates 311 are arranged along a preset storage spacing, and the storage spacing is the same as the battery cell installation spacing on the carrier to meet the installation requirements of the carrier. Exemplarily, in this embodiment, the storage mechanism 3 includes two loading support components 31 arranged along the second direction, each loading support component 31 includes a plurality of loading support plates 311 arranged in two columns and multiple rows, and the number of loading support plates 311 in each loading support component 31 is the same as the number of battery cells that the carrier can accommodate. The column spacing (i.e., the spacing between the two columns) and the row spacing (i.e., the spacing between the two rows) between the loading support plates 311 are the same as the column spacing and row spacing of the battery cells on the carrier, so that the multiple battery cells carried by each loading support component 31 can be directly installed in batches into the carrier, avoiding the step of adjusting the column spacing and row spacing between the battery cells again.

[0054] Specifically, Figure 1 , Figure 2 As shown, the batch feeding device also includes a loading robot 32, which installs the good battery cells located in a loading bearing assembly 31 into the carrier in batches according to the preset storage spacing. It should be noted that the storage spacing is set according to the installation spacing of the carrier. For example, for a carrier that only accommodates a single column of battery cells, its installation requirement is only the spacing of the battery cells in each column (that is, the above-mentioned row spacing), and there is no specific requirement for the column spacing, as long as batch handling can be achieved.

[0055] The carrier in this embodiment can accommodate two rows of good battery cells, so there are relatively precise requirements for the row spacing and column spacing. Therefore, the present invention does not impose specific restrictions on the preset spacing, as long as it can meet the requirements of the carrier for batch installation of battery cells.

[0056] Optionally, in some embodiments, a separate loading device may be provided to replace the above-mentioned loading robot 32, so as to install batches of good battery cells from the batch feeding device into the carrier.

[0057] like Figure 1 , Figure 2 As shown, the loading robot 32 has a loading frame, which includes a plurality of loading seats and a third adsorption component, each of which is connected to the third adsorption component to adsorb and fix the good battery cells to prevent the occurrence of position movement, thereby ensuring that the battery cells can be placed in the storage mechanism 3 and the loading robot 32 in a preset state after being positioned by the detection and positioning component 14, and finally installed in the carrier, thereby improving the accuracy of installation. Among them, the structure of the second adsorption component is the same as that of the first adsorption component.

[0058] In practical applications, batch feeding devices are suitable for multiple links in the battery cell production process. For example, before the battery cells undergo the vertical electroplating process, the battery cells need to be installed in a carrier. In this case, the batch feeding device can be used to inspect, classify and install the battery cells.
