Description

Technical Field

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

[0002] The battery pole is a key component that connects the internal electrode of the battery with the external circuit. It not only carries the task of current transmission, but also affects the sealing, reliability and safety of the battery. Traditionally, battery poles are mostly made of metal materials, such as lead, aluminum or copper, which have good conductivity and mechanical strength. However, there are many challenges in the production process: on the one hand, the pole needs to adapt to complex geometric shapes to match different battery designs, which increases the difficulty of molding; on the other hand, in order to ensure good conductive contact, the pole surface must be smooth and defect-free, which places strict requirements on processing accuracy. Therefore, each step of the traditional manufacturing process may introduce variability, thereby affecting the quality of the final product.

[0003] In order to solve the above-mentioned problems, the casting process has begun to be widely used in the prior art to make battery poles. Casting is a method of forming a specific shape by injecting molten metal into a mold. It can complete the molding of complex structures in one go, greatly simplifying the production process and reducing the cumulative errors caused by multiple processes. Especially for poles that require highly customized designs, the casting process can more flexibly meet the needs of different specifications. At the same time, advanced casting techniques (such as low-pressure casting and pressure casting) can also control the cooling rate and solidification process, making the internal structure of the casting denser and the surface quality better, thereby improving the mechanical strength and conductivity of the pole and enhancing the reliability of the product.

[0004] Although the casting process has greatly improved the manufacturing of battery poles, there are still some problems that need to be solved in practical applications. The first is the problem of yield rate. Since defects such as pores and cracks will inevitably appear during the casting process, these defects will directly affect the quality of the pole, reduce its electrical performance and mechanical strength, and lead to a high defective rate. Secondly, with the growth of market demand for batteries, the existing casting production lines are facing the pressure of insufficient production capacity. Traditional casting equipment and technology are difficult to respond quickly to changes in market demand and cannot achieve efficient large-scale production. Therefore, how to improve the yield rate and expand production capacity through manufacturing processes or improved manufacturing equipment has become a technical problem that urgently needs to be solved.

[0058] In some embodiments, the connection portion of the first mounting seat 21 can penetrate into the slide mechanism 23 through a slide rail, and the connection portion has an assembly hole for sleeve-mounted a screw rod, and the assembly hole can be embedded with a ball nut, so that the ball nut is configured on the screw rod, thereby forming a screw rod and nut kinematic pair.

[0059] Further, see Figure 1 As shown, in some embodiments, the fixed module 1 includes: a first stamping station 11, which is used to provide the blank for the forming process; a second stamping station 12, which is used to provide the blank for the punching process; a third stamping station 13, which is used to provide the blank for the stamping knurling process; a fourth stamping station, which is used to provide the blank for the blank for the blanking process;

[0060] The first stamping station 11, the second stamping station 12, the third stamping station 13 and the fourth stamping station are arranged in a straight line; a material taking station 14 is also provided on the fixed module 1, and the material taking station 14 is located on the side of the first stamping station 11 away from the second stamping station 12;

[0061] Among them, when the gripping mechanism moves to the material discharge area, each suction cup arm 26 on the gripping mechanism corresponds one by one to the first stamping station 11, the second stamping station 12, the third stamping station 13 and the fourth stamping station; when the gripping mechanism moves to the material picking area, each suction cup arm 26 on the gripping mechanism corresponds one by one to the material picking station 14, the first stamping station 11, the second stamping station 12 and the third stamping station 13.

[0062] Specifically, in the technical solution adopted in the present application, the grasping device 2 may include: a slide mechanism 23 and a first driving mechanism, a second driving mechanism and a grasping mechanism installed on the slide mechanism 23.

[0063] In some embodiments, the slide mechanism 23 has a slide rail extending along a first direction, and the first direction is the layout direction of each stamping station on the fixed module 1. Therefore, after the grabbing mechanism is slidably arranged on the slide mechanism 23 through the slide rail, the blank can be transferred to each stamping station of the fixed module 1. The first driving mechanism is used to drive the grabbing mechanism to slide on the slide mechanism 23 through the slide rail, and the second driving mechanism is used to drive the grabbing mechanism to rise and fall along the second direction to grab or place the blank.

[0064] In one embodiment, the first driving mechanism may include: a servo motor 24 fixedly mounted on one side of the slide mechanism 23, and a lead screw rotatably arranged inside the slide mechanism 23, the extension direction of the lead screw is the same as the extension direction of the slide rail, both are the first direction, the lead screw is connected to the output shaft of the servo motor 24 for synchronous rotation, it can be understood that the servo motor 24 can drive the lead screw to rotate inside the slide mechanism 23; and the connecting part of the grasping mechanism is threadedly mounted on the lead screw, so that a lead screw nut kinematic pair is formed inside the slide mechanism 23 through the connecting part of the grasping mechanism and the lead screw, so that when the lead screw is driven by the servo motor 24, a driving force can be applied to the grasping mechanism to drive the grasping mechanism to slide on the slide.

[0065] In one embodiment, the second driving mechanism can be a driving cylinder 25 arranged on the grasping mechanism, and the grasping mechanism can include: a first mounting seat 21 and a second mounting seat 22, the first mounting seat 21 is arranged on the slide mechanism 23 through a slide rail, and has a connecting portion sleeved on the screw rod, and the connecting portion has an internal thread structure adapted to the external thread of the screw rod. The second mounting seat 22 can be connected to the top of the first mounting seat 21 through the driving cylinder 25, and the second mounting seat 22 can be provided with the same number of suction cup arms 26 as the number of stamping stations on the fixed module 1, and each suction cup arm 26 is arranged at intervals, and the interval between two adjacent suction cup arms 26 is equal to the interval between two adjacent stamping stations. In this embodiment, the cylinder body of the driving cylinder 25 can be fixedly installed on the second mounting seat 22, and the piston rod of the driving cylinder 25 is connected to the first mounting seat 21, so that when the piston rod of the driving cylinder 25 is extended and retracted, the driving cylinder 25 can drive the second mounting seat 22 away from or close to the first mounting seat 21 along the second direction, thereby realizing the suction cup arm 26 to complete the descending picking and placing action and the ascending lifting action above the fixed module 1.

[0066] In one embodiment, the number of rotations of the servo motor 24 can be preset to set the material picking area, material discharge area, and the clearance area between the material picking area and the material discharge area of ​​each suction cup arm 26. Specifically, the blank is transported to the material picking station 14 on the fixed module 1 by the conveying mechanism, and the fixed module 1 can also be provided with a first stamping station 11, a second stamping station 12, a third stamping station 13, and a fourth stamping station arranged in sequence, wherein the first stamping station 11 is closest to the material picking station 14. When in use, when each suction cup arm 26 is in the material picking area, each suction cup arm 26 corresponds to the material picking station 14, the first stamping station 11, the second stamping station 12, and the third stamping station 13, respectively, and the suction cup arm 26 is lowered by driving the cylinder 25 to adsorb the blank on the suction cup arm 26. When each suction cup arm 26 is in the material discharge area, each suction cup arm 26 corresponds to the first stamping station 11, the second stamping station 12, the third stamping station 13 and the fourth stamping station, respectively, and the blank is placed on each stamping station by driving the cylinder 25 to lower the suction cup arm 26. When each suction cup arm 26 is in the yielding area, each suction cup arm 26 is divided into being located between the material taking station 14 and the first stamping station 11, between the first stamping station 11 and the second stamping station 12, between the second stamping station 12 and the third stamping station 13, and between the third stamping station 13 and the fourth stamping station, so that each suction cup arm 26 can avoid the path of the punch to the stamping station.

[0067] In some embodiments, a conveying mechanism is also included for conveying the blank to the material taking station 14. The conveying mechanism may include a vibration plate 3 and a vibration track 4. The vibration plate 3 is connected to the material taking station 14 on the fixed module 1 through the vibration track 4, so as to realize the orderly transportation of the blank to the fixed module 1. Since the vibration plate 3 and the vibration track 4 both use vibration as a driving force, unnecessary trouble will not be caused by the accumulation of blanks. The specific vibration driving force of the vibration track 4 comes from a vibrator, and a vibrator is configured on the vibration track 4, so that starting the vibrator can apply a vibration force to the vibration track 4, so that the blank on the vibration track 4 moves toward the direction close to the material taking station 14.

[0068] A method for manufacturing a battery pole is proposed in the second embodiment of the present application. The method may include: transporting a blank material to a designated material taking station 14 through a conveying mechanism;

[0069] When the stamping die enters the mold opening state, the gripping device 2 is moved to the material picking area, and the gripping device 2 is driven to pick up the blank on the material picking station 14 and the blanks of each stamping station on the stamping die;

[0071] After the gripping device 2 is moved to the clearance area, the stamping die is started to enter the mold closing state to perform the stamping process on the blanks on each target station;

[0072] The displacement grabbing action of the grabbing device 2 and the punching action of the punching die are repeated until the blank is made into a pole product.

[0073] Furthermore, in some embodiments, when the stamping die enters the mold opening state, the step of moving to the material picking area by the gripping device 2 and picking up the material picking station 14 and the blanks of each stamping station on the stamping die also includes:

[0074] The grabbing machine moved to the material picking area is driven to move downward to absorb the blanks at the material picking station 14 and the blanks at each stamping station on the stamping die; the grabbing device 2 moved to the material picking area is driven to move upward to lift the absorbed blanks, completing the pre-preparation for moving to the material discharge area.

[0075] Further, in some embodiments, the step of controlling the gripping device 2 to move to the material placing area to place the blank of the material taking station 14 on the stamping station for the first process on the stamping die, and the gripping device 2 also placing the blank on the stamping die on the target station for the next stamping process further includes:

[0076] The grabbing device 2 moved to the material discharge area is driven to translate downward to place the blank on each stamping station of the stamping die; the grabbing device 2 moved to the material discharge area is driven to translate upward to complete the preliminary preparation for moving the grabbing device 2 to the clearance area.

[0077] Furthermore, in some embodiments, after the gripping device 2 is moved to the clearance area, the stamping die is started to enter the mold closing state to perform the stamping process on the blanks on each target station, and the step also includes:

[0078] When the stamping die is in the mold closing state: the blank is moved from the material taking station 14 to the first stamping station 11 for the forming process; the blank is moved from the first stamping station 11 to the second stamping station 12 for the punching process; the blank is moved from the second stamping station 12 to the third stamping station 13 for the stamping knurling process; the blank is moved from the third stamping station 13 to the fourth stamping station for the blanking process.

[0079] Reference Figure 4 As shown, it needs to be explained that the knurling process can be performed by punching the knurling structure 100 on the battery pole through the third stamping station 13.

[0080] Furthermore, in some embodiments, after the gripping device 2 is moved to the clearance area, the stamping die is started to enter the mold closing state to perform the stamping process on the blanks on each target station, and the step also includes:

[0081] The making way area is located between the material picking area and the material putting area, and after the grasping device 2 is in the making way area, each manipulator of the grasping device 2 is respectively located between adjacent target stations on the stamping die, so that after the stamping die enters the mold closing state, the punch penetrates into the gap between the adjacent manipulators to punch the blank on the target station.

[0082] Specifically, in the technical solution adopted in the present application, the function of the conveying mechanism is to transfer the blank from the storage position to the designated material picking station 14. The conveying mechanism can be in various forms, such as a conveyor belt, a mechanical arm, a vibration plate 3 and a track combination, etc., and its purpose is to ensure that the blank can reach the material picking station 14. The material picking station 14 is the starting point for subsequent operations and provides a source of raw materials for subsequent grasping and processing operations. Its location setting needs to take into account the coordination and operational convenience with other parts of the entire device to ensure the continuity and efficiency of production. The open mold state means that the upper and lower molds of the stamping mold are in a separated state, which provides an operating space for the grasping device 2 to avoid collision with the mold when grasping the blank. The opening and closing action of the stamping mold is usually driven by a hydraulic system, a pneumatic system or an electric system, and the timing of its action needs to be precisely coordinated with the action of the grasping device 2 to ensure the smoothness of the entire production process. The gripping device 2 will move to the material picking area, which is a pre-set position. Its position selection should take into account the relative position relationship with the material picking station 14 and each stamping station on the stamping die, so that the blank can be easily grabbed. This movement process can be achieved through guide rails, sliders, and components such as drive motors or cylinders to ensure that the gripping device 2 can accurately reach the predetermined position. When the gripping device 2 arrives at the material picking area, it will grab the blanks on the material picking station 14 and the blanks on each stamping station on the stamping die. The picking action here can be carried out in a variety of ways, such as through mechanical claws, suction cups or magnetic devices. For blanks of different shapes and materials, different gripping methods can be selected. For example, for metal blanks, suction cups or magnetic suction may be more suitable; for some irregularly shaped blanks, mechanical claws may be more advantageous. Its purpose is to lift the blanks that need further processing from their location to prepare for subsequent process transfer. After the blank is grabbed, the grabbing device 2 will be controlled to move to the discharge area, and the grabbing device 2 can place the blank on the corresponding stamping station. In the discharge area, the grabbing device 2 will place the blank grabbed from the material picking station 14 on the stamping station for the first process on the stamping die. At the same time, for the blank that has already passed the previous process on the stamping die, the grabbing device 2 will place it on the target station for the next stamping process. This operation realizes the orderly transfer of blanks between different processes and ensures the continuity of the production process. For example, if the first process is forming, the blank from the material picking station 14 will be placed on the forming station; for the already formed blank, it will be transferred to the next process, such as the station corresponding to the punching, knurling or blanking process, so that the blank is gradually processed according to the predetermined process flow. After the blank is placed, the grabbing device 2 will move to the clearance area. The position of the clearance area should ensure that the gripping device 2 will not interfere with the punch or other moving parts of the mold when the stamping mold is in the mold closing operation.Such a design can avoid collision and damage between devices, and also ensure that the stamping die can perform stamping operations normally. When the gripping device 2 enters the clearance area, the stamping die enters the mold closing state. The mold closing state refers to the closure of the upper and lower molds of the stamping die, and the punch is used to apply pressure to the blank placed on each stamping station to complete the corresponding stamping process. During the mold closing process, according to different stations, the blank will be processed into different shapes or complete different process treatments, such as forming, punching, knurling, blanking, etc. These processes are determined according to the design requirements and production process of the battery pole. The punch shape, pressure size and stroke of each station may be different to achieve accurate processing of the blank. In order to gradually process the blank into the final battery pole product, the above-mentioned operation steps need to be repeated continuously. This cyclic operation is the core of automated production. Through multiple displacement grasping and stamping actions, the blank is sequentially processed through various processing steps and finally converted into a pole product that meets the requirements. During the cycle, each cycle brings the blank one step closer to the shape and performance of the final product.
