Description

Technical Field

[0001] This invention relates to the field of busbar shearing equipment, and more specifically, to a shearing device for the production and processing of busbars. Background Technology

[0002] Busbar trunking is a core power transmission carrier in modern building and industrial power distribution systems. It boasts advantages such as high current carrying capacity, excellent insulation, neat wiring, and high safety and reliability, and is widely used in power transmission scenarios such as large supermarkets, industrial plants, and rail transit. Currently, most mainstream busbar trunking on the market uses a hollow trough structure made of aluminum alloy. After extrusion and roll forming, it needs to be cut to a fixed length according to the on-site construction dimensions. The cutting process is a key step that determines the dimensional accuracy, assembly performance, and safety of the finished busbar trunking. Correspondingly, the cutting equipment used in busbar trunking production is mainly used for the automated cutting of long, hollow busbar trunking profiles and is the core processing equipment for large-scale busbar trunking production.

[0003] The prior art publication number CN215698364U provides a shearing device for producing aluminum alloy busbars with controllable length. The device indirectly drives the placement plate to rotate by the extension and retraction of a second electric telescopic rod, so that the aluminum alloy busbar can be placed horizontally at an angle, thereby shearing the end face of the aluminum alloy busbar into a bevel for installation. While the aforementioned existing technical solutions can achieve the relevant beneficial effects through their structure, the workpiece is continuously subjected to the vertical cutting pressure applied by the cutting disc during the cutting process. Under the cutting load, the stress area of ​​the profile undergoes elastic deformation and elastic yielding along the direction of force, making the shearing end face of the busbar trunking extremely prone to deformation. This results in the following defects in the actual use of the aforementioned existing busbar trunking production shearing equipment: When the cutting disc presses down and cuts into the aluminum alloy busbar, the equipment generates a large impact shear stress. The aluminum alloy busbar has a groove structure and is hollow and unsupported inside. The concentrated stress generated during the shearing process can easily cause plastic deformation of the busbar wall. This is especially true for busbars with thin walls, which will undoubtedly increase the scrap rate of the workpiece and the subsequent reprocessing cost.

[0004] In view of this, we propose a shearing device for the production and processing of busbar trunking. Summary of the Invention

[0016] Beneficial effects One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. Through the design of the outer and inner limiting mechanisms, when cutting aluminum alloy busbars, the outer side of the cutting point of the aluminum alloy busbar can be fully supported and limited. When the electric cylinder moves the support downward to cut the aluminum alloy busbar, it effectively avoids the shear stress generated by the cutting disc pressing down into the aluminum alloy busbar. Because the groove in the aluminum alloy busbar has no internal support, the stress cannot be evenly distributed, which leads to plastic deformation of the groove wall, thus improving the yield of aluminum alloy busbar cutting.

[0017] 2. By setting up an auxiliary support mechanism, before cutting the aluminum alloy busbar trough, the support frame is made to fit against the inner top wall of the groove, and the support frame is made to fit against the bottom of the aluminum alloy busbar trough. Then, the electric cylinders of the two sets of auxiliary support mechanisms are controlled to drive the lower plate to move down, so that the contact block fits against the inner bottom wall of the groove. This achieves the effect of supporting the inside of the aluminum alloy busbar trough through the auxiliary support mechanism, improving the stability of the internal support of the aluminum alloy busbar trough, and further avoiding the plastic deformation of the trough wall when cutting the aluminum alloy busbar trough.

[0018] 3. By designing positioning blocks and holes, when cutting aluminum alloy busbars of different widths, the bolts can be removed to eliminate the limiting effect on the positioning blocks, allowing for the disassembly of the fixed base. This enables the replacement of limiting components one and two, ensuring that the width between the support frame and the upper limit plate of limiting component one is the same as the width of the groove. This provides stable support inside the groove of the aluminum alloy busbar when cutting aluminum alloy busbars of different widths, improving the applicability of the equipment. Furthermore, through the design of the threaded sleeve and threaded rod, when cutting aluminum alloy busbars of different widths, rotating the threaded sleeve allows the fixed plate to shift along the telescopic rod, adjusting the position of the two side limiting blocks. This ensures that when the cutting point of the aluminum alloy busbar is below the cutting disc, the two side limiting blocks can limit the side plate portion of the aluminum alloy busbar.

[0019] 4. When it is necessary to perform inclined shearing at the cutting point of the aluminum alloy busbar, control the motor to rotate its output shaft, which drives the mounting block to rotate on the bracket through the bevel gear assembly, thereby driving the cutting disc to rotate. This causes the cutting disc to deflect horizontally, thus achieving an inclined shearing effect at the cutting point of the aluminum alloy busbar without the need for horizontal rotation of the aluminum alloy busbar to cause the end of the aluminum alloy busbar to shift outward, thereby reducing the space required for inclined shearing of the aluminum alloy busbar.

[0020] 5. When performing inclined shearing on the cutting section of the aluminum alloy busbar, the cooperation of two motors, four electromagnets, and two electric sliders ensures that the support frame and the backing frame simultaneously form a parallelogram shape. This allows the cutting disc to press down and make way for the cutting, while simultaneously providing all-around support and limiting effect on the outer side of the cutting section of the aluminum alloy busbar. This effectively prevents plastic deformation of the busbar wall during inclined shearing, thus helping to improve the yield rate of inclined shearing of aluminum alloy busbars.

[0021] 6. When support rod two rotates on support rod one, it causes the contact block in the auxiliary support mechanism to move. Under the magnetic attraction between the electromagnet and the contact block, the electromagnet drives support rod two to rotate around support rod one, so that the support frame and the support frame synchronously form a parallelogram shape. Under the magnetic attraction between the electromagnet and the contact block, the overall shape of the support frame is fixed, thus ensuring the support stability during the cutting and processing of the busbar trunking, while also effectively avoiding damage to the support structure during processing, improving the safety and reliability of equipment operation.

[0022] 7. During the cutting process of aluminum alloy busbar trunking, an industrial camera captures images of the cutting disc in real time. When the cutting disc is damaged, the image is fed back to the main controller. The main controller compares the real-time captured image with the pre-stored standard cutting disc contour template. If the contour difference exceeds a preset threshold, the cutting disc is determined to be damaged. This achieves real-time monitoring of the cutting disc during the cutting process of aluminum alloy busbar trunking, effectively preventing uneven cutting force caused by the damaged cutting disc during continuous cutting of aluminum alloy busbar trunking, which could lead to tearing of the aluminum alloy busbar trunking during the cutting process and the appearance of a large number of sharp burrs and tears on the cut surface. This helps to improve the yield rate of aluminum alloy busbar trunking cutting.

[0023] 8. By setting up suction hoods, when cutting the aluminum alloy busbar, the external negative pressure device is controlled to draw the air outward from the two suction hoods, so that the air on the opposite sides of the two suction hoods flows into the two suction hoods respectively. When the air flows, it carries the dust generated by the cutting of the aluminum alloy busbar to the two suction hoods at the same time, realizing the absorption and cleaning effect of the dust generated by the cutting of the aluminum alloy busbar. This effectively avoids the debris adhering to the industrial camera lens and causing image blurring and obstruction, ensuring that the camera can completely capture the outline image of the cutting disc, thereby reducing the probability of misjudgment and missed detection during image recognition by the main controller, and further helping to improve the yield of aluminum alloy busbar shearing.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or a link; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Reference Figures 1 to 12 This invention provides a shearing device for the production and processing of busbar trunking, comprising: The shearing mechanism 1 includes a support platform 11 and a support frame 12 fixed to the top of the support platform 11. A cutting component 13 is installed on the support frame 12. A clearance hole is provided on the support platform 11 and below the cutting component 13. An aluminum alloy busbar 2 is placed on the support platform 11. A groove 21 is provided on one side of the aluminum alloy busbar 2. The outer limiting mechanism 3 includes a mounting assembly 31 installed on one inner wall of the support frame 12. Side limiting blocks 32 are symmetrically installed at the ends of the mounting assembly 31. Both side limiting blocks 32 are in contact with the side of the aluminum alloy busbar 2 away from the groove 21. The inner limiting mechanism 4 includes a mounting base 41 installed on the inner wall of the other side of the support frame 12. Two sets of telescopic connecting components 42 are installed on the mounting base 41. Limiting component one 43 and limiting component two 44 are installed on the telescopic connecting components 42. When the limiting component one 43 is driven to extend into the groove 21 by the telescopic connecting components 42, the limiting component one 43 can fit against the inner side wall and inner top wall of the groove 21, and the limiting component two 44 fits against the bottom of the aluminum alloy busbar trough 2. There are gaps between the two side limiting blocks 32, the two sets of limiting components 43, and the two sets of limiting components 44, and the cutting component 13 can move through the gaps.

[0041] In the above scheme, through the design of the outer limiting mechanism 3 and the inner limiting mechanism 4, when cutting the aluminum alloy busbar 2, the outer side of the cutting point of the aluminum alloy busbar 2 can be fully supported and limited. When the electric cylinder 134 is controlled to move the bracket 132 down to cut the aluminum alloy busbar 2, the shear stress generated by the cutting disc 133 pressing down into the aluminum alloy busbar 2 is effectively avoided. Since the groove 21 in the aluminum alloy busbar 2 has no internal support, the stress cannot be evenly distributed, which leads to plastic deformation of the groove wall and improves the yield of the aluminum alloy busbar 2 cutting process.

[0042] In this embodiment, the cutting assembly 13 includes a mounting block 131 installed on the top of the support frame 12. Vertical telescopic rods are symmetrically fixed on the mounting block 131. A bracket 132 is fixed at the bottom of the two telescopic rods. An electric cylinder 134 connected to the bracket 132 is fixedly installed on the mounting block 131. A cutting disc 133 is rotatably connected to the bracket 132. It should be noted that the mounting structure of the cutting disc 133 and the driving structure for driving the cutting disc 133 to rotate are existing technologies and will not be described in detail here. The aluminum alloy busbar trough 2 includes a side plate, and a top plate and a bottom plate are integrally formed on the top and bottom of the side plate, respectively. The top plate and the bottom plate are close to each other and are integrally formed with a raised edge strip, which is located at the end away from the side plate. The side plate, the top plate, the bottom plate and the two raised edge strips form a groove 21.

[0043] In this embodiment, the telescopic connection assembly 42 includes a telescopic rod 2 that is horizontally oriented and fixedly installed on the mounting base 41. A connecting frame 421 is fixedly installed at the telescopic end of the telescopic rod 2. An electric cylinder 2 422 that is fixedly connected to the connecting frame 421 is fixedly installed on the mounting base 41.

[0044] In this embodiment, the limiting component 43 includes a fixed seat 431 mounted on the connecting frame 421. Vertical telescopic rods 3 are symmetrically fixed to the top of the fixed seat 431. Support seats 432 are fixedly mounted on the top of the two telescopic rods 3. Electric cylinders 3 433 connected to the support seats 432 are fixedly mounted on the top of the fixed seat 431. Support frame 434 is mounted on the top of the support seat 432. Upper limit plate 435 is mounted on the side of the support frame 434 away from the mounting seat 41. Guide limiting plates 436 are fixedly mounted in a horizontal linear array at the bottom of the upper limit plate 435. Lower limit plates 437 are vertically slidably connected to the multiple guide limiting plates 436. The lower limit plates 437 are connected to the end of the fixed seat 431.

[0045] In this embodiment, the limiting component 44 includes a connecting block 441, a guide rod that moves vertically through the fixing seat 431, the connecting block 441 is fixedly connected to the bottom of the guide rod, an adjusting screw 442 that is threaded vertically through the fixing seat 431, the adjusting screw 442 is rotatably connected to the connecting block 441, and a support frame 443 that fits against the bottom of the aluminum alloy busbar trough 2 is fixedly installed at the end of the connecting block 441.

[0046] In this embodiment, the bottom of the support frame 434 is symmetrically fixed with auxiliary support mechanisms 5, which are all in contact with the bottom wall of the groove 21. The auxiliary support mechanism 5 includes an upper plate 51 fixedly installed at the bottom of the support frame 434. The bottom of the upper plate 51 is symmetrically fixed with vertical telescopic rods four. The bottom of the two telescopic rods four is fixedly connected to a lower plate 52. The bottom of the upper plate 51 is fixedly installed with an electric cylinder four 53 connected to the lower plate 52. The bottom of the lower plate 52 is fixedly installed with a contact block 54.

[0047] In the above scheme, by setting up auxiliary support mechanism 5, before cutting the aluminum alloy busbar trough 2, the support frame 434 is made to fit against the inner top wall of the groove 21, and the support frame 443 is made to fit against the bottom of the aluminum alloy busbar trough 2. Then, the electric cylinders 53 of the two sets of auxiliary support mechanisms 5 are controlled to drive the lower plate 52 to move down, so that the contact block 54 fits against the inner bottom wall of the groove 21. This achieves the effect of supporting the inside of the groove 21 of the aluminum alloy busbar trough 2 through the auxiliary support mechanism 5, improving the internal support stability of the aluminum alloy busbar trough 2, and further avoiding the plastic deformation of the groove wall of the aluminum alloy busbar trough 2 when it is cut. In addition, the support rod 434 2. When the support rod 4341 rotates, it drives the contact block 54 in the auxiliary support mechanism 5 to move. Under the magnetic attraction between the electromagnet 4434 and the contact block 54, the electromagnet 4434 drives the support rod 4432 to rotate around the support rod 4431. This causes the support frame 443 and the support frame 434 to form a parallelogram shape synchronously. Under the magnetic attraction between the electromagnet 4434 and the contact block 54, the overall shape of the support frame 443 is fixed. This ensures the stability of the support during the cutting and processing of the busbar trunking, and also effectively avoids damage to the support structure during the processing, thus improving the safety and reliability of the equipment operation.

[0048] In this embodiment, a positioning hole 4211 is provided on the side of the connecting frame 421 away from the telescopic rod 2. A positioning block 4311 is integrally formed on the fixing seat 431. The positioning block 4311 can move through the positioning hole 4211, and the outer side wall of the positioning block 4311 is in contact with the inner side wall of the positioning hole 4211. One end of the positioning block 4311 that passes through the positioning hole 4211 is threaded with a bolt 4312 that contacts the inner side wall of the connecting frame 421. The installation assembly 31 includes a vertical plate 311 installed on the inner side wall of the support frame 12. A horizontal telescopic rod 5 is fixedly installed on the vertical plate 311. A fixing plate 312 is fixedly connected to the end of the telescopic rod 5. A horizontal threaded sleeve 313 is rotatably connected to the side of the vertical plate 311 near the fixing plate 312. A threaded rod 314 is threaded through the end of the threaded sleeve 313 in a horizontal direction. The threaded rod 314 is fixedly connected to the fixing plate 312. Both of the side limiting blocks 32 are fixedly connected to the side wall of the fixing plate 312.

[0049] In this embodiment, the mounting block 131 is rotatably mounted on the support frame 12, and the motor 121 is fixedly mounted on the support frame 12. The output shaft of the motor 121 is connected to the mounting block 131 through a bevel gear assembly. Both of the two side limiting blocks 32 have a clearance slope on the side that is close to each other, and the clearance slopes in the two side limiting blocks 32 are perpendicular to each other. The upright plate 311 is horizontally slidably mounted on the support frame 12 via an electric slider one, and the mounting base 41 is horizontally slidably mounted on the support frame 12 via an electric slider two; An actuator 6 is installed on the support frame 12. The actuator 6 is communicatively connected to an external main controller, and the device can be controlled by the main controller. The actuator 6 is communicatively connected to the motor 121, the electric slider one, and the electric slider two.

[0050] In this embodiment, the support frame 434 includes a support rod 4341 fixedly installed on the top of the support base 432. Both ends of the support rod 4341 are hinged to horizontal support rods 4342. The free ends of the two support rods 4342 are hinged to the same support rod 4343. The support rod 4343 is the same length as the support rod 4341. A sliding rod 4344 moves horizontally through the middle of the support rod 4343. An upper limit plate 435 is fixedly connected to the end of the sliding rod 4344. The other end of the sliding rod 4344 is horizontally slidably connected to the support rod 4341. The upper limit plate 435 is horizontally slidably connected to the support base 432. The lower limit plate 437 is horizontally slidably connected to the fixed base 431. A motor 4345 for driving one of the support rods 4342 to rotate is fixedly installed at the bottom of the support rod 4341. The support frame 443 includes a support rod 4431 fixedly installed at the end of the connecting block 441. Both ends of the support rod 4431 are hinged to horizontal support rods 4432. The free ends of the two support rods 4432 are hinged to the same support rod 4433. The support rod 4433 is the same length as the support rod 4431. An installation hole is provided at the top of the support rod 4432, directly below the contact block 54. An electromagnet 4434 is fixedly installed in the installation hole. The contact block 54 is made of iron. (The last sentence appears to be incomplete and possibly refers to a different topic.) When the shearing section is tilted, the two motors 4345, four electromagnets 4434, and electric slider one and electric slider two work together to make the support frame 443 and the support frame 434 synchronously form a parallelogram shape. This allows the cutting disc 133 to be pressed down and cut while providing all-round support and limiting effect on the outside of the shearing section of the aluminum alloy busbar trough 2. This effectively avoids plastic deformation of the trough wall when the shearing section of the aluminum alloy busbar trough 2 is tilted, which helps to improve the yield of the tilted shearing process of the aluminum alloy busbar trough 2.

[0051] In this embodiment, the execution component 6 includes industrial cameras symmetrically fixedly installed on the inner top wall of the support frame 12. Specifically, the industrial cameras are communicatively connected to an external main controller. During the cutting process of the aluminum alloy busbar 2, the industrial cameras capture images of the cutting disc 133 in real time. When the cutting disc 133 is damaged, the images of the cutting disc 133 are fed back to the main controller. The main controller performs a differential comparison between the real-time captured images and the pre-stored standard cutting disc 133 contour template. If the contour difference exceeds a preset threshold, the cutting disc 133 is determined to be damaged. This achieves real-time monitoring of the cutting disc 133 during the cutting process of the aluminum alloy busbar 2, effectively preventing uneven cutting force caused by the damaged cutting disc 133 during continuous cutting of the aluminum alloy busbar 2, which could lead to tearing of the aluminum alloy busbar 2 and the appearance of a large number of sharp burrs and tears on the cut surface. This helps to improve the yield rate of the aluminum alloy busbar 2 cutting process. The two sides of the support frame 12 Two suction hoods 7 are symmetrically fixedly installed, and both suction hoods 7 are connected to external negative pressure equipment. By setting the suction hoods 7, when cutting the aluminum alloy busbar 2, the external negative pressure equipment is controlled to draw the air out of the two suction hoods 7, so that the air on the opposite sides of the two suction hoods 7 flows into the two suction hoods 7 respectively. When the air flows, it drives the dust generated by cutting the aluminum alloy busbar 2 to flow synchronously into the two suction hoods 7, so as to achieve the effect of absorbing and cleaning the dust generated by cutting the aluminum alloy busbar 2. This effectively avoids the debris adhering to the industrial camera lens and causing image blurring and obstruction, and ensures that the camera completely captures the outline image of the cutting disc 133, thereby reducing the probability of misjudgment and missed detection during image recognition by the main controller, and further helps to improve the yield of the aluminum alloy busbar 2 cutting process. A roller conveyor 8 is provided on one side of the support platform 11. The top of the roller conveyor 8 is flush with the top of the support platform 11. By setting the roller conveyor 8, it is convenient to transport the aluminum alloy busbar 2 being cut to the bottom of the cutting disc 133.

[0052] Working principle and usage process of this invention: When using this shearing equipment to shear the busbar trough, the aluminum alloy busbar trough 2 is placed on top of the roller conveyor 8, with the groove 21 located on the side away from the side limit block 32. The roller conveyor 8 transports the aluminum alloy busbar trough 2 towards the support platform 11, causing the shearing point of the aluminum alloy busbar trough 2 to be displaced below the cutting disc 133. The cutting disc 133 rotates at high speed on the support 132, and then the electric cylinder 134 is controlled to move the support 132 downward, thereby cutting the aluminum alloy busbar trough 2 and achieving the shearing effect of the aluminum alloy busbar trough 2.

[0053] Through the design of the outer limiting mechanism 3 and the inner limiting mechanism 4, when cutting the aluminum alloy busbar 2, after the shearing point of the aluminum alloy busbar 2 is moved to below the cutting disc 133, the side plate part in the aluminum alloy busbar 2 is first made to fit with the two side limiting blocks 32. Then, the electric cylinder 422 of the two sets of telescopic connecting components 42 is controlled to drive the connecting frame 421 to move towards the aluminum alloy busbar 2, so that the limiting component 43 extends into the groove 21, so that the upper limiting plate 435 and the lower limiting plate 435 are connected. All 37 are in contact with the inner sidewall of the groove 21. Then, the electric cylinder 433 drives the support base 432 to move upward, so that the support frame 434 is in contact with the inner top wall of the groove 21. During this process, when the support frame 434 moves upward, it drives the upper limit plate 435 to move upward synchronously, and drives multiple guide limit plates 436 to move upward synchronously on the lower limit plate 437, without affecting the upward movement of the support base 432 driven by the electric cylinder 433. At this time, the support frame 443 of the limit component 2 44 is located below the aluminum alloy busbar 2. Rotating the adjusting screw 442 moves the connecting block 441 upward, causing the support frame 443 to fit against the bottom of the aluminum alloy busbar trough 2. This achieves support and limitation of the inner top wall of the groove 21 by the support frame 434 of the two sets of limiting components 1 43, and support and limitation of the side plate portion of the aluminum alloy busbar trough 2 by the two side limiting blocks 32 and the upper limiting plate 435 and lower limiting plate 437 of the two sets of limiting components 1 43. The support frame 443 of the two sets of limiting components 2 44 provides support and limitation of the aluminum alloy busbar trough 2. The positioning system can provide all-round support and limiting effect on the outer side of the shearing point of the aluminum alloy busbar 2. When the electric cylinder 134 moves the support 132 downward to cut the aluminum alloy busbar 2, it effectively avoids the shearing stress generated by the cutting disc 133 pressing down and cutting into the aluminum alloy busbar 2. Since the groove 21 in the aluminum alloy busbar 2 has no internal support, the stress cannot be evenly distributed, which leads to plastic deformation of the groove wall and improves the yield of the shearing process of the aluminum alloy busbar 2.

[0054] By setting up auxiliary support mechanism 5, before cutting the aluminum alloy busbar trough 2, the support frame 434 is made to fit against the inner top wall of the groove 21, and the support frame 443 is made to fit against the bottom of the aluminum alloy busbar trough 2. Then, the electric cylinders 53 of the two sets of auxiliary support mechanisms 5 are controlled to drive the lower plate 52 to move down, so that the contact block 54 fits against the inner bottom wall of the groove 21. This achieves the effect of supporting the inside of the groove 21 of the aluminum alloy busbar trough 2 through the auxiliary support mechanism 5, improving the internal support stability of the aluminum alloy busbar trough 2, and further avoiding the plastic deformation of the groove wall of the aluminum alloy busbar trough 2 when it is cut.

[0055] By designing the positioning block 4311 and positioning hole 4211, when cutting aluminum alloy busbar troughs 2 of different widths, the bolt 4312 can be disassembled to remove the limiting effect on the positioning block 4311, thereby disassembling the fixing seat 431. This allows for the disassembly and replacement of the first limiting component 43 and the second limiting component 44, ensuring that the width between the support frame 434 of the first limiting component 43 and the upper limiting plate 435 is the same as the width of the groove 21. This allows for precise cutting of aluminum alloy busbar troughs 2 of different widths. The groove 21 of the alloy busbar 2 provides stable support, improving the applicability of the equipment. Furthermore, through the design of the threaded sleeve 313 and the threaded rod 314, when cutting aluminum alloy busbar 2 of different widths, rotating the threaded sleeve 313 can cause the fixed plate 312 to move along the telescopic rod, adjusting the position of the two side limiting blocks 32. This ensures that when the cutting point of the aluminum alloy busbar 2 is located below the cutting disc 133, the two side limiting blocks 32 can limit the side plate portion in the aluminum alloy busbar 2.

[0056] When it is necessary to perform inclined shearing on the cutting section of the aluminum alloy busbar 2, the motor 121 is controlled to rotate its output shaft, which drives the mounting block 131 to rotate on the bracket 132 through the bevel gear assembly, thereby driving the cutting disc 133 to rotate, causing the cutting disc 133 to deflect horizontally. Thus, when cutting the aluminum alloy busbar 2, the cutting section of the aluminum alloy busbar 2 can be inclinedly sheared without the need for horizontal rotation of the aluminum alloy busbar 2, which would cause the end of the aluminum alloy busbar 2 to shift outward, thereby reducing the space required for inclined shearing of the aluminum alloy busbar 2.

[0057] When the output shaft of the control motor 121 rotates, causing the cutting disc 133 to deflect horizontally, the industrial camera captures the image information of the deflected cutting disc 133 and feeds it back to the main controller. The main controller then controls the two motors 4345, four electromagnets 4434, and two electric sliders to operate. The operation of electric slider 1 drives the vertical plate 311 to slide horizontally, causing the two side limit blocks 32 to translate, so that the cutting disc 133 can pass between the two side limit blocks 32 when it moves downward. At this time, the control motor 1 stops working. During this period, the inclined surfaces of the two side limit blocks 32 on opposite sides make way for the cutting disc 133, without affecting the downward pressing action of the cutting disc 133. The control motor 2 drives the vertical plate 311 to move horizontally. The mounting base 41 slides in opposite directions with the upright plate 311, while simultaneously controlling the two motors 4345 to operate, causing the second support rod 4342 to rotate on the first support rod 4341. During this process, the third support rod 4343 rotates with the second support rod 4342, causing the support frame 434 to form a parallelogram shape. The third support rod 4343 moves closer to the first support rod 4341 along the sliding rod 4344, and drives the sliding rod 4344 to slide along the first support rod 4341. Through the sliding rod 4344, the upper limit plate 435 slides horizontally along the support base 432, and the lower limit plate 437 slides synchronously along the fixed base 431. When the second support rod 4342 is parallel to the cutting disc 133, the control motor 4345 stops working, thus supporting the... The overall shape of the support frame 434 is fixed to ensure the stability of the support during the cutting and processing of the busbar trunking, while also effectively preventing damage to the support structure during processing, thus improving the safety and reliability of the equipment operation. When the cutting disc 133 can move through the opposite sides of the two support frames 434 and the two supporting frames 443, the electric slider 2 is controlled to stop working, positioning the two sets of limit components 1 43 and the two sets of limit components 2 44. Furthermore, when the electromagnet 4434 is energized, it generates a magnetic attraction force on the contact block 54. Due to the low magnetic susceptibility of aluminum alloy, the electromagnet 4434 does not generate an effective magnetic attraction force on the aluminum alloy busbar trunking 2, thus preventing the aluminum alloy busbar trunking 2 from being attracted. When the second support rod 4342 rotates on the first support rod 4341, it drives the contact block 54 in the auxiliary support mechanism 5 to move. Under the magnetic attraction between the electromagnet 4434 and the contact block 54, the second support rod 4432 rotates around the first support rod 4431 through the electromagnet 4434. This causes the support frame 443 and the support frame 434 to form a parallelogram shape synchronously. Under the magnetic attraction between the electromagnet 4434 and the contact block 54, the overall shape of the support frame 443 is fixed. This ensures the support stability during the cutting and processing of the busbar trunking, while also effectively preventing damage to the support structure during processing, thus improving the safety and reliability of the equipment operation.Therefore, when performing inclined shearing on the cutting section of the aluminum alloy busbar 2, the cooperation of two motors 4345, four electromagnets 4434, and electric slider one and electric slider two causes the support frame 443 and the support frame 434 to simultaneously form a parallelogram shape. This achieves the effect of making way for the downward cutting of the cutting disc 133 while providing all-round support and limiting effect on the outer side of the cutting section of the aluminum alloy busbar 2. This effectively avoids plastic deformation of the trough wall when performing inclined shearing on the cutting section of the aluminum alloy busbar 2, and helps to improve the yield rate of inclined shearing processing of aluminum alloy busbar 2.

[0058] During the cutting process of the aluminum alloy busbar 2, the industrial camera captures images of the cutting disc 133 in real time. When the cutting disc 133 is damaged, the image of the cutting disc 133 is fed back to the main controller. The main controller performs a differential comparison between the real-time captured image and the pre-stored standard cutting disc 133 contour template. If the contour difference exceeds a preset threshold, the cutting disc 133 is determined to be damaged. This achieves real-time monitoring of the cutting disc 133 during the cutting process of the aluminum alloy busbar 2, effectively preventing uneven cutting force caused by the damaged cutting disc 133 when cutting the aluminum alloy busbar 2, which would tear the aluminum alloy busbar 2 during the cutting process and cause a large number of sharp burrs and tears on the cut surface. This helps to improve the yield rate of the aluminum alloy busbar 2 cutting process.

[0059] By setting up suction hoods 7, when cutting the aluminum alloy busbar 2, the external negative pressure device is controlled to draw the air out of the two suction hoods 7, so that the air on the opposite sides of the two suction hoods 7 flows into the two suction hoods 7 respectively. When the air flows, it drives the dust generated by cutting the aluminum alloy busbar 2 to flow into the two suction hoods 7 simultaneously, thereby achieving the effect of absorbing and cleaning the dust generated by cutting the aluminum alloy busbar 2. This effectively avoids debris adhering to the industrial camera lens and causing image blurring and obstruction, ensuring that the camera can completely capture the outline image of the cutting disc 133, thereby reducing the probability of misjudgment and missed detection during image recognition by the main controller, and further helping to improve the yield rate of the aluminum alloy busbar 2 cutting process.
