Description

Technical Field

[0001] The present invention belongs to the technical field of copper bar bending, and specifically relates to a copper bar bending device for automotive batteries and a usage method thereof. Background Art

[0002] The battery of an electric vehicle is an energy storage device capable of charging and discharging, and is also a mobile power source. It is widely used in electric vehicles. To meet the power requirements of voltage and current, battery modules are usually connected in series or in parallel, and the maximum current can reach several hundred amperes. The connection of battery modules generally uses copper bars or copper wires, and connectors are generally crimped at both ends of the copper bars or copper wires. Among them, the copper bar connection structure is a hard connection.

[0003] In the prior art, when producing copper bars for automotive batteries, bending treatment is required. Existing bending devices generally do not have an adjustment mechanism. When bending copper bars of different thicknesses, the limit mechanism needs to be replaced to continue the bending work. This operation is rather cumbersome, not flexible enough during use, and most bending mechanisms cannot perform continuous bending work on copper bars. After bending a copper bar once, the position of the copper bar needs to be adjusted manually to continue the bending work, resulting in low efficiency.

[0004] Therefore, we propose a copper bar bending device for automotive batteries to solve the problems encountered above. Summary of the Invention

[0009] As a preferred embodiment of the present invention, an activity groove is formed inside the right-side mounting seat. The first spur gear and the first toothed ring are both arranged inside the activity groove.

[0010] As a preferred embodiment of the present invention, the second bending mechanism includes a third motor, and the third motor is disposed on the upper surface of the left side of the lower mounting base. The power output end of the third motor is drivingly connected to a second straight gear. The right side of the second straight gear is meshingly connected to a second toothed ring.

The front end of the lower surface of the upper mounting block is provided with a second lateral limiting block. The second lateral limiting block is located in front of the first lateral limiting block. When the second lateral limiting block and the two first lateral limiting blocks are in the same horizontal plane, the distance between any two of them is slightly larger than the width of the copper bar.

[0012] As a preferred embodiment of the present invention, the third bending mechanism includes a fixing block. The fixing block is disposed at the right front of the hollow rotating column. The upper end of the fixing block is provided with a vertical rod. The circumferential surface of the upper end of the vertical rod is provided with a hollow sleeve. The circumferential surface of the middle part of the hollow sleeve is slidably sleeved with a lower pressing plate. A copper bar pushing space is formed between the lower pressing plate and the inner bottom wall of the hollow sleeve. The upper surface of the lower pressing plate is provided with four lifting sleeves. The upper ends of the four lifting sleeves penetrate through the upper end of the hollow sleeve. The upper surface of the hollow sleeve is provided with four fixing sleeves. The upper ends of the four lifting sleeves are respectively movably installed inside the four fixing sleeves through pressing springs.

[0013] As a preferred embodiment of the present invention, the front end of the left side of the lower pressing plate is provided with an arc-shaped pushing block. The inner side of the upper end of the arc-shaped pushing block does not contact the side wall of the hollow sleeve.

The depth of the first lifting groove is the same as the depth of the second lifting groove.

[0015] As a preferred embodiment of the present invention, a method for using a copper bar bending device specifically includes the following steps:

[0016] Step 1: Limit the front end of the copper bar through the preliminary limiting mechanism, and then the pushing device pushes the copper bar horizontally forward. When the copper bar is pushed to the left side of the secondary limiting mechanism, the moving mechanism on the right side works to drive the secondary limiting mechanism to move horizontally to the left, so that the two longitudinal limiting blocks in the secondary limiting mechanism move to the upper and lower sides of the copper bar respectively to limit it. Then, the first bending mechanism works to drive the bending rod to rotate axially. When the two bending rods rotate upward, the copper bar can be bent upward, and when the two bending rods rotate downward, the copper bar can be bent downward;

[0017] Step 2: When the copper bar needs to be bent horizontally, the secondary limiting mechanism is reset to the right through the right-side moving mechanism to avoid collision between the secondary limiting mechanism when the second bending mechanism moves upward. Then, first start the lower moving mechanism to drive the second bending mechanism to move upward, so that the copper bar is located on the upper surface of the second fixed column and in the middle of the two first horizontal limiting blocks. Then, the upper moving mechanism drives the upper mounting block and the second horizontal limiting block to move downward, so that the rear side of the lower surface of the upper mounting block abuts against the upper surfaces of the two first horizontal limiting blocks, and at the same time, the lower surface of the second horizontal limiting block abuts against the upper surface of the copper bar, and the two first horizontal limiting blocks and one second horizontal limiting block limit the copper bar;

[0018] Step 3: Start the second bending mechanism to drive the third bending mechanism to rotate axially. When the third bending mechanism rotates to the left, the copper bar can be bent to the left. Then, the second bending mechanism drives the third bending mechanism to rotate in the reverse direction, and the copper bar can be bent to the right to perform the horizontal bending work on the copper bar;

[0019] Step 4: After bending, the left-side moving mechanism drives the shearing machine to move to the right, so that the shearing machine cuts the copper bar, and the bent copper bar in the front is separated. The staff or the robotic arm set in the front can take away the bent copper bar, and then the copper bar bending work can continue.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) By setting the first bending mechanism, the second bending mechanism and the third bending mechanism, the copper bar can be bent horizontally and longitudinally, and can be carried out continuously during bending without stopping to adjust the copper bar, with simple operation and high working efficiency;

[0022] (2) By setting the preliminary limiting mechanism and the secondary limiting structure, copper bars with different thicknesses can be limited within a certain range, so as to improve the applicable range of the equipment without affecting the bending work, and the use is more flexible.

Detailed implementation manners

[0031] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1:

[0033] Please refer to Figure 1 -Figure 6 As shown in the figure, a copper bar bending device for automobile batteries includes a mounting plate 1. A preliminary limiting mechanism 2 is arranged in the middle of the mounting plate 1. The preliminary limiting mechanism 2 includes a mounting frame 201, and the mounting frame 201 is fixedly installed inside the mounting plate 1. A rotating rod 202 is rotatably installed inside the front end on the right side of the mounting frame 201. A first bevel gear 203 is arranged at the rear end of the rotating rod 202. The rear end of the first bevel gear 203 is meshed with a second bevel gear 204. A first threaded rod 205 is arranged in the middle of the second bevel gear 204. Lifting blocks 206 are threadedly connected to the circumferential surfaces on the upper and lower sides of the first threaded rod 205. The thread directions on the upper and lower sides of the first threaded rod 205 are opposite. When the first threaded rod 205 rotates, the two lifting blocks 206 can approach or move away from each other. U-shaped lifting frames 207 are arranged on the left sides of the two lifting blocks 206. Limiting rollers 208 are rotatably installed inside the two U-shaped lifting frames 207. Through the arrangement of the upper and lower two groups of U-shaped lifting frames 207 and limiting rollers 208, the distance between the two groups of U-shaped lifting frames 207 can be adjusted, and then within a certain range, copper bars of different thicknesses can be limited and transferred, improving the applicable range of the bending device;

[0034] Four groups of moving mechanisms 3 are arranged in a circumferential array on the surface of the mounting plate 1. The moving mechanism 3 includes a track plate 301, and the track plate 301 is arranged on the surface of the mounting plate 1. A first motor 302 is arranged on one side of the track plate 301. The power output end of the first motor 302 is drivingly connected to a second threaded rod 303. A moving block 304 is threadedly connected to the circumferential surface of the second threaded rod 303. A mounting seat 305 is arranged at the front end of the moving block 304. The right end of the first fixed column 501 is fixedly installed inside the left side of the right mounting seat 305. The moving structures of the four groups of moving mechanisms 3 are generally the same. By the operation of the first motor 302 to drive the second threaded rod 303 to rotate, the left and right moving blocks 304 and mounting seats 305 move horizontally, and the upper and lower moving blocks 304 and mounting seats 305 move vertically;

[0035] At the front end of the right moving mechanism 3, there is a first bending mechanism 4 and a secondary limiting mechanism 5. The first bending mechanism 4 includes a second motor 401, and the second motor 401 is arranged on the right outer wall of the right mounting seat 305. The power output end of the second motor 401 is drivingly connected to a rotating shaft 402. At the left end of the rotating shaft 402, there is a first spur gear 403. The lower end of the first spur gear 403 is meshed with a first toothed ring 404. Inside the first toothed ring 404, there is an annular rotating plate 405. Inside the right mounting seat 305, there is an activity groove 407. The first spur gear 403 and the first toothed ring 404 are both arranged inside the activity groove 407. The setting of the activity groove 407 provides an activity space for the first spur gear 403 and the first toothed ring 404, enabling the first spur gear 403 and the first toothed ring 404 to rotate smoothly inside the mounting seat 305. The left end of the annular rotating plate 405 penetrates through the mounting seat 305 and is connected to a hollow rotating block 406. On the upper and lower sides of the front end of the left side of the annular rotating plate 405, there are both bending rods 8. The secondary limiting mechanism 5 includes a first fixing column 501. The left end of the first fixing column 501 is inserted into the inside of the hollow rotating block 406. Inside the first fixing column 501, there is a third threaded rod 502 rotatably installed. On the circumferential surfaces of the upper and lower sides of the third threaded rod 502, there are both lifting plates 503 threadedly connected. At the left end of both lifting plates 503, there are longitudinal limiting blocks 504. The longitudinal limiting blocks 504 are located on the left side of the hollow rotating block 406. The distance between the two longitudinal limiting blocks 504 is the same as the distance between the two limiting rollers 208. Among them, the thread helix directions on the upper and lower surfaces of the third threaded rod 502 are opposite, so that when the third threaded rod 502 rotates, the two lifting plates 503 can approach or move away from each other, thereby changing the distance between the two longitudinal limiting blocks 504, and further limiting copper bars of different thicknesses;

[0036] It should be noted that the setting of the two bending rods 8 can drive the bending rods 8 to rotate axially when the hollow rotating block 406 rotates after the two longitudinal limiting blocks 504 limit the copper bar. The bending rods 8 can perform bending work on the copper bar, enabling the copper bar to be bent upward or downward by a certain angle. When the hollow rotating block 406 drives the bending rod 8 to rotate upward by 90 degrees, a right angle upward can be bent out of the copper bar. At this time, after the upward bending is completed, the hollow rotating block 406 will drive the bending rod 8 to reset first, and then wait for the console to transmit a signal of upward bending, downward bending, or no need for longitudinal bending work, so as to perform continuous longitudinal bending or proceed to the next step;

[0037] At the front end of the lower end moving mechanism 3, there are a second bending mechanism 6 and a third bending mechanism 7. The second bending mechanism 6 includes a third motor 601, and the third motor 601 is arranged on the upper surface of the left side of the lower mounting seat 305. The power output end of the third motor 601 is drivingly connected with a second spur gear 602. The right side of the second spur gear 602 is meshed and connected with a second toothed ring 603. The inner side of the second toothed ring 603 is provided with a hollow rotating column 604, and the lower end of the hollow rotating column 604 is rotatably installed inside the lower mounting seat 305. A second fixing column 605 is inserted in the middle of the hollow rotating column 604, and the lower end of the second fixing column 605 is fixedly installed on the upper surface of the lower mounting seat 305. At the left and right ends of the rear side of the upper surface of the second fixing column 605, there are first horizontal limit blocks 606. The setting of the two first horizontal limit blocks 606 can limit the left and right sides of the copper row when the copper row is located on the upper surface of the second fixing column 605, avoiding the deviation of the copper row during horizontal bending and affecting the bending effect.

[0038] The third bending mechanism 7 includes a fixing block 701. The fixing block 701 is arranged at the right front of the hollow rotating column 604. The upper end of the fixing block 701 is provided with a vertical rod 702. The circumferential surface of the upper end of the vertical rod 702 is provided with a hollow sleeve 703. The circumferential surface of the middle part of the hollow sleeve 703 is slidably sleeved with a lower pressing plate 704. The space between the lower pressing plate 704 and the inner bottom wall of the hollow sleeve 703 is the copper row pushing space. Because, if it is set as a cylinder, it is easy for the copper row to slip when contacting the outer surface of the cylinder during horizontal bending, resulting in the deviation of the angle during bending and producing defective products. Therefore, the set copper row pushing space can make the copper row stably enter the space between the lower pressing plate 704 and the hollow sleeve 703 when the hollow sleeve 703 rotates towards the copper row, so that the copper row will not slide up and down during bending and affect the bending effect. The upper surface of the lower pressing plate 704 is provided with four lifting sleeves 706. The upper ends of the four lifting sleeves 706 penetrate through the upper end of the hollow sleeve 703. The upper surface of the hollow sleeve 703 is provided with four fixing sleeves 707. The upper ends of the four lifting sleeves 706 are respectively movably installed inside the four fixing sleeves 707 through compression springs 705. The setting of the compression springs 705 can apply a downward force to the lower pressing plate 704, so that when the copper row enters the copper row pushing space, the lower pressing plate 704 will apply a resisting force to the copper row, thereby improving the stability of the copper row and further improving the bending quality. The front end of the left side of the lower pressing plate 704 is provided with an arc-shaped pushing block 9. The inner side of the upper end of the arc-shaped pushing block 9 does not contact the side wall of the hollow sleeve 703. The setting of the arc-shaped pushing block 9 can make the arc-shaped pushing block 9 contact the copper row first when the hollow sleeve 703 rotates towards the copper row. If the thickness of the copper row is greater than the copper row pushing space at this time, the copper row will push the arc-shaped pushing block 9 upward, so that the arc-shaped pushing block 9 drives the lower pressing plate 704 to move upward, and then the copper row can stably enter the copper row pushing space.

[0039] It should be noted that by Figure 1 the position of the fixed block 701 in [reference], the hollow rotating column 604 will only drive the fixed block 701 to rotate clockwise, thereby bending the copper bar to the left. After bending the left side of the copper bar, it is necessary to first move the third bending mechanism 7 downward to below the copper bar, so that the copper bar moves forward a certain distance, and then the third bending mechanism 7 moves upward. Then the third bending mechanism 7 rotates and resets, which can bend the copper bar to the right, or after moving the third bending mechanism 7 to below the copper bar, reset the third bending mechanism 7 and then move it upward. When the third bending mechanism 7 works, it will still bend the copper bar to the left. Similarly, only need to rotate the fixed block 701 to the front left of the hollow rotating column 604 first. At this time, when the third bending mechanism 7 works, it will first bend the copper bar to the right. The operation is flexible and changeable, and the practicability is high.

[0040] At the lower end of the upper mounting seat 305, there is an upper mounting block 10. At the front end of the lower surface of the upper mounting block 10, there is a transverse limiting block two 11. The transverse limiting block two 11 is located in front of the transverse limiting block one 606. When the transverse limiting block two 11 and the two transverse limiting blocks one 606 are in the same horizontal plane, the distance between each pair is slightly larger than the width of the copper bar. The two transverse limiting blocks one 606 can limit the left and right sides of the copper bar, and the transverse limiting block two 11 can limit the upper side of the copper bar, so that the copper bar will not shift during horizontal bending, improving the bending quality. And the space reserved between the three provides space for the copper bar to bend, enabling the copper bar to smoothly carry out the bending work. Among them, the height of the transverse limiting block one 606 and the transverse limiting block two 11 is greater than the maximum thickness of the copper bar that the equipment can clamp, so that copper bars of different thicknesses can be located inside the transverse limiting block one 606, avoiding the upper end of the copper bar protruding from the transverse limiting block one 606 and affecting the bending effect;

[0041] Lifting grooves one 209 are respectively opened inside the upper and lower sides of the installation frame 201. Two lifting blocks 206 are respectively arranged inside the two lifting grooves one 209. Lifting grooves two 505 are respectively opened inside the upper and lower sides of the fixed column one 501. Two lifting plates 503 are respectively arranged inside the two lifting grooves two 505. The thickness of the lifting block 206 is the same as the thickness of the lifting plate 503. The depth of the lifting groove one 209 is the same as the depth of the lifting groove two 505. The same depth makes the maximum distance and the minimum distance between the two lifting blocks 206 and the two lifting plates 503 the same, and then can limit the copper bars within the same range.

[0042] Embodiment 2:

[0043] Please refer to Figure 1 - Figure 6 shown. The present invention also discloses a method for using a copper bar bending device, which specifically includes the following steps;

[0044] Step 1: First, move the front end of the copper bar forward from between the two limiting roller cylinders 208. Then, rotate the rotating rod 202. The rotating rod 202 drives the first threaded rod 205 to rotate through the first bevel gear 203 and the second bevel gear 204, so that the two lifting blocks 206 drive the two groups of U-shaped lifting frames 207 and the two groups of limiting roller cylinders 208 to approach the copper bar, thereby limiting the front end of the copper bar. Then, the pushing device arranged at the rear side of the mounting plate 1 pushes the copper bar horizontally forward. The pushing device is an existing device, so it will not be elaborated here. When the copper bar is pushed to the left side of the secondary limiting mechanism 5, the motor 302 on the right side works to drive the second threaded rod 303 to rotate, so that the moving block 304 drives the mounting seat 305 to move leftward, so that the two longitudinal limiting blocks 504 respectively move to the upper and lower sides of the copper bar to limit the copper bar. After that, the motor 401 works to drive the rotating shaft 402 and the first spur gear 403 to rotate. The rotation of the first spur gear 403 drives the first toothed ring 404, the annular rotating plate 405 and the hollow rotating block 406 to rotate. The rotation of the hollow rotating block 406 drives the bending rod 8 to axially rotate, so that the bending rod 8 performs longitudinal bending work on the copper bar;

[0045] Step 2: After the longitudinal bending is completed, the secondary limiting mechanism 5 is reset to the right through the moving mechanism 3 on the right side to prevent the secondary limiting mechanism 5 from being collided when the second bending mechanism 6 moves upward. Then, start the moving mechanism 3 below to drive the mounting seat 305 below to move upward. The upward movement of the mounting seat 305 drives the second bending mechanism 6 and the third bending mechanism 7 to move upward, so that the copper bar is located on the upper surface of the second fixed column 605 and is simultaneously in the middle of the two first transverse limiting blocks 606. Then, the moving mechanism 3 above drives the upper mounting block 10 and the second transverse limiting block 11 to move downward, so that the rear side of the lower surface of the upper mounting block 10 abuts against the upper surfaces of the two first transverse limiting blocks 606, and at the same time, the lower surface of the second transverse limiting block 11 abuts against the upper surface of the copper bar. The two first transverse limiting blocks 606 and one second transverse limiting block 11 limit the copper bar;

[0046] Step 3: Start the motor 601. The motor 601 drives the second spur gear 602 to rotate. The rotation of the second spur gear 602 drives the second toothed ring 603 and the hollow rotating column 604 to rotate. The rotation of the hollow rotating column 604 will drive the entire third bending mechanism 7 to axially rotate. When the third bending mechanism 7 rotates, the copper bar will first be clamped in the space between the inner bottom of the hollow sleeve 703 and the lower pressing plate 704. Then, the third bending mechanism 7 continues to rotate, and the copper bar can be transversely bent. After the third bending mechanism 7 transversely bends the copper bar, it is necessary to first move the second bending mechanism 6 and the third bending mechanism 7 downward through the moving mechanism 3 so that the uppermost ends of the second bending mechanism 6 and the third bending mechanism 7 are all located below the copper bar before the copper bar can be pushed forward;

[0047] Step 4: After the bending is completed, the left moving mechanism 3 drives the shearing machine to move to the right. The shearing machine is an existing device and will not be elaborated here. The shearing machine cuts the copper bar, causing the bent copper bar in the front to break away. Workers or the robotic arm set in the front can take away the bent copper bar, and then the copper bar bending work can continue.

10. A method for using a copper bar bending device, characterized in that, Applied to a copper bar bending device for an automotive battery according to any one of the above claims 1-9, it specifically includes the following steps: Step 1: Limit the front end of the copper bar through the preliminary limiting mechanism (2), and then the pushing device pushes the copper bar horizontally forward. When the copper bar is pushed to the left side of the secondary limiting mechanism (5), the moving mechanism (3) on the right works to drive the secondary limiting mechanism (5) to move horizontally to the left, so that the two longitudinal limiting blocks (504) inside the secondary limiting mechanism (5) respectively move to the upper and lower sides of the copper bar to limit it. Then the bending mechanism one (4) works to drive the bending rod (8) to rotate axially. When the two bending rods (8) rotate upward, the copper bar can be bent upward. When the two bending rods (8) rotate downward, the copper bar can be bent downward; Step 2: When the copper bar needs to be bent horizontally, the secondary limiting mechanism (5) is reset to the right through the right moving mechanism (3) to prevent the bending mechanism II (6) from colliding with the secondary limiting mechanism (5) when moving upward. Then, first start the lower moving mechanism (3) to drive the bending mechanism II (6) to move upward, so that the copper bar is located on the upper surface of the fixed column II (605) and is also between the two horizontal limiting blocks I (606). Then, the upper moving mechanism (3) drives the upper mounting block (10) and the horizontal limiting block II (11) to move downward, so that the rear side of the lower surface of the upper mounting block (10) abuts against the upper surfaces of the two horizontal limiting blocks I (606), and at the same time, the lower surface of the horizontal limiting block II (11) abuts against the upper surface of the copper bar, and the two horizontal limiting blocks I (606) and one horizontal limiting block II (11) limit the copper bar; Step 3: Start the bending mechanism II (6) to drive the bending mechanism III (7) to rotate axially. When the bending mechanism III (7) rotates to the left, the copper bar can be bent to the left. Then, the bending mechanism II (6) drives the bending mechanism III (7) to rotate in the reverse direction, and the copper bar can be bent to the right to complete the horizontal bending work of the copper bar; Step 4: After bending, the left moving mechanism (3) drives the shearing machine to move to the right, so that the shearing machine cuts the copper bar, and the bent copper bar in the front is separated. The staff or the robotic arm set in the front can take away the bent copper bar, and then the copper bar bending work can continue.
