Description

Technical Field

[0001] This application relates to the field of welding strip processing technology, and in particular to a welding strip rolling device. Background Technology

[0002] Currently, photovoltaic welding ribbons are usually made of composite materials. Composite materials are composed of two or more materials with different properties, which are combined to form materials with new properties at the macroscopic or microscopic level through physical or chemical methods. Composite welding ribbons usually use cladding composite materials, in which one material is clad on another material, such as copper-clad aluminum. The composite material is rolled to form welding ribbons that meet the required specifications.

[0003] In existing roll forming equipment, the composite material is first drawn into small-sized round filaments using a drawing die. These filaments are then rolled into the desired rectangular welding strip by a combination of upper and lower cylindrical pressure rollers with flat surfaces. However, due to the poor ductility of composite materials, improper adjustment of the upper and lower pressure rollers can easily affect product quality. For example, if the distance between the pressure rollers is too small or the levelness is insufficient, the composite material may deform significantly, potentially exposing the covering material and resulting in defective parts. Therefore, existing roll forming equipment requires high precision in roller assembly to ensure product quality, making manual adjustment difficult and requiring multiple adjustments. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a strip pressing device to achieve the technical effect of low assembly difficulty of the pressing rollers and ensuring the quality of the pressed products.

[0005] This application provides a strip pressing device, including a frame and a first pressing roller and a second pressing roller disposed on the frame;

[0006] The first pressure roller has at least one groove that is connected end to end along its circumference. The first pressure roller and the second pressure roller can rotate relative to each other so that the material passing through is squeezed in the groove to form a welding strip.

[0007] In one embodiment of the above-described welding strip rolling device,

[0008] There are at least two grooves, and the at least two grooves are arranged at intervals along the axial direction of the first pressure roller.

[0009] In one embodiment of the above-described welding strip rolling device,

[0010] The width and / or depth of each groove are different.

[0011] In one embodiment of the above-described welding strip rolling device,

[0012] The strip rolling device further includes a feeding guide mechanism, which includes a base with a guide groove for conveying material into the groove located between the first pressure roller and the second pressure roller. The conveying direction of the guide groove is perpendicular to the axial direction of the first pressure roller.

[0013] In one embodiment of the above-described welding strip rolling device,

[0014] The base includes a support member and a first stop and a second stop that are slidably mounted on the support member and can move closer to or further away from each other, with the gap between the first stop and the second stop forming the guide groove.

[0015] In one embodiment of the above-described welding strip rolling device,

[0016] The feeding guide mechanism also includes an adjusting member, on which the first stop and the second stop are sleeved. The adjusting member rotates to drive the first stop and the second stop to move along the axis of the adjusting member and in opposite directions. The axis of the adjusting member is perpendicular to the conveying direction of the guide groove.

[0017] In one embodiment of the above-described welding strip rolling device,

[0018] The support member is equipped with at least two limiting members, which are located on the opposite outer sides of the first stop and the second stop, respectively.

[0019] In one embodiment of the above-described welding strip rolling device,

[0020] A guide shaft is provided between the first stop, the second stop, and the limiting member, and the axial direction of the guide shaft is perpendicular to the conveying direction of the guide groove.

[0024] The strip rolling device further includes a drive mechanism, the base is mounted on the drive end of the drive mechanism, and the drive mechanism is configured to move the base so that the guide groove engages with any of the grooves.

[0025] The above-described one or more embodiments of this application have at least one or more of the following beneficial effects:

[0026] In implementing the technical solution of this application, by opening grooves along the circumference of the pressure roller, the material is positioned in the grooves during the rolling process, forming the required welding strip. Since the grooves of the first pressure roller can form a fixed rolling space with the second pressure roller, there is no need to repeatedly adjust the assembly gap and level between the pressure rollers, reducing the assembly difficulty of the pressure rollers and making it easy to operate. At the same time, the fixed rolling space formed by the grooves can prevent excessive pressure from causing large material deformation, reducing the possibility of exposed coating material, achieving precise calendering, and forming the welding strip with the target size and appearance, thus ensuring the product quality of the processed welding strip.

[0027] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0037] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0038] As described in the background art, existing roll forming devices use flat-surfaced pressure rollers to calender composite materials. However, they require a high level of assembly skill from the pressure rollers. Not only must the roller gap between the pressure rollers be appropriate to ensure the pressure intensity, but the relative levelness between the rollers must also be consistent to ensure the uniform thickness of the calendered weld strip. The levelness of the assembled pressure rollers directly affects the quality of the weld strip produced by roll forming. However, currently, manual assembly is used, which is difficult and requires multiple adjustments, making it hard to accurately guarantee the assembly precision. Based on this, this application proposes a weld strip roll forming device to solve the above problems.

[0039] See appendix Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a welding strip rolling device according to an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a first pressure roller according to an embodiment of this application. Figure 1 and Figure 2 As shown, in one or more embodiments, the welding strip pressing device of this application includes a frame 100 and a first pressure roller 200 and a second pressure roller 300 disposed on the frame 100. At least one end-to-end groove 201 is provided on the first pressure roller 200 along its circumference. The first pressure roller 200 and the second pressure roller 300 can rotate relative to each other so that the material passing through is squeezed within the groove 201 to form a welding strip. It should be understood that in this application, the first pressure roller 200 can be installed at any position on one side of the second pressure roller 300, such as above, below, or to the side. The figures are only schematic structures and do not represent a specific limitation on the installation position of the first pressure roller 200. It is sufficient that after the first pressure roller 200 and the second pressure roller 300 are installed, they can rotate relative to each other, that is, they can rotate simultaneously or only one of the pressure rollers can rotate. Furthermore, during relative rotation, the material is squeezed through the groove 201 between the first pressure roller 200 and the second pressure roller 300. It should also be understood that the figure only shows the important components related to this application, and other components of the welding strip pressing device, such as the driving device and control mechanism of the pressing roller, are omitted. These can be set according to the specific needs of the pressing device in actual use, and are not limited in this application.

[0040] An optional working process of the welding strip rolling device in this embodiment is as follows: When it is necessary to calender materials, such as composite materials, to form welding strips, the composite material is introduced into the groove 201 on the side of the first pressure roller 200 near the second pressure roller 300. This side can be set as the feeding end of the two pressure rollers. The first pressure roller 200 and the second pressure roller 300 are operated to rotate, driving the composite material in the groove 201 to move forward in the rotation direction and be extruded. After extrusion, the composite material is output from the discharge end of the first pressure roller 200 and the second pressure roller 300 to form a welding strip of the same size as the groove 201.

[0041] The welding strip rolling device of this application embodiment, by opening a groove 201 along its circumference on the pressure roller, positions the material within the groove 201 during the rolling process, so as to form the required welding strip. Since the groove 201 of the first pressure roller 200 can form a fixed rolling space with the second pressure roller 300, there is no need to repeatedly adjust the assembly gap and level between the pressure rollers, which reduces the assembly difficulty of the pressure rollers and makes it easy to operate. At the same time, the fixed rolling space formed by the groove 201 can prevent excessive pressure from causing large material deformation, reduce the possibility of exposed coating material, achieve precise rolling, and form the welding strip with the target size and appearance, thus ensuring the product quality of the processed welding strip.

[0042] In one implementation, reference Figure 1 and Figure 2 There are at least two grooves 201, and at least two grooves 201 are arranged at intervals along the axial direction of the first pressure roller 200, that is, multiple grooves 201 are set. When the first pressure roller 200 and the second pressure roller 300 rotate relative to each other, multiple grooves 201 can simultaneously extrude the material to generate multiple welding strips. Alternatively, welding strips of different specifications can be generated by extruding by setting grooves 201 of different specifications.

[0043] In one possible implementation, refer to Figure 2 Each groove 201 can be set with different widths, different depths, or both widths and depths, to meet the production requirements of welding strips of various specifications and appearances.

[0044] In one possible implementation, refer to Figure 2 The grooves 201 arranged along the axial direction of the first pressure roller 200 can be arranged in a gradually decreasing or gradually increasing manner to facilitate finding the corresponding groove 201 during the calendering operation.

[0045] In one implementation, reference Figure 3The welding strip roller pressing device of this application also includes a feeding guide mechanism 400. The feeding guide mechanism 400 includes a base 401 with a guide groove 402. The guide groove 402 is used to convey material into the groove 201 located between the first pressure roller 200 and the second pressure roller 300. The conveying direction of the guide groove 402 is perpendicular to the axial direction of the first pressure roller 200. By setting the feeding guide mechanism 400, the material can smoothly enter the groove 201 according to the grooving direction of the groove 201, realizing precise directional feeding, ensuring the accuracy of the material extrusion direction, and thus improving the extrusion production quality. At the same time, by setting the conveying direction of the guide groove 402 to be perpendicular to the axial direction of the first pressure roller 200, the accuracy of the feeding direction can be further improved, so that it is accurately aligned with the groove 201 where the extrusion work is to be carried out.

[0046] In one possible implementation, refer to Figure 3 and Figure 4 The base 401 includes a support member 4011 and a first stop 4012 and a second stop 4013 slidably mounted on the support member 4011 and capable of moving closer or further apart from each other. The gap between the first stop 4012 and the second stop 4013 forms a guide groove 402. By setting the first stop 4012 and the second stop 4013, which are relatively adjustable, guide grooves 402 of different widths can be formed to accommodate materials of different widths entering the groove 201. This eliminates the need to pre-draw the material into small-sized round wires using a wire drawing die before extrusion, saving material processing steps and avoiding potential damage to the composite material from the wire drawing die, thereby improving the efficiency and quality of welding strip processing.

[0047] In one possible implementation, refer to Figure 3 and Figure 4 The feeding guide mechanism 400 also includes an adjusting member 403. A first stop 4012 and a second stop 4013 are sleeved on the adjusting member 403. The adjusting member 403 rotates, causing the first stop 4012 and the second stop 4013 to move along the axis of the adjusting member 403 and in opposite directions. The axis of the adjusting member 403 is perpendicular to the conveying direction of the guide groove 402. By adjusting the member 403, the gap between the first stop 4012 and the second stop 4013 is adjusted, thereby forming guide grooves 402 of different widths.

[0048] Specifically, the adjusting component 403 includes an adjusting rod 4031 and a handle 4032. The handle 4032 is located at one end of the adjusting rod 4031. The adjusting rod 4031 passes through a first stop 4012 and a second stop 4013. The adjusting rod 4031 has two sections of threads in opposite directions: a left-handed thread and a right-handed thread. The first stop 4012 is located on the left-handed thread, and the second stop 4013 is located on the right-handed thread (the two can also be interchanged). The first stop 4012 and the second stop 4013 respectively mate with these two sections of threads. When the adjusting rod 4031 rotates, the two... The difference in the direction of the thread segments causes the first stop 4012 and the second stop 4013 to move in opposite directions. The handle 4032 is used to rotate the adjusting rod 4031. For example, when in use, rotating the handle 4032 clockwise moves the second stop 4013 on the right-hand thread to the right and the first stop 4012 on the left-hand thread to the left, causing them to move away from each other and widening the guide groove 402. Rotating the handle 4032 counterclockwise moves the second stop 4013 on the right-hand thread to the left and the first stop 4012 on the left-hand thread to the right, causing them to move closer to each other and narrowing the guide groove 402.

[0049] In one possible implementation, refer to Figure 3 and Figure 4 At least two limiting members 404 are installed on the support member 4011. The at least two limiting members 404 are located on the opposite outer sides of the first stop 4012 and the second stop 4013, respectively. The limiting members 404 are used to limit the distance between the first stop 4012 and the second stop 4013 to be too wide, so as to prevent the first stop 4012 and the second stop 4013 from leaving the working range.

[0050] In one possible implementation, refer to Figure 3 and Figure 4 A guide shaft 405 is provided between the first stop 4012, the second stop 4013 and the limiting member 404. The axis of the guide shaft 405 is perpendicular to the conveying direction of the guide groove 402. Specifically, the guide shaft 405 can be respectively set on both sides of the adjusting member 403 to ensure the balance of the entire mechanism. By setting the guide shaft 405, it can be ensured that the moving direction of the first stop 4012 and the second stop 4013 is always perpendicular to the conveying direction of the guide groove 402 and maintains a horizontal state with each other. At the same time, it can also ensure that the width of the formed guide groove 402 is consistent from front to back, ensuring reliable material conveying.

[0051] In one possible implementation, refer to Figure 3 and Figure 4The first stop 4012 and the second stop 4013 are respectively provided with extensions 406 at one end near the first pressure roller 200 along the conveying direction perpendicular to the guide groove 402. The extensions 406 are provided on both sides of the guide groove 402. By providing extensions 406 at one end of the two stops, the material about to enter the pressure roller can be prevented from running out. At the position where the feeding guide mechanism 400 is close to the two pressure rollers, the material may run out due to the slow rolling speed of the pressure rollers or the fast feeding of the guide groove 402. By increasing the depth of the guide groove 402 at this point by extending the extensions 406, this situation can be prevented.

[0052] In one possible implementation, refer to Figure 3 and Figure 4 The welding strip rolling device also includes a drive mechanism. A base 401 is mounted on the drive end of the drive mechanism, which is configured to move the base 401 so that the guide trough 402 aligns with any groove 201. Since the first pressure roller 200 may have multiple grooves 201, when producing welding strips of different specifications, the material may need to be rolled through different grooves 201. Therefore, by driving the base 401 to move horizontally or vertically, the discharge end of the guide trough 402 is aligned with the required groove 201, achieving precise feeding. Specifically, the drive mechanism can employ a combination of a servo module and a cylinder to move the base 401 in the same direction as or perpendicular to the conveying direction of the guide trough 402. Furthermore, the entire feeding guide mechanism 400 can be movably mounted on the worktable 500. The worktable 500 can be fixed or an adjustable height and position support device, used to support the entire feeding guide mechanism 400 and to support the feeding guide mechanism 400 at a suitable position that aligns with the feeding positions of the first pressure roller 200 and the second pressure roller 300, so that the material can be guided into the corresponding groove 201 through the guide groove 402.

[0053] Based on the above implementation methods, refer to Figures 1-4 An optional working process of the welding strip rolling device in this embodiment is as follows: Select the groove 201 corresponding to the welding strip of the required size; drive the feeding guide mechanism 400 to move so that the discharge end of the guide groove 402 of the feeding guide mechanism 400 corresponds to the selected groove 201; adjust the gap between the first stop 4012 and the second stop 4013 by adjusting the adjusting member 403 so that the width of the guide groove 402 is consistent with the width of the selected groove 201; put the raw material into the adjusted guide groove 402 and pull it into the corresponding groove 201 through the guide groove 402, such as an aluminum-clad copper composite material for making welding strips; control the first pressure roller 200 and / or the second pressure roller 300 to rotate, and squeeze the material passing between the two along the groove 201 to form a welding strip of the required size.
