Detailed Implementation

[0053] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0054] like Figure 1 As shown, embodiments of this application disclose a cutting and welding production line, including a main material strip feeding assembly 1 arranged sequentially along the material strip movement direction, a first main material strip welding assembly 2 for welding parts to the front section of the main material strip, a second main material strip welding assembly 3 for welding parts to the rear section of the main material strip, a roll-to-roll waste cutting assembly 4 for removing waste from the material strip, a first thrust testing assembly 5 for performing thrust testing on the welded assembly, a first L-shaped welding assembly 6 and a second L-shaped welding assembly 7 for welding L-shaped parts to the main material, an L-shaped part breaking assembly 8 for breaking off the waste connecting end of the L-shaped part, and a second thrust testing assembly 9 for detecting the welding firmness of the L-shaped part;

[0055] It also includes an L-shaped part feeding mechanism 10 disposed on one side of the first L-shaped welding assembly 6 and the second L-shaped welding assembly 7;

[0056] The L-shaped part feeding mechanism 10 includes an L-shaped part feeding assembly 110, an L-shaped part cutting assembly 120, and a material distribution mechanism 130 that distributes the L-shaped parts after cutting to the first L-shaped welding assembly 6 and the second L-shaped welding assembly 7 respectively.

[0057] In practice, the main material feeding assembly 1 feeds the main material strip, causing it to move sequentially to the first main material strip welding assembly 2 and the second main material strip welding assembly 3. Then, the external conveying assembly transports the parts to be welded to the first and second main material strip welding assemblies 2 and 3 for welding. Next, the product continues to be conveyed to the roll-to-roll waste cutting assembly 4, which removes waste from the strip. The product then continues to be conveyed to the first thrust testing assembly 5, which checks whether the upper and lower layers of the product are firmly welded. After the test, the product is conveyed to… The first L-shaped welding assembly 6 and the second L-shaped welding assembly 7, and the L-shaped part feeding mechanism 10 respectively distribute the L-shaped parts to the first L-shaped welding assembly 6 and the second L-shaped welding assembly 7. The main material is welded to the L-shaped part by the first L-shaped welding assembly 6 and the second L-shaped welding assembly 7. After welding, the product is conveyed to the L-shaped part breaking assembly 8. The L-shaped part breaking assembly 8 breaks off the waste material at the end of the L-shaped part. After breaking, the product is conveyed to the second thrust testing assembly 9. The second thrust testing assembly 9 detects whether the upper and lower products are welded firmly, thus completing the production of the entire product.

[0058] In this structure, the coordinated use of the main strip feeding assembly 1, the first main strip welding assembly 2, the second main strip welding assembly 3, the roll-to-roll waste cutting assembly 4, the first thrust testing assembly 5, the first L-shaped welding assembly 6, the second L-shaped welding assembly 7, the L-shaped part breaking assembly 8, the second thrust testing assembly 9, and the L-shaped part feeding mechanism 10 enables fully automatic welding of products, thereby improving the overall welding efficiency.

[0059] In this embodiment, both the main material strip feeding assembly 1 and the L-shaped part feeding assembly 110 include a material tray 101 and a material tray drive motor for driving the material tray 101 to rotate. A material channel 102 is provided on one side of the material tray 101, and a grounding wire induction rod 103 is provided on the material channel 102. When there is no electrical signal from the grounding wire induction rod 103, the material tray 101 rotates to release material. A waste roll collection rack is provided on one side of the material tray 101, and a winding rod 104 is provided on the waste roll collection rack. A spring is provided between the winding rod 104 and the waste roll collection rack so that the waste paper on the winding rod 104 can come into contact with the material tray.

[0060] It should be explained that current will be supplied to the material channel 102 and the grounding induction rod 103. When the material strip in the material channel 102 comes into contact with the grounding induction rod 103, the material channel 102, the grounding induction rod 103 and the material strip will form a loop and generate current.

[0061] Specifically, during operation, the material strip is installed in the material tray 101. The material tray drive motor drives the material tray 101 to rotate and feed the material. During normal feeding, the material strip will not contact the grounding wire induction rod 103, and the grounding wire induction rod 103 has no electrical signal. The material tray drive motor continues to work. When the feeding is too long, the material strip will jump up and contact the grounding wire induction rod 103, generating current in the grounding wire induction rod 103. At this time, the material tray drive motor stops working and waits for the grounding wire induction rod 103 to stop flowing before continuing to work. At the same time, during the feeding process, there is a layer of waste paper on one side of the material strip. The waste paper will be wound around the winding rod 104. Under the action of the spring, the waste paper on the winding rod 104 will always be in contact with the material tray 101. Under the action of friction, the rotation of the material tray 101 will drive the winding rod 104 to rotate together, thereby enabling the winding rod 104 to wind up the waste paper.

[0062] In this structure, the grounding wire induction rod 103 enables automatic material feeding, reducing the possibility of too much or too little material being fed. At the same time, the winding rod 104 enables automatic collection of waste material.

[0063] In this embodiment, both the first main strip welding assembly 2 and the second main strip welding assembly 3 include a first welding frame. The first welding frame is provided with a first main channel plate 201 for the main material channel 102 to pass through. Below the first main channel plate 201 are a first lower pressure block mounting plate 202 and a first lifting drive cylinder 203 for driving the first lower pressure block mounting plate 202 to move up and down. Above the first main channel plate 201 is a first upper pressure block mounting plate 204. Below the first lifting drive cylinder 203 is a second lifting drive cylinder 205 for driving the first upper pressure block mounting plate 204 to move up and down. At the bottom of the first upper pressure block mounting plate 204 is a first lower pressure block. The first lower pressure block mounting plate 202 has a first upper pressure block that cooperates with the first lower pressure block on its upper surface. The first lower pressure block mounting plate 202 has a retractable first part positioning pin 206 on its upper surface. The bottom end of the first part positioning pin 206 is provided with a third lifting drive cylinder 207 for driving the first part positioning pin 206 to extend out of the upper surface of the first lower pressure block mounting plate 202. The first lower pressure block mounting plate 202 is also provided with a first material strip positioning pin 208 for positioning the material strip. The first upper pressure block mounting plate 204 has a notch that exposes the welding point of the product. The first laser welding assembly 209 for welding is provided above the first upper pressure block mounting plate 204.

[0064] Specifically, during operation, the main material belt moves to the first main channel plate 201, the first part positioning pin 206 is in the extended state, the part is transported by the external mechanism to the first lower pressure block mounting plate 202 and positioned by the first part positioning pin 206. Then, the first lifting drive cylinder 203 drives the first lower pressure block mounting plate 202 to rise, and the second lifting drive cylinder 205 drives the first upper pressure block mounting plate 204 to fall, so that the part and the main material belt are pressed together. The main material belt is positioned by the first material belt positioning pin 208. At this time, the main material belt and the part are pressed together by the first upper pressure block and the first lower pressure block. The first laser welding assembly 209 welds the main material belt and the part. After welding is completed, the third lifting drive cylinder 207 first drives the first part positioning pin 206 to fall, so that the first part positioning pin 206 exits the product. Then, the first lifting drive cylinder 203 drives the first lower pressure block mounting plate 202 to fall, and the second lifting drive cylinder 205 drives the first upper pressure block mounting plate 204 to rise, and the product continues to flow to the next station.

[0065] The above structure enables precise positioning of the main material strip and parts during welding. At the same time, after welding is completed, the third lifting drive cylinder 207 first drives the first part positioning pin 206 to descend, thereby preventing the first part positioning pin 206 from pulling the product skewed when the first pressing block mounting plate 202 descends, thus ensuring the product yield.

[0066] In this embodiment, a precision positioning pin 210 is also provided below the first upper pressure block mounting plate 204. The first lower pressure block mounting plate 202 is provided with a pin hole that cooperates with the precision positioning pin 210. When the first upper pressure block mounting plate 204 moves downward and the first lower pressure block mounting plate 202 moves upward, the precision positioning pin 210 passes through the main channel plate and extends into the pin hole. A detection block is provided on one side of the first upper pressure plate mounting plate, and a sensor mounting block is provided on one side of the lower pressure plate mounting plate. A displacement detection sensor 211 is provided on the sensor mounting block.

[0067] Specifically, when the first upper pressure block mounting plate 204 and the first lower pressure block mounting plate 202 move towards each other, the precision positioning pin 210 can be inserted into the pin hole, thereby ensuring the position accuracy of the first upper pressure block mounting plate 204 and the first lower pressure block mounting plate 202. At the same time, during the movement, the displacement detection sensor 211 can detect the distance between the first upper pressure block mounting plate 204 and the first lower pressure block mounting plate 202. When the detected distance is inaccurate, it means that there may be a problem such as material jamming, and the material strip needs to be checked to ensure the yield rate of subsequent product production.

[0068] In this embodiment, both the roll-to-roll waste cutting assembly 4 and the L-shaped part cutting assembly 120 include a cutting frame. The cutting frame is provided with a lower mold 401 and an upper mold 402 located above the lower mold 401. A first electric cylinder 403 for driving the upper mold 402 to move downward is provided above the upper mold 402. A cutter for cutting off the connection between the product and the waste is provided at the lower end of the upper mold 402.

[0069] The bottom end of the cutting machine frame is also equipped with a waste discharge mechanism 404 for collecting waste materials.

[0070] Specifically, when the cutting operation is performed, when the main material channel 102 moves between the lower mold 401 and the upper mold 402, the first electric cylinder 403 drives the upper mold 402 to move downward, and the cutter below the upper mold 402 cuts off the connection between the product and the waste material. The cut waste material is discharged through the waste discharge mechanism 404.

[0071] It should be explained that the waste discharge mechanism 404 described above can be a take-up roll, on which the waste strip is pre-wound, and the waste is collected by the winding of the take-up roll. The above structure can also be designed as a waste discharge pipe, through which the waste is sucked away.

[0072] In this embodiment, both the first thrust testing component 5 and the second thrust testing component 9 include a thrust detection frame. An elastic upper pressure block 501 is provided on the thrust detection frame, and a support plate 502 is provided below the elastic upper pressure block 501. An obstacle clearance groove 503 is provided on the support plate 502, corresponding to the product. A plurality of detection rods 504 corresponding to the obstacle clearance grooves 503 are provided on one side of the support plate 502. A drive rod is provided on the side of the detection rod 504 away from the support plate 502. The assembly also includes a second electric cylinder 505 that drives the drive rod to move horizontally. A force detection sensor 506 is provided between the drive rod and the detection rod 504. The assembly also includes a fourth lifting drive cylinder 507 that drives the elastic upper pressure block 501 to press down and a fifth lifting drive cylinder 508 that drives the support plate 502 to move up and down.

[0073] During the specific testing, the product is supported by the support plate 502. The elastic upper pressure block 501 descends, and under the action of the fourth lifting drive cylinder 507 and the fifth lifting drive cylinder 508, the upper product is pressed between the elastic lower pressure block and the support plate 502. Then, the second electric cylinder 505 drives the detection rod 504 to extend into the clearance groove 503 and contact the lower part, and apply pressure to the lower part. At this time, the detection sensor can detect the thrust at this time, and judge whether the main product and the part are firmly welded by the magnitude of the thrust.

[0074] In this structure, the thrust testing component allows for the pushing of lower-level parts while the main product is being pressed down, thereby enabling the detection of weld strength through thrust testing.

[0075] In this embodiment, both the first L-shaped welding assembly 6 and the second L-shaped welding assembly 7 include a second welding frame. The second welding frame is provided with a second main channel plate 601 for the main material channel 102 to pass through. Below the second main channel plate 601 is a second lower pressure block mounting plate 602 and a sixth lifting drive cylinder 603 for driving the second lower pressure block mounting plate 602 to move up and down. Above the second main channel plate 601 is a second upper pressure block mounting plate 604. Above the second lifting drive cylinder 205 is a device for driving the second upper pressure block mounting plate 604 to move up and down. The seventh lifting drive cylinder 605, the bottom of the second upper pressure block mounting plate 604 is provided with a second lower pressure block, the upper surface of the second lower pressure block mounting plate 602 is provided with a second upper pressure block that cooperates with the second lower pressure block, the upper surface of the second lower pressure block mounting plate 602 is provided with a second part positioning pin 606 for positioning L-shaped parts, the second lower pressure block mounting plate 602 is also provided with a second material strip positioning pin 607 for positioning material strip, and a second laser welding assembly 608 for welding and a smoke extraction assembly 609 for extracting smoke are provided below the second lower pressure block mounting plate 602;

[0076] The second lower pressure block mounting plate 602 is provided with an L-shaped part welding position with a welding notch, and the bottom surface of the second lower pressure block mounting plate 602 is provided with a trumpet-shaped groove 610 that converges towards the welding notch.

[0077] In specific operation, the main material belt flows to the second main channel plate 601, the second part positioning pin 606 is in the extended state, the L-shaped part is transported by the external mechanism to the second lower pressure block mounting plate 602 and positioned by the second part positioning pin 606. Then, the sixth lifting drive cylinder 603 drives the second lower pressure block mounting plate 602 to rise, and the seventh lifting drive cylinder 605 drives the first upper pressure block mounting plate 204 to fall, so that the L-shaped part is pressed together with the main material belt. The main material belt is positioned by the first material belt positioning pin 208. At this time, the main material belt and the L-shaped part are pressed together by the second upper pressure block and the second lower pressure block. The second laser welding assembly 608 welds the main material belt and the L-shaped part. After welding is completed, the second part positioning pin 606 falls, so that the second part positioning pin 606 exits the product. Then, the sixth lifting drive cylinder 603 drives the second lower pressure block mounting plate 602 to fall, and the seventh lifting drive cylinder 605 drives the second upper pressure block mounting plate 604 to rise, and the product continues to flow to the next station.

[0078] The above structure enables precise positioning of the main strip and L-shaped parts during welding. At the same time, since the bottom surface of the second lower pressure block mounting plate 602 is provided with a funnel-shaped groove 610 that converges towards the welding gap, it can avoid the laser line during welding, prevent the laser line from damaging the second lower pressure block mounting plate 602, and also facilitate the exhaust of welding fumes.

[0079] In this embodiment, the L-shaped part breaking assembly 8 includes a breaking frame, a third main channel plate 801 is provided inside the breaking frame, a third upper pressure block 802 mounting plate and an eighth lifting drive cylinder 803 are provided above the third main channel plate 801 to drive the third upper pressure block 802 mounting plate to perform lifting and lowering movements, a third lower pressure block 804 mounting plate and a thirteenth lifting drive cylinder 805 are provided below the third main channel plate 801 to drive the third lower pressure block 804 mounting plate to perform lifting and lowering movements, and a third upper pressure block 802 is provided at the lower part of the third upper pressure block 802 mounting plate. The upper surface of the mounting plate of the lower pressure block 804 is provided with a third lower pressure block 804 that cooperates with the third upper pressure block 802. The system also includes a break-off drive plate and a ninth lifting drive cylinder 806 for driving the break-off drive plate to move up and down. The break-off drive plate is provided with an upper ejector pin 807 for abutting the upper surface of the break-off part and a lower ejector pin 808 for abutting the lower surface of the break-off part. The break-off drive plate is also provided with a tenth lifting drive cylinder 809 for driving the upper ejector pin 807 to move up and down and an eleventh lifting drive cylinder 810 for driving the lower ejector pin 808 to move up and down.

[0080] Specifically, when the main material belt moves to the third main channel plate 801, the eighth lifting drive cylinder 803 drives the third upper pressure block 802 mounting plate to descend, and the thirteenth lifting drive cylinder 805 drives the third lower pressure block 804 mounting plate to rise, so that the third upper pressure block 802 and the third lower pressure block 804 can press the main material belt tightly. Then, the tenth lifting drive cylinder 809 drives the upper ejector pin 807 to descend, and the eleventh lifting drive cylinder 810 drives the lower ejector pin 808 to rise, so that the upper ejector pin 807 and the lower ejector pin 808 clamp the waste end of the L-shaped part. Then, the ninth lifting drive cylinder 806 drives the break-off drive plate to perform reciprocating lifting and lowering motion, so that the upper ejector pin 807 and the lower ejector pin 808 break off the waste part.

[0081] In this embodiment, the material distribution mechanism 130 includes a receiving component. Rotating components and a spacing conveying component for transporting L-shaped parts on the receiving component to the rotating component are provided on both sides of the receiving component.

[0082] The receiving assembly includes a receiving base plate 1301, a twelfth lifting drive cylinder 1302 for driving the receiving base plate 1301 to move up and down, and a first horizontal drive module 1303 for driving the receiving base plate 1301 to the spacing and conveying assembly. The receiving base plate 1301 is provided with a first placing rod 1304 and a second placing rod 1305. A guide rod is provided between the second placing rod 1305 and the first placing rod 1304.

Multiple receiving rods 1308 are provided at intervals on both the first placing rod 1304 and the second placing rod 1305. A second positioning pin 1309 is provided on the surface of the receiving rod 1308.

[0083] The rotating assembly includes a second horizontal drive module 1310, the drive end of which is equipped with a rotating module. The rotating module includes a rotating mounting plate 1311, a suction cup fixing plate 1312 at the bottom center of the rotating mounting plate 1311, side plates 1313 on both sides of the suction cup fixing plate 1312 that are horizontally slidably connected to the rotating mounting plate 1311, and multiple connecting rods 1314. One end of each connecting rod 1314 is rotatably connected to the side plate 1313, and the other end is rotatably connected to the suction cup fixing plate 1312. A suction cup 1315 for picking up products is provided at one end of the connecting rod 1314 below the suction cup fixing plate 1312. A side plate drive cylinder 1316 for driving the side plate 1313 to move horizontally is provided on one side of the end of the side plate 1313.

[0084] Specifically, after the L-shaped part cutting assembly 120 cuts the L-shaped part, the L-shaped part falls onto the receiving base plate 1301. Positioned by the second positioning pin 1309, the positioning hole of the product falls onto the second positioning pin 1309. Then, the first horizontal drive cylinder 1307 drives the second placing rod 1305 to move, realizing lateral displacement of the product. Next, the first horizontal drive module 1303 drives the receiving base plate 1301 to the spacing and conveying assembly, which picks up the part. The product on the base plate 1301 is transferred to the rotating assembly. When the product is on the rotating assembly, it is fixed by the suction cup 1315. The side plate drive cylinder 1316 drives the side plate 1313 to move horizontally, causing the connecting rod 1314 to move. In turn, the connecting rod 1314 drives the suction cup 1315 to rotate, realizing the rotation of the L-shaped part. After the rotation of the L-shaped part is completed, the suction cup 1315 transfer assembly transfers the L-shaped part on the rotating assembly to the first L-shaped welding assembly 6 and the second L-shaped welding assembly 7 respectively.

[0085] It should be noted that the suction cup 1315 handling assembly can use the existing suction cup 1315 handling mechanism, which will not be elaborated here.

[0086] This structure enables the handling and displacement of products, ensuring that the products fall into the subsequent workstations one by one after the displacement is changed. At the same time, the simultaneous rotation of multiple products can be achieved by driving the linkage 1314.
