Description

Technical Field

[0001] The present invention relates to the technical field of welding ribbon processing, and in particular to photovoltaic welding ribbon processing equipment and a rolling mechanism thereof. Background Art

[0002] During the production process of welding strips, because the welding strips are made of multiple welding wires that are crisscrossed, welding spots are formed when two intersecting welding wires are welded together. Since the welding spots are superimposed by two welding wires, the thickness will be higher than the thickness of a single layer of welding wire. In order to ensure the flatness of the welding strip, it is only necessary to flatten the welding spots at the intersection, while other positions do not need to be flattened. Patent CN202023341363.1 discloses a welding strip flattening device, which is provided with a protrusion on at least one of the first pressing roller and the second pressing roller. When the welding strip passes through the gap between the first pressing roller and the second pressing roller, the welding spots on the upper part of the welding strip are flattened by the protrusion. However, the device has great limitations and cannot adjust the area range of the welding strip flattening according to actual needs. Summary of the Invention

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0018] (1) In the welding ribbon rolling mechanism proposed in the embodiment of the present application, the first protrusion and the second protrusion squeeze the welding ribbon entering the first gap. When the adjusting member drives the second roller to move axially, or the adjusting member drives the second roller to rotate about the axis, the length of the second protrusion contacting the welding ribbon changes, causing the length of the welding ribbon squeezed to change, thereby achieving adjustable area of ​​the welding ribbon squeezed. The adjusting member can be a handwheel or a handle, so that the user can grasp the adjusting member to move the second roller axially, or rotate the adjusting member to rotate the second roller about the axis.

[0019] (2) The welding strip rolling mechanism proposed in the embodiment of the present application has an arc-shaped longitudinal cross-section of the first protrusion and the longitudinal cross-section of the second protrusion. The adjusting member drives the second roller to rotate around the axis, and the overlapping length of the projection surface of the second protrusion in the vertical direction with the first protrusion changes, thereby achieving adjustable area of ​​the welding strip being squeezed.

[0020] (3) In the welding strip rolling mechanism proposed in the embodiment of the present application, when the transverse cross-section of the second protrusion is wavy, the adjusting member drives the second roller to move axially, and the length of the wavy second protrusion in contact with the welding strip changes, thereby changing the area where the welding strip is squeezed.

[0021] (4) The welding strip rolling mechanism proposed in the embodiment of the present application changes the position of the movable plate in the through groove by changing the distance that the movable rod extends out of the top plate. Since the end of the first roller is inserted into the movable plate, the height of the first roller is adjusted. By changing the distance between the first roller and the second roller, the requirements of different degrees of flattening of the welding strip are met.

[0022] (5) In the photovoltaic welding ribbon processing equipment proposed in the embodiment of the present application, any group of cutting components of the welding ribbon cutting mechanism is located between two groups of clamping jaw components. After the welding ribbon rolling mechanism flattens the welding ribbon, the horizontal driving member drives the vertical driving member to move along the support beam to the flattening mechanism. The vertical driving member drives the connecting plate to move in the vertical direction, so that the clamping jaw component approaches the welding ribbon and clamps the welding ribbon. Then the vertical driving member drives the connecting plate to move in the opposite vertical direction. The horizontal driving member drives the vertical driving member to move along the support beam 1 to the turntable. The cutting component cuts the welding ribbon. The n groups of cutting components cut the welding ribbon into n+1 parts. The clamping jaw components on both sides of the cutting component clamp the welding ribbon and place the welding ribbon on the battery cell, so as to realize the requirement of placing multiple welding ribbons on the battery cell at the same time and improve work efficiency.

[0023] (6) In the photovoltaic welding ribbon processing equipment proposed in the embodiment of the present application, the two sets of first cutters are respectively connected to a third driving member. When the welding ribbon needs to be cut, the third driving member drives the two sets of first cutters to move toward each other, thereby cutting the welding ribbon. The second driving member and the third driving member can be a cylinder, a hydraulic cylinder, or a motor. The protrusions are arranged in an interlaced manner with the protrusions on the other set of first cutters. When the third driving member drives the two sets of first cutters to move toward each other, the blades on one set of protrusions can contact the blades on the other set of protrusions, thereby cutting the welding ribbon.

[0037] Example 1

[0038] Combined with attachment Figure 1-10The welding ribbon rolling mechanism of this embodiment includes a first frame 1, a first roller 2, and a second roller 3. The first roller 2 and the second roller 3 are mounted parallel to the first frame 1. The first roller 2 is provided with a first protrusion 21, and the second roller 3 is provided with a second protrusion 31. A first gap is defined between the first protrusion 21 and the second protrusion 31 for the welding ribbon 9 to pass through. At an elevation angle, the vertical projection of the second protrusion 31 partially overlaps with the first protrusion 21. The second roller 3 is connected to an adjustment member that drives the second roller 3 to move axially or rotate about its axis to change the length of contact between the second protrusion 31 and the welding ribbon 9. The first protrusion 21 and the second protrusion 31 squeeze the welding ribbon 9 that enters the first gap. When the adjustment member drives the second roller 3 to move axially or rotate about its axis, the length of contact between the second protrusion 31 and the welding ribbon 9 changes, thereby changing the length of the welding ribbon 9 squeezed, thereby achieving adjustable squeezing area of ​​the welding ribbon 9. The adjusting member may be a hand wheel or a handle, so that the user can hold the adjusting member to move the second roller 3 axially, or rotate the adjusting member to rotate the second roller 3 around the axis.

[0039] Example 2

[0040] Combined with attachment Figure 1-10 Compared to the technical solution of Example 1, the welding ribbon rolling mechanism of this embodiment can be improved as follows: the first protrusion 21 is arranged around the outer peripheral wall of the first roller 2, and the second protrusion 31 is arranged around the outer peripheral wall of the second roller 3. The longitudinal cross-sections of the first protrusion 21 and the second protrusion 31 are both arc-shaped. The adjusting member drives the second roller 3 to rotate about the axis. The arc center angle of the first protrusion 21 is 120-200°, and the arc center angle of the second protrusion 31 is also 120-200°. The longitudinal cross-section in this embodiment refers to the cross-section of the first protrusion 21 and the second protrusion 31 in the vertical direction. When the adjusting member drives the second roller 3 to rotate about the axis, the length of the vertical projection of the second protrusion 31 overlapping with the first protrusion 21 changes, thereby achieving adjustable area of ​​compression of the welding ribbon 9. In this embodiment, the arc center angle of the first convex portion 21 and the arc center angle of the second convex portion 31 are both 180°. In other embodiments, the arc center angle of the first convex portion 21 and the arc center angle of the second convex portion 31 can be 120°, 150°, or 200°.

[0041] Example 3

[0042] Combined with attachment Figure 1-10Compared with the technical solutions of Example 1 or 2, the welding strip rolling mechanism of this embodiment can be improved as follows: the second protrusions 31 are distributed at intervals along the axial direction of the second roller 3, the transverse cross-section of the second protrusion 31 is wavy, the adjusting member drives the second roller 3 to move axially, the first protrusion 21 is arranged around the outer peripheral wall of the first roller 2, and the longitudinal cross-section of the first protrusion 21 is arc-shaped, and the arc center angle of the first protrusion 21 is 120~360°.

[0043] Problem Solved and Technical Effect: The transverse cross-section in this embodiment refers to the horizontal cross-section of the first and second protrusions 21 and 31. Because the conveying path of the welding ribbon 9 is fixed, when the adjustment member drives the second roller 3 to move axially, the length of the wavy second protrusion 31 in contact with the welding ribbon 9 changes, thereby changing the area of ​​the welding ribbon 9 squeezed. When the arc center angle of the first protrusion 21 is 360°, the first protrusion 21 is arranged around the outer peripheral wall of the first roller 2.

[0044] Example 4

[0045] Combined with attachment Figure 1-10 Compared with any one of the technical solutions in Examples 1-3, the welding strip rolling mechanism of this embodiment can be improved as follows: it also includes a driving component 4, the driving component 4 includes a first driving member 41, a first gear 42 and a second gear 43, the first frame 1 includes a top plate 11 and side plates 12 arranged on both sides of the top plate 11, the first roller 2 and the second roller 3 are both movably mounted on the side plates 12, the side plates 12 are provided with a first through hole and a second through hole, the first roller 2 is connected to the first gear 42 through the first through hole, the second roller 3 is connected to the second gear 43 through the second through hole, and the second gear 43 is respectively engaged with the first gear 42 and the first driving member 41.

[0046] The second roller 3 is rotatably or slidably mounted on the side plate 12. The first driving member 41 drives the second gear 43 to rotate, and the second gear 43 drives the first gear 42 to rotate synchronously. When the user holds the adjusting member to move the second roller 3 axially, or rotates the adjusting member to rotate the second roller 3 around the axis, it is necessary to first separate the first gear 42 from the first roller 2. The outer periphery of the first roller 2 is provided with a latching protrusion, and the first gear 42 is provided with a latching groove that cooperates with the latching protrusion, so that the first roller 2 and the first gear 42 are detachably connected. This prevents the second roller 3 from affecting the first roller 2 during movement. The second roller 3 and the second gear 43 can also be detachably connected. After the length of the second protrusion 31 contacting the welding strip 9 is adjusted, the first gear 42 is re-sleeved on the first roller 2 so that the first gear 42 and the second gear 43 are meshed. When the longitudinal cross-sections of the first protrusion 21 and the second protrusion 31 are both arc-shaped, the adjusting member can also be connected to the first roller 2. The user can grasp the adjusting member to move the first roller 2 axially, or rotate the adjusting member to rotate the first roller 2 about its axis. The output end of the first driving member 41 is provided with a transmission gear 44, which meshes with the second gear 43.

By changing the distance that the moving rod 51 extends out of the top plate 11, the position of the moving plate 52 in the through groove 121 is changed. Since the end of the first roller 2 is passed through the moving plate 52, the height of the first roller 2 is adjusted. By changing the distance between the first roller 2 and the second roller 3, the requirements for different degrees of flattening of the welding strip 9 are met.

The ribbon 9 rolling mechanism, wire cutting mechanism 8, and ribbon 9 transfer and cutting mechanism 7 are sequentially mounted on the mounting base 6 in the direction of conveyance of the ribbon 9. The ribbon 9 rolling mechanism flattens the ribbon 9, the wire cutting mechanism 8 cuts the flattened ribbon 9, and the ribbon 9 transfer and cutting mechanism 7 moves to the wire cutting mechanism 8 to clamp the cut ribbon 9 to the welding turntable.

[0051] Example 7

[0052] Combined with attachment Figure 1-10 Compared with any one of the technical solutions in Examples 1-6, the photovoltaic welding ribbon processing equipment of this embodiment can be improved as follows: the cutting mechanism 7 includes a support beam 71, a horizontal driving member 72, a vertical driving member 73, a connecting plate 74, at least two groups of clamping jaw assemblies 75 and at least one group of cutting assembly 76, the horizontal driving member 72 is coaxially mounted on the support beam 71, the horizontal driving member 72 drives the vertical driving member 73 to move in the horizontal direction, the vertical driving member 73 drives the connecting plate 74 to move in the vertical direction, the clamping jaw assembly 75 and the cutting assembly 76 are both mounted on the connecting plate 74, and the cutting assembly 76 is located between the two groups of clamping jaw assemblies 75.

[0053] Any set of cutting components 76 of the welding ribbon 9 cutting mechanism 7 is located between two sets of clamping jaw components 75. After the welding ribbon 9 rolling mechanism flattens the welding ribbon 9, the horizontal drive member 72 drives the vertical drive member 73 to move along the support beam 71 to the flattening mechanism. The vertical drive member 73 drives the connecting plate 74 to move in the vertical direction, so that the clamping jaw component 75 approaches the welding ribbon 9 and clamps the welding ribbon 9. Then the vertical drive member 73 drives the connecting plate 74 to move in the opposite vertical direction. The horizontal drive member 72 drives the vertical drive member 73 to move along the support beam 711 to the turntable. The cutting components 76 cut the welding ribbon 9. The n sets of cutting components 76 cut the welding ribbon 9 into n+1 parts. The clamping jaw components 75 on both sides of the cutting components 76 clamp the welding ribbon 9 and place the welding ribbon 9 on the battery cell, realizing the requirement of placing multiple welding ribbons 9 on the battery cell at the same time, thereby improving work efficiency. The horizontal drive member 72 and the vertical drive member 73 can be motors or linear stepping motors. The support beam 71 is mounted on the mounting base 6 via a column.

[0054] Example 8

[0055] Combined with attachment Figure 1-10The photovoltaic ribbon processing equipment of this embodiment, compared to any of the technical solutions of Examples 1-7, can be improved as follows: the clamping jaw 754 assembly 75 includes a second driving member, a first support plate 751, a connecting rod 752, and multiple clamping groups. The first support plate 751 is connected to the connecting plate 74. The clamping group includes a clamping rod 753 and a clamping jaw 754. One end of the clamping rod 753 is mounted on the first support plate 751, and one end of the clamping jaw 754 is mounted on the connecting rod 752. The clamping rod 753 is rotatably connected to the clamping jaw 754. When the second driving member drives the connecting rod 752 to move axially, the other end of the clamping jaw 754 movably abuts against the other end of the clamping rod 753. The clamping rod 753 has a protrusion that is rotatably connected to the clamping jaw 754. When it is necessary to clamp the welding strip 9, the second driving member drives the connecting rod 752 to move axially, and the connecting rod 752 drives the clamping jaw 754 to move synchronously. Since the part between the two ends of the clamping jaw 754 is rotationally connected to the part between the two ends of the clamping rod 753, when one end of the clamping jaw 754 is displaced, the other end of the clamping jaw 754 rotates around the connection until it abuts against the end of the clamping rod 753, clamping the welding strip 9 between the clamping rod 753 and the clamping jaw 754. When it is necessary to loosen the welding strip 9, just move in the opposite direction.

In the initial working position, the protrusions 7621 are staggered with the protrusions 7621 on the other group of first cutting knives 762.

[0058] The two sets of first cutters 762 are each connected to a third drive member.
