Description

Technical Field

[0001] This invention relates to the field of battery module manufacturing technology, and in particular to a cutting device for battery module connecting pieces. Background Technology

[0002] Battery cells are the power supply devices for electric vehicles and are an important component of electric vehicles. Battery module connectors are important structures used to connect batteries, and they are often produced using laser cutting.

[0003] Chinese patent document CN220291015U discloses a connecting piece, a battery module, and a vehicle. The connecting piece includes a connecting piece body, which is bent in a direction perpendicular to itself, forming a bent portion and a welded portion. A connecting structure is formed on the bent portion, and a bent buffer structure is formed between the connecting structure and the welded portion. This invention can solve the problem of detachment or tearing at the welding position between the connecting piece and the battery cell due to the increased spacing between adjacent battery cells caused by cell expansion.

[0004] The existing technology has the following problems: Existing battery connectors often have bending sections in their overall structure. These sections are typically bent using stamping. If material is removed directly by stamping, the resulting connectors may have poor cross-sectional quality and prominent burrs, requiring subsequent grinding and resulting in a short mold life. Therefore, it is necessary to use laser cutting to form standard parts before stamping, and then use stamping without removing material to form the finished part. However, this method results in the laser-cut standard parts being scattered and stacked, affecting the subsequent feeding of the stamping machine. Material removal stamping, in its core, uses the shearing and separating action of a mold to peel and remove a portion of the material from the parent material, thereby obtaining a part or semi-finished product of the required shape and size. It is also often referred to as blanking stamping or separation processes, and is a concept relative to forming processes such as bending, stretching, and forming that "do not remove material but only change the shape of the material." Summary of the Invention

[0005] The main objective of this invention is to provide a cutting device for battery module connecting pieces, which can effectively solve the problem of difficulty in feeding materials before stamping caused by first using laser cutting and then stamping to change the shape.

The two ends of the guide rail are fixedly connected to the left and right sides of the inner side of the cavity base. A motor is fixedly connected to the rear side of the movable frame near the upper side. The output end of the motor is fixedly connected to several linearly distributed cleaning wheels through rods. The cleaning wheels are used to remove welding slag on the mounting platform located in front. An L-shaped slag collection frame is fixedly connected to the lower side of the movable frame. The L-shaped slag collection frame and the front wall of the L-shaped mounting platform combine to form a U-shaped frame with an opening to the right. A discharge port is provided at the bottom right side of the cavity base.

[0011] Preferably, the bottom round rod of the movable frame is rotatably connected to a torsion spring-driven push plate connected by a rod. The push plate is located on the right side of the L-shaped slag collection frame. A push plate is fixedly connected to the top of the push plate. When the push plate is in a vertical state, the push plate is in a horizontal state. A limiting groove is opened at the bottom inner side of the L-shaped mounting platform. The limiting groove is arranged in three sections from left to right. The middle section is trapezoidal, and the left and right sections are rectangular. The trapezoidal block in the lower middle part of the push plate is slidably connected to the inner side of the limiting groove. A U-shaped guide frame for pushing the push plate is fixedly connected to the left inner side of the cavity base.

[0012] Preferably, the lower wall of the U-shaped guide frame is slidably connected to a spring-driven slide rod, the lower surface of the slide rod is coplanar with the lower surface of the U-shaped guide frame, and the slide rod and the push plate are made of magnetic materials that attract each other.

[0013] Preferably, the stabilizing mechanism includes a lifting plate for electromagnetic adsorption of the adsorption plate, a plurality of second limiting rods fixedly connected to the upper side of the lifting plate, and a moving platform sleeved on the outer side of the second limiting rods. A plurality of evenly distributed hydraulic rods are fixedly connected to the upper side of the moving platform, and the outer side of the hydraulic rods is fixedly connected to the top of the inner side of the enclosed shell. When the moving mechanism drives the laser cutting mechanism to move to the upper side of the feeding mechanism, the lifting plate is located on the upper side of the laser cutting mechanism. A third spring is sleeved on the outer side of each of the plurality of second limiting rods and is located on the lower side of the moving platform. A first spring located in the mechanism hole is sleeved on the outer side of each of the plurality of ventilation rods, and an end ring is fixedly connected to the lower side of the plurality of ventilation rods.

[0014] Preferably, a plurality of horizontally distributed hydraulic cylinders are fixedly connected to the inner front of the enclosed shell, and piston rods are movably sleeved on the inner side of each of the hydraulic cylinders.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1, as Figures 1-4 As shown, a cutting device for battery module connecting pieces includes a cavity base 1 and a closed shell 2 fixedly connected to the upper side of the cavity base 1. The closed shell 2 is provided with a control panel for operating the device. The inner side of the closed shell 2 is provided with a moving mechanism 7 and a laser cutting mechanism 10 driven by the moving mechanism 7. The moving mechanism 7 is a common mobile device that drives a screw to rotate by an electric motor, thereby realizing the forward and backward and left and right movement of the laser cutting mechanism 10.

[0021] The bottom of the front and rear sides of the enclosed housing 2 is provided with material passage slots 3 for the sheet metal to pass through. At the same time, the front wall of the enclosed housing 2 is provided with a rotating door panel. The material passage slots 3 on the front side can be set on the rotating door panel. Without affecting the movement of the sheet metal, the equipment inside the enclosed housing 2 can also be maintained by rotating the door panel. The upper side of the cavity base 1 near the front side is provided with a limiting mechanism 6. The limiting mechanism 6 is composed of two electrically driven rollers that move relative to each other. The rollers move close to each other to limit the sheet metal. The rotation of the rollers drives the sheet metal to move back and forth. The inner cavity of the cavity base 1 near the rear side is provided with a feeding mechanism 8. The inner side of the enclosed housing 2 is provided with a stabilizing mechanism 9 located above the feeding mechanism 8. The laser cutting mechanism 10 is located inside the stabilizing mechanism 9.

[0022] Example 2, as Figures 5-8As shown, the feeding mechanism 8 includes a rotating tube 81, two rotating components 82 located at both ends of the rotating tube 81, and several connecting frames 83 fixedly connected to the outside of the rotating tube 81. The rotating components 82 are used to drive the rotating tube 81 to rotate. The rotating components 82 contain a motor and a reducer for driving the rotating tube 81 to rotate. Three ring-shaped mounting platforms 84 are fixedly connected to the outside of the connecting frames 83. The mounting platforms 84 are composed of multiple equidistant serrated plates. The shape of the mounting platforms 84 is such that when the sheet is placed on the mounting platform 84, the laser cutting mechanism 10 cuts the sheet to minimize damage to the mounting platforms 84. An opening is provided on the upper side of the cavity base 1 near the rear side for the uppermost mounting platform 84 to pass through.

[0023] Preferably, both rotating components 82 are provided with reciprocating components 86 on their outer sides for driving the rotating tube 81 to reciprocate up and down. The reciprocating components 86 contain components such as cams, return springs, and limiting protrusions. When the rotating tube 81 rotates, it drives the cam to rotate. The limiting protrusion pushes the cam and, with the help of the return spring, the rotating tube 81 reciprocates up and down. When the rotating tube 81 rotates 120 degrees, it completes a full cycle of up and down reciprocating motion. When the rotating tube 81 rotates 60 degrees, it is at its lowest position. The up and down movement of the rotating tube 81 avoids the problem of the mounting platform 84 and the inner surface of the upper wall of the cavity base 1 being too close due to direct rotation, which could cause scratches. It also avoids the problem of large interference between the cut standard parts and the sheet metal when rotating.

[0024] Each of the three mounting platforms 84 has an adsorption component 85 embedded inside. The adsorption component 85 is used to adsorb the cut standard parts to prevent the standard parts from falling off the mounting platform 84 when the rotating tube 81 rotates. The adsorption component 85 is located between the serrated plates on the mounting platform 84. The rear side of the cavity base 1 near the bottom has a feed port 5. The strip-shaped stamping bottom die is put into the feed port 5. The cut standard parts are put into the stamping bottom die. The stamping bottom die is an existing strip-shaped component with multiple linearly and evenly arranged bottom die grooves. Using a feeding mechanism, such as a robotic arm, the stamping bottom die is directly put into the feed port 5 and sent to the lower side of the rotating tube 81.

[0025] It should be noted that the adsorption component 85 adsorbs the cut standard parts, and the rotating component 82 drives the rotating tube 81 to rotate backward, so that the adsorption component 85 drives the standard parts to rotate backward. The standard parts on the original front and rear mounting platform 84 will move forward. When it passes the lowest position, the rotating tube 81 is exactly at the lowest position. At this time, the adsorption component 85 at the lowest position releases the adsorption of the standard parts, so that the standard parts enter the stamping bottom die, completing the loading of the standard parts.

[0026] Preferably, the adsorption assembly 85 includes an adsorption plate 851, several adsorption seats 852 fixedly connected to the adsorption plate 851 on opposite sides, and several ventilation rods 853 fixedly connected to the adsorption plate 851 on opposite sides. The inner cavity of the ventilation rod 853 is connected to the inner cavity of the adsorption seat 852. The outer side of the ventilation rod 853 is movably sleeved in the mechanism hole opened on the outer side of the connecting frame 83. Two air guide platforms 88 are rotatably connected to the outer side of the rotating tube 81 near the left and right sides. The inner cavity of the adsorption seat 852, the inner cavity of the rotating tube 81, and the inner cavity of the air guide platform 88 are connected. An air pump connected to the air guide platform 88 draws air into the rotating tube 81 and releases air. The adsorption seat 852 adsorbs the cut standard parts.

[0027] Two first limiting rods 89, distributed front and rear, are sleeved on both sides of the two air guide platforms 88 via plates. A second spring 810 with a damping structure is sleeved on the outer side of each of the four first limiting rods 89 and located on the lower side of the plate. The second spring 810 pushes the air guide platform 88 to assist the air guide platform 88 in resetting during the up and down movement of the rotating tube 81. The damping structure avoids the impact of vibration on the second spring 810.

[0028] Example 3, as Figures 9-11 As shown, a cleaning assembly 87 is provided on the inner side of the cavity base 1 in front of the connecting frame 83. The cleaning assembly 87 includes a guide rail 871, an L-shaped mounting platform 877 fixedly connected to the bottom of the inner side of the cavity base 1, and a movable frame 872 that is electrically driven to move left and right along the guide rail 871. The movable frame 872 moves left and right on the guide rail 871. A rack can be set on the guide rail 871, and the motor drives the gear to rotate, so as to achieve the purpose of moving the movable frame 872 on the guide rail 871.

[0029] The two ends of the guide rail 871 are fixedly connected to the left and right sides of the inner side of the cavity base 1. The rear side of the moving frame 872 is fixedly connected to the upper side of the motor 873. The output end of the motor 873 is fixedly connected to several linearly distributed cleaning wheels 874 through rods. Two cleaning wheels 874 form a group. The length of the guide rail 871 is greater than the length of the mounting platform 84, so that when the moving frame 872 is located at both ends of the guide rail 871, the cleaning wheels 874 are located on both sides of the mounting platform 84, which does not affect the rotation of the mounting platform 84. The cleaning wheels 874 are used to remove welding slag on the mounting platform 84 located on the front side. The motor 873 drives the cleaning wheels 874 to rotate, so that the cleaning wheels 874 clean the sides of the serrated plate on the mounting platform 84. The lower side of the moving frame 872 is fixedly connected to an L-shaped slag collection frame 876. The L-shaped slag collection frame 876 and the front wall of the L-shaped mounting platform 877 combine to form a U-shaped frame with an opening to the right. The bottom right side of the cavity base 1 is provided with a discharge port 4.

[0030] It should be noted that the moving frame 872 moves left and right on the guide rail 871. When the serrated plate on the mounting platform 84 gets into the cleaning wheel 874, the cleaning wheel 874 removes the welding slag on the mounting platform 84. The welding slag generated by the cleaning falls into the L-shaped slag collection frame 876. As the moving frame 872 moves to the right, it drives the L-shaped slag collection frame 876 to move to the right. The L-shaped slag collection frame 876 drives the welding slag to move towards the discharge port 4.

[0031] Preferably, the bottom round rod of the movable frame 872 is rotatably connected to a torsion spring-driven push plate 875 connected by a rod. The push plate 875 is located on the right side of the L-shaped slag collection frame 876. The top of the push plate 875 is fixedly connected to a push plate 879. When the movable frame 872 moves to the right, it will simultaneously drive the push plate 875 to move to the right. The push plate 875 pushes the stamping bottom die to the right, realizing the automatic unloading of the stamping bottom die.

[0032] When the push plate 875 is in a vertical position, the push plate 879 is in a horizontal position. A limiting groove 8711 is provided on the inner bottom of the L-shaped mounting platform 877. A sliding bar is provided on the lower side of the L-shaped slag collection frame 876 to seal the limiting groove 8711 between the inner side of the L-shaped slag collection frame 876 and the push plate 875, preventing welding slag from falling into the limiting groove 8711. The limiting groove 8711 is arranged in three sections from left to right; the middle section is trapezoidal, and the sections on the left and right sides are rectangular. The trapezoidal block at the lower center of 875 is slidably connected to the inner side of the limiting groove 8711. When the trapezoidal block slides into the rectangular section of the limiting groove 8711, the limiting groove 8711 no longer restricts the push plate 875, causing the push plate 875 to rotate under the drive of the torsion spring. A U-shaped guide frame 878 for pushing the push plate 879 is fixedly connected to the inner left side of the cavity base 1. When the moving frame 872 moves from right to left, the U-shaped guide frame 878 pushes the push plate 879, causing the push plate 879 to rotate to a horizontal state.

[0033] It should be noted that when the moving frame 872 is located at the far left, the push plate 879 is in a horizontal state due to the restriction of the U-shaped guide frame 878. After receiving the standard part, the stamping bottom die is moved forward by the feeding mechanism to the right side of the push plate 875. The moving frame 872 moves to the right, so that the trapezoidal block on the lower side of the push plate 875 enters the middle section of the limiting groove 8711, so that the push plate 875 remains in a vertical state. The moving frame 872 continues to move to the right, so that the push plate 875 pushes the stamping bottom die to the right, so that the stamping bottom die moves out of the inner side of the cavity base 1. When the trapezoidal block on the lower side of the push plate 875 slides into the right section of the limiting groove 8711, the limiting groove 8711 no longer restricts the push plate 875. The push plate 875 is driven to rotate by the torsion spring, so that the push plate 875 no longer blocks the L-shaped slag collection frame 876, which facilitates the discharge of welding slag. Subsequently, the moving frame 872 is reset, and the U-shaped guide frame 878 pushes the push plate 879 to reset the push plate 875.

[0034] Preferably, a spring-driven slide rod 8710 is slidably connected to the lower wall of the U-shaped guide frame 878. The lower surface of the slide rod 8710 is coplanar with the lower surface of the U-shaped guide frame 878. The slide rod 8710 and the push plate 879 are made of magnetic materials that attract each other. When the push plate 879 is located under the U-shaped guide frame 878, as the moving frame 872 moves to the right, the push plate 879 attracts the slide rod 8710 and moves to the right synchronously.

[0035] It should be noted that the slide rod 8710 is used to limit the push plate 879, so as to prevent the trapezoidal block on the lower side of the push plate 875 from rotating due to the push plate 879 moving out of the lower side of the U-shaped guide frame 878 when it enters the middle section of the limiting groove 8711.

[0036] Example 4, as Figure 12 and Figure 8 As shown, the stabilizing mechanism 9 includes a lifting plate 91 for electromagnetic adsorption of the adsorption plate 851, several second limiting rods 93 fixedly connected to the upper side of the lifting plate 91, and a moving stage 92 sleeved on the outside of the second limiting rods 93. The lifting plate 91 electromagnetically adsorbs the adsorption plate 851, causing the adsorption plate 851 to move upward, thereby causing the adsorption seat 852 to fit against the lower side of the standard part. In the initial state, the adsorption plate 851 is lower than the uppermost position of the mounting stage 84, avoiding the influence of laser cutting.

[0037] Several evenly distributed hydraulic rods 95 are fixedly connected to the upper side of the moving table 92. The hydraulic rods 95 drive the moving table 92 to move up and down. The outer side of the hydraulic rods 95 is fixedly connected to the top of the inner side of the closed shell 2. When the moving mechanism 7 drives the laser cutting mechanism 10 to move to the upper side of the feeding mechanism 8, the lifting plate 91 is located on the upper side of the laser cutting mechanism 10. The presence of the lifting plate 91 does not affect the operation of the laser cutting mechanism 10. A third spring 94 is sleeved on the outer side of several second limit rods 93 and is located on the lower side of the moving table 92. A first spring 854 located in the mechanism hole is sleeved on the outer side of several ventilation rods 853. The first spring 854 is used to drive the adsorption plate 851 to reset. An end ring is fixedly connected to the lower side of several ventilation rods 853.

[0038] It should be noted that the hydraulic rod 95 drives the moving platform 92 to move up and down, so that the lifting plate 91 is in close contact with the standard part, preventing the standard part from moving freely while the adsorption seat 852 adsorbs the standard part. At the same time, the lifting plate 91 electromagnetically adsorbs the adsorption plate 851 and moves it upward.

[0039] Preferably, a number of horizontally distributed hydraulic cylinders 96 are fixedly connected to the front inner side of the enclosed shell 2. Piston rods 97 are movably sleeved on the inner side of each of the hydraulic cylinders 96. The moving mechanism 7 drives the rear end of the piston rod 97 to move back and forth. The moving mechanism 7 drives the laser cutting mechanism 10 to move forward. When the laser cutting mechanism 10 is disengaged from the upper side of the feeding mechanism 8, it will synchronously drive the piston rod 97 to move forward. The upper side of the hydraulic cylinder 96 is connected to the upper end of the hydraulic rod 95 through an oil supply pipe.

[0040] It should be noted that when the piston rod 97 moves forward, the hydraulic oil in the cylinder 96 enters the hydraulic rod 95, which in turn drives the moving table 92 to move downward. When the laser cutting mechanism 10 resets, it pulls the piston rod 97 to reset, allowing the hydraulic oil to re-enter the cylinder 96, thus completing the reset of the lifting plate 91.

[0041] The working principle of this invention is as follows: First, the adsorption component 85 adsorbs the cut standard part. The rotating component 82 drives the rotating tube 81 to rotate backward, causing the adsorption component 85 to rotate the standard part backward. The standard part on the mounting platform 84, which was originally on the front and back sides, will move forward. When it passes the lowest position, the rotating tube 81 is exactly at its lowest position. At this time, the adsorption component 85 on the lowest side releases its adsorption on the standard part, allowing the standard part to enter the stamping die, completing the loading of the standard part. By rotating the mounting platform 84 driven by the rotating component 82, the standard part is unloaded while the stamping die is loaded, avoiding the standard part being loaded. To address the problem of difficult material loading caused by stacking, the moving frame 872 moves left and right on the guide rail 871. When the serrated plate on the mounting platform 84 gets stuck between the cleaning wheels 874, the cleaning wheels 874 remove the welding slag on the mounting platform 84. The welding slag generated by the removal falls into the L-shaped slag collection frame 876. As the moving frame 872 moves to the right, it drives the L-shaped slag collection frame 876 to move to the right. The L-shaped slag collection frame 876 drives the welding slag to move towards the discharge port 4. By moving the L-shaped slag collection frame 876 through the moving frame 872, the cleaning component 87 removes the welding slag on the mounting platform 84 while unloading the stamping bottom die, reducing maintenance costs.
