Description

Technical Field

[0001] The utility model relates to the technical field of welding strip processing, in particular to a welding strip rolling mechanism for preventing the welding strip from shrinking. Background Art

[0002] The welding ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the welding ribbon will directly affect the current collection efficiency of the photovoltaic module and have a great impact on the power of the photovoltaic module. The welding ribbon must be firmly welded in the process of connecting the battery cells in series to avoid the occurrence of false welding.

[0003] The welding strip is usually made by rolling copper wire through a calender. In the prior art, in the process of rolling the copper wire by most rolling mechanisms, when the annular pressing roller of the upper pressing roller is separated from the arc-shaped protrusion of the lower pressing roller, the copper wire immediately loses the force of the upper and lower pressing rollers, and the copper wire shrinks. The copper wire loses the forward conveying traction force, resulting in inconsistent intervals of the flattened sections, insufficient processing accuracy, and insufficient practicality. Therefore, it is necessary to redesign a welding strip rolling mechanism that can prevent the welding strip from shrinking in response to the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a welding strip rolling mechanism for preventing the welding strip from shrinking.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure is hinged on the base plate, is fixed with a backing pin on the interlocking structure, and an end of sliding panel withstands on the backing pin of interlocking structure.

[0007] Preferably, the lifting mechanism comprises a cylinder fixedly mounted on the bottom wall of the support frame, and the telescopic end of the cylinder is fixedly connected to the upper end surface of the connection frame.

[0008] Preferably, the elastic mechanism comprises a spring fixedly mounted on the outer wall of the prismatic rod, and two ends of the spring are elastically connected to the outer wall of the support plate and the inner wall of the arc block respectively.

[0009] Preferably, the limiting mechanism comprises a limiting rod fixedly installed inside the moving frame, and the limiting rod slides through the two moving sleeves.

[0010] Preferably, the connection mechanism comprises a connection rod fixedly mounted on the upper end surface of the moving sleeve, and the end of the connection rod is fixedly connected to the outer wall of the positioning frame.

[0011] Preferably, a plurality of anti-slip strips are fixedly mounted on the inner walls of the two clamping plates, and each of the anti-slip strips is made of rubber.

[0012] Beneficial effects of the utility model:

[0013] 1. By setting up components such as an extrusion plate, an arc block, a prismatic rod and a clamping plate, as the extrusion plate continues to move upward, the arc block is forced to drive the prismatic rod to move, so that the two prismatic rods can respectively drive the clamping plates on the same side to move, so that the two clamping plates can be brought close to each other and the copper wire can be clamped and fixed through multiple anti-slip strips to prevent the copper wire from shrinking.

[0014] 2. By setting up components such as a double-headed screw, a movable sleeve, a positioning frame and a positioning roller, the double-headed screw drives the two movable sleeves to move by cooperating with the limit rod, so that the two positioning frames can be close to each other, so that the two rotatably installed positioning rollers can position the copper wire during the wire feeding process, avoiding displacement and deviation of the copper wire during the wire feeding process, and preventing the calendering effect of the copper wire from being affected.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A welding strip rolling mechanism for preventing welding strip from shrinking comprises a bottom plate 1, a lower pressure roller 3 is rotatably installed on the upper end surface of the bottom plate 1 through a support frame 2, a connecting frame 5 is fixedly connected to the bottom wall of the support frame 2 through a lifting mechanism, the lifting mechanism comprises a cylinder 4 fixedly installed on the bottom wall of the support frame 2, the telescopic end of the cylinder 4 is fixedly connected to the upper end surface of the connecting frame 5, an upper pressure roller 6 is rotatably installed inside the connecting frame 5, two connecting rods 7 are fixedly installed on the upper end surface of the connecting frame 5, and extrusion plates 8 are fixedly installed on the outer walls of the two connecting rods 7, two prismatic rods 10 are slidably installed on the upper end surface of the bottom plate 1 through two support plates 9, and arc blocks 11 cooperating with the extrusion plates 8 on the same side are fixedly installed on the outer walls of the two prismatic rods 10.

[0023] The inner walls of the two arc blocks 11 are connected to the outer wall of the support plate 9 on the same side through an elastic mechanism. The elastic mechanism includes a spring 12 fixedly mounted on the outer wall of the prismatic rod 10. The two ends of the spring 12 are elastically connected to the outer wall of the support plate 9 and the inner wall of the arc block 11 respectively. A clamping plate 13 is fixedly mounted on the ends of the two prismatic rods 10. A plurality of anti-slip strips 14 are fixedly mounted on the inner walls of the two clamping plates 13. Each anti-slip strip 14 is made of rubber. The rubber material has good elasticity and softness, which enables it to form a closer contact between the surface and the object, thereby increasing friction and improving the friction coefficient.

[0024] A double-headed screw 16 is rotatably installed on the upper end surface of the base plate 1 through a moving frame 15, and a motor 17 connected to the double-headed screw 16 is fixedly installed on the outer wall of the moving frame 15. Two moving sleeves 19 are threadedly installed on the outer wall of the double-headed screw 16 through a limiting mechanism. The limiting mechanism includes a limiting rod 18 fixedly installed inside the moving frame 15, and the limiting rod 18 slides through the two moving sleeves 19. The limiting rod 18 can limit the two moving sleeves 19 so that the two moving sleeves 19 can only move axially along the outer wall of the double-headed screw 16. The upper end surfaces of the two moving sleeves 19 are fixedly connected with positioning frames 21 through a connecting mechanism. The connecting mechanism includes a connecting rod 20 fixedly installed on the upper end surface of the moving sleeve 19, and the end of the connecting rod 20 is fixedly connected to the outer wall of the positioning frame 21. Positioning rollers 22 are rotatably installed inside the two positioning frames 21.

[0025] When the utility model is used, in the process of the lower pressing roller 3 and the upper pressing roller 6 cooperating to calender the copper wire, the motor 17 can drive the double-headed screw 16 to rotate, and the double-headed screw 16 drives the two movable sleeves 19 to move by cooperating with the limit rod 18. At this time, the two movable sleeves 19 can respectively drive the positioning frame 21 to move by cooperating with the connecting rod 20, thereby making the two positioning frames 21 close to each other, so that the two rotatably installed positioning rollers 22 can position the copper wire during the wire feeding process, avoiding displacement and deviation of the copper wire during the wire feeding process, and preventing the copper wire from affecting the calendering effect;

[0026] When the cylinder 4 drives the upper pressure roller 6 to move upward through the connecting frame 5, the connecting frame 5 can drive the two extrusion plates 8 to move upward through the cooperation of the two connecting rods 7. At this time, the two extrusion plates 8 can make the slope of their outer walls contact the outer wall of the arc block 11. As the extrusion plate 8 continues to move upward, the arc block 11 is forced to drive the prismatic rod 10 to move and squeeze the spring 12, thereby allowing the two prismatic rods 10 to drive the clamping plates 13 on the same side to move respectively, so that the two clamping plates 13 can be close to each other and clamp the copper wire through multiple anti-slip strips 14 to prevent the copper wire from shrinking. Conversely, when the cylinder 4 drives the connecting frame 5 to descend, at this time, driven by the connecting rod 7, the extrusion plate 8 can gradually reduce the extrusion of the arc block 11, and then the spring 12 can release the elastic potential energy to drive the prismatic rod 10 to move, thereby allowing the two clamping plates 13 to move away from each other and release the clamping and fixation of the copper wire, so that the copper wire can continue to be fed.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
