Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a cylindrical battery code scanning system. Background Art

[0002] The current production line efficiency of front-shell batteries is generally between 15PPM (Pieces Per Minute) and 30PPM. With the development and introduction of cylindrical batteries, the efficiency requirement has been increased to 150PPM and above. According to conventional design schemes, it is possible to meet the production rhythm requirements by adding barcode scanners and corresponding blocking cylinders to the production line, but the corresponding hardware costs will increase exponentially. However, current battery production lines also usually have the goal of reducing costs. In order to achieve the cost reduction goal, the number of barcode scanners must be reduced. If the number of barcode scanners is reduced, there will be a risk of reduced scanning success rate and efficiency.

[0003] Therefore, it is urgent to propose a cylindrical battery scanning system that can meet production efficiency without increasing the number of scanners and has relatively low costs. Utility Model Content

[0004] The purpose of the utility model is to provide a cylindrical battery code scanning system, which can dynamically scan the cylindrical battery during transportation, meet production efficiency, do not require a new scanner, and has a relatively low cost.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The utility model discloses a cylindrical battery code scanning system, comprising: a transport device, the transport device is used to transport a support cup, the support cup is used to carry a cylindrical battery; a pitch-changing device, the pitch-changing device comprises a driving source and a pitch-changing screw, and the pitch of the pitch-changing screw gradually increases along the transport direction of the transport device; a code scanning device, along the transport direction of the transport device, the code scanning device is located downstream of the pitch-changing device; wherein: when the transport device transports the support cup through the pitch-changing device, the pitch-changing screw can cooperate with the support cup, and after passing through the pitch-changing screw, the distance between two adjacent support cups becomes larger.

[0007] The beneficial effects of the cylindrical battery scanning system of the present invention are as follows: in the actual working process, when the support cup has not passed through the pitch-changing device, the distance between the two adjacent support cups is small, which can improve the transportation efficiency of the transport device. When the transport device transports the support cup through the pitch-changing device, the pitch-changing screw can cooperate with the support cup, and after passing through the pitch-changing screw, the distance between the two adjacent support cups becomes larger. Then, when a support cup passes through the scanning device, the scanning device can directly scan the cylindrical battery on the support cup. Since the distance between the two adjacent support cups becomes larger at this time, when the previous cylindrical battery is being scanned, the next cylindrical battery has not yet moved to the scanning station, and there is no need to block it. The cylindrical battery scanning system realizes dynamic scanning of cylindrical batteries during transportation, which can meet production efficiency, does not require a new scanner, and does not require the use of a blocking cylinder in the prior art, and has a relatively low cost.

[0008] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

It should 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 of its components.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components.

[0016] The utility model discloses a cylindrical battery scanning system, referring to Figure 1 and Figure 2 As shown, the cylindrical battery code scanning system includes a transport device 100, a pitch-changing device 200, and a code scanning device 300. The transport device 100 is used to transport the tray 10, and the tray 10 is used to carry the cylindrical battery 20. The pitch-changing device 200 includes a driving source 220 and a pitch-changing screw 210. Along the transport direction of the transport device 100, the pitch of the pitch-changing screw 210 gradually increases. Along the transport direction of the transport device 100, the code scanning device 300 is located downstream of the pitch-changing device 200. When the transport device 100 transports the tray 10 through the pitch-changing device 200, the pitch-changing screw 210 can cooperate with the tray 10, and after passing through the pitch-changing screw 210, the distance between two adjacent trays 10 becomes larger. It can be understood that in the actual working process, when the support cup 10 has not passed through the pitch-changing device 200, the distance between the two adjacent support cups 10 is small, which can improve the transportation efficiency of the transportation device 100. When the transportation device 100 transports the support cup 10 through the pitch-changing device 200, the pitch-changing screw 210 can cooperate with the support cup 10, and after passing through the pitch-changing screw 210, the distance between the two adjacent support cups 10 becomes larger. Then, when a support cup 10 passes through the code scanning device 300, the code scanning device 300 can directly scan the cylindrical battery 20 on the support cup 10. Since the distance between the two adjacent support cups 10 becomes larger at this time, when the previous cylindrical battery 20 is scanning, the latter cylindrical battery 20 has not yet moved to the code scanning station, and there is no need to block it. Therefore, the cylindrical battery scanning system of this embodiment realizes dynamic scanning of the cylindrical battery 20 during transportation, which can meet production efficiency, and does not require a new scanner and does not require the use of the blocking cylinder in the prior art, and the cost is relatively low.

[0017] It should be noted that in the embodiments of the present invention, the transport device 100 can be a conveyor belt mechanism or a conveyor chain plate structure. The specific type of transport device 100 can be selected according to actual needs. The code scanning device 300 can be a brand and model that meets dynamic code scanning requirements, for example, a code scanning gun with a decoding efficiency of ≤0.3s.

[0018] refer to Figure 2 As shown, the cylindrical battery scanning system also includes a detection device 400. Along the transport direction of the transport device 100, the detection device 400 is located between the distance variable device 200 and the scanning device 300. The detection device 400 is electrically connected to the scanning device 300 and can send a signal to the scanning device 300 when the cup 10 and / or the cylindrical battery 20 are detected. It can be understood that in the actual working process, when the cup 10 transported by the transport device 100 moves to the position corresponding to the detection device 400, the detection device 400 can send a signal to the scanning device 300 when it detects the cup 10 and / or the cylindrical battery 20, and the scanning device 300 can start working to scan the code, thereby improving the reliability of the scanning work and reducing the occurrence of scanning failure or inaccurate scanning. In this embodiment, the detection device 400 is a photoelectric sensor, and the transmitting end 410 and the receiving end 420 of the photoelectric sensor are respectively located on both sides of the transport device 100. In actual operation, when the cup 10 transported by the transport device 100 moves to the position corresponding to the detection device 400, the light emitted by the transmitting end 410 is blocked by the cup 10 and the cylindrical battery 20, and the receiving end 420 cannot receive the light signal. At this time, a signal can be sent to the code scanning device 300. Of course, in other embodiments of the present invention, the detection device 400 can also select other devices capable of detecting position according to actual needs, such as infrared sensors and other structures, and is not limited to the photoelectric switch of this embodiment.

[0019] Optionally, the distance between the detection device 400 and the end of the variable pitch screw 210 near the code scanning device 300 ranges from 350 mm to 500 mm. The distance between the detection device 400 and the end of the variable pitch screw 210 near the code scanning device 300 can be 350 mm, 360 mm, 370 mm, 380 mm, 390 mm, 400 mm, 410 mm, 420 mm, 430 mm, 440 mm, 450 mm, 460 mm, 470 mm, 480 mm, 490 mm, or 500 mm. Of course, other values ​​between 350 mm and 500 mm can also be selected and are not limited to the above examples. If the distance between the detection device 400 and the end of the variable pitch screw 210 close to the scanning device 300 is too small, the scanning device 300 will have insufficient scanning time, increasing the probability of scanning failure or inaccurate scanning, and if the distance between the detection device 400 and the end of the variable pitch screw 210 close to the scanning device 300 is too large, the scanning efficiency will be reduced. In this embodiment, the distance between the detection device 400 and the end of the variable pitch screw 210 close to the scanning device 300 is controlled within the range of 350mm-500mm, which can reserve sufficient scanning time for the scanning device 300, ensure the stability of the scanning process, reduce the probability of scanning failure or inaccurate scanning, and help improve the scanning efficiency to meet the single-line production capacity needs.

[0020] Optionally, after the variable pitch screw 210, the distance between two adjacent support cups 10 is at least 100 mm. It is understandable that the distance between two adjacent support cups 10 is at least 100 mm, which can avoid the phenomenon of reducing the scanning yield rate due to the distance between two adjacent cylindrical batteries 20 on the transport device 100 being too small, thereby ensuring that the cylindrical battery scanning system of this embodiment can stably and reliably scan the cylindrical batteries 20.

[0021] Optionally, the scanning time of a single cylindrical battery 20 is 0.2s-1s, and the transport speed of the transport device 100 is greater than or equal to 0.5m / s. For example, according to the process requirement of 150ppm, the decoding of a single battery is required to be 0.4s. In this embodiment, the scanning time of a single cylindrical battery 20 is 0.4s, which can meet the process requirements, and according to the aforementioned variable pitch screw 210, the spacing between two adjacent cups 10 is at least 100mm, and it can be calculated that the transport speed of the transport device 100 is greater than or equal to 0.25m / s. In other words, the scanning time of a single cylindrical battery 20 is 0.4s, and the transport speed of the transport device 100 is greater than or equal to 0.25m / s, which can better meet the production capacity requirement of a single production line to achieve 150PPM. Of course, in other embodiments of the present invention, the scanning time of a single cylindrical battery 20 can be arbitrarily selected between 0.2s and 1s, and the transportation speed of the transportation device 100 can also be obtained by referring to the above calculation process, so as to make adjustments according to the actual single-line production capacity needs to ensure that the cylindrical battery scanning system of this embodiment can meet the actual single-line production capacity.

[0022] refer to Figure 2 As shown, the pitch-changing device 200 further includes a bracket 230, which is arranged in parallel with the transport device 100. Both ends of the pitch-changing screw 210 are rotatably connected to the bracket 230, and the drive source 220 is mounted on the bracket 230, and the power output shaft of the drive source 220 is connected to the end of the pitch-changing screw 210. It can be understood that compared to directly mounting the pitch-changing screw 210 and the drive source 220 on the transport device 100, the bracket 230 for supporting the pitch-changing screw 210 and the drive source 220 added in this embodiment allows the transport device 100 and the pitch-changing device 200 to be assembled separately during the production line assembly process, and then the assembled pitch-changing device 200 can be mounted on the frame of the transport device 100. This method of assembling the modules after subassembly is conducive to simplifying the assembly process of the cylindrical battery scanning system and improving the assembly efficiency of the cylindrical battery scanning system.

[0023] refer to Figure 2As shown, the cylindrical battery code scanning system further includes a guide device 500, which is arranged on at least one side of the transport device 100 in a direction perpendicular to the transport direction of the transport device 100. The guide device 500 stops at the cup 10 and provides guidance for the movement of the cup 10. It is understandable that in the actual working process, if the transport device 100 is transporting the cup 10, and the cup 10 is skewed, the cylindrical battery 20 will be skewed. In this way, when the cup 10 passes through the code scanning device 300, it is very easy to cause code scanning failure or code scanning errors. In this embodiment, by adding a guide device 500 to provide guidance for the transportation of the cup 10, the movement direction of the cup 10 can be limited, and the cup 10 can be prevented from being skewed during transportation, so that the cylindrical battery 20 is always transported in a posture, ensuring that the code scanning device 300 can stably and reliably scan the cylindrical battery 20, which is conducive to improving the working yield of the cylindrical battery code scanning system.

[0024] Optionally, in this embodiment, the guide device 500 is formed as a belt extending along the transport direction of the transport device 100. Using a belt as the guide device 500 will prevent the cylindrical battery 20 from being scratched during the stable guidance of the cup 10, thereby avoiding scratches on the outer wall of the cylindrical battery 20. Of course, in other embodiments of the present invention, the guide device 500 can also be other guiding components such as guide rails, and is not limited to belts.

[0025] Optionally, the variable pitch screw 210 is non-metallic. It will be appreciated that, during actual operation, when the drive source 220 drives the variable pitch screw 210 to rotate, the threads of the variable pitch screw 210 contact the cup 10, thereby driving the cup 10 to move. The variable pitch screw 210 being non-metallic prevents wear on the cup 10 or the cylindrical battery 20 when the variable pitch screw 210 drives the cup 10 to move, thereby preventing scratches on the outer wall of the cylindrical battery 20. The variable pitch screw 210 can be made of Teflon or other non-metallic materials.

[0026] Optionally, the linear speed of the variable pitch screw 210 is equal to the speed at which the transport device 100 transports the tray 10, and the initial pitch of the end of the variable pitch screw 210 away from the code scanning device 300 is equal to the initial spacing between two adjacent trays 10 on the transport device 100. It is understandable that in actual operation, when the tray 10 passes through the variable pitch screw 210, the variable pitch screw 210 and the transport device 100 synchronously drive the tray 10 to move, and control the linear speed of the variable pitch screw 210 to be equal to the speed at which the transport device 100 transports the tray 10, thereby avoiding the phenomenon of the tray 10 being skewed due to the difference in driving speeds between the two, thereby ensuring that the tray 10 can gradually increase the spacing from the adjacent tray 10 when passing through the variable pitch screw 210 and can ensure that it itself moves stably toward the code scanning device 300. The initial pitch of the variable pitch screw 210 at the end away from the code scanning device 300 is equal to the initial spacing between two adjacent cups 10 on the transport device 100, which can prevent the two adjacent cups 10 from synchronously entering the conveying range of the variable pitch screw 210 during transportation, thereby ensuring that the cups 10 can be transported stably.

[0027] Optionally, along the transport direction of the transport device 100 , the difference between two adjacent pitches of the variable-pitch screw 210 ranges from 4 mm to 8 mm. Specifically, the difference between two adjacent pitches of the variable pitch screw 210 can be 4mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm, 4.5mm, 4.6mm, 4.7mm, 4.8mm, 4.9mm, 5mm, 5.1mm, 5.2mm, 5.3mm, 5.4mm, 5.5mm, 5.6mm, 5.7mm, 5.8mm, 5.9mm, 6mm, 6.1mm, 6.2mm, 6.3mm, 6.4mm, 6.5mm, 6.6mm, 6.7mm, 6.8mm, 6.9mm, 7mm, 7.1mm, 7.2mm, 7.3mm, 7.4mm, 7.5mm, 7.6mm, 7.7mm, 7.8mm, 7.9mm, or 8mm. The difference between two adjacent pitches of the variable pitch screw 210 can also be other values ​​within the range of 4mm-8mm, and is not limited to the above examples. If the difference between two adjacent pitches of the variable pitch screw 210 is too small, the distance between two adjacent cups 10 will be insufficient after the variable pitch transportation of the variable pitch screw 210, thereby affecting normal code scanning. If the difference between two adjacent pitches of the variable pitch screw 210 is too large, the distance between two adjacent cups 10 will be too large after the variable pitch transportation of the variable pitch screw 210, reducing the code scanning efficiency. In this embodiment, the difference between two adjacent pitches of the variable pitch screw 210 is in the range of 4mm-8mm, which can ensure that the distance between two adjacent cups 10 after the variable pitch transportation of the variable pitch screw 210 is sufficient to ensure normal code scanning and can also ensure code scanning efficiency.
