Description

Technical Field

[0001] This invention relates to the field of battery copper bar processing, specifically to a punching die for battery copper bars. Background Technology

[0002] There are many types of batteries, such as storage batteries. Storage batteries are an essential part of automobiles and can be divided into traditional lead-acid batteries and maintenance-free batteries. Because storage batteries use a lead-calcium alloy for the grid, the amount of water decomposition during charging is low, and the amount of water evaporation is also low. In addition, the sealed casing structure releases very little sulfuric acid gas. Therefore, compared with traditional batteries, it has advantages such as not needing to add any liquid, easy connection of terminals, and long-term energy storage. To ensure normal charging and discharging, copper electrodes are usually used as the conductive material for the battery electrodes. During the processing of battery copper electrodes, a punching operation is required. However, some existing battery copper electrode punching dies still have some shortcomings in use, such as:

[0003] In existing punching machines, the punched battery copper bar preforms are arranged at equal intervals. Because the preforms cannot be tightly packed, a large portion of the battery copper bar preforms are wasted. Furthermore, for Z-shaped battery copper bars, due to their thinness, the bent ends tend to shift during subsequent punching. Therefore, a pin is needed to position the battery copper bar through a pin hole at the bent end. However, in existing technology, this pin is controlled by a telescopic cylinder, which not only increases the complexity of the device structure but also causes damage to the telescopic cylinder due to the pressure exerted by the punching machine's output during punching, as the working time increases and the pin reacts against the output of the telescopic cylinder.

[0004] Therefore, it is necessary for us to design a punching die for the battery copper bar. Summary of the Invention

[0005] Therefore, it is necessary to provide a punching die for battery copper bars to address the existing technical problems.

[0006] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:

[0007] A punching die for a battery copper bar, comprising:

[0008] The first supporting bracket serves a supporting function;

[0009] The second support bracket is located next to the first support bracket;

[0010] The feeding conveyor belt, located above the first support bracket, can transport the battery copper bars.

[0011] The positioning component, connected to the feeding conveyor belt, prevents the battery copper bars from shifting during movement;

[0012] Two locking components are positioned above the second support bracket. Each locking component includes a locking pin that can extend into the pin hole at the bent end of the battery copper bar to position the battery copper bar.

[0013] Two clamping mechanisms are respectively located below the two locking pins to ensure that the locking pins do not move horizontally.

[0014] The punching mechanism includes four punching and pressing machines. The four punching and pressing machines are set at one end of the conveying direction of the feeding conveyor belt. The four punching and pressing machines are grouped in pairs. The two punching and pressing machines in each group can perform one punching action on the battery copper bar.

The several positioning pins are fixedly connected to the corresponding positioning baffles respectively. One end of the several positioning springs is connected to the several positioning slides, and the other end is connected to the corresponding positioning baffle.

[0019] Furthermore, the punching mechanism also includes two push cylinders, two positioning brackets, and two positioning modules. The two positioning modules are formed with limit holes.

[0020] Furthermore, the locking assembly also includes a limit pin, a limit chuck, a bearing, a positioning key shaft, and two anti-disengagement washers. The limit pin is located beside and abuts against the locking pin shaft. The limit chuck is fixedly connected to the lower end of the locking pin shaft. The bearing is located inside the limit chuck. The two anti-disengagement washers are located at both ends of the bearing. The positioning key shaft is fixedly connected to the two anti-disengagement washers respectively.

[0021] Furthermore, the locking assembly also includes a movable chuck, a positioning top cover, a locking spring, a positioning base, two reinforcing pins, and four limiting baffles. The movable chuck is fixedly connected to the lower end of the positioning key shaft. Anti-disengagement flanges are formed around the movable chuck. The four limiting baffles are connected to each other and arranged around the movable chuck. Anti-disengagement grooves are formed on the four limiting baffles. The anti-disengagement flanges and anti-disengagement grooves are slidably connected. The positioning top cover is fixedly connected to the upper end of the four limiting baffles. The positioning top cover is also rotatably connected to the locking pins. The positioning base is fixedly connected to the lower end of the four limiting baffles. The upper ends of the two reinforcing pins are slidably connected to the movable chuck, and the lower ends are fixedly connected to the positioning base. The upper end of the locking spring is fixedly connected to the movable chuck, and the other end is fixedly connected to the positioning base.

[0022] Furthermore, the locking pin has an annular limiting groove formed on it, and the upper end of the locking pin has a limiting slope formed on it. The annular limiting groove abuts against the limiting pin.

[0023] Furthermore, the clamping mechanism includes a positioning gripper, a movable gripper, an adjusting wheel, a movable screw, a positioning support, and two sliding pins. The second support bracket has two mounting holes. A limiting baffle is slidably connected to the mounting holes.

[0024] The beneficial effects of this invention compared to the prior art are:

[0025] Firstly, the staggered arrangement of the punched battery copper bars in this device maximizes the use of the space of the pre-formed battery copper bars, which helps to save raw materials.

[0026] Secondly, this device uses a locking pin with a formed annular limiting groove to limit the bent end of the battery copper bar, preventing the battery copper bar from moving during the secondary punching process. It eliminates the need for a telescopic cylinder to limit the locking pin, thus simplifying the device structure.

[0027] Thirdly, the locking pin in this device can automatically position the battery copper bar by abutting against it and by being pressed down by the punching machine, thus avoiding damage to the telescopic cylinder caused by frequent contact between the output end of the telescopic cylinder and the output end of the punching machine.

[0038] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0039] refer to Figures 1 to 8 A punching die for a battery copper bar, comprising:

[0040] The first support bracket 2 serves a supporting function;

[0041] The second support bracket 3 is located beside the first support bracket 2;

[0042] The feeding conveyor belt 1 is set above the first support bracket 2 and can transport the battery copper bars.

[0043] Positioning component 5, connected to feeding conveyor belt 1, can prevent the battery copper bar from shifting during movement;

[0044] Two locking components 15 are positioned above the second support bracket 3. Each locking component 15 includes a locking pin 16, which can extend into the pin hole at the bent end of the battery copper bar to position the battery copper bar.

[0045] Two clamping mechanisms 32 are respectively located below the two locking pins 16, which can ensure that the locking pins 16 will not move horizontally;

[0046] The punching mechanism 39 includes four punching and pressing machines 40. The four punching and pressing machines 40 are set at one end of the conveying direction of the feeding conveyor belt 1. The four punching and pressing machines 40 are in pairs. The two punching and pressing machines 40 in each pair can perform a punching action on the battery copper bar.

[0047] Two mobile conveyor belts 45 are symmetrically arranged on the sides of the two locking pins 16, which can transport away the punched battery copper bars.

[0048] The guide plate 46 is set at the end of the two moving conveyors 45 away from the feeding conveyor 1. The guide plate 46 can guide the punched battery copper bars to slide down.

[0049] When the device is running, the feeding conveyor belt 1 starts to transport the battery copper bar preform. When the battery copper bar moves to the lower end of the first set of punching and molding machines 40, the first set of punching and molding machines 40 can perform the first punching of the battery copper bar preform. During this process, the bent end of the battery copper bar will be punched and shaped. Then the feeding conveyor belt 1 continues to run, and the battery copper bar preform continues to move. The punched part will move to the lower end of the second set of punching and molding machines 40. The second set of punching and molding machines 40 will perform the second punching of the battery copper bar. At this time, when the locking pin 16 contacts the bent end of the battery copper bar, it can first move downward and rotate 180° and then return upward. At this time, the locking pin 16 can position the pin hole of the bent end of the battery copper bar. During the second punching process, the locking pin 16 will move downward and rotate 180° and then return upward. At this time, the battery copper bar completes the punching work and can be transported by the moving conveyor belt 45 and collected after being guided by the guide plate 46.

[0050] To prevent wrinkles from forming on the precast copper bars of the battery during movement, the following features are specifically designed:

[0051] The positioning assembly 5 includes two support brackets 7 and several upper positioning rollers 6. The two support brackets 7 are fixedly connected to both sides of the feeding conveyor belt 1, and the several upper positioning rollers 6 are equally spaced along the two support brackets 7. The two ends of the several upper positioning rollers 6 are rotatably connected to the two support brackets 7, and the several upper positioning rollers 6 abut against the battery copper bar preforms on the feeding conveyor belt 1. During the movement of the battery copper bar preforms, the several upper positioning rollers 6 can apply a clamping force to the battery copper bar preforms from top to bottom to prevent wrinkles from forming on the battery copper bar preforms.

[0052] To prevent the precast copper bars of the battery from shifting horizontally during movement, the following features are specifically designed:

[0053] The positioning assembly 5 also includes two positioning support plates 8, a number of positioning rollers 9, a number of positioning pins 10, a number of positioning pin shafts 12, a number of positioning slides 11, a number of positioning springs 13, and a number of positioning baffles 14. The two positioning support plates 8 are fixedly connected to the two support brackets 7 respectively. The number of positioning rollers 9 are equally spaced at the lower ends of the two positioning support plates 8. The number of positioning rollers 9 abut against the two ends of the battery copper bar precast strip respectively. The number of positioning pin shafts 12 are rotatably connected to the number of positioning rollers 9 respectively. The number of positioning slides 11 are rotatably connected to the upper ends of the number of positioning pin shafts 12 respectively. The two ends of the number of positioning slides 11 are slidably connected to the number of positioning pins 10 respectively. The number of positioning baffles 14 are respectively located at the ends of the number of positioning slides 11 away from the battery copper bar. The number of positioning pins 10 are fixedly connected to the corresponding positioning baffles 14 respectively. One end of the number of positioning springs 13 is connected to the number of positioning slides 11, and the other end is connected to the corresponding positioning baffles 14. As the battery copper bar preform moves, several positioning rollers 9 will abut against both sides of the battery copper bar preform, and several positioning springs 13 can ensure that the positioning rollers 9 are pressed against the battery copper bar preform, preventing the battery copper bar preform from moving horizontally during the movement.

[0054] To ensure that the punched battery copper bars can be transported away by the moving conveyor belt 45, the following features are specifically designed:

[0055] The punching mechanism 39 also includes two pushing cylinders 41, two positioning brackets 42, and two positioning modules 43. The two positioning modules 43 have limiting holes 44 formed on them. The two positioning brackets 42 are symmetrically arranged on the upper end of the second support bracket 3. The two pushing cylinders 41 are fixedly connected to the two positioning brackets 42 respectively, and the two positioning modules 43 are fixedly connected to the output ends of the two pushing cylinders 41 respectively. The limiting holes 44 can slide with the locking pin 16. After the battery copper bar is punched, the two pushing cylinders 41 are activated to push the two positioning modules 43 to move. The two positioning modules 43 not only provide support for the battery copper bar during punching but also lift the battery copper bar after punching and move it to the upper end of the corresponding moving conveyor belt 45, so that the punched battery copper bar is conveyed away by the moving conveyor belt 45.

[0056] To prevent the locking pin 16 from shifting during rotation, the following features are specifically designed:

[0057] The locking assembly 15 also includes a limiting pin 19, a limiting chuck 21, a bearing 22, a locating key shaft 23, and two anti-detachment washers 20. The limiting pin 19 is located beside and abuts against the locking pin 16. The limiting chuck 21 is fixedly connected to the lower end of the locking pin 16. The bearing 22 is located inside the limiting chuck 21. The two anti-detachment washers 20 are respectively located at both ends of the bearing 22. The locating key shaft 23 is fixedly connected to the two anti-detachment washers 20 respectively. When the locking pin 16 rotates, the limiting pin 19 abuts against the locking pin 16, allowing the locking pin 16 to rotate. To limit the rotation of the locking pin 16, the rotation of the locking pin 16 will drive the limiting chuck 21 connected to it to rotate. When the limiting chuck 21 rotates, it can be limited by the bearing 22 to prevent the locking pin 16 from moving during rotation.

[0058] To ensure that the locking pin 16 can reciprocate vertically, the following features are specifically designed:

[0059] The locking assembly 15 also includes a movable chuck 24, a positioning top cover 28, a locking spring 29, a positioning base 31, two reinforcing pins 30, and four limiting baffles 26. The movable chuck 24 is fixedly connected to the lower end of the positioning key shaft 23. Anti-detachment flanges 25 are formed around the movable chuck 24. The four limiting baffles 26 are connected to each other and arranged around the movable chuck 24. Anti-detachment grooves 27 are formed on the four limiting baffles 26. The anti-detachment flanges 25 and anti-detachment grooves 27 are slidably connected. The positioning top cover 28 is fixedly connected to the upper end of the four limiting baffles 26. The positioning top cover 28 is also rotatably connected to the locking pins 16. The positioning base 31 is fixedly connected to the lower end of the four limiting baffles 26. The upper ends of the two reinforcing pins 30 are slidably connected to the movable chuck 24, and the lower ends are fixedly connected to the positioning base 31. The upper end of the locking spring 29 is fixedly connected to the movable chuck 24, and the other end is fixedly connected to the positioning base 31. When the locking pin 16 moves downward, the locking spring 29 can be compressed. The compressed locking spring 29 can push the locking pin 16 to move upward. During the movement, the movable chuck 24 can be connected through the anti-disengagement flange 25 and the anti-disengagement groove 27 to ensure that the locking pin 16 can move downward and reset upward.

[0060] In order to enable the locking pin 16 to rotate during the downward stroke, the following features are specifically designed:

[0061] The locking pin 16 has an annular limiting groove 17 formed on it, and a limiting inclined surface 18 formed at the upper end of the locking pin 16. The annular limiting groove 17 abuts against the limiting short pin 19. When the locking pin 16 moves, the annular limiting groove 17 abuts against the limiting short pin 19, meaning that the locking pin 16 can rotate 180° during the movement, and the limiting short pin 19 can lock the limiting groove 17 at its bottom after rotation, allowing the locking pin 16 to rotate a second time after being pressed again. The limiting inclined surface 18 ensures that when the limiting short pin 19 contacts the battery copper bar, the battery copper bar abuts against the limiting inclined surface 18, thereby pushing the limiting short pin 19 downward.

[0062] To prevent the limit baffle 26 from shifting and affecting the positioning of the locking pin 16, the following features are specifically provided:

[0063] The clamping mechanism 32 includes a positioning gripper 33, a movable gripper 34, an adjusting wheel 38, a movable screw 36, a positioning support 37, and two sliding pins 35. The second support bracket 3 has two mounting holes 4. The limiting baffle 26 is slidably connected to the mounting holes 4. The positioning gripper 33 is located on one side of the mounting holes 4, and the movable gripper 34 is located on the other side of the mounting holes 4. One end of the movable screw 36 is rotatably connected to the movable gripper 34, and the other end is threadedly connected to the positioning support 37. The positioning support 37 is fixedly connected to the second support bracket 3. The two sliding pins 35 are symmetrically arranged on both sides of the movable screw 36. One end of the two sliding pins 35 is fixedly connected to the movable gripper 34, and the other end is slidably connected to the positioning support 37. The adjusting wheel 38 is fixedly connected to the end of the movable screw 36 that extends out of the positioning support 37. To prevent the limit baffle 26 from shifting after being inserted into the mounting hole 4, the operator can turn the adjusting wheel 38. The rotation of the adjusting wheel 38 will push the movable claw 34 closer to the positioning claw 33 through the movable screw 36. Finally, the movable claw 34 will press against the limit baffle 26, so that the limit baffle 26 in the mounting hole 4 will not shift, thus completing the positioning of the locking pin 16.

[0064] The working principle of this device is as follows: when the feeding conveyor belt 1 is started, it can transport the battery copper bar preforms. During this process, several upper positioning rollers 6 can press the battery copper bar preforms downward and position them, while several positioning rollers 9 can prevent the battery copper bar preforms from moving horizontally.

[0065] When the battery copper bar moves to the lower end of the first set of punching and molding machines 40, the first set of punching and molding machines 40 can perform the first punching of the battery copper bar preform. During this process, the bent end of the battery copper bar will be punched and shaped. Then the feeding conveyor belt 1 continues to run, and the battery copper bar preform will continue to move. The punched part will move to the lower end of the second set of punching and molding machines 40. The second set of punching and molding machines 40 will perform the second punching of the battery copper bar. At this time, when the locking pin 16 contacts the bent end of the battery copper bar, the battery copper bar abuts against the limiting inclined surface 18 of the locking pin 16, which can push the locking pin 16 first. After moving downwards and rotating 180°, the battery copper bar returns to its original position. During this process, the limiting pin 19 abuts against the limiting groove 17, which enables the locking pin 16 to rotate and return to its original position. At this time, the locking pin 16 can position the pin hole at the bent end of the battery copper bar. During the second punching process, the locking pin 16 will move downwards and rotate 180° before returning to its original position. At this time, the battery copper bar completes the punching process. Then, the two pushing cylinders 41 are activated to push the punched battery copper bar onto the corresponding moving conveyor belt 45. Finally, the battery copper bar can be transported by the moving conveyor belt 45 and collected after being guided by the guide plate 46.

[0066] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
