Description

Technical Field

[0001] This invention relates to the field of welding machine technology, and more specifically, to a welding machine for bonding sealing strips. Background Technology

[0002] Cars are equipped with sealing strips to seal gaps in the vehicle body, preventing wind, rain, dust, and noise from entering the car interior. Therefore, the sealing strips are required to have high sealing performance. Sealing strips are basically made of plastic injection molding. However, due to limitations such as injection molding process, many complex plastic sealing strips cannot be injection molded in one go and need to be heat-sealed and bonded at both ends using a welding machine.

[0003] Traditional welding machines consist of a heating element and left and right welding molds. During operation, it is necessary to manually insert both ends of each sealing strip into the left and right welding molds, move the left or right mold to make the ends of the sealing strips on the two molds fit together. Before this, it is also necessary to manually attach a small part of the sealing sheet for bonding to one end. After the sealing is fitted, the heating element is turned on to complete the melting operation.

[0004] Traditional welding machines have the following problems: the entire production process depends entirely on manual labor and has a low degree of automation. Summary of the Invention

[0005] This invention proposes a welding machine for bonding sealing strips, which solves the problems of low automation in traditional welding machines and the fact that the entire process depends on manual labor.

[0006] The technical solution of the present invention is as follows:

[0007] A welding machine for bonding sealing strips, used to weld the two ends of a sealing strip together via a sealing sheet, comprising:

[0008] Welding body;

[0009] A clamping assembly, disposed on the welding body, is used to clamp both ends of the sealing strip and place it within the welding body. The clamping assembly includes:

[0010] A first frame is movably mounted on the welding body, and after the first frame moves, it moves closer to or further away from the welding body;

[0011] Two semicircular rails are movably mounted on the first frame, and the two semicircular rails move closer to or further away from each other after they move.

[0012] A clamp is slidably mounted on the semi-circular rail and is used to clamp one end of the sealing strip. After the clamp slides, it is used to drive the two ends of the sealing strip closer to each other.

[0013] As a further technical solution, the clamp has a connecting part, and the clamp is slidably mounted on the semi-circular rail through the connecting part.

[0014] As a further technical solution, the connecting part has a sliding groove with an opening, and after the connecting part slides, the two openings correspond to each other, and it further includes:

[0015] The telescopic component is slidably disposed in the sliding groove. The telescopic component has telescopic ends. After the telescopic component extends or retracts, the two telescopic ends are used to clamp the sealing sheet.

[0016] As a further technical solution, the length direction of the sliding groove is parallel to the moving direction of the first frame.

[0017] As a further technical solution, it also includes:

[0018] The material storage channel is located on the welding body above the semi-circular rail. The material storage channel is used to store the sealing sheets sequentially from top to bottom. After the connecting part slides, the telescopic end moves closer to or away from the material storage channel.

[0019] As a further technical solution, the semicircular rail has a semicircular groove, and the connecting part is slidably disposed within the semicircular groove, further comprising:

[0020] An arc-shaped rack is disposed within the semi-circular groove;

[0021] The gear is rotatably connected to the connecting part and meshes with the arc-shaped rack. After the gear rotates, it drives the connecting part to slide.

[0022] As a further technical solution, the fixture includes:

[0023] The second frame has the connecting part, and the second frame is slidably mounted on the semi-circular rail through the connecting part;

[0024] Two semicircular clamps are movably mounted on the second frame, forming a clamping area between the two semicircular clamps. After the two semicircular clamps move, they abut against each other or cancel the abutment. The axial direction of the semicircular clamps is perpendicular to the axial direction of the semicircular rail.

[0025] As a further technical solution, it also includes:

[0026] A first heating mold is disposed on the welding body;

[0027] The second heating mold is movably mounted on the welding body. After the second heating mold moves, it moves closer to or further away from the first heating mold. A welding area is formed between the first heating mold and the second heating mold. After the first frame moves, the clamp is used to drive one end of the sealing strip into the welding area, and the telescopic member is used to drive the sealing sheet into the welding area.

[0028] As a further technical solution, it also includes:

[0029] A screw is rotatably mounted on the first frame, and the semi-circular rail also has a connecting block, which is threadedly connected to the screw.

[0030] The working principle and beneficial effects of this invention are as follows:

[0031] The working principle of this invention is as follows: The clamping assembly directly clamps the sealing strips arranged in sequence in the material box, replacing manual operation. It moves both ends of the sealing strips to a position that allows them to be directly installed into the mold inside the welding body under the action of the first frame, thereby improving the overall work progress and greatly saving labor costs. When using the clamping assembly, the first frame is first moved to allow the clamps to hold both ends of the sealing strips. After clamping, the clamps move closer to the two semi-circular rails and simultaneously move the clamps on the semi-circular rails to form a position that allows the sealing strips to be easily installed into the mold. Finally, the first frame is moved to install the sealing strips, and the welding body is controlled to work, completing the welding operation. Attached Figure Description

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1-7 As shown, this embodiment proposes a welding machine for bonding sealing strips, used to weld the two ends of the sealing strip 1 together through the sealing sheet 2, including:

[0043] 3. Welding body;

[0044] A clamping assembly 4 is disposed on the welding body 3 and is used to clamp both ends of the sealing strip 1 and place it inside the welding body 3. The clamping assembly 4 includes:

[0045] The first frame 41 is movably mounted on the welding body 3. After the first frame 41 moves, it moves closer to or further away from the welding body 3.

[0046] Two semicircular rails 42 are movably mounted on the first frame 41. After the two semicircular rails 42 move, they move closer to or further away from each other.

[0047] The clamp 43 is slidably disposed on the semi-circular rail 42 and is used to clamp one end of the sealing strip 1. After the clamp 43 slides, it is used to drive the two ends of the sealing strip 1 closer to each other.

[0048] In this embodiment, the working principle is as follows: The clamping assembly 4 directly clamps the sealing strips 1 arranged in sequence in the material box, replacing manual action. It moves both ends of the sealing strip 1 to a position that allows it to be directly installed in the mold inside the welding body 3 under the action of the first frame 41, thereby improving the overall work progress and greatly saving labor costs. When using the clamping assembly 4, the first frame 41 is first moved to allow the clamp 43 to clamp both ends of the sealing strip 1. After clamping, the clamps 43 on the two semi-circular rails 42 move closer to each other and move simultaneously to form a position where the sealing strip 1 can be easily installed in the mold, similar to the shape of a playground. The two ends of the sealing strip 1 are in a state that allows it to be directly clamped in the mold of the welding body 3. Finally, the first frame 41 is moved to install the sealing strip 1, and the welding body 3 is controlled to work to complete the welding operation.

[0049] Furthermore, the clamp 43 has a connecting portion 44, and the clamp 43 is slidably mounted on the semi-circular rail 42 via the connecting portion 44.

[0050] Furthermore, the connecting portion 44 has a sliding groove 45, the sliding groove 45 has an opening 46, and after the connecting portion 44 slides, the two openings 46 correspond to each other, and it also includes:

[0051] The telescopic component 5 is slidably disposed in the sliding groove 45. The telescopic component 5 has telescopic ends 51. After the telescopic component 5 is extended or retracted, the two telescopic ends 51 are used to clamp the sealing sheet 2.

[0052] Furthermore, the length direction of the sliding groove 45 is parallel to the moving direction of the first frame 41.

[0053] Furthermore, it also includes:

[0054] The material storage channel 6 is disposed on the welding body 3, located above the semi-circular rail 42. The material storage channel 6 is used to store the sealing sheet 2 sequentially from top to bottom. After the connecting part 44 slides, the telescopic end 51 moves closer to or away from the material storage channel 6.

[0055] In this embodiment, the working principle is as follows: The clamping assembly 4 directly clamps the sealing strips 1 arranged in sequence in the material box, replacing manual action. It moves both ends of the sealing strip 1 to a position that allows it to be directly installed in the mold inside the welding body 3 under the action of the first frame 41, thereby improving the overall work progress and greatly saving labor costs. When using the clamping assembly 4, the first frame 41 is first moved to allow the clamp 43 to clamp both ends of the sealing strip 1. After clamping, the clamps 43 on the two semi-circular rails 42 move closer to each other and move simultaneously to form a position where the sealing strip 1 can be easily installed in the mold, similar to the shape of a playground. The two ends of the sealing strip 1 are in a state that allows it to be directly clamped in the mold of the welding body 3. Finally, the first frame 41 is moved to install the sealing strip 1, and the welding body 3 is controlled to work to complete the welding operation.

[0056] Furthermore, the semicircular rail 42 has a semicircular groove 47, and the connecting part 44 is slidably disposed within the semicircular groove 47, and further includes:

[0057] Arc-shaped rack 7, wherein the arc-shaped rack 7 is disposed within the semi-circular groove 47;

[0058] Gear 8 is rotatably connected to the connecting part 44 and meshes with the arc-shaped rack 7. After the gear 8 rotates, it drives the connecting part 44 to slide.

[0059] In this embodiment, in order to facilitate the sliding of the drive connection part 44 on the semi-circular rail 42 and to avoid too many structures being set outside the semi-circular rail 42, which could easily affect the working process, the semi-circular rail 42 is designed to have a semi-circular groove 47. The connection part 44, through the meshing of the gear 8 rotatably connected to it with the arc-shaped rack 7 in the semi-circular groove 47, realizes that after the gear 8 rotates, the connection part 44 slides along the semi-circular groove 47, thereby stably driving the clamp 43 to move, so that the sealing strip 1 can be easily installed in the welding body 3 later.

[0060] Furthermore, the clamp 43 includes:

[0061] The second frame 48 has the connecting part 44 and is slidably mounted on the semi-circular rail 42 through the connecting part 44.

[0062] Two semicircular clamps 49 are movably mounted on the second frame 48, forming a clamping area 410 between the two semicircular clamps 49. After the two semicircular clamps 49 move, they abut against each other or cancel the abutment. The axial direction of the semicircular clamps 49 is perpendicular to the axial direction of the semicircular rail 42.

[0063] In this embodiment, in order to accommodate sealing strips 1 of different specifications and to facilitate clamping both ends of them with clamp 43, clamp 43 is composed of a second frame 48 and two semi-circular clamps 49. The second frame 48 provides stable support for the semi-circular clamps 49 and is connected to the connecting part 44. The two semi-circular clamps 49 move closer or further away from each other on the second frame 48 and perform clamping operations on both sides of one end of the sealing strip 1, clamping it in the clamping area 410. Since the sealing strip 1 is made of plastic, even if the diameter of the sealing strip 1 is too large, it can be stably clamped by clamp 43.

[0064] Furthermore, it also includes:

[0065] A first heating mold 9 is disposed on the welding body 3;

[0066] The second heating mold 10 is movably mounted on the welding body 3. After the second heating mold 10 moves, it approaches or moves away from the first heating mold 9. A welding area 11 is formed between the first heating mold 9 and the second heating mold 10. After the first frame 41 moves, the clamp 43 is used to drive one end of the sealing strip 1 into the welding area 11, and the telescopic member 5 is used to drive the sealing sheet 2 into the welding area 11.

[0067] In this embodiment, in order to accommodate sealing strips 1 of different specifications and to facilitate clamping both ends of them with clamp 43, clamp 43 is composed of a second frame 48 and two semi-circular clamps 49. The second frame 48 provides stable support for the semi-circular clamps 49 and is connected to the connecting part 44. The two semi-circular clamps 49 move closer or further away from each other on the second frame 48 and perform clamping operations on both sides of one end of the sealing strip 1, clamping it in the clamping area 410. Since the sealing strip 1 is made of plastic, even if the diameter of the sealing strip 1 is too large, it can be stably clamped by clamp 43.

[0068] Furthermore, it also includes:

[0069] The screw 12 is rotatably mounted on the first frame 41, and the semi-circular rail 42 also has a connecting block 411, which is threadedly connected to the screw 12.

[0070] In this embodiment, in order to stably achieve the movement effect of the two semicircular rails 42 moving closer or further apart on the first frame 41, the screw 12 is rotatably installed on the first frame 41 using the principle of screw thread and nut. The screw 12 is driven by a motor and threadedly connected to the screw 12 through the connecting block 411411 of the semicircular rail 42. The screw connection of the two semicircular rails 42 is designed to have opposite directions of rotation, which can achieve this.

[0071] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
