Description

Technical Field

[0001] This utility model belongs to the field of welding strip straightening technology, and specifically relates to a welding strip straightening device. Background Technology

[0002] Welding strips are strip-shaped metal materials used for electrical or structural connections in welding processes, and they play a crucial role, especially in photovoltaic modules.

[0003] After processing, the welding strip needs to be rolled up for packaging, transportation, and storage. This means that the welding strip needs to be straightened before use. Because the welding strip is curved, it is difficult to reverse and reset it during straightening, resulting in poor straightening effect.

[0004] Therefore, a welding strip straightening device is proposed. Summary of the Invention

[0005] This utility model provides a welding strip straightening device, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a welding strip straightening device, including a frame and a cover on top of it; a lower roller rotating on the outer wall of the frame; and a welding strip pressure assembly on the frame and the cover. The welding strip pressure assembly includes: a screw threadedly connected to the top of the cover; an extrusion plate rotating at the bottom of the screw; an adjustment platform located below the extrusion plate; a guide post on the top of the adjustment platform, passing through the extrusion plate; a connecting plate inside the adjustment platform; a spring between the connecting plate and the extrusion plate; an upper roller rotating on the outer wall of the adjustment platform, with the lower and upper rollers arranged alternately; and a spring preload adjustment assembly on the adjustment platform.

[0007] Furthermore, the spring preload adjustment assembly includes: a cover plate disposed on the outer wall of the other side of the adjustment platform; a screw rod II threaded through and screwed onto the outer wall of the cover plate; a horizontal engagement platform rotating at one end of the screw rod II; a vertical engagement platform disposed at the bottom of the connecting plate; an inner cavity opened inside the adjustment platform; and a turntable disposed at the other end of the screw rod II.

[0008] Furthermore, the outer wall of the frame is provided with an adjustment groove for sliding the extrusion plate and the adjustment table, and the cross-section of the extrusion plate and the adjustment table is I-shaped.

[0009] By adopting the above technical solution, the "I" shape is used to give it a limiting ability, ensuring that the extrusion plate and the adjustment table move up and down along the frame.

[0010] Furthermore, a welding strip passes between the lower roller and the upper roller;

[0011] Furthermore, a second spring is embedded in the bottom of the adjustment groove, and a pressure sensor is installed at the bottom end of the second spring;

[0012] By adopting the above technical solution, the spring and pressure sensor can be used to compress the spring and trigger the protection mechanism when overloaded, avoiding excessive extrusion and deformation of the welding strip. This can achieve dynamic compensation for material fluctuations and avoid mechanical hard contact damage to the surface.

[0013] Furthermore, the guide post has a T-shaped structure;

[0014] By adopting the above technical solution, the T-shaped guide column can be used to limit the movement, thereby preventing the extrusion plate from detaching from the adjustment table and ensuring that there is a limited movement space between the extrusion plate and the adjustment table.

[0015] Furthermore, the outer walls of the horizontal and vertical mating platforms facing each other are provided with matching inclined surfaces, and both the horizontal and vertical mating platforms are slidably connected to the inner cavity.

[0016] By adopting the above technical solution, the horizontal and vertical mating platforms are relatively displaced when they are squeezed due to the matching inclined surfaces, and the horizontal and vertical mating platforms slide linearly through the sliding connection.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention, through the cooperation of the welding strip pressure application component and the spring preload adjustment component, can not only adjust the preload of the spring to adjust the pressure applied to the welding strip and adapt to the straightening requirements of welding strips of different thicknesses and hardnesses, but also apply appropriate pressure to the welding strip. By using the staggered arrangement of the lower and upper rollers, the welding strip can be repeatedly bent in the reverse direction to eliminate internal stress and achieve the effective straightening effect of resetting the curled welding strip by reverse bending.

[0019] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Reference Figure 1-5This utility model embodiment proposes a welding strip straightening device, including a frame 1. A cover 2 is bolted to the top of the frame 1, and three lower rollers 3 are rotatably connected at equal intervals on one side of the outer wall of the frame 1. A screw 41 from a welding strip pressure assembly 4 is threadedly connected to the top of the cover 2. An extrusion plate 42 is rotatably connected to the bottom end of the screw 41. An adjustment platform 43 is located below the extrusion plate 42. Four guide posts 44 are symmetrically arranged on the top of the adjustment platform 43. The guide posts 44 have a T-shaped structure, allowing the welding strip to be straightened. It has a limiting ability, thereby preventing the extrusion plate 42 from detaching from the adjusting table 43 and ensuring that there is a limited movement space between the extrusion plate 42 and the adjusting table 43. Four guide columns 44 pass through the extrusion plate 42. A connecting plate 45 is provided inside the adjusting table 43. A spring 46 is fixedly connected to the top center of the connecting plate 45 and the bottom center of the extrusion plate 42. A through hole is opened at the top of the adjusting table 43 near the outer side of the spring 46. An upper roller 47 is rotatably connected to one side of the outer wall of the adjusting table 43 near the upper position between the two lower rollers 3.

[0029] A cover plate 51 of the spring preload adjustment assembly 5 is provided on one side of the outer wall of the adjusting platform 43. A screw 52 is threadedly connected to one side of the outer wall of the cover plate 51. One end of the screw 52 is rotatably connected to a horizontal mating platform 53. A vertical mating platform 54 is provided at the bottom of the connecting plate 45. An inner cavity 55 is provided inside the adjusting platform 43 near the outer side of the connecting plate 45, the horizontal mating platform 53, and the vertical mating platform 54. The outer walls of the horizontal mating platform 53 and the vertical mating platform 54 facing each other are provided with matching inclined surfaces. The horizontal mating platform 53 and the vertical mating platform 54 are slidably connected to the inner cavity 55. Through the matching inclined surfaces, the horizontal mating platform 53 and the vertical mating platform 54 are relatively displaced when squeezed. The sliding connection allows the horizontal mating platform 53 and the vertical mating platform 54 to slide linearly. A turntable 56 is provided at the other end of the screw 52.

[0030] An adjustment groove 6 is provided on the outer wall of the frame 1, which allows the extrusion plate 42 and the adjustment table 43 to slide. The cross-section of the extrusion plate 42 and the adjustment table 43 is "I" shaped. The "I" shape provides a limiting ability, ensuring that the extrusion plate 42 and the adjustment table 43 move up and down along the frame 1. A welding strip 7 passes between the lower roller 3 and the upper roller 47. A second spring 8 is embedded in the bottom of the adjustment groove 6. A pressure sensor is provided at the bottom of the second spring 8. The second spring 8 and the pressure sensor can compress the second spring 8 to trigger the protection mechanism when overloaded, preventing the welding strip 7 from being excessively extruded and deformed. This can achieve dynamic compensation for material fluctuations and avoid mechanical hard contact damage to the surface.

[0031] The specific implementation method is as follows: When straightening the welding strip 7, the screw 41 is rotated and screwed into the machine cover 2. The bottom end of the screw 41 pushes the extrusion plate 42 to rise and fall. Under the guidance of the guide column 44, the adjustment table 43 moves synchronously and the upper roller 47 on the adjustment table 43 moves synchronously. The welding strip 7 is conveyed by the rotation of the lower roller 3 and the upper roller 47. The staggered arrangement of the lower roller 3 and the upper roller 47 can repeatedly bend the welding strip 7 in the opposite direction to eliminate internal stress.

[0032] To accommodate the straightening of welding strips 7 of different thicknesses, the preload of spring 46 can be adjusted using the spring preload adjustment component 5. Appropriate preload is applied to the welding strip 7. Specifically, rotating screw 52 causes one end of screw 52 to push the horizontal mating platform 53 to move horizontally in a straight line via the threaded connection between screw 52 and cover plate 51. Through the mating inclined surfaces, the horizontal mating platform 53 pushes the vertical mating platform 54 to move vertically in a straight line, thereby causing the connecting plate 45 and spring 46 to move upwards. This compresses or stretches spring 46 between the pressing plate 42 and connecting plate 45, thus adjusting the preload of spring 46. Adjusting the applied pressure can accommodate the needs of welding strips 7 of different thicknesses and hardnesses.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
