Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a sorting device, a sorting method and a battery production line. Background Art

[0002] During the battery production process, especially on high-speed production lines, the battery shell dimensions may deviate due to processing accuracy issues. Dimension measurement is a necessary step in the product production process and a key link in ensuring battery quality. Every battery in the production process must undergo rigorous dimensional measurement to determine whether it meets processing requirements. The result of this measurement not only determines whether the battery itself is qualified but also affects subsequent battery reprocessing. Therefore, measuring the shell dimensions and sorting the produced batteries is an indispensable task for enterprises. At the same time, online detection of battery shell dimensions and sorting of non-conforming products during the production process are also important for providing feedback and guidance to the production process, thereby improving product quality.

[0003] In existing methods, the measurement of battery shell dimensions is mostly done manually. Operators directly use measuring tools to perform inspections and determine whether the batteries are qualified according to company standards. This is not only time-consuming and labor-intensive, but also costly and inefficient, and is prone to missed inspections. At the same time, when unqualified products are detected, the production line needs to be stopped and the unqualified products need to be manually sorted out and collected. This sorting method is no longer applicable to the current automated production lines with greatly improved production speeds.

[0004] Therefore, there is an urgent need to provide a new type of sorting device, sorting method and battery production line to solve the above technical problems in the prior art. Summary of the Invention

[0009] Optionally, the transfer mechanism includes a fixed bracket, a first driving member and a push plate, the first driving member is arranged on the fixed bracket, the output end of the first driving member is connected to the push plate, when the detection position where the unqualified products to be sorted are fixed moves to the closest point to the waste tray, the push plate is located on the line connecting the center of the sorting tray and the center of the waste tray and is arranged at the end of the unqualified products to be sorted away from the waste tray, and the first driving member is used to drive the push plate to approach the waste tray along the first direction.

[0010] Optionally, the fixed bracket is further provided with a second driving member, and the output end of the second driving member is provided with the first driving member. The second driving member can drive the first driving member to approach or move away from the unqualified product to be sorted along a second direction, and the second direction is perpendicular to the first direction.

[0011] Optionally, the bottom of the product to be sorted is clamped on a fixing fixture, and the fixing fixture can be fixedly connected with the detection position or the material receiving position respectively.

[0012] Optionally, the sorting device further includes a stabilizing plate, which is arranged between the sorting tray and the waste tray and opposite to the transfer mechanism. The stabilizing plate extends along the second direction, and the stabilizing plate can abut against the fixing fixture carrying the unqualified products to be sorted, so that the fixing fixture can be clamped between the stabilizing plate and the push plate.

[0013] Optionally, the circumferential outer wall of the fixing fixture is provided with an annular clamping groove, and at least a portion of the stabilizing plate can be accommodated in the annular clamping groove.

[0014] Optionally, the detection mechanism includes a plurality of visual cameras, and the plurality of visual cameras are arranged in a one-to-one correspondence at the plurality of detection positions, and the plurality of visual cameras are respectively communicatively connected to the transfer mechanism.

[0015] Another object of the present invention is to provide a sorting method, which uses a sorting device as described in any of the above schemes, including the following steps: S1, the first conveyor line conveys the above-mentioned products to be sorted to the above-mentioned sorting disk, and the above-mentioned products to be sorted are fixed to the above-mentioned detection position; S2, when the above-mentioned sorting disk rotates, the above-mentioned detection mechanism starts to detect whether the above-mentioned products to be sorted installed at the above-mentioned detection position are qualified, if qualified, execute step S3, if unqualified, execute step S4; S3, the above-mentioned sorting disk rotates, so that the products to be sorted installed at the above-mentioned detection position move to the second conveyor line, the above-mentioned detection position releases the above-mentioned products to be sorted and transports them to the next workstation by the second conveyor line; S4, the above-mentioned sorting disk rotates, so that the unqualified products to be sorted move to the above-mentioned transfer mechanism, the above-mentioned transfer mechanism moves the unqualified products to be sorted to the receiving position of the above-mentioned waste disk, and after the above-mentioned waste disk rotates, the unqualified products to be sorted are released from the receiving position to the waste collection mechanism.

The sorting disc and the waste disc used in the sorting device are both circular motion structures. Compared with the linear motion structure, the structure is simpler, the footprint is smaller, and the production cost can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0033] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0035] The first direction described in this embodiment is Figure 1 The X direction shown in is the direction of the line connecting the center of the sorting tray 100 and the center of the waste tray 400, and the second direction is Figure 4 The Y direction shown in the figure is a direction perpendicular to the line connecting the center of the sorting tray 100 and the center of the waste tray 400. The first direction is perpendicular to the second direction, and both are horizontal directions.

[0036] like Figure 1 As shown, the sorting device includes a sorting disc 100, a detection mechanism, a waste disc 400 and a transfer mechanism 300. The sorting disc 100 can rotate around its own axis, and the sorting disc 100 is provided with a plurality of detection positions 110 along the circumference, and the detection positions 110 are configured to selectively fix or release the product to be sorted 10; the detection mechanism is used to detect whether the size parameters of the product to be sorted 10 are qualified; the waste disc 400 can rotate around its own axis, and the waste disc 400 is provided with a plurality of material receiving positions 410 along the circumference, and the material receiving positions 410 are configured to selectively fix or release the unqualified product to be sorted 10; the transfer mechanism 300 is provided between the sorting disc 100 and the waste disc 400, and the transfer mechanism 300 is used to transport the unqualified product to be sorted 10 from the detection position 110 to the material receiving position 410.

[0037] The sorting device in this embodiment uses a plurality of detection positions 110 of the sorting disk 100 to install the products to be sorted 10 in a one-to-one correspondence. The detection mechanism is used to detect the products to be sorted 10 while the sorting disk 100 rotates, and unqualified products are selected, while qualified products are transported to the next workstation while the sorting disk 100 rotates; when unqualified products are detected, the transfer mechanism 300 arranged between the sorting disk 100 and the waste disk 400 is started, thereby transporting the unqualified products to be sorted 10 from the detection position 110 to the material receiving position 410, and the waste disk 400 continues to rotate after receiving the unqualified products to be sorted 10, thereby releasing the products to be sorted 10 at the preset position, completing the collection and processing of unqualified products. The sorting disc 100 and the waste disc 400 in this embodiment are always in a rotating state, and can continuously transport the products to be sorted 10, so as to detect the products to be sorted 10 online in real time. Even if unqualified products are detected, there is no need to stop the machine to remove the products to be sorted 10. Instead, the transfer mechanism 300 transports the unqualified products to the waste disc 400 online, and can sort and reject unqualified products when transporting the products to be sorted 10, thereby improving the sorting efficiency. The sorting disc 100 and the waste disc 400 used in the sorting device are both circular motion structures. Compared with the linear motion structure, the structure is simpler, occupies a smaller area, and can reduce production costs.

[0038] Optionally, the inspection mechanism described herein includes a plurality of visual cameras 200, each of which is disposed in a one-to-one correspondence at each of the inspection positions 110, and each of which is in communication with the transfer mechanism 300. Using the visual cameras 200 to inspect the products 10 to be sorted mounted at the inspection positions 110 in a one-to-one correspondence allows the products 10 to be inspected while the sorting disc 100 rotates, thereby improving inspection efficiency. Furthermore, automated inspection using the visual cameras 200 is more efficient, which will not be further elaborated herein.

[0039] In this embodiment, six visual cameras 200 are provided, one corresponding to each inspection station 110, and are evenly spaced. This will not be described in detail here. Of course, a single visual camera 200 can also be used for inspection, but the visual camera 200 must always be aligned in one direction. When a particular inspection station 110 passes by the visual camera 200, the product 10 to be sorted is inspected. Although fewer visual cameras 200 are used, an additional fixing mechanism that does not rotate synchronously with the sorting disk 100 is required, making the structure more complex. This will not be described in detail here.

[0040] Furthermore, the central axis of the above-mentioned sorting tray 100 and the central axis of the above-mentioned waste tray 400 are spaced apart and arranged in parallel, and the above-mentioned sorting tray 100 and the above-mentioned waste tray 400 have the same height; wherein the above-mentioned transfer mechanism 300 is located on the line connecting the center of the above-mentioned sorting tray 100 and the center of the above-mentioned waste tray 400. When the unqualified product to be sorted 10 is detected, since the transfer mechanism 300 is located on the center line connecting the sorting disk 100 and the waste disk 400, when the sorting disk 100 and the waste disk 400 rotate, the detection position 110 where the unqualified product to be sorted 10 is fixed moves to the closest point to the waste disk 400, and the transfer mechanism 300 transports the unqualified product to be sorted 10 to the receiving position 410 closest to the sorting disk 100. At this time, the movement stroke of the unqualified product to be sorted 10 driven by the transfer mechanism 300 is the shortest, which improves the sorting speed and sorting efficiency, and makes the structure of the sorting device more compact, occupies less space, and saves the space cost of the production plant.

[0041] In this embodiment, the preset distance between the sorting plate 100 and the waste plate 400 is no greater than the diameter of a product 10 to be sorted. It can shorten the movement stroke of the transfer mechanism 300 as much as possible while avoiding collision between the sorting plate 100 and the waste plate 400. It will not be repeated here.

[0042] like Figure 2 and Figure 3 As shown, the transfer mechanism 300 includes a fixed bracket 330, a first driving member 320, and a push plate 310. The first driving member 320 is disposed on the fixed bracket 330. The output end of the first driving member 320 is connected to the push plate 310. When the detection position 110, on which the unqualified product to be sorted 10 is fixed, moves to the position closest to the waste tray 400, the push plate 310 is located on the line connecting the center of the sorting tray 100 and the center of the waste tray 400 and is disposed at the end of the unqualified product to be sorted 10 away from the waste tray 400. The first driving member 320 is used to drive the push plate 310 to approach the waste tray 400 in a first direction. The first driving member 320 here is specifically selected as a linear cylinder, which can perform linear reciprocating motion, so that the push plate 310 can smoothly push the unqualified product to be sorted 10 to the receiving position 410 of the waste tray 400. Not only is the mechanism simple and low-cost, but the degree of automation is also higher.

[0043] Furthermore, the fixed bracket 330 is also provided with a second drive member 340, the output end of which is provided with the first drive member 320. The second drive member 340 is capable of driving the first drive member 320 toward or away from the unqualified products 10 to be sorted along a second direction, the second direction being perpendicular to the first direction. That is, the push plate 310 in this embodiment is not originally located on the center line connecting the sorting disc 100 and the waste disc 400. Only after an unqualified product is detected is the push plate 310 pushed to the detection position 110 where the unqualified product is located. This prevents the products 10 to be sorted from colliding with the push plate 310 during the rotation of the sorting disc 100, making the structure of the sorting device more rational and enabling continuous movement without being affected, further improving the sorting efficiency and reliability of the device.

[0044] like Figure 4 and Figure 5 As shown, the bottom of the product to be sorted 10 is clamped to the fixing fixture 11, which can be respectively fixedly connected to the detection position 110 or the receiving position 410. In this embodiment, the product to be sorted 10 is a cylindrical shell of a cylindrical battery, and the fixing fixture 11 used is also cylindrical, which can more firmly fix the product to be sorted 10 to the detection position 110 or the receiving position 410, improving the stability of the fixation.

[0045] Optionally, the sorting device further includes a stabilizing plate 500, which is arranged between the sorting tray 100 and the waste tray 400 and opposite to the transfer mechanism 300. The stabilizing plate 500 is extended along the second direction. The stabilizing plate 500 can abut against the fixing fixture 11 carrying the unqualified product to be sorted 10, so that the fixing fixture 11 can be clamped between the stabilizing plate 500 and the push plate 310. When the push plate 310 pushes the unqualified product to be sorted 10 toward the receiving position 410 of the waste tray 400, its fixing clamp 11 is not in contact with the receiving position 410 and the detection position 110 for a period of time. At this time, the product to be sorted 10 will be skewed and cannot be smoothly fixed on the receiving position 410. However, under the clamping action of the stabilizing plate 500 and the push plate 310, the product to be sorted 10 can be clamped and fixed, thereby being smoothly transported to the receiving position 410, further improving reliability.

[0046] In this embodiment, the stabilizing plate 500 is fixed on the stabilizing bracket 510 and hinged to the stabilizing bracket 510. It is subjected to a pre-tightening force opposite to the thrust of the push plate 310, thereby being able to provide a certain thrust and play a clamping function with the push plate 310. It will not be repeated here.

[0047] Furthermore, the circumferential outer wall of the fixing fixture 11 is provided with an annular snap-fitting groove 12, and at least a portion of the stabilizing plate 500 can be accommodated in the annular snap-fitting groove 12. The provision of the annular snap-fitting groove 12 not only serves to clamp the stabilizing plate 500, thereby making the connection between the stabilizing plate 500 and the fixing fixture 11 tighter, but also allows the upper and lower walls of the stabilizing plate 500 to face the upper and lower inner side walls of the annular snap-fitting groove 12 to play a vertical supporting role, making the conveying and transfer process more stable and reliable, thereby further preventing unqualified products 10 to be sorted from tilting during transportation, and thus allowing them to be smoothly fixed to the receiving position 410, further improving the sorting efficiency.

[0048] This embodiment also provides a sorting method, which uses the sorting device as described in any of the above schemes, including the following steps: S1, the first conveyor line conveys the above-mentioned product 10 to the above-mentioned sorting disk 100, and the above-mentioned product 10 to be sorted is fixed to the above-mentioned detection position 110; S2, when the above-mentioned sorting disk 100 rotates, the above-mentioned detection mechanism starts to detect whether the above-mentioned product 10 to be sorted installed in the above-mentioned detection position 110 is qualified, if qualified, step S3 is executed, if unqualified, step S4 is executed; S3, the above-mentioned sorting disk 100 rotates so that the above-mentioned product 10 to be sorted is fixed to the above-mentioned detection position 110; The product 10 to be sorted installed at the detection position 110 moves to the second conveyor line, and the detection position 110 releases the product 10 to be sorted and transports it to the next workstation by the second conveyor line; S4, the sorting disk 100 rotates, so that the unqualified product 10 to be sorted moves to the transfer mechanism 300, and the transfer mechanism 300 moves the unqualified product 10 to be sorted to the receiving position 410 of the waste tray 400. After the waste tray 400 rotates, the unqualified product 10 to be sorted is released from the receiving position 410 to the waste collection mechanism.

[0049] The sorting method in this embodiment uses the above-mentioned sorting device, thereby having all the beneficial effects of the sorting device described in any of the above schemes. Specifically, the sorting disc 100 and the waste disc 400 are always in a rotating state, which can continuously transport the products to be sorted 10, thereby detecting the products to be sorted 10 online in real time. Even if unqualified products are detected, there is no need to stop the machine to remove the products to be sorted 10. Instead, the transfer mechanism 300 transports the unqualified products to the waste disc 400 online, and the waste disc 400 transfers them to the waste collection mechanism. In this way, unqualified products can be sorted and removed when the products to be sorted 10 are transported, thereby improving the sorting efficiency. The sorting disc 100 and the waste disc 400 used in the sorting device are both circular motion structures. Compared with the linear motion structure, its structure is simpler, occupies a smaller area, and can reduce production costs.

[0050] The present invention further provides a battery production line comprising a sorting device as described in any of the above-mentioned embodiments. This battery production line has all the benefits of the sorting device described in any of the above-mentioned embodiments, specifically improving the efficiency of battery casing sorting, thereby improving battery production efficiency. Furthermore, the production plant required for this production line requires a smaller floor space and lowers plant costs. This will not be further described here.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
