Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic welding ribbon take-up, and in particular to a photovoltaic welding ribbon take-up machine with an intelligent detection function. Background Art

[0002] Photovoltaic welding ribbon, also known as tinned copper ribbon, is a key part of solar photovoltaic modules. It is mainly used to connect photovoltaic cells and collect output current. It has good conductivity, weldability and corrosion resistance. High-quality photovoltaic welding ribbon can reduce resistance, improve current transmission efficiency, and reduce power loss. At the same time, it must have a certain mechanical strength to maintain a stable connection in various environments. The production process usually includes copper ribbon processing, tinning treatment and other links. The quality of each link in the production process must be strictly controlled to ensure that the performance meets the requirements.

[0003] The Chinese invention patent with application number 2016104158526 specifically discloses a photovoltaic welding tape winding machine, which has the characteristics of short production time, high efficiency, prevention of welding tape deformation, and convenient and simple operation. However, in the process of winding the photovoltaic welding tape, the above-mentioned equipment needs to move the wire arrangement mechanism at a uniform speed to guide so that the photovoltaic welding tape can be evenly wound on the winding drum, but does not consider the relaxation change of the photovoltaic welding tape from the midpoint of the winding drum to the end and then back to the midpoint. After the wire arrangement mechanism moves to both sides to form an oblique angle, the length of the photovoltaic welding tape increases and is tightened. When the wire arrangement mechanism moves to the farthest position and moves in the opposite direction, the length of the photovoltaic welding tape, the speed of the winding drum and the speed of the wire arrangement mechanism remain unchanged, but the inclination direction is reversed to relax the welding tape, resulting in an increase in the gap between the welding tapes on the winding drum and a chaotic arrangement, which increases the possibility of the welding tape being stuck in the gap, causing problems such as wire jumpers and greatly increases the probability of getting stuck.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a photovoltaic welding ribbon winding machine with intelligent detection function, which is used to solve the problem that the existing equipment does not take into account the relaxation change of the photovoltaic welding ribbon from the midpoint of the winding drum to the end and then back to the midpoint. The welding ribbon is easily loosened when the wire arrangement mechanism moves, resulting in an increase in the gap between the welding ribbons on the winding drum and a chaotic arrangement, which increases the possibility of getting stuck in the gap and causing the problem of wire jumping.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a photovoltaic welding ribbon take-up machine with intelligent detection function, comprising two frames and a support platform, the two frames are fixedly installed on one side of the support platform, a light rod cable arranger is fixedly installed between the two frames, a bracket 1 is fixedly connected to the top of the frame, a rotating shaft is arranged between the two brackets 1, and both ends of the rotating shaft are movably connected to the corresponding bracket 1 through bearings;

[0007] A rotating sleeve is fixed on the outer side of the rotating shaft, and a rotating plate is symmetrically fixedly connected to the outer side of the rotating sleeve. A receiving frame for placing a winding reel is fixedly installed on the end of the rotating plate away from the rotating sleeve by bolts, and a rotating reel is movably connected to one side of the receiving frame by a bearing, and a tensioning adjustment component is arranged on the top of the support platform.

[0010] Furthermore, a positioning rod is fixed to the inside of the supporting frame by spot welding, a positioning groove is opened on the inner wall of the supporting frame, a sliding seat is slidably connected to the outer side of the positioning rod, one end of the sliding seat is slidably connected in the positioning groove, one end of the sliding seat is fixedly connected to a vertical plate, the top of the vertical plate is fixedly connected to a frame, two frustum guide rollers are movably connected in the frame through bearings, and the two frustum guide rollers are placed in opposite directions.

[0011] Furthermore, both side walls of the vertical plate are fixedly connected with protrusions, the top of the support platform is symmetrically fixedly connected with guide plates, and the two guide plates are located between the sliders. The outer sides of the guide plates are inclined with drive grooves, and the protrusions are slidably connected in the corresponding drive grooves.

[0014] A swing groove is provided on the outer side of the swing rail, a rotating block is fixedly connected to one side of the rotating rod, and the rotating block is slidably connected in the swing groove.

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

[0018] When the present invention is in use, the installation directions of the two truncated cone guide rollers are exchanged, and the truncated cone guide rollers are driven to rise and fall reciprocally by the cooperation of the protrusion and the driving groove, so that the photovoltaic welding belt contacts the outer circle of the truncated cone guide rollers of different diameters, and the tension of the photovoltaic welding belt is adjusted.

[0019] This design makes up for the defect that the existing equipment does not take into account the relaxation change of the photovoltaic welding ribbon in the process of moving from the midpoint of the winding drum to the end and then returning to the midpoint. It can adjust the tension of the welding ribbon in real time during the movement of the wiring mechanism to prevent the welding ribbon from slackening, resulting in increased gaps between the welding ribbons on the winding drum, chaotic arrangement, and wire jumps, thereby improving the quality and stability of the photovoltaic welding ribbon winding.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: Figure 1-Figure 7 As shown, the photovoltaic welding ribbon take-up machine with intelligent detection function includes two frames 1 and a support platform 2. The two frames 1 are fixedly installed on one side of the support platform 2. A light rod cable arranger 3 is fixedly installed between the two frames 1. It should be noted that the light rod cable arranger 3 is an existing mechanism, which is mainly used to neatly arrange cables on the light rod. The light rod cable arranger 3 usually has a certain mechanical structure, can move smoothly along the light rod, and arrange cables and other materials in a specific position in an orderly manner. The working principle is generally to achieve accurate cable arrangement through cooperation with the light rod and the internal transmission mechanism;

[0031] A high-speed camera is arranged on the inner side of the polished rod arranging device 3. By installing the high-speed camera to shoot the winding process in real time, the high-speed camera can capture the subtle movements and changes of the photovoltaic welding ribbon during the winding process. By analyzing the captured images, it can be detected whether the photovoltaic welding ribbon vibrates, and the edge contour of the photovoltaic welding ribbon can be identified by using the image processing algorithm;

[0032] When the photovoltaic welding ribbon vibrates, the edge contour becomes blurred or jittery. At this time, an immediate termination signal will be generated and uploaded to the controller. The corresponding controller will control the corresponding components to stop rotating and winding, realizing intelligent detection of the photovoltaic welding ribbon winding process;

[0033] A bracket 6 is fixedly connected to the top of the frame 1, and a rotating shaft 7 is arranged between the two brackets 6. Both ends of the rotating shaft 7 are movably connected to the corresponding bracket 6 through bearings. An electric push rod 4 is fixedly installed on the side wall of one of the frames 1. A push plate 5 is fixedly connected to the output end of the electric push rod 4. A rotating mechanism is installed on the outer side of the push plate 5. It should be noted that the rotating mechanism is an existing mechanism. When the winding drum for winding the photovoltaic welding tape is sleeved on the outer side of the rotating drum 12, the electric push rod 4 then uses the push plate 5 to push the rotating mechanism against the end of the rotating drum 12 and drive the rotating drum 12 to rotate and wind;

[0034] A rotating sleeve 8 is fixed on the outer side of the rotating shaft 7, and a rotating plate 9 is symmetrically fixedly connected to the outer side of the rotating sleeve 8. A receiving frame 11 for placing the winding reel is fixedly installed on the end of the rotating plate 9 away from the rotating sleeve 8 by bolts, and a rotating drum 12 is movably connected to one side of the receiving frame 11 through a bearing, and a tensioning adjustment component is arranged on the top of the support platform 2.

[0035] Two support plates 14 are fixedly connected to the top of the support platform 2, and a guide rod 15 and a threaded rod 16 are fixedly connected between the two support plates 14. Both ends of the guide rod 15 are fixedly connected to the inner side wall of the support plate 14, and both ends of the threaded rod 16 are movably connected to the inner side wall of the support plate 14 through bearings;

[0036] The tensioning adjustment assembly includes a slider 131 and a supporting frame 132 . A through groove and a threaded groove are formed through the side wall of the slider 131 . The slider 131 cooperates with the guide rod 15 and the threaded rod 16 through the through groove and the threaded groove respectively. The supporting frame 132 is fixedly installed on the top of the slider 131 .

[0037] A positioning rod 133 is fixed to the inside of the supporting frame 132 by spot welding, and a positioning groove 134 is opened on the inner wall of the supporting frame 132. A sliding seat 135 is slidably connected to the outer side of the positioning rod 133. One end of the sliding seat 135 is slidably connected in the positioning groove 134. One end of the sliding seat 135 is fixedly connected to a vertical plate 17. The top of the vertical plate 17 is fixedly connected to a frame 136. Two truncated cone guide rollers 137 are movably connected in the frame 136 through bearings, and the placement directions of the two truncated cone guide rollers 137 are opposite.

[0038] Both side walls of the vertical plate 17 are fixedly connected with protrusions 138, and the top of the support platform 2 is symmetrically fixedly connected with guide plates 139, and the two guide plates 139 are located between the sliders 131. The outer sides of the guide plates 139 are inclinedly provided with driving grooves 140, and the protrusions 138 are slidably connected in the corresponding driving grooves 140. By providing two guide plates 139, the moving stability of the tension adjustment assembly is increased;

[0039] During the specific setting, the feeding mechanism releases the photovoltaic welding tape and fixes one end of the photovoltaic welding tape on the surface of the winding drum, and then the winding drum winds the photovoltaic welding tape, and uses the light rod wire arrangement device 3 to evenly wind the photovoltaic welding tape on the surface of the winding drum;

[0040] like Figure 4 As shown, when the photovoltaic welding ribbon is located at the midpoint of the winding drum, the distance between the photovoltaic welding ribbon and the winding drum is the shortest. However, the length of the photovoltaic welding ribbon, the rotation speed of the winding drum and the moving speed of the wire arrangement mechanism remain unchanged, but the inclination direction of the photovoltaic welding ribbon is reversed, so that the longer photovoltaic welding ribbon enters a relaxed state, and the photovoltaic welding ribbon wound on the winding drum also becomes relaxed. In order to solve the problem of changes in the tension of the photovoltaic welding ribbon in the process of approaching the photovoltaic welding ribbon from the farthest end to the middle, the present invention is provided with two oppositely installed frustum guide rollers 137.

[0041] Combination Figure 4 , Figure 5 and Figure 7 , when the polished rod cable arranging device 3 moves to the left side of the device (from Figure 7 From a top-down perspective), during this process, the length of the photovoltaic welding ribbon is gradually stretched. When the photovoltaic welding ribbon is stretched to its longest length, the light rod cable arranger 3 moves in the opposite direction. During this process, the protrusion 138 slides in an obliquely upward direction in the driving groove 140. During the movement, the protrusion 138 drives the vertical plate 17 and the frame 136 to rise synchronously. In order to make the rise of the frame 136 more stable, a sliding seat 135 is fixedly connected to the side wall of the vertical plate 17. The sliding seat 135 slides stably along the positioning rod 133, and one end of the sliding seat 135 slides in the positioning groove 134. Under the action of the positioning groove 134 and the sliding seat 135, the frame 136 rises stably.

[0042] As the frame 136 drives the truncated cone guide roller 137 to rise, the contact diameter between the truncated cone guide roller 137 and the photovoltaic welding ribbon gradually increases, thereby achieving the purpose of regulating the slack of the photovoltaic welding ribbon, prompting the photovoltaic welding ribbon to always be in a taut state, avoiding the occurrence of problems such as photovoltaic welding ribbon jumpers.

[0043] Similarly, when the polished rod cable arrangement device 3 moves to the right side of the device (from Figure 7 From a top-down perspective), in the process of moving from the right side to the midpoint, the photovoltaic welding ribbon is always in a taut state under the action of the truncated cone guide roller 137.

[0044] Embodiment 2: A placement groove 18 is provided on the top of one of the frames 1, a gear 19 is fixed to one end of the rotating shaft 7 by spot welding, a bracket 2 is fixedly connected to the top of the frame 1, and a swing rail 20 and a rotating rod 21 are movably connected to the side wall of the bracket 2 through a bearing, and the bottom end of the swing rail 20 is located in the placement groove 18.

[0045] The side of the swing rail 20 away from the second bracket is fixedly connected with a fan-shaped plate 22 through a short rod, and the arc side of the fan-shaped plate 22 is fixedly installed with a rack 23 meshing with the gear 19. A swing groove 24 is opened on the outer side of the swing rail 20, and a rotating block 25 is fixedly connected to one side of the rotating rod 21. The rotating block 25 is slidably connected in the swing groove 24. A motor 2 for driving the threaded rod 16 to rotate is fixedly installed on one side of the support plate 14, and a motor 10 for driving the rotating rod 21 to rotate is fixedly installed on one side of the second bracket.

[0046] In the specific setting, after the winding drum has finished winding the photovoltaic welding tape, the photovoltaic welding tape is cut off and the motor 10 is started. The motor 10 drives the rotating rod 21 to rotate. The rotating rod 21 drives the swing rail 20 to deflect by the mutual cooperation of the rotating block 25 and the swing groove 24. The swing rail 20 drives the fan plate 22 to deflect synchronously through the short rod. The fan plate 22 drives the rotating shaft 7 to rotate by the mutual engagement of the rack 23 and the gear 19. The rotating shaft 7 drives the winding drum to flip 180 degrees through the rotating plate 9 connected to the outside, so that the unwound winding drum is moved to the side close to the light rod wire arranger 3, and the wound winding drum is moved to the side away from the light rod wire arranger 3, so as to facilitate the quick replacement of the winding drum.
