[0004] The aforementioned patent achieves the goals of preheating the workpiece and removing surface impurities before welding, isolating the external oxygen with nitrogen during welding to prevent oxidation of the weld joint, improving welding quality, and achieving local nitrogen filling during welding. It also aims to ensure the amount of nitrogen filling at the weld joint while reducing nitrogen consumption. However, when welding seals, the rubber material of the seals makes it difficult to fix their position before welding, thus affecting the quality of the welded seals. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a welding device for seal processing, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a welding device for processing seal strips, comprising an operating table, a flat plate fixedly mounted on the top of the operating table, a heating device disposed on the top of the flat plate, a worktable fixedly mounted on the top of the operating table, a feeding device disposed on the top of the operating table, the feeding device including a driving device, a sliding groove formed on the top of the worktable, the driving device disposed on the top of the sliding groove, a clamp fixedly mounted on the top of the driving device, and an electric push rod fixedly mounted on the top of the driving device. A baffle is fixedly installed at the output end of the fixture. A transmission inclined block is slidably installed inside the fixture. An inclined vertical rod slides through the fixture. A groove is opened inside the fixture. A limit plate is rotatably and slidably installed on the inner wall of the groove. A locking plate is rotatably installed on the inner wall of the groove. A locking block is fixedly installed on the top of the limit plate. The movement of the limit plate drives the locking block to move to the top and contact the seal. After the locking block contacts the seal, the seal can no longer move. The top of the operating table is equipped with a protective device for buffering the feeding device and a demolding device for cooling the fixture.

[0007] According to the above technical solution, a triangular block is fixedly installed on the top of the limiting plate, and a reset plate is fixedly installed on the bottom of the baffle, so that the device is reset to the initial state after welding is completed and the welded seal is pushed out.

[0008] According to the above technical solution, a first spring is provided between the limiting plate and the groove, and a first torsion spring is provided between the locking plate and the groove. The first spring drives the limiting plate to reset, and the first torsion spring drives the locking plate to reset.

[0009] According to the above technical solution, the protective device includes: a hollow box, a sliding plate, a clamping plate, an arc-shaped plate, and a transmission rod. The hollow box is fixedly installed on the top of the driving device. The sliding plate is slidably installed on the inner wall of the hollow box. The clamping plate is fixedly installed on the top of the sliding plate. The arc-shaped plate is slidably installed on the inner wall of the hollow box. The transmission rod is fixedly installed on the top of the sliding plate. A through groove is provided on the surface of the transmission rod, so that the baffle cannot move quickly when it moves away from the clamp.

[0010] According to the above technical solution, the protective device further includes: a through rod, a connecting rod, a pressing rod, and a contact rod. The through rod is fixedly installed on the side of the arc-shaped plate near the transmission rod. The connecting rod is fixedly installed on the surface of the baffle. The pressing rod is fixedly installed at the bottom of the connecting rod. The contact rod slides through the inner and outer walls of the hollow box and the driving device. The contact rod is fixedly connected to the sliding plate. The movement of the sliding plate drives the clamping plate to move to the top. After the clamping plate moves, it limits the arc-shaped plate again.

[0011] According to the above technical solution, a second spring is provided between the arc-shaped plate and the hollow box, and a third spring is provided between the sliding plate and the hollow box. The third spring drives the sliding plate to reset, and the second spring drives the arc-shaped plate to reset.

[0012] According to the above technical solution, the demolding device includes: an inflation box, an air outlet pipe, a hollow tube, a fixing block, a U-shaped rod, a sealing plate, a T-shaped block, and two sealing baffles. The inflation box is fixedly installed on the top of the workbench, the air outlet pipe is fixedly installed on the top of the inflation box, the hollow tube is fixedly installed on the surface of the inflation box and communicates with the inflation box, the fixing block is fixedly installed on the bottom of the inner wall of the driving device, the sealing plate is slidably installed on the inner wall of the hollow tube, one end of the U-shaped rod is slidably installed on the side of the sealing plate away from the inflation box, the other end of the U-shaped rod slides through the surface of the fixing block, the T-shaped block is fixedly installed on the top of the U-shaped rod, and both sealing baffles are slidably installed on the side of the sealing plate away from the inflation box. The T-shaped block is fixedly connected to the sealing baffles, so that when the sealing plate is inflated, it can draw air into the interior of the inflation box through the opening on its surface, and when it is sprayed, it completely closes to increase the air pressure.

[0013] According to the above technical solution, a No. 4 spring is provided between the loop rod and the fixed block, and the contact rod contacts the loop rod, and the No. 4 spring drives the loop rod to reset.

[0014] This invention provides a welding apparatus for processing seals. It has the following advantages:

[0015] (1) In this invention, the limiting plate moves the card block to the top and contacts the seal. After the card block contacts the seal, the seal can no longer move, so that the seal is limited after it moves to a fixed position. This prevents the seals on both sides from being inaccurately positioned, which would result in insufficient connection during welding and ensure the quality of the welded seal. The inclined vertical rod moves the transmission inclined block to the direction of the seal and pushes out the welded seal. This allows the device to return to its initial state after welding and push out the welded seal, making it convenient to pick up the welded seal and weld it again. This improves the comfort of using the device and effectively improves work efficiency.

[0016] (2) In this invention, the baffle moves and comes into contact with the arc plate. The baffle moves and rubs against the arc plate. As the friction between the baffle and the arc plate increases, the baffle cannot move quickly when it moves away from the fixture. This prevents the seal from being pulled outward before it is shaped after welding, which would cause the weld to break and ensure production quality.

[0017] (3) In this invention, after the arc plate is no longer blocked by the clamping plate, the second spring resets and drives the arc plate to move into the interior of the hollow box, so that the arc plate no longer contacts the clamping plate after the baffle is retracted to the farthest point, so that the baffle will not be blocked when processing again, thus improving work efficiency. The sliding plate moves and drives the clamping plate to the top. After the clamping plate moves, it limits the arc plate again, making it convenient for reuse. This reduces the resistance encountered when the electric push rod is pushed out, thus improving the service life of the device.

[0018] (4) In this invention, the moving of the U-shaped rod drives the moving of the sealing plate and squeezes the air inside the hollow tube and the air box to be sprayed out through the air outlet. After the welding is completed, the device will spray air at the weld to make the weld cool down quickly, preventing the demolding when the seal is not completely cooled, thus preventing welding failure and ensuring the stability of the operation. The moving of the T-shaped block drives the sealing baffle to move to the bottom and overlaps with the opening on the surface of the sealing plate. When the sealing plate is inflated, it can suck air into the air box through the opening on the surface and completely close the air pressure when the air is sprayed. This ensures that the device is not affected by resistance when inflating and increases the cooling effect when the air is sprayed, thus improving the practicality of the device.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1 - Figure 8 One embodiment of the present invention is: a welding device for processing seal strips, including an operating table 1, a flat plate 2 fixedly installed on the top of the operating table 1, a heating device 3 provided on the top of the flat plate 2, a workbench 4 fixedly installed on the top of the operating table 1, a feeding device provided on the top of the operating table 1, the feeding device including a driving device 51, a slide groove opened on the top of the workbench 4, the driving device 51 being located on the top of the slide groove, a clamp 52 fixedly installed on the top of the driving device 51, an electric push rod 53 fixedly installed on the top of the driving device 51, a baffle 54 fixedly installed at the output end of the electric push rod 53, a transmission inclined block 55 slidably installed inside the clamp 52, an inclined vertical rod 56 slidably passing through the inside of the clamp 52, a groove opened inside the clamp 52, a limit plate 57 rotatably and slidably installed on the inner wall of the groove, a locking plate 58 rotatably installed on the inner wall of the groove, and a locking block 59 fixedly installed on the top of the limit plate 57 to prevent the seal strips on both sides from being inaccurately positioned, resulting in insufficient connection during welding, thus ensuring the quality of the welded seal strips.

[0030] A triangular block 511 is fixedly installed on the top of the limiting plate 57, and a reset plate 510 is fixedly installed on the bottom of the baffle 54, which facilitates the removal of the welded seal and re-welding, improving the comfort of the device during use and effectively improving work efficiency.

[0031] A first spring is provided between the limiting plate 57 and the groove, and a first torsion spring is provided between the locking plate 58 and the groove. The first spring drives the limiting plate 57 to reset, and the first torsion spring drives the locking plate 58 to reset.

[0032] In this embodiment, during operation: the seal is aligned with the groove on the surface of the clamp 52, and then pushed towards the heating device 3. The seal moves and contacts the transmission inclined block 55, causing it to move away from the baffle 54. This movement brings the inclined block 55 into contact with the inclined vertical rod 56, causing it to move towards the bottom. The inclined vertical rod 56 then contacts the locking plate 58, causing it to rotate towards the bottom. After rotation, the locking plate 58 no longer contacts the limiting plate 57, releasing it from its limiting position. Once the limiting plate 57 is no longer restricted, it is reset by the first spring. The moving limit plate 57 moves upward, causing the locking block 59 to move upward and contact the seal. Once in contact with the seal, the locking block 59 prevents further movement. Then, the heating device 3 is activated, heating the ends of the seals that are close together. The driving device 51 then moves the seals in the direction they are close together. The heated seals press against each other, causing them to fuse together, completing the seal processing. This process limits the seals after they reach a fixed position, preventing inaccurate positioning that could lead to insufficient welding and ensuring the quality of the welded seals. After welding is completed, the output end of the electric push rod 53 moves away from the clamp 52. This movement causes the baffle 54 to move in the opposite direction away from the clamp 52. After moving, the baffle 54 is no longer in contact with the seal. The baffle 54 then moves away from the clamp 52 along with the reset plate 510. The reset plate 510 then contacts the triangular block 511 and moves it to the bottom. The triangular block 511 moves, causing the limiting plate 57 to move to the bottom. The limiting plate 57 moves, causing the locking block 59 to move to the bottom. After moving, the locking block 59 is no longer in contact with the seal. After activation, the first torsion spring resets the locking plate 58, causing it to rotate towards the limiting plate 57 and contact it. After the limiting plate 57 contacts the locking plate 58, it is again limited. The rotation of the locking plate 58 causes the inclined vertical rod 56 to move to the top. The movement of the inclined vertical rod 56 causes the transmission inclined block 55 to move towards the seal and push out the welded seal. This allows the device to reset to its initial state after welding and push out the welded seal, making it convenient to pick up the welded seal and weld it again. This improves the comfort of using the device and effectively increases work efficiency.

[0033] Please see Figure 1 - Figure 8Based on the above embodiments, in another embodiment of the present invention, the top of the operating table 1 is provided with a protective device for buffering the feeding device and a demolding device for cooling the clamp 52. The protective device includes a hollow box 61, a sliding plate 62, a clamping plate 63, an arc-shaped plate 65, and a transmission rod 66. The hollow box 61 is fixedly installed on the top of the driving device 51. The sliding plate 62 is slidably installed on the inner wall of the hollow box 61. The clamping plate 63 is fixedly installed on the top of the sliding plate 62. The arc-shaped plate 65 is slidably installed on the inner wall of the hollow box 61. The transmission rod 66 is fixedly installed on the top of the sliding plate 62. A through groove is provided on the surface of the transmission rod 66 to prevent the seal from being pulled outward after welding but before it is fully shaped, which would cause the weld to break and ensure production quality.

[0034] The protective device also includes: a through rod 67, a connecting rod 68, a pressing rod 69, and a contact rod 610. The through rod 67 is fixedly installed on the side of the arc plate 65 near the transmission rod 66. The connecting rod 68 is fixedly installed on the surface of the baffle 54. The pressing rod 69 is fixedly installed at the bottom of the connecting rod 68. The contact rod 610 slides through the inner and outer walls of the hollow box 61 and the drive device 51. The contact rod 610 is fixedly connected to the sliding plate 62 for easy reuse, which reduces the resistance encountered when the electric push rod 53 is pushed out and improves the service life of the device.

[0035] A second spring 64 is provided between the arc-shaped plate 65 and the hollow box 61, and a third spring is provided between the sliding plate 62 and the hollow box 61. The third spring drives the sliding plate 62 to reset, and the second spring 64 drives the arc-shaped plate 65 to reset.

[0036] The demolding device includes: an inflation box 71, an air outlet pipe 72, a hollow tube 73, a fixing block 74, a U-shaped rod 75, a sealing plate 76, a T-shaped block 77, and two sealing baffles 78. The inflation box 71 is fixedly installed on the top of the workbench 4, the air outlet pipe 72 is fixedly installed on the top of the inflation box 71, the hollow tube 73 is fixedly installed on the surface of the inflation box 71 and communicates with the inflation box 71, the fixing block 74 is fixedly installed on the bottom of the inner wall of the drive device 51, the sealing plate 76 is slidably installed on the inner wall of the hollow tube 73, and one end of the U-shaped rod 75 is slidably installed on the sealing plate 76 away from the inflation box. On one side of box 71, the other end of the U-shaped rod 75 slides through the surface of the fixed block 74, so that after welding is completed, the device will spray air onto the weld to cool the weld quickly, preventing demolding before the seal is completely cooled, thus ensuring the stability of the operation. The T-shaped block 77 is fixedly installed on the top of the U-shaped rod 75, and both sealing baffles 78 are slidably installed on the side of the sealing plate 76 away from the inflation box 71. The T-shaped block 77 is fixedly connected to the sealing baffles 78, ensuring that the device is not affected by resistance during inflation and increasing the cooling effect during air spraying, thereby improving the practicality of the device.

[0037] A No. 4 spring is provided between the loop rod 75 and the fixed block 74. The contact rod 610 contacts the loop rod 75, and the No. 4 spring drives the loop rod 75 to reset.

[0038] In this embodiment, during operation: the baffle 54 moves and contacts the arc-shaped plate 65, causing friction between them. This increased friction prevents the baffle 54 from moving quickly away from the clamp 52, thus preventing the seal from being pulled outwards before it is fully shaped after welding, ensuring production quality. The movement of the baffle 54 drives the connecting rod 68 towards the hollow box 61, where it contacts the transmission rod 66. This movement drives the transmission rod 66 to move to the bottom, which in turn drives the sliding plate 62 to move to the bottom. The sliding plate 62 then drives the clamping plate 63 to move to the bottom. After the clamping plate 63 moves, it no longer contacts the arc-shaped plate 65, and the arc-shaped plate 65, no longer blocked by the clamping plate 63, passes through the second spring. The reset mechanism 64 moves the arc plate 65 into the hollow box 61, ensuring that the arc plate 65 no longer contacts the baffle 54 after the baffle 54 retracts to its furthest point. This prevents the baffle 54 from being obstructed during subsequent processing, improving work efficiency. When the connecting rod 68 moves towards the clamp 52, it drives the pressing rod 69 towards the clamp 52. The movement of the pressing rod 69 drives the through rod 67 towards the arc plate 65, which in turn moves the arc plate 65 away from the hollow box 61. After the arc plate 65 moves, it resets via the third spring, causing the sliding plate 62 to move to the top. The movement of the sliding plate 62 then drives the clamping plate 63 to move to the top. After the clamping plate 63 moves, it again limits the arc plate 65, facilitating reuse and reducing resistance when the electric push rod 53 is pushed out, thus extending the device's lifespan.

[0039] When the drive device 51 moves towards each other, it moves the fixed block 74 towards the air box 71. The fixed block 74 moves the return rod 75, which in turn moves the sealing plate 76 away from the air box 71. After welding is completed, the drive device 51 moves away from each other, moving the fixed block 74. The fixed block 74 moves the return rod 75 towards the air box 71, which in turn moves the sealing plate 76, compressing the air inside the hollow tube 73 and the air box 71 and expelling it through the air outlet pipe 72. This causes the device to spray air onto the weld after welding is completed. The welding joint is cooled quickly to prevent demolding before the seal is fully cooled, which could lead to welding failure and ensure operational stability. The sliding plate 62 moves, causing the contact rod 610 to move to the bottom. The contact rod 610 then contacts the loop rod 75 and moves the loop rod 75 to the bottom. The loop rod 75 moves, causing the T-block 77 to move to the bottom. The T-block 77 moves, causing the sealing baffle 78 to move to the bottom and overlap with the opening on the surface of the sealing plate 76. This allows the sealing plate 76 to draw air into the air box 71 through the opening on its surface during inflation and to completely close during air release, increasing the air pressure. This ensures that the device is not affected by resistance during inflation and increases the cooling effect during air release, improving the practicality of the device.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
