Description

Technical Field

[0001] This utility model relates to the field of laser welding equipment technology, specifically to an automatic edge alignment and pressing fixture. Background Technology

[0002] In precision metal processing, particularly in new energy and electronic components, it is often necessary to weld the ends of two metal strips (such as stainless steel, aluminum alloy, and copper alloy) to form a continuous production strip. This metal strip needs to pass through various narrow guide channels at high speed and continuously in subsequent processes. Therefore, the straightness of the welded metal strip and the smoothness of the joint are extremely important. Specifically, before welding the ends of the two metal strips, the ends must be precisely aligned and pressed together.

[0003] However, existing metal strip alignment mainly relies on manual visual adjustment. Therefore, manual adjustment is inefficient and inconsistent. Especially for ultra-wide metal strips, such as those with a width of 150-800mm, it is difficult to align the ends of two metal strips synchronously. This results in obvious steps or misalignments in the welded metal strips. When passing through the flow channel at high speed, the metal strips are prone to jamming, scratching, and breaking, leading to production line shutdowns and product scrap. Utility Model Content

[0015] As a further improvement to the above technical solution, the pressing assembly includes a support plate, a cantilever, a second cylinder, and a pressing claw. The support plate is disposed on the side of the transfer platform near the other transfer platform. The cantilever is disposed on the transfer platform. The second cylinder is mounted on the cantilever. The pressing claw is connected to the telescopic end of the second cylinder. The pressing claw is located directly above the support plate. The second cylinder is used to drive the pressing claw to move closer to or away from the support plate.

Detailed Implementation

[0031] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0032] Reference Figure 1 and Figure 2 An example of this utility model provides an automatic edge alignment and pressing fixture, which includes a material transfer mechanism 1, a positioning mechanism and a pressing mechanism.

[0033] Specifically, the material transfer mechanism 1 includes two material transfer platforms 11 and a dual-actuator linear module 12 for driving the two material transfer platforms 11 to move independently. The material transfer platform 11 is used to carry metal strips.

[0034] Furthermore, the positioning mechanism includes two automatic edge-aligning components 2, which are respectively mounted on two material transfer platforms 11. Each automatic edge-aligning component 2 includes a reference block 21, a vertical plate 22, a lifting module 23 mounted on the vertical plate 22, and a rolling module 24 mounted on the lifting module 23. The reference block 21 and the vertical plate 22 are mounted on the material transfer platform 11. The reference block 21 is located inside the vertical plate 22, and the inner side of the reference block 21 is a straight reference edge. The lifting module 23 is used to drive the rolling module 24 to lift and lower. The rolling module 24 is used to move the metal strip on the material transfer platform 11 closer to the reference block 21 so that the side of the metal strip is aligned with the straight reference edge of the reference block 21.

[0035] Furthermore, it includes two pressing assemblies 3, which are respectively disposed on two material transfer platforms 11. The pressing assemblies 3 are used to press the metal strip.

[0036] Before welding the two metal strips, the two metal strips are placed on the two transfer platforms 11 respectively. Then, the lifting module 23 drives the rolling module 24 to descend, so that the rolling module 24 comes into contact with the metal strips on the transfer platform 11. Then, the rolling module 24 moves the metal strips on the transfer platform 11 closer to the reference block 21, so that the side of the metal strip is aligned with the straight reference edge of the reference block 21. Subsequently, the pressing assembly 3 presses the metal strips tightly. Finally, the double-acting linear module 12 drives the two transfer platforms 11 to move independently, transferring the metal strips to the corresponding working positions for subsequent processing. This can realize automatic edge alignment of the two metal strips, improve production efficiency, ensure the welding quality of the metal strips, and ensure that the metal strips do not warp during the welding process.

[0037] In some preferred embodiments, the rolling module 24 includes a support 241, a roller 242 rotatably connected to the support 241, and a motor 243 for driving the roller 242 to rotate. The axis of the roller 242 is parallel to the straight reference edge of the reference block 21.

[0038] Understandably, the lifting module 23 drives the rolling module 24 to descend as a whole, causing the roller 242 to press against the surface of the metal strip. The motor 243 drives the roller 242 to rotate. Since the axis of the roller 242 is parallel to the straight reference edge of the reference block 21, the linear velocity direction of the contact point between the roller 242 and the metal strip is perpendicular to the straight reference edge of the reference block 21. The friction between the roller 242 and the metal strip is converted into a lateral traction force perpendicular to the straight reference edge of the reference block 21. Therefore, the roller 242 drives the metal strip to move in a direction perpendicular to the straight reference edge of the reference block 21 until the side of the metal strip is completely pressed against the straight reference edge of the reference block 21. This achieves high-precision edge alignment of the metal strip. Moreover, the rolling friction between the roller 242 and the metal strip reduces damage to the metal strip.

[0039] Specifically, roller 242 is a rubber roller, which allows roller 242 to make flexible contact with the metal strip, further reducing damage to the metal strip. At the same time, it can increase the friction between roller 242 and metal strip and prevent slippage.

[0040] Furthermore, the motor 243 and the roller 242 are driven by a reduction gear set 244. The reduction gear set 244 includes a first gear 2441, a second gear 2442 and a third gear 2443 that mesh in sequence. The first gear 2441 is connected to the output shaft of the motor 243. The second gear 2442 is rotatably connected to the support 241 through the first rotating shaft 2444. The third gear 2443 is rotatably connected to the support 241 through the second rotating shaft 2445. The roller 242 is connected to the end of the second rotating shaft 2445.

[0041] It should be noted that the diameter of the second gear 2442 is larger than the diameter of the first gear 2441 and smaller than the diameter of the third gear 2443.

[0042] Understandably, motor 243 drives the first gear 2441 to rotate at a higher speed and lower torque. The first gear 2441 meshes with the second gear 2442, causing the second gear 2442 to rotate. At this time, the speed of the second gear 2442 decreases, and the output torque increases. The second gear 2442 drives the first rotating shaft 2444 to rotate synchronously. The first rotating shaft 2444 rotates relative to the support 241. Then, the second gear 2442 meshes with the third gear 2443, causing the third gear 2443 to rotate. At this time, the third gear... The rotational speed of 2443 is further reduced, and the output torque is further increased. The third gear 2443 drives the second rotating shaft 2445 and the roller 242 to rotate synchronously. The second rotating shaft 2445 rotates relative to the support 241, so that the roller 242 rotates at a lower speed and a higher torque. Thus, only a small motor 243 is needed to drive the roller 242 to generate a large traction force to move the metal strip, reducing the manufacturing cost of the equipment. At the same time, it can avoid the phenomenon of metal strip overshoot caused by the motor 243 directly driving the roller 242, and improve the stability of the metal strip during the edge alignment process.

[0043] Specifically, each rolling module 24 is equipped with two rollers 242, which are respectively connected to both ends of the second rotating shaft 2445. When the motor 243 drives the second rotating shaft 2445 to rotate through the reduction gear set 244, the two rollers 242 installed at both ends of the second rotating shaft 2445 rotate synchronously. The two rollers 242 press against the surface of the metal strip at the same time and jointly drive the metal strip to align with the straight reference edge of the reference block 21. This ensures the force balance of the metal strip, prevents the metal strip from deflecting during movement, ensures the reliability of the metal strip movement, and improves the alignment accuracy of the metal strip.

[0044] In some preferred embodiments, the lifting module 23 includes a first cylinder 231, which is mounted on the upright plate 22. The telescopic end of the first cylinder 231 is connected to the support 241. A guide rail is provided on one side of the upright plate 22, and the guide rail is vertically arranged. A slider is provided on one side of the support 241, and the slider is slidably connected to the guide rail.

[0045] Understandably, the first cylinder 231 drives the support 241 to rise and fall, thereby driving the entire rolling module 24 to rise and fall. At the same time, the slider fixed on the support 241 slides along the vertically set guide rail, thereby ensuring that the entire rolling module 24 moves in the vertical direction and avoids shaking or deflection. In this way, it ensures that the axis of the roller 242 remains parallel to the straight reference edge of the reference block 21, improving the stability of the equipment.

[0046] Furthermore, a tension module 25 is provided between the upright plate 22 and the support 241. The tension module 25 includes two connecting seats 251 and at least one tension spring 252. One connecting seat 251 is located on the top of the upright plate 22, and the other connecting seat 251 is located on the support 241. The two ends of the tension spring 252 are respectively connected to the two connecting seats 251.

[0047] In the initial state, the extension end of the first cylinder 231 is in the retracted state, and the tension spring 252 is in a slightly stretched state.

[0048] When the first cylinder 231 drives the support 241 to descend, the tension spring 252 is stretched and stores elastic potential energy.

[0049] When the first cylinder 231 drives the support 241 to rise, the stretched spring 252 releases its stored elastic potential energy, generating a continuous upward pulling force, thereby reducing the load on the first cylinder 231 and extending the service life of the first cylinder 231.

[0050] When the air supply to the first cylinder 231 is suddenly interrupted or a leak occurs in the first cylinder 231, the tension of the tension spring 252 can pull the entire rolling module 24 to stay in the rising position, preventing the rolling module 24 from falling rapidly under its own weight and causing it to collide with the product or equipment, thus ensuring the safety of the equipment.

[0051] In some preferred embodiments, the pressing assembly 3 includes a support plate 31, a cantilever 32, a second cylinder 33, and a pressing claw 34. The support plate 31 is disposed on one side of the transfer platform 11 near another transfer platform 11. The cantilever 32 is disposed on the transfer platform 11. The second cylinder 33 is mounted on the cantilever 32. The pressing claw 34 is connected to the telescopic end of the second cylinder 33. The pressing claw 34 is located directly above the support plate 31. The second cylinder 33 is used to drive the pressing claw 34 to move closer to or away from the support plate 31.

[0052] Understandably, during the conveying or edge alignment of the metal strip, the second cylinder 33 drives the pressure claw 34 away from the support plate 31. At this time, the metal strip can move freely on the transfer platform 11 or be pulled by the rolling module 24. When the side of the metal strip is aligned with the straight reference edge of the reference block 21, the second cylinder 33 drives the pressure claw 34 to approach the support plate 31, so that the pressure claw 34 presses the metal strip on the support plate 31. The structure of the second cylinder 33 is simple, thereby reducing the manufacturing cost of the equipment. Moreover, the action of the second cylinder 33 is rapid, which can realize the rapid pressing or releasing of the metal strip.

[0053] Reference Figure 3 Furthermore, the pressure claw 34 is elongated, and its length extends along the width of the metal strip. The pressure claw 34 includes an elongated support base 341 and a plurality of pressure blocks 342 disposed at the bottom of the elongated support base 341. The elongated support base 341 is connected to the telescopic end of the second cylinder 33. The plurality of pressure blocks 342 are arranged sequentially along the length of the elongated support base 341. A floating component 343 is disposed between the elongated support base 341 and the pressure blocks 342.

[0054] Understandably, the elongated pressure claws 34 ensure that the metal strip is consistently pressed along its width, preventing edge warping. The floating component 343 prevents uneven pressing caused by uneven metal strip surfaces, impurities, or uneven support plate 31 surfaces. It also buffers the impact of the pressure block 342 on the metal strip, preventing indentations or damage to its surface.

[0055] Specifically, the floating component 343 includes two bolts 3431 and two first springs 3432. The shank of the bolts 3431 has a smooth shaft section and a threaded section. The elongated support base 341 is provided with two vertical through holes corresponding to the position of each pressure block 342. The top of the pressure block 342 is provided with two threaded holes corresponding to the through holes. The smooth shaft section passes through the through holes and can slide up and down. The first springs 3432 are sleeved on the outer periphery of the smooth shaft section. The threaded section is threadedly connected to the threaded hole. The two ends of the first springs 3432 abut against the bottom of the elongated support base 341 and the top of the pressure block 342, respectively.

[0056] Understandably, the first spring 3432 provides preload, keeping the pressure block 342 in its lowest position under natural conditions. When the second cylinder 33 extends to drive the pressure claw 34 to descend as a whole, the bottom of the pressure block 342 first contacts the metal strip on the support plate 31. Then, the second cylinder 33 continues to extend, and the pressure block 342 is fixed in place by the support resistance of the support plate 31. The elongated support base 341 continues to descend. At this time, the first spring 3432 is compressed, and the optical axis section of the bolt 3431 slides in the through hole of the elongated support base 341. The elastic force of the first spring 3432 acts on the pressure block 342, causing the pressure block 342 to press the metal strip tightly onto the support plate 31. Thus, it can be ensured that the metal strip can be pressed by the pressure block 342 at every position in the width direction.

[0057] In some preferred embodiments, a leveling mechanism 4 is also included. The leveling mechanism 4 includes a first leveling block 41, a second leveling block 42 and a third cylinder 43. The first leveling block 41 is connected to one side of one of the support plates 31, and the second leveling block 42 is connected to one side of the other support plate 31. The first leveling block 41 extends toward the second leveling block 42 to form an extension 44. The third cylinder 43 is connected to one of the material transfer platforms 11 through a cylinder mounting seat 45, and the telescopic rod of the third cylinder 43 is located directly below the extension 44.

[0058] When the dual-actuator linear module 12 drives the two material transfer platforms 11 to approach each other, the two support plates 31 abut against each other, the extension 44 is located directly above the second leveling block 42, and the telescopic rod of the third cylinder 43 extends to drive the second leveling block 42 to abut against the extension 44.

[0059] Understandably, after the ends of the two metal strips are cut, the end faces of the two metal strips are flush with the edges of the two support plates 31 respectively. When the ends of the two metal strips need to be welded together, the double-acting linear module 12 drives the two transfer platforms 11 to move closer to each other until the two support plates 31 fixed on the two transfer platforms 11 abut against each other, completing the coarse positioning between the two support plates 31. At this time, the extension 44 of the first leveling block 41 connected to one support plate 31 is located directly above the second leveling block 42 on the other support plate 31, and the telescopic rod of the third cylinder 43 is in the retracted state and located directly below the second leveling block 42. Then, the telescopic rod of the third cylinder 43 extends upward and drives the second leveling block 42 to lift slightly upward until the upper surface of the second leveling block 42 is in complete contact with and pressed against the lower surface of the extension 44, thereby making the two support plates 31 at the same horizontal height, and thus making the ends of the two metal strips at the same horizontal height, ensuring the welding quality of the two metal strips.

[0060] Reference Figure 1 and Figure 4In some preferred embodiments, the leveling mechanism 4 further includes a snap-fit ​​assembly 46, which includes a pin seat 461, a pin 462, and a second spring 463. The pin seat 461 is disposed at the bottom of the second leveling block 42, the second leveling block 42 is provided with a pin hole 421 for the pin 462 to pass through, the extension 44 is provided with a snap-fit ​​interface 441 for accommodating the insertion of the pin 462, the bottom end of the pin 462 is provided with a boss 464, and the second spring sleeve 463 is disposed on the outer periphery of the pin 462. A stepped hole 4611 is provided inside. The large hole of the stepped hole 4611 accommodates the boss 464 to slide up and down. The small hole of the stepped hole 4611 accommodates the second spring 463. The two ends of the second spring 463 abut against the bottom of the second leveling block 42 and the top of the boss 464, respectively. A limit block 465 is provided at the bottom of the pin seat 461. The limit block 465 extends to the bottom end of the stepped hole 4611. A space is provided between the limit block 465 and the stepped hole 4611 for the insertion of the telescopic rod of the third cylinder 43.

[0061] In the initial state, the third cylinder 43 is in the retracted state, and the second spring 463 is in the pre-compressed state. The elastic force of the second spring 463 pushes the boss 464 downward, causing the boss 464 and the pin 462 to move downward until the bottom of the boss 464 abuts against the limiting block 465. At this time, the top of the pin 462 retracts into the pin hole 421 of the second leveling block 42, and the top of the pin 462 is lower than the upper surface of the second leveling block 42. Thus, the pin 462 is prevented from scraping against the extension 44 when the two support plates 34 abut against each other.

[0062] When the dual-actuator linear module 12 drives the two transfer platforms 11 to approach each other until the two support plates 31 fixed on the two transfer platforms 11 abut against each other, the extension 44 of the first leveling block 41 is located directly above the second leveling block 42. At this time, the locking interface 441 of the extension 44 corresponds to the pin hole 421 of the second leveling block 42. Then, the telescopic rod of the third cylinder 43 extends upward to insert into the stepped hole 4611 and pushes the boss 464 and the pin 462 upward. At this time, the second spring 463 is compressed, and the top of the pin 462 extends out of the pin hole 421 of the second leveling block 42 and is locked into the locking interface 441 of the extension 44. Thus, the first leveling block 41 and the second leveling block 42 can be locked together to prevent the two support plates 31 from separating or misaligning due to vibration or external force during subsequent welding.

[0063] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
