A protection device for buffering the feeding device and a demolding device for cooling the clamp are arranged on the top of the operating table.

[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 returns to the initial state after welding is completed and ejects the welded seal.

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

[0009] According to the above technical solution, the protection device includes: a hollow box, a sliding plate, a clamping plate, an arc 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 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, and a through groove is opened on the surface of the transmission rod, so that when the baffle moves away from the clamp, it cannot move quickly.

[0010] According to the above technical solution, the protection device further includes: a through rod, a connecting rod, a pressing rod and a contact long rod. The through rod is fixedly installed on the side of the arc plate close to 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 long rod is slidably penetrated through the inner and outer walls of the hollow box and the driving device, and the contact long rod is fixedly connected with the sliding plate.

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 air inflation box, an air outlet pipe, a hollow pipe, a fixed block, a return-shaped rod, a sealing plate, a T-shaped block and two sealing baffles.

[0013] According to the above technical solution, a fourth spring is arranged between the return-shaped rod and the fixed block, the contact long rod contacts the return-shaped rod, and the fourth spring drives the return-shaped rod to reset.

[0014] The present invention provides a welding device for seal processing. It has the following beneficial effects:

[0015] (1) In this invention, the movement of the limiting plate drives the block to move upward and contact the seal. After the block contacts the seal, the seal can no longer move, so that the seal is limited after moving to a fixed position, preventing the inaccurate positions of the seals on both sides from causing insufficient connection during welding, ensuring the quality of the welded seal. The movement of the inclined surface vertical rod drives the transmission inclined block to move towards the seal and eject the welded seal, so that the device resets to the initial state after welding is completed, and the welded seal is ejected, facilitating the taking of the welded seal and welding again, improving the comfort during the use of the device and effectively improving the work efficiency.

[0016] (2) In this invention, the movement of the baffle will contact the arc-shaped plate, and there will be mutual friction between the moving baffle and the arc-shaped plate. Since the friction force between the baffle and the arc-shaped plate increases, when the baffle moves away from the fixture, it cannot move quickly, preventing the seal from being pulled outward before being fully shaped after welding, resulting in the disconnection of the welded part and ensuring the production quality.

[0017] (3) In this invention, after the arc-shaped plate is no longer blocked by the clamping plate, it is reset by the second spring to drive the arc-shaped plate to move towards the inside of the hollow box, so that after the baffle is retracted to the farthest position, the arc-shaped plate no longer contacts the baffle, ensuring that the baffle will not be blocked during the next processing, improving work efficiency. By moving the sliding plate to drive the clamping plate to move upwards, the clamping plate will limit the arc-shaped plate again after moving, facilitating reuse, reducing the resistance when the electric push rod is pushed out, and increasing the service life of the device.

[0018] (4) In this invention, the movement of the return-shaped rod drives the movement of the sealing plate to squeeze the air inside the hollow tube and the inflatable box to be ejected through the air outlet pipe, so that after welding is completed, the device will jet air at the welding area to quickly cool the welding area, preventing welding failure caused by demolding before the sealant is completely cooled and ensuring the stability of the work. By moving the T-shaped block to drive the sealing baffle to move downwards and coincide with the opening on the surface of the sealing plate, the sealing plate can inhale air into the inside of the inflatable box through the opening on the surface during inflation, and completely close during jetting to increase air pressure, ensuring that the device will not be affected by resistance during inflation and increasing the cooling effect during jetting, improving the practicality of the device.

Specific embodiments

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1 - Figure 8 An embodiment of the present invention is: A welding device for seal processing, including an operating table 1, a flat panel 2 is fixedly installed on the top of the operating table 1, a heating device 3 is arranged on the top of the flat panel 2, a workbench 4 is fixedly installed on the top of the operating table 1, a feeding device is arranged on the top of the operating table 1, the feeding device includes a driving device 51, a chute is opened on the top of the workbench 4, the driving device 51 is arranged on the top of the chute, a fixture 52 is fixedly installed on the top of the driving device 51, an electric push rod 53 is fixedly installed on the top of the driving device 51, a baffle 54 is fixedly installed at the output end of the electric push rod 53, a transmission inclined block 55 is slidably installed inside the fixture 52, an inclined plane vertical rod 56 is slidably penetrated inside the fixture 52, a groove is opened inside the fixture 52, a limit plate 57 is rotatably and slidably installed on the inner wall of the groove, a clamping plate 58 is rotatably installed on the inner wall of the groove, a clamping block 59 is fixedly installed on the top of the limit plate 57, preventing the inaccurate positions of the seals on both sides from causing insufficient connection during welding and ensuring the quality of the welded seals.

[0030] A triangular block 511 is fixedly installed on the top of the limit plate 57, and a reset plate 510 is fixedly installed at the bottom of the baffle 54, which is convenient for taking the welded seals and welding them again, improving the comfort during the use of the device and effectively improving the work efficiency.

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

[0032] When this embodiment works: Align the seal with the groove on the surface of the fixture 52, and then push the seal in the direction close to the heating device 3. The movement of the seal will contact the transmission inclined block 55. The movement of the seal drives the transmission inclined block 55 to move away from the baffle 54. The movement of the transmission inclined block 55 will contact the inclined surface vertical rod 56 and drive the inclined surface vertical rod 56 to move downward. The movement of the inclined surface vertical rod 56 will contact the clamping plate 58 and drive the clamping plate 58 to rotate downward. After the clamping plate 58 rotates, it no longer contacts the limiting plate 57 and releases the limit on the limiting plate 57. After the limiting plate 57 is no longer limited, the first spring drives the limiting plate 57 to move upward. The movement of the limiting plate 57 drives the clamping block 59 to move upward and contact the seal. After the clamping block 59 contacts the seal, the seal can no longer move. Then start the heating device 3. After the heating device 3 heats one end of the seal close to each other, the driving device 51 moves to drive the seal to move in the direction close to each other. The seals are heated and pressed against each other, so that the two seals are fused together to complete the seal processing. It makes the seal be limited after moving to a fixed position, preventing the inaccurate positions of the seals on both sides from causing insufficient connection during welding and ensuring the quality of the welded seal. After welding is completed, the output end of the electric push rod 53 moves in the direction away from the fixture 52. The movement of the output end of the electric push rod 53 drives the baffle 54 to move in the opposite direction away from the fixture 52. After the baffle 54 moves, it no longer contacts the seal. The movement of the baffle 54 drives the reset plate 510 to move in the direction away from the fixture 52. The movement of the reset plate 510 will contact the triangular block 511 and drive the triangular block 511 to move downward. The movement of the triangular block 511 drives the limiting plate 57 to move downward. The movement of the limiting plate 57 drives the clamping block 59 to move downward. After the clamping block 59 moves, it no longer contacts the seal. After the limiting plate 57 moves, the first torsion spring drives the clamping plate 58 to rotate in the direction of the limiting plate 57 and contact the limiting plate 57. After the limiting plate 57 contacts the clamping plate 58, the limiting plate 57 is limited again. The rotation of the clamping plate 58 drives the inclined surface vertical rod 56 to move upward. The movement of the inclined surface vertical rod 56 drives the transmission inclined block 55 to move in the direction of the seal and eject the welded seal, so that the device resets to the initial state after welding is completed and ejects the welded seal, facilitating the taking and re-welding of the welded seal, improving the comfort when using the device and effectively improving the working efficiency.

[0033] Please refer to Figure 1 - Figure 8, on the basis of the above embodiments, in another embodiment of the present invention, a protection device for buffering the feeding device and a demolding device for cooling the fixture 52 are provided on the top of the operating table 1. Among them, the protection device includes: a hollow box 61, a sliding plate 62, a clamping plate 63, an arc 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 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 subjected to an outward pulling force before it is completely shaped after welding, resulting in the disconnection of the welded joint and ensuring the production quality.

[0034] The protection device further includes: a through rod 67, a connecting rod 68, a pressing rod 69 and a contact long rod 610. The through rod 67 is fixedly installed on the side of the arc plate 65 close to 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 long rod 610 slidably penetrates the inner and outer walls of the hollow box 61 and the driving device 51. The contact long rod 610 is fixedly connected to the sliding plate 62, which is convenient for reuse, reduces the resistance 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 plate 65 and the hollow box 61, and a third spring is provided between the sliding plate 62 and the hollow box 61. The sliding plate 62 is driven to reset by the third spring, and the arc plate 65 is driven to reset by the second spring 64.

[0036] The demolding device includes: an inflatable box 71, an air outlet pipe 72, a hollow pipe 73, a fixed block 74, a return rod 75, a sealing plate 76, a T-shaped block 77 and two sealing baffles 78. The inflatable 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 inflatable box 71. The hollow pipe 73 is fixedly installed on the surface of the inflatable box 71. The hollow pipe 73 is communicated with the inflatable box 71. The fixed block 74 is fixedly installed at the bottom of the inner wall of the driving device 51. The sealing plate 76 is slidably installed on the inner wall of the hollow pipe 73. One end of the return rod 75 is slidably installed on the side of the sealing plate 76 away from the inflatable box 71. The other end of the return rod 75 slidably penetrates the surface of the fixed block 74, so that the device will jet air at the welded joint after welding to quickly cool the welded joint, preventing the welding from failing due to demolding when the seal is not completely cooled, ensuring the stability of the work. The T-shaped block 77 is fixedly installed on the top of the return rod 75. Both sealing baffles 78 are slidably installed on the side of the sealing plate 76 away from the inflatable box 71. The T-shaped block 77 is fixedly connected to the sealing baffle 78, ensuring that the device will not be affected by resistance during inflation and increasing the cooling effect during jetting, improving the practicability of the device.

[0037] A fourth spring is provided between the looped rod 75 and the fixed block 74. The contact long rod 610 contacts the looped rod 75, and the looped rod 75 is driven to reset by the fourth spring.

[0038] During the operation of this embodiment: When the baffle 54 moves, it will contact the arc-shaped plate 65, and there will be mutual friction between the baffle 54 and the arc-shaped plate 65. Since the frictional force between the baffle 54 and the arc-shaped plate 65 increases, when the baffle 54 moves away from the fixture 52, it cannot move quickly, preventing the seal from being subjected to an outward pulling force before being fully shaped after welding, resulting in the disconnection of the welded joint and ensuring the production quality. The movement of the baffle 54 drives the connecting rod 68 to move towards the hollow box 61. The movement of the connecting rod 68 contacts the transmission rod 66. The movement of the connecting rod 68 drives the transmission rod 66 to move downward. The movement of the transmission rod 66 drives the sliding plate 62 to move downward. The movement of the sliding plate 62 drives the clamping plate 63 to move downward. After the clamping plate 63 moves, it no longer contacts the arc-shaped plate 65. After the arc-shaped plate 65 is no longer blocked by the clamping plate 63, it is reset by the second spring 64 and drives the arc-shaped plate 65 to move into the hollow box 61, so that after the baffle 54 retracts to the farthest position, the arc-shaped plate 65 no longer contacts the baffle 54, and the baffle 54 will not be blocked during the next processing, improving the work efficiency. When the connecting rod 68 moves towards the fixture 52, it drives the extrusion rod 69 to move towards the fixture 52. The movement of the extrusion rod 69 drives the penetrating rod 67 to move towards the arc-shaped plate 65. The movement of the penetrating rod 67 drives the arc-shaped plate 65 to move away from the inside of the hollow box 61. After the arc-shaped plate 65 moves, it is reset by the third spring and drives the sliding plate 62 to move upward. The movement of the sliding plate 62 drives the clamping plate 63 to move upward. After the clamping plate 63 moves, it limits the arc-shaped plate 65 again, facilitating reuse and reducing the resistance when the electric push rod 53 is pushed out, improving the service life of the device.

[0039] When the driving device 51 moves in the direction of approaching each other, the movement of the driving device 51 drives the fixed block 74 to move in the direction of the inflatable box 71. The movement of the fixed block 74 drives the movement of the looped rod 75, and the movement of the looped rod 75 drives the sealing plate 76 to move away from the inflatable box 71. After the welding is completed, the driving device 51 moves in the direction of moving away from each other. The movement of the driving device 51 drives the fixed block 74 to move in the direction of moving away from each other. The movement of the fixed block 74 drives the looped rod 75 to move in the direction of the inflatable box 71. The movement of the looped rod 75 drives the sealing plate 76 to move and squeeze the air inside the hollow tube 73 and the inflatable box 71 to be ejected through the air outlet pipe 72, so that after the welding is completed, the device will jet air at the welding point to quickly cool the welding point, prevent demolding when the seal is not completely cooled, resulting in welding failure, and ensure the stability of the work. The movement of the sliding plate 62 drives the contact long rod 610 to move downward. The movement of the contact long rod 610 will contact the looped rod 75 and drive the looped rod 75 to move downward. The movement of the looped rod 75 will drive the T-shaped block 77 to move downward. The movement of the T-shaped block 77 drives the sealing baffle 78 to move downward and coincide with the opening on the surface of the sealing plate 76, so that the sealing plate 76 can inhale air into the interior of the inflatable box 71 through the opening on the surface when inflating, and completely close when jetting air to increase the air pressure, ensuring that the device will not be affected by resistance when inflating and increasing the cooling effect when jetting air, and improving the practicability of the device.
