Description

Technical Field

[0001] This invention relates to the field of laser welding technology, and more particularly to a battery cell welding device with an auxiliary feeding mechanism. Background Technology

[0002] The current battery cell welding process involves operators first loading multiple battery cells sequentially into a dedicated mold for fixation, then a transport mechanism moves the mold containing the battery cells to the welding station, where a welding unit performs centralized welding of the battery cells. This method not only improves operational safety but also increases the output per operation by arranging multiple battery cells within the mold. Furthermore, by setting up multiple sets of molds and employing alternating operation processes—for example, welding in mold A while loading battery cells into mold B—the welding and loading processes can be performed in parallel, thereby shortening the overall production cycle and improving processing efficiency.

[0003] However, in practical applications, the above-mentioned operation method requires operators to continuously follow the mold flow rhythm and accurately fill the battery cells. Long-term operation can easily lead to visual fatigue and operational negligence, resulting in battery cells not being processed for welding. Furthermore, if these battery cells are not detected in time and flow into subsequent processes, they cannot be processed normally. This not only directly affects the product yield, but may also require additional screening processes in the final stage for inspection and rework, increasing production costs and management complexity.

[0007] As an improvement to the above solution, the transport mechanism includes: a transport platform, fixedly connected to the front side of the base in the left-right direction, with side walls for limiting the position on the front and rear sides of its top, and a mounting frame fixedly connected to the transport platform across the entire length; at least three transport rollers, rotatably connected to the top surface of the transport platform, evenly distributed along the length of the transport platform, with a drive connection between adjacent sets of transport rollers; and a second motor, fixedly connected to the transport platform, which is drively connected to one of the transport rollers; the feed end of the transport platform is provided with a guide surface that tapers inward.

[0008] As an improvement to the above solution, each detection mechanism includes: a bracket, which is fixedly connected to the transport platform and is located on the loading side of the mounting frame in the corresponding loading mechanism; a detector, which is fixedly connected to the bracket and is used to identify the welding status of the battery cells on the mold passing below it. The detector is equipped with a second control module for processing the detection signal and is electrically connected to the first control module of the loading mechanism; and a limit plate, which is rotatably connected to the transport platform and is located on the discharge side of the mounting frame. It can be controlled to rotate by the first control module under drive and is used to stop the mold.

[0009] As an improvement to the above scheme, each detection mechanism also includes: a transmission gear, fixedly connected to the outside of the rotating shaft of the limiting plate; a guide bar, fixedly connected to the outer wall of the transport platform; a rack, slidably connected to the guide bar and meshing with the transmission gear; and an electrically controlled push rod, fixedly connected to the outer wall of the transport platform, with its end fixed to the rack, which can drive the rack to move linearly, and the electrically controlled push rod is electrically connected to the first control module.

[0013] The present invention has the following advantages: By coordinating and linking the transportation, inspection, loading and unloading mechanisms, the present invention achieves a high degree of automation and dual-station intelligent scheduling of the entire battery cell welding process. This not only effectively avoids the risk of missed welding caused by manual on-line operation, but also achieves continuous staggered cyclic operation through two independently controlled loading mechanisms and moving platforms, under the scheduling of the inspection mechanism, which significantly improves production efficiency and equipment operation stability.

[0014] The structure used in the transportation mechanism of this invention can cooperate with the detection mechanism to achieve flexible interception and diversion without stopping the machine, and without the need for precise start and stop control, so as to ensure the continuity and high cycle of the production process, while providing a precise material allocation basis for dual-station staggered operation.

[0015] In this invention, the unloading mechanism automatically separates the battery cells from the mold and exports them separately, providing material support for the continuous operation of the production line and further improving the level of automation and overall efficiency.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example: Battery cell welding equipment with an auxiliary feeding mechanism, see reference. Figures 1-3The system includes: a base 101 with a protective cover; two sets of parallel tracks 102 fixedly mounted on the base 101 in the front-to-back direction; two movable stages 103 slidably mounted on corresponding tracks 102 and capable of self-driving back-to-back movement along the tracks 102 for carrying and precisely positioning the mold 001 and the battery cells 002 it carries; a welding system 104 mounted at the rear of the base 101 for performing welding of the battery cells 002; and a positioning system 105 mounted at the front of the base 101 and signal-connected to the welding system 104. This system can move left and right to cover the working area of ​​the two movable stages 103, for detecting and calibrating the welding position of each battery cell 002 on the mold 001 and sending the positioning information to the welding system 104.

[0029] During operation, the mold 001 with battery cell 002 loaded is placed on the moving stage 103. The positioning system 105 moves directly above the moving stage 103 to detect and locate the welding points of the battery cell 002 and sends the data to the welding system 104. Subsequently, the moving stage 103, carrying the battery cell 002, moves backward to directly below the welding system 104, and the welding system 104 can then perform precise welding based on the received positioning information. During this process, another moving stage 103 can simultaneously unload the mold 001 with the welded battery cell 002 and load the next batch of battery cell 002 molds, thus realizing parallel operation of welding and loading / unloading processes in a staggered manner.

[0030] This equipment, by setting up dual moving tables 103 and a horizontally movable fixed-point system 105, realizes the cyclical alternation and parallel operation of fixed-point and welding processes, thereby significantly improving the continuous operation efficiency of this equipment; in addition, the linkage between the fixed-point system 105 and the welding system 104 can ensure the accuracy of each welding, and guarantee the product yield and production stability.

[0031] See Figure 1 , Figure 2 and Figure 6 The equipment also includes: a transport mechanism, located on the front side of the base 101, for automatically transporting the mold 001 loaded with the battery cell 002; The transport mechanism includes: a transport platform 301, fixedly installed on the front side of the base 101 in the left-right direction, with side walls for limiting the position on the front and rear sides of its top; at least three transport rollers 302, rotatably installed on the top surface of the transport platform 301, evenly distributed along the length of the transport platform 301, with adjacent sets of transport rollers 302 connected by a transmission belt assembly to achieve synchronous rotation; a second motor 303, fixedly installed on the transport platform 301, which is connected by a transmission belt assembly to provide rotation drive; an auxiliary roller 304, rotatably installed on the inner wall of the limiting walls on the front and rear sides of the transport platform 301, used to limit the front and rear position of the mold 001 while reducing friction; and a guide surface 305 that tapers inward at the feed end of the transport platform 301.

[0032] During operation, the second motor 303 drives all the transport rollers 302 to rotate synchronously, thereby smoothly transporting the mold 001; the guide surface 305 can automatically correct the placement position of the mold 001 to achieve rapid feeding; the auxiliary roller 304 provides lateral limiting and reduces frictional resistance during the transport of the mold 001, ensuring that the mold 001 can be smoothly and accurately transported to the designated transfer station, providing a reliable positional basis for subsequent positioning and welding processes.

[0033] This equipment uses a transport mechanism to achieve automatic feeding and precise conveying of mold 001. Through the cooperation of guide surface 305 and auxiliary roller 304, the reliance on manual placement accuracy is reduced, and the feeding efficiency and consistency are improved. In addition, its stable and smooth conveying function provides reliable position guarantee for subsequent positioning and welding processes, avoiding production rhythm disorder and missing welding risks that may be caused by delays from the source, and improving the automation and stability of the overall production.

[0034] See Figure 1 , Figure 2 , Figure 4 and Figure 5 The equipment also includes two sets of feeding mechanisms, located on the front side of the base 101 and corresponding to the front of the two moving tables 103 respectively, for automatically transferring and accurately placing the mold 001 loaded with battery cells 002 from the transport mechanism onto the corresponding moving table 103, and assisting in the staggered parallel operation of welding and feeding processes. Each loading mechanism includes: a mounting frame 201, horizontally fixedly mounted on the transport platform 301, with a first control module inside; a movable seat 202, slidably mounted on the mounting frame 201 in the front-to-back direction; a cylinder 203, vertically fixedly mounted inside the movable seat 202 and signal-connected to the first control module; a pick-and-place rack 204, fixedly mounted on the end of the telescopic rod of the cylinder 203, driven by the cylinder 203 for vertical displacement, and its structure is inverted U-shaped; suction cups 205, fixedly mounted on the inner walls of both sides of the pick-and-place rack 204, with no less than two suction cups 205 on each side; and an air source. 206 is fixedly installed on the pick-and-place rack 204 and connected to the first control module via signal; the connecting pipe 207 is fixedly installed and connected between the air source 206 and the suction cup 205, so that the suction cup 205 generates or releases negative pressure suction force uniformly; two lead screws 208 are rotatably installed on the top of the mounting frame 201 and threadedly engaged with the moving seat 202, and the two lead screws 208 are connected by transmission, specifically using a transmission belt assembly; the first motor 209 is fixedly installed on the mounting frame 201, and its output end is coaxially fixed with one of the lead screws 208 and electrically connected to the first control module.

[0035] During operation, when the transport mechanism delivers the mold 001 directly below the pick-and-place rack 204, the first control module controls the cylinder 203 to extend, causing the pick-and-place rack 204 to descend and cover the mold 001; then the air source 206 is activated, and the suction cup 205 adsorbs and fixes the mold 001; next, the cylinder 203 retracts, lifting the mold 001 away from the transport table 301; at the same time, the first motor 209 drives the lead screw 208, causing the pick-and-place rack 204 carrying the mold 001 to move backward until it reaches directly above the corresponding moving table 103; finally, the cylinder 203 extends again to lower the mold 001, the air source 206 is disconnected, and the suction cup 205 releases the mold 001, thus completing an automatic and precise loading operation.

[0036] This equipment uses two independent, automated feeding mechanisms to achieve fully automatic and precise transfer of mold 001 from the transport mechanism to the welding station. The transport mechanism replaces the original manual placement of mold 001, thereby reducing the labor intensity of operators. At the same time, the independent feeding of the two stations effectively supports continuous staggered operations, further improving the overall production efficiency and operational stability of the equipment.

[0037] See Figure 1 , Figure 2 , Figure 7 and Figure 8 The equipment also includes two sets of detection mechanisms, which are respectively set on the transport mechanism to correspond to the two sets of feeding mechanisms, and are used to identify the welding status of the battery cell 002 in order to control whether the mold 001 continues to move. Each detection mechanism includes: a bracket 401, which is fixedly mounted horizontally on the transport platform 301, located on the loading side of the mounting frame 201 in the corresponding loading mechanism; a detector 402, fixedly mounted on the bracket 401, used to identify the welding status of the battery cell 002 on the mold 001 passing below it; a limiting plate 403, rotatably mounted on the transport platform 301, located on the discharge side of the mounting frame 201; a transmission gear 404, fixedly mounted on the outside of the rotating shaft of the limiting plate 403; and a guide strip 405, fixedly mounted on the transport platform 301. On the outer wall of the conveyor 301; a rack 406 is slidably mounted on the guide bar 405 and meshes with the transmission gear 404; an electrically controlled push rod 407 is fixedly mounted on the outer wall of the conveyor 301, with its end fixed to the rack 406, which can drive the rack 406 to move linearly, thereby controlling the lifting and lowering of the limit plate 403 through the transmission gear 404; a second control module is provided in the detector 402 to process the detection signal and is electrically connected to the first control module of the feeding mechanism and the electrically controlled push rod 407.

[0038] When mold 001 is conveyed by transport roller 302 to below detector 402, detector 402 determines the welding status of battery cell 002: if battery cell 002 has been welded, the electric control push rod 407 does not move, the limit plate 403 remains in a tilted state, and mold 001 continues to move forward into the subsequent discharge process; if it detects that battery cell 002 has not been welded, the second control module immediately issues a command to extend the electric control push rod 407, drive the rack 406 to move, and flip the limit plate 403 to a vertical state perpendicular to the transport table 301, thereby accurately stopping mold 001. At this time, mold 001 is stopped directly below the corresponding feeding mechanism. The second control module issues a command to the first module to control the feeding mechanism to perform automatic gripping and transfer operations, placing it on the moving table 103 to await welding. During the above-mentioned stopping process, transport roller 302 continues to rotate, rotating relative to the bottom of the stationary mold 001, thereby achieving flexible stopping and sorting without stopping the machine.

[0039] This equipment achieves automatic detection and sorting functions through a detection mechanism, accurately identifying unsoldered battery cells (002) and automatically guiding them into the welding process, eliminating the possibility of unsoldered products flowing into the next process and significantly improving the product yield. Furthermore, it works seamlessly with the continuously operating transport and feeding mechanisms, ensuring the continuity of production rhythm while achieving fully automatic sorting, further enhancing the intelligence level and overall operational efficiency of this equipment.

[0040] See Figure 1 , Figure 2 , Figure 9 and Figure 10 The equipment also includes: a unloading mechanism, located at the discharge end of the transport mechanism, used to automatically separate the welded battery cell 002 from the bearing mold 001 and export them separately; The unloading mechanism includes: a separation platform 501, fixedly installed at the discharge end of the conveyor platform 301; a discharge platform 502, fixedly installed on the front side of the separation platform 501; a shovel 503, fixedly installed on the loading side edge of the discharge platform 502; a conveyor belt assembly 504, disposed on the surface of the discharge platform 502; at least three sets of pressing rollers 505, rotatably installed on the separation platform 501, equidistantly arranged along the length of the separation platform 501, with adjacent pressing rollers 505 connected by a transmission to achieve synchronous rotation, specifically using a transmission belt assembly; a transmission shaft 506, rotatably installed on the rear side of the discharge end of the conveyor platform 301, and connected by a transmission belt assembly to one of the pressing rollers 505; and a gear set 507, including two meshing gears, the two gears being fixedly installed on the transmission shaft 506 and the shaft end of the conveyor roller 302 near the transmission shaft 506, respectively.

[0041] During operation, the mold 001 carrying the welded battery cell 002 is conveyed to the separation table 501. The pressing roller 505 rotates synchronously but in the opposite direction with the transport roller 302 under the drive of the gear set 507, together clamping and stabilizing the conveyor of the mold 001. The pressing roller 505 is used to press down the mold 001 to prevent it from tilting. When the mold 001 moves to the point where the battery cell 002 on it contacts the shovel plate 503, the shovel plate 503 will gradually embed into the gap between the battery cell 002 and the mold 001, and smoothly shovel the battery cell 002 away from the mold 001. The separated battery cell 002 is then transferred to the conveyor belt set 504 of the discharge platform 502 and then directed to the subsequent process. The empty mold 001 continues to be conveyed along the original path to the external return line under the joint action of the pressing roller 505 and the transport roller 302, and is returned to the loading area for recycling.

[0042] This equipment achieves fully automatic separation and separate output of battery cell 002 and mold 001 through the cooperation of shovel plate 503 and linkage pressing roller 505. This process requires no manual intervention, which not only greatly improves unloading efficiency and avoids damage or confusion of battery cell 002 that may be caused by manual operation, but also provides closed-loop support for continuous production by returning the battery cell 002 to the mold 001. This process is seamlessly connected with the front-end detection, feeding and welding processes to jointly build a complete processing system with high efficiency, stability and high degree of automation, which significantly improves overall production efficiency and product consistency.

[0043] In summary, the overall workflow of this equipment constitutes an automated closed loop, from mold 001 loading, welding status recognition, alternating operation of dual workstations to finished product separation, as detailed below: The operator loads the battery cell 002 into the mold 001 and places the mold 001 at the feeding end of the transport mechanism. This is the only step in the process that requires manual intervention. Subsequently, the transport mechanism automatically transports the mold 001. The mold 001 first passes through the left detection mechanism. The detector 402 judges the welding status of the battery cell 002. After identifying that it is not welded, the second control module will activate the corresponding electric control push rod 407 to drive the limit plate 403 to stand up to intercept the mold 001. At the same time, it sends a command to the first control module of the left loading mechanism, so that the left loading mechanism starts to run and accurately transfers the mold 001 to the left moving table 103, ready for welding operation. At this time, the left-side loading mechanism does not immediately return to its original position. Instead, it waits for the mold 001 to complete welding before transporting the mold 001 along with the welded battery cell 002 back to the transport line. Therefore, during this period, if the next mold 001 arrives at the left-side inspection station, the left-side detector 402, through signal linkage between the first and second control modules, will detect that the left-side loading mechanism is in operation and will not trigger an interception. The mold 001 will then continue to move and be transported to the right-side station. The right-side inspection mechanism, in cooperation with the loading mechanism, will transfer it to the right-side moving table 103 for welding, thus achieving alternating operation between the two stations. When the welding at the left-side station is completed and the loading mechanism returns the mold 001 to the transport mechanism, the right-side loading mechanism is in operation. Therefore, the welded mold 001 will directly pass through the right-side loading station and ultimately be transported to the unloading mechanism on the discharge side. Finally, in the unloading mechanism, the battery cell 002 and the mold 001 are automatically separated: the battery cell 002 is discharged through the discharge platform 502 and enters the next process, while the empty mold 001 is guided to the return path and returned to the loading area for manual reloading, so as to achieve recycling.
