Description

Technical Field

[0001] The present application relates to the technical field of lithium battery manufacturing, and in particular to a coding device. Background Art

[0002] In the production and assembly process of lithium battery modules, it is crucial to accurately manage and trace the information of each battery cell and its battery module. Each battery cell and battery module is engraved with a unique QR code to record its detailed performance parameters. This practice not only ensures the traceability of product quality, but also provides convenience for subsequent maintenance and after-sales service.

[0003] The traditional data processing method is to first code the battery cells and end plates one by one with QR codes before the battery cells are assembled into battery modules, and then complete the detection of the corresponding performance parameters of each battery cell at multiple subsequent inspection stations and scan and enter them. That is, the detected performance parameters of the battery cell and the battery cell identification (uniquely confirmed by the QR code) are bound and stored, and finally the QR code on the end plate of the battery module is matched with the corresponding information of all the battery cells, so as to achieve the effect of querying the performance parameters of all the battery cells in the corresponding battery module by scanning the QR code on the end plate.

[0004] However, the process from the initial loading of the battery cells to the final assembly with the end plate into a battery module requires multiple rounds of inspection and operation, including the removal and replacement of unqualified battery cells. In this complex process, the information of the rejected unqualified battery cells needs to be deleted, and the information of the replaced new battery cells needs to be re-entered. This series of steps not only requires the addition of scanning equipment, but also greatly increases the risk of error. In addition, the battery cells need to be transferred, processed and scanned many times throughout the process, and it may be difficult to read due to damage to the QR code or the angle of the battery cell. Summary of the invention

[0005] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application provides a coding device to solve the problem that in the prior art, during the process of cell information entry and lithium battery module QR code coding, the battery cell needs to be transferred, processed and scanned multiple times, which easily leads to damage to the QR code or difficulty in reading due to the angle of the battery cell, and the cost is increased due to the addition of scanning equipment.

[0006] The purpose of this application can be achieved through the following technical solutions:

[0007] The present application provides a coding device, which is used in lithium battery module assembly equipment. The coding device includes a code scanning mechanism, a laser coding mechanism and a driving mechanism. The code scanning mechanism and the laser coding mechanism are both installed on the driving end of the driving mechanism. The driving mechanism is used to drive the code scanning mechanism to translate along the arrangement direction of the two-dimensional code of the battery cell, so as to scan the two-dimensional code containing the battery cell information one by one and collect the information of all the battery cells; after collecting the information of all the battery cells, the driving mechanism is also used to drive the laser coding mechanism to move to the opposite side of the end plate, so as to engrave the lithium battery module two-dimensional code on the surface of the end plate, and the lithium battery module two-dimensional code contains the information of all the battery cells in the same lithium battery module collected by the code scanning mechanism.

[0008] By integrating the code scanning mechanism and the coding mechanism on the same driving mechanism, the entire device can complete the QR code scanning and information entry of the assembled lithium battery module, as well as the subsequent QR code printing work, at a single station, without the need to transfer the lithium battery module between different stations, simplifying the production process and improving work efficiency. More importantly, since the battery cells have been screened and assembled before entering this device, ensuring that the quality of all battery cells meets the standards, it is no longer necessary to remove or replace unqualified battery cells during the information entry process. This not only avoids the information entry errors that may occur in traditional multi-station operations, but also greatly reduces the complexity of battery cell information management and ensures the consistency and accuracy of the data. In addition, this application chooses to print the QR code directly on the end plate of the assembled lithium battery module, rather than pre-printing it on an independent component and then participating in the assembly. Such a design avoids the physical wear and tear that the QR code may encounter during the assembly process, ensures the clarity and readability of the QR code, and thus improves the quality and reliability of the final product.

[0009] Optionally, the driving mechanism includes a first translation module and a second translation module, the second translation module is installed on the driving end of the first translation module, the code scanning mechanism and the laser coding mechanism are both installed on the driving end of the second translation module, the first translation module is used to simultaneously drive the code scanning mechanism and the laser coding mechanism to translate along the first horizontal direction, the second translation module is used to simultaneously drive the code scanning mechanism and the laser coding mechanism to translate along the second horizontal direction, and the first horizontal direction is perpendicular to the second horizontal direction.

[0010] The first translation module and the second translation module cooperate with each other to realize precise translation of the scanning mechanism and the laser coding mechanism in two vertical horizontal directions, and can accurately locate the coding position of the battery cell QR code and the end plate, thereby improving the accuracy of coding and scanning, further optimizing the operating accuracy of the device, and reducing problems such as scanning failure or coding errors caused by position deviation.

The lifting module is used to drive the laser coding mechanism to rise and fall.

[0012] The setting of the lifting module increases the movement dimension in the height direction for the laser coding mechanism, so that the laser coding mechanism can move to the opposite side of the end plate for coding operation, and can also move to the top of the lithium battery module to follow the scanning mechanism to move horizontally along the first horizontal direction and the second horizontal direction, thereby meeting the diverse operation requirements of the laser coding mechanism.

[0013] Optionally, the laser coding mechanism includes a distance measuring sensor, a laser coding device and a verification code scanner which are sequentially arranged on the second mounting frame along the second horizontal direction at intervals, wherein:

[0015] The distance sensor measures the distance to the end plate before laser coding, and can adjust the position of the coder according to the measurement result to ensure that the distance between the laser coder and the end plate is in the best state each time coding, thereby ensuring the consistency and clarity of coding and improving the success rate and quality of coding. The verification scanner scans the lithium battery module QR code after coding, and can promptly detect possible errors in the coding process, such as incomplete or incorrect QR code information, etc., to ensure the accuracy of the lithium battery module QR code information and provide reliable guarantee for subsequent product information traceability.

[0016] Optionally, the first mounting plate is provided with a first waist hole for adjusting the mounting height of the ranging sensor and a first arc hole for adjusting the mounting angle of the ranging sensor.

[0017] The first waist hole and the first arc hole on the first mounting plate provide the distance measuring sensor with the function of adjusting the installation height and angle, so that it can be accurately adjusted according to the actual working conditions to ensure the accuracy of the distance measurement, thereby better ensuring the quality and consistency of laser coding.

[0018] Optionally, the second mounting plate is provided with a second waist hole for adjusting the installation height of the verification scanner, a third waist hole for adjusting the horizontal installation position of the verification scanner, and a second arc hole for adjusting the installation angle of the verification scanner.

[0019] The second waist hole, the third waist hole and the second arc hole on the second mounting plate provide multi-dimensional adjustment functions for the verification scanner, including height, horizontal position and angle, so that it can scan the lithium battery module QR code more accurately, effectively improve the accuracy and reliability of the verification, and ensure the quality of the coding information.

The cell code scanner is adjustably mounted on the driving end of the second translation module via the third mounting frame.

[0022] The code scanning mechanism and the laser coding mechanism are symmetrically arranged on both sides of the second translation module along the first horizontal direction, which helps to maintain the balance and stability of the device during operation, reduce the vibration and displacement that may be caused by structural asymmetry, and improve the accuracy of code scanning and coding. The mounting holes on the third mounting frame make the position of the battery cell code scanner adjustable, which can adapt to the position and angle differences of different battery cell QR codes, improve the success rate and accuracy of code scanning, and ensure the effective collection of battery cell information.

[0023] Optionally, the coding device also includes a dust suction mechanism, which includes a dust suction pipe and a dust suction box arranged at one end of the dust suction pipe, the first end of the dust suction box is connected to the dust suction pipe, and the second end of the dust suction box is provided with two opposite avoidance holes. The laser emitted by the laser coding mechanism passes through the avoidance holes and acts on the end plate of the lithium battery module. A dust suction chamber surrounding the two avoidance holes is formed in the dust suction box, the dust suction pipe is connected to the dust suction chamber, and the dust suction pipe removes waste generated around the avoidance holes during the coding process through the dust suction chamber.

[0024] The dust suction mechanism removes waste materials during the coding process, keeps the working environment clean, reduces the pollution and erosion of the internal structure of the equipment by waste materials, extends the service life of the equipment, and prevents waste materials from affecting the normal coding operation, thereby improving the stability and reliability of the production process.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] See also Figure 1-3 As shown, in some embodiments, the present application provides a coding device, which has wide applicability and can be applied to lithium battery module 600 assembly equipment and can also serve other equipment.

[0040] The coding device includes a code scanning mechanism 100, a laser coding mechanism 200 and a driving mechanism 300, wherein the code scanning mechanism 100 and the laser coding mechanism 200 are both installed on the driving end of the driving mechanism 300, thereby forming a closely coordinated organic whole.

[0041] The driving mechanism 300 has a precise translation function and can stably move the code scanning mechanism 100 along the arrangement direction of the battery cell QR code in the lithium battery module 600. The code scanning sensor in the code scanning mechanism 100 is highly sensitive and can quickly and accurately identify the QR code on the battery cell and transmit the information to the control system of the device for storage. For example, when the QR code of a battery cell is scanned, the system will record key information such as its voltage, capacity, and production date. After completing the information collection of all battery cells, the driving mechanism 300 will quickly switch the working mode, drive the laser coding mechanism 200 to move accurately to the opposite side of the end plate, and print out the lithium battery module 600 QR code containing all the previously collected battery cell information in the same lithium battery module 600 on the surface of the end plate, ensuring that all battery cell information of the entire lithium battery module 600 can be fully obtained by scanning the QR code later.

[0042] See also Figure 2 As shown, in one embodiment, the driving mechanism 300 includes a first translation module 301 and a second translation module 302. The second translation module 302 is firmly mounted on the driving end of the first translation module 301, while the code scanning mechanism 100 and the laser coding mechanism 200 are jointly mounted on the driving end of the second translation module 302. The main function of the first translation module 301 is to realize the smooth translation operation of the code scanning mechanism 100 and the laser coding mechanism 200 in the first horizontal direction, while the second translation module 302 focuses on precise position adjustment in the second horizontal direction perpendicular to the first horizontal direction. The two cooperate with each other to ensure high-precision positioning during the code scanning and coding operations. Among them, the first horizontal direction is Figure 1 The X-axis direction shown in the figure, the second horizontal direction is Figure 1 The Y-axis direction shown in .

[0043] Specifically, when performing a coding operation on a lithium battery module 600 having a specific size and layout, first, the first translation module 301 is started according to a preset program. After startup, the first translation module 301 drives the code scanning mechanism 100 and the laser coding mechanism 200 to move rapidly in the first horizontal direction until they approach the approximate area where the battery cell QR code is located.

[0044] Subsequently, the second translation module 302 starts to work and synchronously adjusts the positions of the code scanning mechanism 100 and the laser coding mechanism 200 to ensure that the code scanning mechanism 100 can accurately scan the two-dimensional code on the battery cell when moving along the first horizontal direction.

[0045] After the position adjustment is completed, the first translation module 301 continues to play its role, and drives the code scanning mechanism 100 and the laser coding mechanism 200 to move smoothly in the first horizontal direction again. In this process, the code scanning mechanism 100 will accurately identify the two-dimensional codes on the top of the battery cells located in the first horizontal direction one by one.

[0046] It is particularly noteworthy that when the battery cells are arranged in multiple rows along the second horizontal direction, once the code scanning mechanism 100 completes the recognition of the QR code of one row of battery cells, the second translation module 302 will further adjust the positions of the two to ensure that the code scanning mechanism 100 can accurately identify the QR code on the next row of battery cells when it subsequently moves along the first horizontal direction, thereby ensuring that the QR code information of the entire lithium battery module 600 can be collected completely and accurately.

[0047] See also Figure 1 and Figure 2 As shown, in a possible implementation, the layout and structure of the first translation module 301 and the second translation module 302 are as follows:

[0048] The first translation module 301 is arranged below the second translation module 302, and a guide rail 303 is arranged in parallel on one side of the first translation module 301. One end of the second translation module 302 is firmly fixed on the driving end of the first translation module 301, and the other end thereof is slidably connected to the guide rail 303 through a slider. Such a design structure is intended to ensure that when the first translation module 301 drives the second translation module 302 to move, the second translation module 302 can slide smoothly along the guide rail 303, thereby significantly enhancing the stability of the entire translation process and ensuring the accuracy of position adjustment during code scanning and coding operations.

[0049] Further, when selecting the driving structure of the first translation module 301 and the second translation module 302, there are multiple feasible solutions. Among them, one can be selected from the linear driving structures such as the lead screw nut structure, the synchronous belt transmission structure and the magnetic suspension linear motor driving mechanism 300 as the driving mode of the first translation module 301 and the second translation module 302. These different driving structures have their own characteristics. For example, the lead screw nut structure has the advantages of high precision and high rigidity, the synchronous belt transmission structure can achieve a faster transmission speed, and the magnetic suspension linear motor driving mechanism 300 can provide higher speed and precision. In practical applications, the most suitable linear driving structure can be selected according to specific production requirements, cost budget, precision requirements, equipment performance and other factors to ensure that the first translation module 301 and the second translation module 302 can move in a straight line or a broken line when driving the code scanning mechanism 100 and the laser coding mechanism 200, so as to meet the translation operation requirements in different scenarios and provide stable, efficient and accurate translation function support for the code scanning and coding operations of the lithium battery module 600.

[0050] See also Figure 1-3As shown, in one embodiment, the driving mechanism 300 includes a lifting module 304, which is stably mounted on the driving end of the second translation module 302 through a first mounting frame 305 with a reasonable structure. At the same time, the laser coding mechanism 200 is mounted on the driving end of the lifting module 304 through a special second mounting frame 306. The core function of the lifting module 304 is to give the laser coding mechanism 200 the ability to move accurately in the vertical direction. Figure 1 The Z-axis direction is shown in the figure to meet its diverse operational requirements, that is, not only the coding operation needs to be completed on the opposite side of the end plate, but also the translation operation needs to be performed following the scanning mechanism 100.

[0051] Specifically, when processing the lithium battery module 600, considering that the laser coding mechanism 200 has a multi-tasking characteristic, it is necessary to perform coding operations on the opposite side of the end plate and to follow the scanning mechanism 100 to move horizontally along the first horizontal direction and the second horizontal direction. Therefore, the entire operation process is as follows:

[0052] First, before the laser coding mechanism 200 follows the code scanning mechanism 100 to perform a translation operation, the lifting module 304 will lift the laser coding mechanism 200 above the lithium battery module 600. The purpose of this is to avoid the laser coding mechanism 200 interfering with the translation operations in the first horizontal direction and the second horizontal direction during the translation process.

[0053] After that, when the code scanning mechanism 100 completes the scanning of the battery cell QR code, the first translation mechanism and the second translation mechanism will move the laser coding mechanism 200 to the upper side of the lithium battery module 600. Then, the lifting module 304 will accurately drive the laser coding mechanism 200 to descend to the set position, ensuring that the laser coding mechanism 200 is located on the end plate side of the lithium battery module 600 and opposite to it, so as to prepare for the subsequent printing of the lithium battery module 600 QR code containing all the battery cell information in the same lithium battery module 600 on the end plate, ensure the smooth progress of the coding operation, and realize the complete processing flow of the entire lithium battery module 600 information.

[0054] In a possible implementation, the lifting module 304 can be selected from a linear lifting structure such as a screw nut lifting structure, a cylinder driven lifting structure, an electric push rod lifting structure, a hydraulic lifting structure, etc. In practical applications, the selection can be based on specific application scenarios, load requirements, accuracy requirements, cost budgets, and operating speeds of the equipment, and is not specifically limited here.

[0055] See also Figure 3-5 As shown, in one embodiment, the laser coding mechanism 200 includes a distance measuring sensor (not shown), a laser coding device 201 and a verification code scanner 202 which are sequentially arranged on the second mounting frame 306 along the second horizontal direction, wherein:

[0056] The laser coder 201 is fixedly mounted on the second mounting frame 306, the distance sensor is adjustably mounted on the second mounting frame 306 through the first mounting plate 203 and is located on the first side of the laser coder 201, the distance sensor is used to measure the distance between the laser coder 201 and the end plate before the laser coder 201 codes, the verification scanner 202 is adjustably mounted on the second mounting frame 306 through the second mounting plate 204 and is located on the second side of the laser coder 201, the verification scanner 202 is used to scan the two-dimensional code of the lithium battery module 600 after the laser coder 201 codes to determine whether the two-dimensional code of the lithium battery module 600 is qualified.

[0057] Specifically, when performing a coding operation, the operation process is as follows:

[0058] First, before the coding operation begins, the height and angle of the distance measuring sensor are precisely adjusted using the first mounting plate 203 to ensure that it is in a suitable measuring state so that the distance can be accurately measured later. The verification scanner 202 is adjusted to the optimal scanning position using the second mounting plate 204 to ensure the successful scanning operation.

[0059] Next, during the coding operation, the second horizontal module starts to move the distance sensor to the opposite side of the end plate where the coding is required, and then the distance sensor is started to measure the distance between it and the end plate, and transmit the measured data to the control system. The control system uses the data as a reference to adjust the distance of the laser coder 201 relative to the end plate along the first horizontal direction to ensure that it is in the best coding position.

[0060] Afterwards, the second horizontal module is driven again to move the laser coder 201 to the opposite side of the desired coding position of the end plate, and the laser coder 201 performs coding operation on the end plate according to the collected battery cell information.

[0061] After the coding operation is completed, the second horizontal module continues to drive the verification scanner 202 to move to the opposite side of the required coding position of the end plate, and the verification scanner 202 is then started to scan the two-dimensional code of the lithium battery module 600.

[0062] During the scanning process, if the scanning result of the verification scanner 202 is consistent with the preset information, it indicates that the coding is successful; otherwise, if the information is found to be incorrect, the system will immediately issue an alarm and make corresponding adjustments to ensure the accuracy of the coding information.

[0063] In one possible implementation, the distance measuring sensor (not shown), the laser coder 201 and the verification code scanner 202 are arranged in sequence along the second horizontal direction. This layout enables the second translation module 302 to move in the same direction during operation, so that the distance measuring sensor, the laser coder 201 and the verification code scanner 202 can be moved to the opposite side of the coding position of the end plate in sequence. Through such a layout and movement method, not only can the continuity of the operation be guaranteed, but also a series of operations such as distance measurement, coding and verification code scanning can be completed in an orderly manner, ensuring the smooth progress of the entire coding process, and providing convenience and accuracy for subsequent coding operations.

[0064] In a possible implementation, a first waist hole (not shown) for adjusting the installation height of the distance sensor and a first arc hole (not shown) for adjusting the installation angle are carefully designed on the first installation plate 203. The distance sensor is fixedly mounted on the first installation plate 203 in a specific mounting manner. This structure enables the distance sensor to utilize the adjustment functions of the first waist hole and the first arc hole to achieve precise adjustment of the height and angle on the second mounting bracket 306, ensuring that its measurement light can be vertically irradiated onto the end plate, further improving the accuracy and reliability of the measurement.

[0065] In a possible implementation, the second mounting plate 204 is reasonably provided with a second waist hole (not shown) for adjusting the installation height of the verification scanner 202, a third waist hole (not shown) for adjusting the horizontal installation position, and a second arc hole 205 for adjusting the installation angle. The verification scanner 202 is fixedly connected to the second mounting plate 204 through a specific connection structure. With the adjustment function of these waist holes and arc holes, the verification scanner 202 can achieve multi-dimensional precise adjustment on the second mounting bracket 306, ensuring that the scanning light can accurately cover the two-dimensional code area, improving the accuracy and reliability of verification, and ensuring the coding quality.

[0066] See also Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, the code scanning mechanism 100 and the laser coding mechanism 200 are symmetrically installed on both sides of the second translation module 302 along the first horizontal direction in terms of layout. This symmetrical structure helps to maintain the overall balance and stability of the device. The code scanning mechanism 100 is composed of a third mounting frame 101 and a battery cell code scanner 102. The third mounting frame 101 is provided with mounting holes for adjusting the mounting position of the battery cell code scanner 102. The battery cell code scanner 102 can flexibly adjust its position on the third mounting frame 101 through these mounting holes, so that the battery cell code scanner 102 can adapt to the position and angle differences of different battery cell two-dimensional codes, improve the success rate and accuracy of code scanning, and ensure the effective collection of battery cell information.

[0067] In one possible embodiment, the third mounting frame 101 is mainly composed of two parts: a vertical plate 103 and a horizontal plate 104. Among them, the mounting hole includes a fourth waist hole 105 and a third arc hole 106. The fourth waist hole 105 is provided on the vertical plate 103, and the third arc hole 106 is provided on the horizontal plate 104. The vertical plate 103 is adjustably connected to the first mounting frame 305 through the fourth waist hole 105. In this way, the vertical position of the vertical plate 103 on the first mounting frame 305 can be flexibly adjusted through the fourth waist hole 105 to adapt to different height requirements. The horizontal plate 104 is located at the bottom of the vertical plate 103, and the connection between it and the vertical plate 103 is adjustable through the third arc hole 106. Through the third arc hole 106, the angle of the horizontal plate 104 relative to the vertical plate 103 can be adjusted, thereby bringing more adjustment possibilities to the battery cell scanner 102 installed at the bottom of the horizontal plate 104.

[0068] The battery cell code scanner 102 is firmly fixed to the bottom of the horizontal plate 104. With the help of the fourth waist hole 105 on the vertical plate 103 and the third arc hole 106 on the horizontal plate 104, the height and tilt angle of the battery cell code scanner 102 can be effectively adjusted respectively, so that the battery cell code scanner 102 can flexibly adjust its position and angle according to actual conditions, so as to better complete the scanning of the battery cell two-dimensional code, improve the accuracy and flexibility of code scanning, and thus ensure the efficiency and accuracy of the entire coding operation process.

[0069] See also Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, the coding device is further equipped with a dust suction mechanism 400, which is mainly composed of a dust suction pipe 401 and a dust suction box 402. One end of the dust suction box 402 is closely connected to the dust suction pipe 401, and the other end is provided with two opposite avoidance holes 403. The positions of the two avoidance holes 403 are carefully designed to ensure that the laser emitted by the laser coding mechanism 200 can pass smoothly, and at the same time, an efficient dust suction chamber is formed around the avoidance holes 403 inside the dust suction box 402. During the coding process, the dust suction pipe 401 generates a strong suction force through the dust suction chamber, and promptly removes the waste generated by the laser coding operation around the avoidance holes 403, thereby keeping the working environment clean and preventing the waste from causing adverse effects on the coding operation and equipment.

[0070] See also Figure 1As shown, in one embodiment, the coding device includes a lifting mechanism 500, which is located below the conveyor line and is mainly composed of a lifting cylinder 501 and a positioning pin 502. The driving end of the lifting cylinder 501 is tightly and firmly connected to the positioning pin 502, and the shape and size of the positioning pin 502 are carefully and accurately designed to perfectly match the corresponding positioning groove on the lithium battery module 600, thereby realizing accurate positioning of the lithium battery module 600.

[0071] In the actual working process, when the lifting mechanism 500 receives the command from the control system, the lifting cylinder 501 starts to work and drives the positioning pin 502 to move upward. The positioning pin 502 then lifts the lithium battery module 600 from the conveyor line smoothly, so that the lithium battery module 600 can be in a relatively stable state during the subsequent scanning and coding operations, effectively avoiding interference with the operation caused by the vibration or displacement of the conveyor line itself, and ensuring the accuracy and stability of the operation.

[0072] In a possible embodiment, the lifting mechanism 500 is additionally equipped with a support plate 503. At this time, the number of the lifting cylinders 501 is two, and they are respectively arranged on both sides below the support plate 503. The two lifting cylinders 501 work together to jointly drive the support plate 503 to achieve lifting operations, thereby ensuring the stability of the support plate 503 during the lifting process. The positioning pins 502 are arranged on the upper surface of the support plate 503. When the lithium battery module 600 is lifted, the positioning pins 502 will be accurately inserted into the positioning grooves corresponding to the lithium battery module 600. At the same time, the support plate 503 provides support for the lower surface of the lithium battery module 600. The two cooperate with each other to further ensure the stability of the lithium battery module 600 during the lifting process, and provide a more stable and reliable operating basis for subsequent scanning and coding operations.

[0073] In one embodiment, the lifting mechanism 500 further includes a blocking component 504 and a non-return component 505, which are respectively installed at both ends of the lifting station of the conveyor line and closely cooperate with the structure and operation mode of the conveyor line. The blocking component 504 is designed to prevent the lithium battery module 600 from moving forward in time when it is transported to the lifting station, and to confine it to a specific range of the lifting station. The non-return component 505 can prevent the lithium battery module 600 from reversing or shifting while waiting for the lifting, ensuring that the lithium battery module 600 is in the correct position waiting for the lifting operation, thereby improving the automation operation accuracy and stability of the entire device.

[0074] See also Figure 1As shown, in a possible embodiment, the blocking assembly 504 includes a base 5041, a blocking arm 5042, a torsion spring (not shown) and a driving member 5043. The shape of the blocking arm 5042 can be a strip or a plate, and its length and width are determined according to the size of the battery module and the width of the conveyor line. One end of the blocking arm 5042 is mounted on the base 5041 of the conveyor line through a rotating shaft so that it can be rotated up and down. The torsion spring is mounted on the rotating shaft, one end of which is connected to the blocking arm 5042 and the other end is connected to the base 5041. The function of the torsion spring is to provide a buffering effect when the blocking arm 5042 is impacted by the battery module, and at the same time, it can assist in resetting the blocking arm 5042 after it drops. The torque of the torsion spring can be adjusted according to the weight, speed and required buffering effect of the battery module. The driving member 5043 can be a cylinder or an electric push rod, which is mounted on the frame of the conveyor line to drive the lifting and lowering movement of the base 5041 and the blocking arm 5042, thereby realizing the rising blocking and descending and giving way actions of the blocking arm 5042.

[0075] In one possible implementation, the non-return assembly 505 may use a one-way pawl structure, including a pawl, a spring, and a mounting seat. The pawl is generally a metal component with a certain shape and strength, which can be mounted on the mounting seat through a rotating shaft. One end of the spring is connected to the pawl, and the other end is fixed to the mounting seat. When the lithium battery module 600 moves forward, the pawl will be pressed down by the lithium battery module 600 and compress the spring to allow it to pass smoothly; when the lithium battery module 600 tends to move backward, the pawl pops out under the restoring force of the spring to prevent the lithium battery module 600 from moving backward.
