Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to a feeding system and a battery welding system. Background Technology

[0002] In the battery manufacturing process, many steps involve battery transfer and loading operations. For example, in the battery welding process, batteries are usually placed horizontally during transport to prevent them from falling. However, during welding, the batteries need to be rotated at a certain angle to facilitate welding at the ends of the batteries.

[0003] In related technologies, batteries are typically rotated manually, or guide rails are installed between the loading and welding positions, allowing the batteries to rotate naturally. However, regardless of manual operation or the use of guide rails, the angle of the rotated battery often deviates, resulting in low overall operational efficiency and directly impacting overall production efficiency. Therefore, improving the accuracy and efficiency of battery rotation angle, and thus optimizing the overall loading efficiency of the loading system, has become an urgent technical problem to be solved. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a feeding system that can effectively improve the accuracy of the placement orientation of the adjusted battery, thereby facilitating subsequent battery processing and optimizing the overall feeding efficiency of the feeding system.

[0076] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0077] The following is for reference. Figures 1-25 A feeding system 100 according to an embodiment of the present invention is described.

[0078] Reference Figures 1-5 According to a first aspect embodiment of the present invention, a feeding system 100 includes a conveying unit 1, a rotating unit 2, a first transfer unit 3, and a second transfer unit 4. The conveying unit 1 is used to convey a battery 7 along a first direction (e.g., the e1 direction in the figures). The conveying unit 1 has a plurality of feeding positions 111 spaced apart along the first direction. The feeding positions 111 are used to place the battery 7 and to place the battery 7 along the first placement direction. The rotating unit 2 includes a rotating drive mechanism 21 and a rotating member 22. The rotating member 22 is located in the conveying unit 1. The discharge end 121 of the conveying unit 1 has a placement position 221 for placing the battery 7. The rotary drive mechanism 21 is connected to the rotary member 22 and is used to drive the rotary member 22 to rotate so as to adjust the placement direction of the battery 7 to a second placement direction. The second placement direction is different from the first placement direction. The first transfer unit 3 is located at the discharge end 121 of the conveying unit 1 and is used to transfer the battery 7 located at the discharge end 121 to the placement position 221 of the rotary member 22. The second transfer unit 4 is used to transfer the battery 7 located in the second placement direction on the rotary unit 2 to the processing station 634.

[0079] The conveying unit 1 is equipped with multiple loading positions 111 arranged at intervals along a first direction, which can simultaneously convey multiple batteries 7, realizing batch conveying of batteries 7 and giving the conveying unit 1 high conveying efficiency. The loading positions 111 are used to place the batteries 7 along the first placement direction, for example, so that the side of the battery 7 contacts the conveying unit 1. Since the side of the battery 7 is mostly flat, placing the battery 7 along the first placement direction can make the battery 7 more stably located at the loading position 111, reducing friction and wear caused by the rolling of the battery 7 during the conveying process.

[0080] By providing a first transfer unit 3 for transferring the battery 7 to the rotating component 22, the battery 7 located at the discharge end 121 can be transferred to the rotating unit 2 in a timely manner, avoiding the accumulation of batteries 7 between the conveying unit 1 and the rotating unit 2, so that the rotating unit 2 can adjust the placement direction of the battery 7. The rotating unit 2 includes a rotation drive mechanism 21 and a rotating component 22. The rotation drive mechanism 21 can drive the rotating component 22 to rotate, thereby adjusting the placement direction of the battery 7 placed at the placement position 221 of the rotating component 22, so as to facilitate subsequent processing. This can improve the accuracy of the adjusted placement direction of the battery 7 and help optimize the overall feeding efficiency of the feeding system 100.

[0081] During the process of the first transfer unit 3 transferring the battery 7 from the discharge end 121 of the conveying unit 1 to the rotating component 22, the battery 7 is always in the first placement direction.

[0082] For example, compared to using manual operation or guide rails to make the battery 7 rotate naturally, the rotation drive mechanism 21 drives the rotating component 22 to rotate the battery 7. The rotation drive mechanism 21 can provide a higher precision angle control function. With the rigid structure of the rotating component 22, the placement direction of the battery 7 can be adjusted to the second placement direction more accurately. This can achieve precise control of the rotation angle of the battery 7, ensuring that the battery 7 switches from the first placement direction to the second placement direction. This avoids the random errors of manual operation or the uncontrollable deviations of the guide rails, which in turn helps to improve the angular accuracy of the battery 7 in the workstation 634, thereby reducing the increase in manufacturing errors caused by the positioning deviation of the battery 7 in subsequent processing.

[0083] For example, the rotating part 22 can be cylindrical in shape.

[0084] For example, the rotating component 22 drives the battery 7 to rotate 90°, so that the battery 7 is adjusted from the first placement direction to the second placement direction.

[0085] For example, battery 7 can be a cylindrical battery. When battery 7 is in the first placement direction, battery 7 is placed flat and the central axis of battery 7 extends in the horizontal direction. For example, the central axis of battery 7 can extend in the second direction. When battery 7 is in the second placement direction, battery 7 is placed vertically and the central axis of battery 7 extends in the vertical direction.

[0086] By providing a second transfer unit 4 for transferring the battery 7 to the processing station 634, the battery 7 located in the second placement direction can be transferred to the processing station 634 in a timely manner, avoiding the accumulation of the battery 7 between the rotating unit 2 and the processing station 634, so that the battery 7 can be processed in the processing station 634 in a timely manner.

[0087] During the process of the second transfer unit 4 transferring the battery 7 located in the second placement direction on the rotating unit 2 to the processing station 634, the battery 7 is always in the second placement direction, and after the battery 7 is placed in the processing station 634, the battery 7 is also in the second placement direction.

[0088] Through the coordinated operation of conveying unit 1, first transfer unit 3, conveying unit 1 and second transfer unit 4, the orderly flow of battery 7 from loading position 111 to processing position 634 can be realized, avoiding confusion and conflict of battery 7 during the flow process, thereby realizing the continuous and cyclical operation of loading system 100.

[0089] For example, the loading process of battery 7 can be as follows: when battery 7 is at loading position 111, conveying unit 1 is used to convey battery 7 to rotating unit 2. When battery 7 moves to the discharge end 121 of conveying unit 1, first transfer unit 3 can transfer battery 7 to rotating unit 2. By driving rotating component 22 to rotate through rotating drive mechanism 21, the placement direction of battery 7 can be adjusted from the first placement direction to the second placement direction. After the placement direction of battery 7 is adjusted to the second placement direction, second transfer unit 4 transfers battery 7 to processing station 634 to facilitate subsequent processing and manufacturing.

[0090] In the description of this invention, "a plurality of" means two or more.

[0091] According to an embodiment of the present invention, the feeding system 100, by providing a first transfer unit 3 for transferring the battery 7 located at the discharge end 121 of the conveying unit 1 to the rotating member 22, can promptly transfer the battery 7 located at the discharge end 121 to the rotating unit 2, so that the rotating unit 2 can adjust the placement direction of the battery 7; and, since the rotating unit 2 includes a rotation drive mechanism 21 and a rotating member 22, the rotation drive mechanism 21 can drive the rotating member 22 to rotate, so as to adjust the placement direction of the battery 7 placed at the placement position 221 of the rotating member 22. Compared with the manual rotation and slide rail guided rotation in the related art, the rotation drive mechanism 21 can provide a higher precision angle control function, and can adjust the placement direction of the battery 7 to a second placement direction more accurately. This can effectively improve the accuracy of the placement direction of the adjusted battery 7, so as to facilitate the subsequent processing of the battery 7, and the operation efficiency is higher, which is conducive to optimizing the overall feeding efficiency of the feeding system 100.

[0092] Reference Figures 16-18According to some embodiments of the present invention, the rotary drive mechanism 21 includes a rotary drive motor 211 and a rotation angle detection device 212. The output shaft of the rotary drive motor 211 is connected to the rotating component 22, and the rotation angle detection device 212 is disposed on the output shaft of the rotary drive motor 211 for detecting the rotation angle of the rotating component 22. By providing the rotation angle detection device 212 for detecting the rotation angle of the rotating component 22, the actual rotation angle of the rotating component 22 can be compared with the preset rotation angle. If an angle deviation is detected between the actual rotation angle of the rotating component 22 and the preset rotation angle, the rotation of the output shaft of the rotary drive motor 211 can be adjusted in time to improve the accuracy of the rotation angle of the rotating component 22 and effectively reduce the rotation angle deviation of the rotating component 22, thereby improving the accuracy of the angle after the battery 7 is rotated.

[0093] Reference Figures 16-18 According to some embodiments of the present invention, the rotation angle detection device 212 is a photoelectric encoder. The photoelectric encoder collects the rotation angle information of the rotating part 22 in real time through optical principles, and can convert the mechanical rotation amount into a pulse electrical signal, so as to measure the rotation angle of the rotating part 22 in a relatively timely and accurate manner.

[0094] Reference Figures 16-18 According to some embodiments of the present invention, the rotary drive motor 211 is a servo motor. The servo motor can control the speed and torque more precisely, thereby achieving precise control of the rotation angle of the rotating part 22, effectively reducing the rotation angle deviation of the rotating part 22, which is beneficial to improving the accuracy of the angle after the battery 7 rotates.

[0095] Reference Figure 6 , Figure 7 , Figure 19 and Figure 20 According to some embodiments of the present invention, the rotating unit 2 is located on one side of the conveying unit 1 along a second direction (e.g., referring to direction e2 in the figures), the second direction intersecting the first direction. The rotation axis of the rotating member 22 extends along the first direction, and the placement position 221 is located on the outer peripheral wall of the rotating member 22. The first transfer unit 3 is used to transfer the battery 7 at the discharge end 121 to the placement position 221 along the second direction. By positioning the rotating unit 2 on one side of the conveying unit 1 along the second direction, rather than occupying the space in the first direction, the space in the second direction is fully utilized, effectively shortening the overall length of the feeding system 100 in the first direction and reducing the space constraints of the subsequent production line layout. Furthermore, by positioning the placement position 221 on the outer peripheral wall of the rotating member 22, the distance between the placement position 221 and the conveying unit 1 can be closer, so that the first transfer unit 3 can move the battery 7 located at the discharge end 121 of the conveying unit 1 to the placement position 221.

[0096] Reference Figure 6 , Figure 7 , Figure 19 and Figure 20 According to some embodiments of the present invention, the first transfer unit 3 includes a magnetic suction member 31, which uses magnetic attraction to transfer the battery 7 from the discharge end 121 to the placement position 221. When the magnetic suction member 31 is close to the battery 7, it can directly attract the battery 7 through magnetic attraction. By moving the magnetic suction member 31, the battery 7 can be transferred to the placement position 221 along the second direction without clamping or squeezing the battery 7, which can effectively reduce friction and wear on the battery 7 casing caused by clamping.

[0097] Furthermore, the magnetic suction component 31 transfers the battery 7 to the placement position 221 of the rotating component 22 by magnetic attraction, which allows the battery 7 to move in a straight line without changing the placement direction of the battery 7 during the transfer process. The battery 7 is always in the first placement direction during the transfer process. In this way, the battery 7 can be accurately adjusted to the second placement direction by rotating the rotating component 22 to drive the battery 7 to rotate.

[0098] Reference Figure 6 , Figure 7 , Figure 19 and Figure 20 According to some embodiments of the present invention, a receiving cavity 222 is formed inside the rotating member 22, the magnetic suction member 31 is located inside the receiving cavity 222, and the placement position 221 is formed as a hole structure and penetrates the inner peripheral wall of the receiving cavity 222.

[0099] For example, battery 7 is a cylindrical battery, and placement position 221 is formed as a circular hole.

[0100] By forming a receiving cavity 222 in the rotating member 22 and placing the magnetic suction member 31 therein, the space within the rotating member 22 can be fully utilized, making the overall structure of the magnetic suction member 31 and the rotating member 22 compact and reducing the space occupied by the magnetic suction member 31 and the rotating member 22 as a whole. Furthermore, by forming the placement position 221 as a hole structure that penetrates the inner peripheral wall of the receiving cavity 222, an unobstructed conduction path can be provided for the magnetic attraction force of the magnetic suction member 31, eliminating the obstruction of magnetic attraction force conduction and reducing the loss in the magnetic attraction force conduction process. This allows the magnetic attraction force to act directly on the battery 7, so as to attract the battery 7 located at the discharge end 121 to the placement position 221, avoiding the attenuation of magnetic attraction force due to wall obstruction.

[0101] In addition, by incorporating the magnetic suction component 31 into the receiving cavity 222 of the rotating component 22 and linking it with the rotating component 22, the battery 7 can seamlessly connect the two actions of transferring from the loading position 111 to the placement position 221 and the rotation operation of the battery 7, which greatly reduces the waiting interval between the two actions, thereby reducing timing errors and further improving the operating cycle of the loading system 100.

[0102] Reference Figure 6 , Figure 7 , Figure 19 and Figure 20 According to some embodiments of the present invention, the placement position 221 includes a first hole segment 2211 and a second hole segment 2212. The second hole segment 2212 is located on the side of the first hole segment 2211 near the receiving cavity 222. A stepped surface 2213 is formed between the first hole segment 2211 and the second hole segment 2212. The first hole segment 2211 is used to place the battery 7. The stepped surface 2213 formed between the first hole segment 2211 and the second hole segment 2212 can limit the battery 7. When the magnetic suction member 31 moves the battery 7 to the first hole segment 2211 by magnetic attraction, the stepped surface 2213 can limit the magnetic attraction from continuing to pull the battery 7 toward the receiving cavity 222, so that the battery 7 is stably located in the first hole segment 2211.

[0103] Reference Figures 16-20 According to some embodiments of the present invention, the first transfer unit 3 includes a first transfer drive mechanism 32, which is connected to the magnetic suction member 31 and is used to drive the magnetic suction member 31 to move along a second direction. By providing the first transfer drive mechanism 32, the magnetic suction member 31 can be driven to move along the second direction, which can make the distance between the magnetic suction member 31 and the battery 7 located at the discharge end 121 closer, so that its magnetic attraction force is kept within the range of efficient action, so that the magnetic attraction force of the magnetic suction member 31 can act better on the battery 7, so that the battery 7 can be transferred more smoothly from the loading position 111 to the placement position 221. It can also make the magnetic suction member 31 move to the end of the battery 7, so that the magnetic attraction force of the magnetic suction member 31 acts directly on the surface of the battery 7. By moving the magnetic suction member 31 along the second direction, the process of the magnetic suction member 31 driving the battery 7 from the loading position 111 to the placement position 221 is realized.

[0104] Reference Figures 16-20 According to some embodiments of the present invention, the magnetic suction member 31 is formed as a rod extending along a second direction, and the first transfer drive mechanism 32 is used to drive the magnetic suction member 31 to move along the second direction between a first position and a second position. In the first position, the magnetic suction member 31 passes through the placement position 221, and the rotating unit 2 and the conveying unit 1 are both in a stopped state. In the second position, the magnetic suction member 31 is separated from the placement position 221 and the magnetic suction member 31 is housed in the receiving cavity 222.

[0105] When the magnetic suction member 31 is in the first position, it passes through the placement position 221, and both the rotating unit 2 and the conveying unit 1 are in a stopped state. This allows the magnetic suction member 31 to move smoothly from the receiving cavity 222 through the placement position 221 to the loading position 111 to attract the battery 7, thus avoiding interference between the rotating member 22 and the magnetic suction member 31. Furthermore, when the magnetic suction member 31 is in the second position, it separates from the placement position 221 and is stored in the receiving cavity 222. This allows the rotating member 22 to smoothly drive the battery 7 to rotate, thereby adjusting the battery 7 from the first placement direction to the second placement direction, effectively avoiding interference between the rotation of the rotating member 22 and the magnetic suction member 31.

[0106] In some embodiments, the placement position 221 includes a first hole segment 2211 and a second hole segment 2212. The second hole segment 2212 is located on the side of the first hole segment 2211 near the receiving cavity 222. A stepped surface 2213 is formed between the first hole segment 2211 and the second hole segment 2212. The first hole segment 2211 is used to place the battery 7. When the magnetic suction member 31 moves from the loading position 111 toward the receiving cavity 222, the stepped surface 2213 formed between the first hole segment 2211 and the second hole segment 2212 can make the battery 7 more stably located in the first hole segment 2211. When the magnetic suction member 31 continues to move toward the receiving cavity 222, the stepped surface 2213 can restrict the movement of the battery 7, so that the battery 7 is more stably located in the first hole segment 2211, and the battery 7 is prevented from continuing to move toward the receiving cavity 222 under the action of the magnetic suction force of the magnetic suction member 31. This can prevent the battery 7 from interfering with the magnetic suction member 31 when rotating.

[0107] For example, the process of the magnetic suction component 31 moving the battery 7 from the discharge end 121 to the placement position 221 by magnetic attraction can be as follows: when the magnetic suction component 31 moves the battery 7 to the placement position 221, the step surface 2213 can serve as the physical trigger point for the battery 7 to be placed in the placement position 221. That is, the battery 7 abutting against the step surface 2213 indicates that the battery 7 is stably placed in the placement position 221. When the magnetic suction component 31 continues to move toward the receiving cavity 222, the battery 7 is limited by the step surface 2213 and can detach from the magnetic suction component 31 so as to rotate with the rotating component 22.

[0108] Reference Figures 16-20According to some embodiments of the present invention, the first transfer drive mechanism 32 is located outside the rotating member 22, and the first transfer unit 3 includes a connecting bracket 33 connected between the first transfer drive mechanism 32 and the magnetic suction member 31. An opening 2221 is formed on one side of the receiving cavity 222 along the first direction, and the opening 2221 is used to avoid the connecting bracket 33. By connecting the first transfer drive mechanism 32 and the magnetic suction member 31 with the connecting bracket 33, power transmission between the first transfer drive mechanism 32 and the magnetic suction member 31 can be realized. Furthermore, by forming an opening 2221 on one side of the receiving cavity 222 along the first direction to avoid the connecting bracket 33, and by having the rotation axis of the rotating member 22 extend along the first direction, interference between the rotating member 22 and the connecting bracket 33 during rotation can be avoided.

[0109] The first transfer drive mechanism 32 is connected by the connecting bracket 33, and the receiving cavity 222 has an open opening 2221 on one side along the first direction to avoid the connecting bracket 33. While the first transfer drive mechanism 32 drives the magnetic suction member 31 to move along the second direction via the connecting bracket 33, the rotation of the rotating member 22 can be prevented from interfering with the first transfer unit 3.

[0110] Reference Figures 16-20 According to some embodiments of the present invention, the rotating member 22 is provided with multiple sets of placement positions 220, which are arranged at intervals along the circumference of the rotating member 22. Each set of placement positions 220 includes one placement position 221 or multiple placement positions 221 arranged along the axial direction of the rotating member 22. By arranging multiple sets of placement positions 220 at intervals along the circumference of the rotating member 22, the placement direction of the battery 7 in one set of placement positions 220 can be adjusted every time the rotating member 22 rotates by a preset angle. The preset angle is the included angle between two adjacent sets of placement positions 220.

[0111] Taking each placement position group 220 as an example, which includes multiple placement positions 221 arranged along the axis of the rotating member 22, the number of batteries 7 transferred by the first transfer unit 3 each time is the same as the number of placement positions 221 in the same placement position group 220. This allows the rotating member 22 to adjust the rotation angle of multiple batteries 7 in the same placement position group 220 at the same time within a unit of time. This enables batch adjustment of the angle of the batteries 7, improves the rotation efficiency of the rotating member 22 on the angle of the batteries 7, and thus helps to improve the overall loading efficiency of the loading system 100.

[0112] According to some embodiments of the present invention, there are four groups of placement positions 220, which are evenly spaced along the circumference of the rotating member 22, such that the angle between two adjacent groups of placement positions 220 is 90°. This allows the battery 7 to be rotated 90° each time the rotating member 22 rotates. For example, the battery 7 can be a cylindrical battery. When the battery 7 is in the first placement direction, the battery 7 is placed flat, and the central axis of the battery 7 extends horizontally, for example, the central axis of the battery 7 can extend in a second direction. When the battery 7 is in the second placement direction, the battery 7 is placed vertically, and the central axis of the battery 7 extends vertically. By rotating the rotating member 22 once, that is, moving from the previous group of placement positions 220 to the next adjacent group of placement positions 220, the battery 7 can be rotated 90°, thereby realizing the process of rotating the battery 7 from the first placement direction to the second placement direction.

[0113] For example, during the feeding process, when the magnetic suction component 31 of the first transfer unit 3 completes the adsorption of the previous group of batteries 7 and adjusts the group of batteries 7 from the first placement direction to the second placement direction by rotating the rotating component 22, the adjacent next group of empty placement positions 220 on the rotating component 22 will synchronously rotate to a position aligned with the feeding position 111 of the discharge end 121 along the second direction. In this way, when the magnetic suction component 31 adsorbs the next group of batteries 7 located at the discharge end 121, there is no need to adjust the angle of the rotating component 22. At this time, the magnetic suction component 31 can directly adsorb the next group of batteries 7, reducing the waiting gap between the transfer operation of the first transfer unit 3 on the batteries 7 and the rotation operation of the rotating component 22 on the batteries 7, which is beneficial to improving the feeding efficiency of the feeding system 100.

[0114] When the battery 7 is in the first placement direction, the side of the battery 7 is in contact with the conveying unit 1. By rotating the battery 7 by 90°, the battery 7 is placed in the second placement direction and the end of the battery 7 can be facing upward, so as to facilitate subsequent processing of the end of the battery 7.

[0115] Reference Figures 11-15 According to some embodiments of the present invention, the conveying unit 1 includes a conveying frame 12 and a conveying mechanism. The conveying mechanism is disposed on the conveying frame 12 and includes a conveyor belt 11 with a loading position 111 formed on the conveyor belt 11. The conveying frame 12 can serve as a carrier for the conveying mechanism, providing support and fixation. The loading position 111 is formed on the conveyor belt 11. The surface of the conveyor belt 11 has a certain degree of flexibility, which can reduce scratches on the surface of the battery 7. Furthermore, the conveyor belt 11 has a relatively high coefficient of friction. By utilizing the frictional force of the conveyor belt 11 on the battery 7, the battery 7 can be stably supported on the conveyor belt 11.

[0116] Reference Figures 11-15According to some embodiments of the present invention, the loading position 111 is a receiving groove formed on the conveyor belt 11, and the loading position 111 extends along the second direction. By forming a receiving groove on the conveyor belt 11, at least a portion of the battery 7 can be received in the receiving groove, and the receiving groove can play a certain limiting role for the battery 7, so that the battery 7 is more stably located on the conveyor belt 11, effectively reducing the rolling of the battery 7 on the conveyor belt 11.

[0117] Reference Figures 11-15 According to some embodiments of the present invention, the battery 7 is a cylindrical battery, and the cross-section of the loading position 111 is arc-shaped, which can make the loading position 111 fit as closely as possible to the outer surface of the battery 7, so as to effectively enhance the limiting effect of the loading position 111 on the battery 7, so that the battery 7 is stably located at the loading position 111 during the conveying process, and reduce the rolling of the battery 7 on the conveyor belt 11.

[0118] Reference Figure 8 , Figure 11 and Figure 20 According to some embodiments of the present invention, a transfer platform 5 is provided between the discharge end 121 of the conveying frame 12 and the outer peripheral wall of the rotating member 22. A guide groove 51 is formed on the upper surface of the transfer platform 5. The guide groove 51 is located on one side of the loading position 111 of the discharge end 121 along the second direction and extends along the second direction. By providing a transfer platform 5 between the discharge end 121 of the conveying frame 12 and the outer peripheral wall of the rotating member 22, the gap between the conveying unit 1 and the rotating unit 2 can be better filled, effectively preventing the possibility of the battery 7 falling out of the gap between the conveying unit 1 and the rotating unit 2 when it moves from the conveying unit 1 to the rotating unit 2.

[0119] Furthermore, a guide groove 51 is formed on the upper surface of the transfer platform 5. When the battery 7 moves from the conveying unit 1 to the rotating unit 2, the guide groove 51 can guide the battery 7 to move more smoothly from the loading position 111 to the placement position 221. For example, the guide groove 51 can be at least partially opposite to the placement position 221. In this way, when the battery 7 moves, the guide groove 51 can guide the battery 7 to accurately match the height of the conveyor belt 11 and the placement position 221 of the rotating part 22, so that the battery 7 can maintain the second direction of movement during the transfer process, reducing the position adjustment of the battery 7 in the vertical direction.

[0120] For example, the battery 7 is a cylindrical battery, and the cross-section of the guide groove 51 can be arc-shaped, so that the bottom wall of the guide groove 51 fits as closely as possible to the outer surface of the battery 7, which can play a certain limiting role in the radial direction of the battery 7 to prevent the battery 7 from rolling off the transfer platform 5.

[0121] Furthermore, the center of the arc of the guide groove 51 can be aligned with the center of the placement position 221 along the second direction, so that the battery 7 can be accurately placed into the placement position 221 under the guidance of the guide groove 51.

[0122] Reference Figures 9-11 According to some embodiments of the present invention, the transfer platform 5 is connected to the conveyor frame 12 and the transfer platform 5 and the conveyor frame 12 are integrally formed. This can improve the overall structural strength of the transfer platform 5 and the conveyor frame 12, and can eliminate the assembly process between the transfer platform 5 and the conveyor frame 12, thereby improving the overall assembly efficiency of the feeding system 100.

[0123] Reference Figures 11-15 According to some embodiments of the present invention, the conveyor frame 12 is provided with a first limiting baffle 122 and a second limiting baffle 123. The first limiting baffle 122 and the second limiting baffle 123 are arranged at intervals along the second direction and both extend along the first direction. The conveyor belt 11 is located between the first limiting baffle 122 and the second limiting baffle 123. In the second direction, the second limiting baffle 123 is located on the side of the conveyor frame 12 closer to the rotating unit 2. The portion of the second limiting baffle 123 located at the discharge end 121 forms a discharge hole 1231. The discharge hole 1231 faces the outer peripheral wall of the rotating member 22 and is used for the discharge of the battery 7 located at the discharge end 121. The conveyor belt 11 is located between the first limiting baffle 122 and the second limiting baffle 123. The first limiting baffle 122 and the second limiting baffle 123 can limit the battery 7 on the conveyor belt 11, so that the battery 7 is stably located on the conveyor belt 11 during the conveying process, and the possibility of the battery 7 falling off the conveyor belt 11 is avoided.

[0124] Furthermore, a discharge hole 1231 is formed in the part of the second limiting baffle 123 located at the discharge end 121, which facilitates the movement of the battery 7 to the rotating unit 2 through the discharge hole 1231.

[0125] For example, the loading process of battery 7 can be as follows: when battery 7 is at loading position 111, conveyor belt 11 is used to transport battery 7 to discharge end 121. When battery 7 moves to discharge end 121, first transfer unit 3 can transfer battery 7 from discharge hole 1231 to rotation unit 2. By driving rotating component 22 to rotate through rotation drive mechanism 21, the placement direction of battery 7 can be adjusted from first placement direction to second placement direction. After the placement direction of battery 7 is adjusted to the second placement direction, second transfer unit 4 transfers battery 7 to processing station 634 to facilitate subsequent processing and manufacturing.

[0126] In some embodiments, the rotating member 22 is provided with multiple sets of placement positions 220, which are arranged at intervals along the circumference of the rotating member 22. Each set of placement positions 220 includes one placement position 221 or multiple placement positions 221 arranged along the axial direction of the rotating member 22. The portion of the second limiting baffle 123 located at the discharge end 121 forms one discharge hole or multiple discharge holes 1231 arranged along the first direction. The number of discharge holes 1231 is the same as the number of placement positions 221 and corresponds one-to-one.

[0127] Taking each placement position group 220 as an example, which includes multiple placement positions 221 arranged along the axial direction of the rotating member 22, the portion of the second limiting baffle 123 located at the discharge end 121 has multiple discharge holes 1231. When the magnetic suction member 31 of the first transfer unit 3 attracts and transfers the battery 7 located at the discharge end 121 through magnetic attraction, the magnetic suction member 31 can simultaneously attract and transfer multiple batteries 7 through multiple discharge holes 1231 within a unit time and move them into the same placement position group 220. This can improve the transfer efficiency of the first transfer unit 3 for the battery 7, thereby improving the overall feeding efficiency of the feeding system 100.

[0128] Reference Figures 11-15 According to some embodiments of the present invention, the discharge end 121 is provided with a feeding position sensor. The feeding position sensor is used to detect whether a battery 7 is placed at the feeding position 111 located at the discharge end 121. The feeding position sensor is electrically connected to both the conveying unit 1 and the first transfer unit 3. When a battery 7 is placed at the feeding position 111 of the discharge end 121, the conveying unit 1 is in a stopped state and the first transfer unit 3 is in a working state.

[0129] A feeding position sensor is provided at the discharge end 121 to detect whether a battery 7 is placed at the feeding position 111 located at the discharge end 121. The sensor can detect in real time whether there is a battery 7 at the feeding position 111 located at the discharge end 121. The feeding position sensor is electrically connected to the conveying unit 1 and the first transfer unit 3, which can realize the signal transmission between the feeding position sensor and the conveying unit 1 and the first transfer unit 3. This allows the conveying unit 1 and the first transfer unit 3 to transfer the battery 7 located at the feeding position 111 of the discharge end 121 in a timely manner based on the information measured by the feeding position sensor, so as to avoid the continued operation of the conveying unit 1 and the subsequent accumulation of batteries 7.

[0130] For example, the loading position sensor is a fiber optic sensor.

[0131] For example, when the feeding position sensor detects that a battery 7 is placed at the feeding position 111 at the discharge end 121, the control conveying unit 1 is in a stopped state and simultaneously sends a working signal to the first transfer unit 3, so that the first transfer unit 3 promptly transfers the battery 7 at the feeding position 111 at the discharge end 121 to the rotating unit 2. The automatic connection of the battery 7 being in place, the conveying unit 1 stopping, and the first transfer unit 3 starting can be completed without manual intervention, which can reduce the error and waiting time of manual operation and effectively improve the operating cycle of the feeding system 100.

[0132] Reference Figures 6-8 According to some embodiments of the present invention, the second transfer unit 4 includes a second transfer drive mechanism 42 and a clamping mechanism 41. The second transfer drive mechanism 42 is connected to the clamping mechanism 41 to drive the clamping mechanism 41 to move between the rotating member 22 and the workstation 634. The clamping mechanism 41 includes a clamping drive mechanism and a gripper 411. The clamping drive mechanism is connected to the gripper 411 to drive the gripper 411 to clamp or release the battery 7. The clamping drive mechanism can drive the gripper 411 to clamp or release, thereby realizing the switching between the clamping state and the releasing state of the gripper 411 mechanism to clamp or release the battery 7.

[0133] Reference Figures 6-8 According to some embodiments of the present invention, the gripper 411 includes a gripper body and a buffer layer, wherein the buffer layer is provided on the inner side of the gripper body. When the gripper body clamps the battery 7, the buffer layer is located between the battery 7 and the gripper body. The buffer layer can transform the rigid contact between the gripper body and the battery 7 into a flexible contact through its own elastic deformation, thereby avoiding the possibility of the battery 7 casing being damaged, indented, or even broken by the gripper body.

[0134] Reference Figure 8 According to some embodiments of the present invention, the buffer layer is a polyurethane layer. Since polyurethane has good elasticity and wear resistance, by using a polyurethane layer as the buffer layer, the buffer layer can have better elasticity, so as to better absorb the clamping force of the gripper body and avoid the possibility of the battery 7 casing being pinched, indented or even broken by the gripper body.

[0135] Reference Figure 8 According to some embodiments of the present invention, the Shore hardness of the buffer layer ranges from 50A to 65A. For example, the Shore hardness of the buffer layer can be 50A, 53A, 58A, 60A, 65A, etc.

[0136] With a Shore hardness range of 50A to 65A, the buffer layer can effectively absorb the clamping force of the gripper body, thereby reducing wear on the battery 7. This avoids the buffer layer being unable to deform properly to absorb the clamping force due to excessively hard material. It also ensures that the buffer layer has a certain degree of hardness to prevent the buffer layer from being easily worn or torn due to excessively soft material.

[0137] Reference Figure 8 According to some embodiments of the present invention, the opening diameter of the gripper 411 is in the range of 18mm to 26mm. For example, the opening diameter of the gripper 411 can be 18mm, 19mm, 20mm, 23mm, 26mm, etc.

[0138] With the opening diameter of the gripper 411 ranging from 18mm to 26mm, the gripper 411 can grip a variety of battery sizes 7, allowing for more flexible gripping of different battery sizes 7 without the need for frequent adjustment or replacement of the gripper 411 for different battery sizes 7. For example, it can reduce the downtime of the feeding system 100 caused by replacing the gripper 411, enabling the feeding system 100 to adapt to the feeding needs of multiple battery sizes 7.

[0139] For example, the clamping drive mechanism includes a clamping motor, which drives the gripper 411 to clamp or release the battery 7. By driving the gripper 411 with the clamping motor, the opening diameter of the gripper 411 can be controlled more precisely to better adapt to batteries 7 of different specifications.

[0140] For example, when the battery 7 is a cylindrical battery, by adjusting the opening diameter of the gripper 411, the opening diameter of the gripper 411 can be matched with the diameter of the battery 7, so that cylindrical batteries of different diameters can be clamped.

[0141] According to some embodiments of the present invention, the second transfer unit 4 includes a lifting drive mechanism, which is tractably connected to the clamping mechanism 41 for driving the clamping mechanism 41 to move in the vertical direction.

[0142] By providing a lifting drive mechanism for driving the clamping mechanism 41 to move in the vertical direction, the position of the clamping mechanism 41 in the vertical direction can be adjusted in a timely manner according to the actual situation, so that the clamping mechanism 41 can better clamp the battery 7, or when the clamping mechanism 41 releases the battery 7, the distance between the battery 7 and the processing station 634 is closer, reducing or avoiding friction and wear caused by the battery 7 falling due to excessive distance in the vertical direction.

[0143] For example, when the clamping mechanism 41 is above the rotating unit 2, the lifting drive mechanism drives the clamping mechanism 41 to move downward, so that the clamping mechanism 41 is closer to the battery 7 located at the placement position 221, so as to better clamp the battery 7; as another example, when transferring the battery 7 to the processing station 634, the lifting drive mechanism drives the clamping mechanism 41 to move downward, so that the distance between the clamping mechanism 41 and the processing station 634 in the vertical direction is closer, so that the clamping mechanism 41 can better release the battery 7 to the processing station 634, reducing the friction and wear caused by the battery 7 falling due to the excessive vertical distance; as yet another example, when the rotating unit 2 rotates and the clamping mechanism 41 is above the rotating unit 2, the lifting drive mechanism drives the clamping mechanism 41 to move upward, which can effectively avoid the friction and wear caused by the interference between the clamping mechanism 41 and the rotating unit 2.

[0144] According to some embodiments of the present invention, the second transfer unit 4 includes a rotary drive mechanism 21, which is tractably connected to the clamping mechanism 41 for driving the clamping mechanism 41 to rotate, and the rotation axis of the clamping mechanism 41 extends in the vertical direction.

[0145] By providing a rotary drive mechanism 21 for driving the clamping mechanism 41 to rotate, and the rotation axis of the clamping mechanism 41 extends in the vertical direction, the position of the clamping mechanism 41 in the horizontal direction can be adjusted in a timely manner according to the actual situation, so that the clamping mechanism 41 can better clamp the battery 7, or when the clamping mechanism 41 releases the battery 7, the direction of the battery 7 is aligned with the processing station 634, so that the battery 7 can be better placed into the processing station 634.

[0146] For example, the clamping mechanism 41 includes multiple grippers 411 to simultaneously grip multiple batteries 7, improving the efficiency of loading. When the battery 7 is in the rotating unit 2, the multiple batteries 7 are placed along the first direction. When the battery 7 is in the processing station 634, the multiple batteries 7 are placed along the second direction. By driving the grippers 411 to rotate around their own rotation axis through the rotation drive mechanism 21, the clamping mechanism 41 can be flexibly turned to better grip or release the battery 7. Furthermore, by integrating the transfer and turning functions into the clamping mechanism 41, the need for additional mechanisms for turning the battery 7 can be eliminated, saving the overall space occupied by the loading system 100.

[0147] Reference Figures 1-4According to a second aspect embodiment of the present invention, a battery welding system 1000 includes a feeding system 100 and a welding turntable 200. The feeding system 100 is the feeding system 100 of the first aspect embodiment of the present invention described above. The welding turntable 200 includes a welding turntable 61 and a turntable driving mechanism 62. The turntable driving mechanism 62 is connected to the welding turntable 61 and is used to drive the welding turntable 61 to rotate. The welding turntable 61 has a plurality of processing stations 634, which are spaced apart circumferentially along the welding turntable 61.

[0148] The feeding system 100 can adjust the battery 7 to a second placement orientation. For example, the battery welding system 1000 is used to weld the top cover of the battery 7. The feeding system 100 can adjust the battery 7 to a state where the end of the battery 7 faces upward, i.e., the second placement orientation. The central axis of the battery 7 extends vertically to facilitate the processing of the battery 7 on the welding turntable 200. This eliminates the need for additional devices and processes on the welding turntable 200 to adjust and position the orientation of the battery 7. The feeding system 100 can directly feed the battery 7 to the processing station 634. By providing a turntable drive mechanism 62 for driving the welding turntable 61 to rotate, the continuous and orderly flow between the feeding system 100 and multiple processing stations 634 can be achieved by driving the welding turntable 61 to rotate.

[0149] For example, the battery welding system 1000 includes a welding device located on the outer periphery of the welding turntable 61. The welding device includes multiple welding mechanisms that are spaced apart circumferentially along the welding turntable 61 to facilitate welding of the battery 7 located at the processing station 634.

[0150] For example, the loading process of battery 7 can be as follows: when battery 7 is at loading position 111, conveyor belt 11 is used to transport battery 7 to discharge end 121. When battery 7 moves to discharge end 121, first transfer unit 3 can transfer battery 7 from discharge hole 1231 to rotation unit 2. By driving rotating component 22 to rotate through rotation drive mechanism 21, the placement direction of battery 7 can be adjusted from first placement direction to second placement direction. After the placement direction of battery 7 is adjusted to the second placement direction, second transfer unit 4 transfers battery 7 to processing station 634. After battery 7 is placed in processing station 634, turntable drive mechanism 62 drives welding turntable 61 to rotate, so that battery 7 in processing station 634 rotates to welding mechanism for welding.

[0151] According to an embodiment of the present invention, the battery welding system 1000, by providing the aforementioned feeding system 100, and by providing a first transfer unit 3 for transferring the battery 7 located at the discharge end 121 of the conveying unit 1 to the rotating member 22, can promptly transfer the battery 7 located at the discharge end 121 to the rotating unit 2, so that the rotating unit 2 can adjust the placement direction of the battery 7; and by providing the rotating unit 2, which includes a rotation drive mechanism 21 and a rotating member 22, the rotation drive mechanism 21 can drive the rotating member 22 to rotate, thereby adjusting the placement direction of the battery 7 placed at the placement position 221 of the rotating member 22, relative to the relevant The manual rotation and slide rail guided rotation in the technology, the rotation drive mechanism 21 can provide high-precision angle control function, can accurately adjust the placement direction of the battery 7 to the second placement direction, which can effectively improve the accuracy of the placement direction of the battery 7 after adjustment, so as to facilitate the subsequent welding of the battery 7 on the welding turntable 200, and the operation efficiency is high. It eliminates the need to set up an additional device on the welding turntable 200 for adjusting the direction of the battery 7, and correspondingly eliminates the process of adjusting and positioning the direction of the battery 7 on the welding turntable 200, thereby helping to optimize the overall production efficiency of the battery welding system 1000.

[0152] Reference Figures 21-25 According to some embodiments of the present invention, the welding turntable 200 includes a plurality of welding positioning fixtures 63, which are disposed on the welding turntable 61 and arranged at intervals along the circumference of the welding turntable 61. Each welding positioning fixture 63 includes a positioning seat 631 and a fixture driving mechanism 635. The positioning seat 631 includes a first positioning seat 632 and a second positioning seat 633. The first positioning seat 632 and the second positioning seat 633 together define the work station 634 to be processed. The first positioning seat 632 is fixed to the welding turntable 61. The fixture driving mechanism 635 is used to move the second positioning seat 633 relative to the first positioning seat 632 to adjust the size of the work station 634 to be processed. By providing a clamping drive mechanism 635 for driving the second positioning seat 633 to move relative to the first positioning seat 632, the size of the processing station 634 can be adjusted by adjusting the distance between the second positioning seat 633 and the first positioning seat 632, so that the size of the processing station 634 of the welding positioning fixture 63 is precisely matched with the specifications of the battery 7 fed by the feeding system 100, so that the battery welding system 1000 can weld batteries 7 of various sizes.

[0153] For example, when the size of the battery 7 is larger than the size of the workstation 634, the second positioning seat 633 can be moved relative to the first positioning seat 632 by the clamping drive mechanism 635, so as to increase the distance between the first positioning seat 632 and the second positioning seat 633, so that the battery 7 can be placed in the workstation 634.

[0154] Reference Figures 21-25 According to some embodiments of the present invention, the second positioning seat 633 is located radially inner to the first positioning seat 632 along the welding turntable 61, and the second positioning seat 633 is radially movable along the welding turntable 61. By positioning the second positioning seat 633 radially inner to the first positioning seat 632 along the welding turntable 61 and being radially movable along the welding turntable 61, the distance between the first positioning seat 632 and the second positioning seat 633 can be increased or decreased by moving the second positioning seat 633, thereby adjusting the size of the processing station 634. This allows the processing station 634 to accommodate batteries 7 of different sizes. Furthermore, when the second positioning seat 633 moves, the internal space of the welding turntable 61 can be fully utilized, preventing the second positioning seat 633 from occupying external space of the welding turntable 61 and interfering with the feeding system 100.

[0155] Reference Figures 21-25 According to some embodiments of the present invention, the second positioning seat 633 is provided with a first mating protrusion 6331, and the output end of the clamping drive mechanism 635 is provided with a second mating protrusion 6351. The second mating protrusion 6351 is located radially outside the first mating protrusion 6331 along the welding turntable 61, and the second mating protrusion 6351 is adapted to abut or separate from the first mating protrusion 6331. The clamping drive mechanism 635 is used to drive the second positioning seat 633 to move in a direction away from the first positioning seat 632. The first mating protrusion 6331 can enhance the structural strength of the second positioning seat 633 to a certain extent, and the second mating protrusion 6351 can enhance the structural strength of the clamping drive mechanism 635 to a certain extent.

[0156] By abutting the first mating protrusion 6331 and the second mating protrusion 6351, the clamping drive mechanism 635 can apply a driving force to the second positioning seat 633 to drive the second positioning seat 633 to move away from the first positioning seat 632, thereby increasing the distance between the second positioning seat 633 and the first positioning seat 632, increasing the size of the processing station 634, and making it easier to put a larger battery 7 into the processing station 634.

[0157] By separating the first mating protrusion 6331 from the second mating protrusion 6351, the driving force of the clamp drive mechanism 635 on the second positioning seat 633 can be eliminated.

[0158] Reference Figures 21-25 According to some embodiments of the present invention, the welding positioning fixture 63 further includes an elastic reset mechanism 636, which is mounted on the welding turntable 61 and connected to the second positioning seat 633 for driving the second positioning seat 633 to move toward the first positioning seat 632 for clamping the battery 7 located at the processing station 634.

[0159] The welding turntable 61 is equipped with an elastic reset mechanism 636. The elastic force of the elastic reset mechanism 636 can be used to drive the second positioning seat 633 to move toward the direction close to the first positioning seat 632, so as to provide a better clamping force for the battery 7 located in the processing station 634, so that the battery 7 is more stably located in the processing station 634.

[0160] For example, when the size of the battery 7 is smaller than the size of the processing station 634, the second positioning seat 633 can be moved relative to the first positioning seat 632 by the elastic reset mechanism 636, so as to reduce the distance between the first positioning seat 632 and the second positioning seat 633, so that the first positioning seat 632 and the second positioning seat 633 cooperate to provide a better clamping force for the battery 7, so that the battery 7 is more stably located in the processing station 634, reducing the possibility of the battery 7 shifting.

[0161] For example, the transfer process of battery 7 between the loading system 100 and the welding turntable 200 can be as follows: the loading system 100 transfers battery 7, located in the second placement direction, to a position above and opposite the positioning seat 631. The second mating protrusion 6351 of the clamping drive mechanism 635 abuts against the first mating protrusion 6331 of the second positioning seat 633, thereby driving the second positioning seat 633 to move away from the first positioning seat 632. At this time, the elastic reset mechanism 636 is in a compressed state, which can increase the size of the battery to be welded. The dimensions of the workstation 634 are designed to allow the feeding system 100 to place the battery 7 into the workstation 634. After the battery 7 is placed into the workstation 634, the second mating protrusion 6351 separates from the first mating protrusion 6331. At this time, the elastic reset mechanism 636 is driven by its own elastic force to move the second positioning seat 633 toward the direction of the first positioning seat 632, so that the first positioning seat 632 and the second positioning seat 633 work together to clamp the battery 7, so that the battery 7 is relatively stably located in the workstation 634.

[0162] Reference Figures 21-25 According to some embodiments of the present invention, the welding turntable 200 includes a turntable frame 64, the turntable frame 64 includes a mounting plate 641, the mounting plate 641 is located above the welding turntable 61, the positioning seat 631 is located on the outer periphery of the mounting plate 641, and the clamping drive mechanism 635 is mounted on the mounting plate 641. By positioning the mounting plate 641 above the welding turntable 61, the space above the welding turntable 61 can be fully utilized, reducing the occupancy of the external space of the welding turntable 61.

[0163] With the positioning seat 631 located on the outer periphery of the mounting plate 641 and the clamping drive mechanism 635 mounted on the mounting plate 641, the clamping drive mechanism 635 can easily drive the second positioning seat 633 to move relative to the first positioning seat 632. Furthermore, since the mounting plate 641 is fixed, the rotation of the welding turntable 61 can achieve the abutment or separation between the second mating protrusion 6351 provided on the clamping drive mechanism 635 and the first mating protrusion 6331 provided on the second fixed seat.

[0164] For example, when the welding turntable 61 rotates to the point where the second mating protrusion 6351 abuts against the first mating protrusion 6331, the clamping drive mechanism 635 provides a driving force to the second positioning seat 633 to drive the second positioning seat 633 to move away from the first positioning seat 632, thereby increasing the distance between the second positioning seat 633 and the first positioning seat 632 and increasing the size of the processing station 634; as another example, when the welding turntable 61 rotates to the point where the first mating protrusion 6331 separates from the second mating protrusion 6351, the elastic force of the elastic reset mechanism 636 drives the second positioning seat 633 to move towards the first positioning seat 632 to clamp the battery 7 located at the processing station 634.
