Description

Technical Field

[0001] This utility model belongs to the field of solar cell manufacturing, and in particular relates to a material roll feeding mechanism and an adhesive tape applicator. Background Technology

[0002] In the production process of photovoltaic modules, several individual solar cells need to be welded into a string, and then several strings are welded side by side into a solar panel, which is a solar photovoltaic module.

[0003] A solar panel is composed of multiple strings of batteries welded together. Before welding, the battery strings need to be arranged and the spacing between adjacent strings needs to be adjusted. Welding can only proceed after the battery strings are arranged neatly. To prevent the battery strings from moving and changing the spacing during handling, welding, or subsequent lamination processes, high-temperature tape is used to fix adjacent battery strings before welding. Therefore, an adhesive application mechanism is required.

[0004] Generally, the tape unwound from the tape roll is wound around the guide roller. The tape is fed through the guide roller to the tape cutting position. When the tape passes through the guide roller, it will deviate laterally, resulting in irregular tape after subsequent cutting, which affects the bonding quality between the two battery strings. Utility Model Content

[0005] The main purpose of this utility model is to provide a material roll feeding mechanism to ensure stable material conveying.

[0006] The present invention achieves the above objectives through the following technical solution: a material roll feeding mechanism, comprising a mounting plate, a material carrier roller, a first roller, a second roller, and a correction roller, wherein the material carrier roller is rotatably mounted on the mounting plate and the material carrier roller feeds the material roll.

[0007] The first roller is rotatably mounted on the mounting plate, and the first roller is spaced apart from the material carrier roller, with the shafts of the first roller and the material carrier roller being parallel; the second roller is rotatably mounted on the mounting plate, with the shaft of the second roller arranged at an angle to the shaft of the first roller.

[0008] The correction roller is rotatably mounted on the mounting plate. The shaft of the correction roller is parallel to the shaft of the second roller. The middle part of the correction roller has an annular groove, and the width of the annular groove matches the width of the material.

[0009] Furthermore, the angle θ between the shaft core of the second roller and the shaft core of the first roller is 30° to 150°.

[0010] Furthermore, the angle θ between the shaft of the second roller and the shaft of the first roller is 60° to 120°. This allows the conveyor belt to twist appropriately from the first roller to the second roller, further improving the stability of the conveyor belt transport.

[0011] Furthermore, the annular groove has a tangent perpendicular to the axial direction of the straightening roller, and the tangent of the annular groove is located on the same plane as the axis of the first roller.

[0012] Furthermore, the height of the second roller shaft core is consistent with the height of the shaft core of the annular groove of the correction roller, and the outer diameter of the second roller is the same as the outer diameter of the correction roller.

[0013] Furthermore, the correction roller and the second roller are located below the first roller, and the material loading roller is located between the first roller and the second roller.

[0014] Furthermore, the correction roller includes a roller body, a first ring, and a second ring, the first ring and the second ring being sleeved on the roller body, and the first ring, the second ring and the circumferential surface of the roller body forming an annular groove.

[0015] Furthermore, the mounting plate includes a first plate body and a second plate body, the surfaces of the first plate body and the second plate body are arranged at an angle, the surface of the first plate body is perpendicular to the shaft of the first roller, and the surface of the second plate body is perpendicular to the shaft of the second roller.

[0016] Furthermore, an angular reinforcing plate is provided between the first plate and the second plate, and the two reinforcing plates are arranged at intervals.

[0017] This utility model also provides a tape applicator, including the aforementioned material roll feeding mechanism. The tape applicator further includes a tape adsorption component and a tape cutting component. The tape adsorption component is arranged adjacent to the correction roller. The tape adsorption component can adsorb the tape and transport it to the cutting station. The cutting component can cut the tape on the tape adsorption component into small sections of tape.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention uses an angled arrangement between the first and second rollers. The tape is then twisted and wound downwards around the second roller by the first roller, making it difficult for the tape to deviate during transport. Finally, the tape is sent to the subsequent cutting position by the correction roller. The inner wall of the annular groove of the correction roller can limit the deviation of the tape, ensuring that it can be accurately delivered to the tape adsorption assembly, thereby improving the tape cutting quality.

[0027] This utility model provides a material roll feeding mechanism, such as... Figures 1-7 As shown.

[0028] A material roll feeding mechanism includes a mounting plate 10, a material carrier roller 20, a first roller 30, a second roller 40, and a correction roller 50. The material carrier roller 20 is rotatably mounted on the mounting plate 10, and the material carrier roller 20 feeds the material roll 1.

[0029] The first roller 30 is rotatably mounted on the mounting plate 10. The first roller 30 and the material carrier roller 20 are spaced apart, and the shafts of the first roller 30 and the material carrier roller 20 are parallel.

[0030] The second roller 40 is rotatably mounted on the mounting plate 10, and the shaft of the second roller 40 is arranged at an angle to the shaft of the first roller 30.

[0031] The correction roller 50 is rotatably mounted on the mounting plate 10. The shaft of the correction roller 50 is parallel to the shaft of the second roller 40. The middle part of the correction roller 50 is an annular groove 51, and the width of the annular groove 51 matches the width of the material.

[0032] The material roll 1 of this utility model can be a strip of material such as adhesive tape or reflective film. This utility model does not limit the type of material supplied to the material roll 1. The following description only uses adhesive tape supplied to the material roll 1 as an example.

[0033] Material roll 1 is fed to the material carrier roller 20, and material roll 1 is unloaded. The tape is wound from bottom to top onto the first roller 30. In this invention, after the first roller 30 and the second roller 40 are arranged at an angle, the tape is twisted downward from the first roller 30 and wound onto the second roller 40. The tape is difficult to deviate during the conveying process. Finally, the tape is sent to the subsequent cutting position by the correction roller 50. The inner wall of the annular groove 51 of the correction roller 50 can limit the deviation of the tape and ensure that it can be accurately sent to the tape adsorption assembly 60, thereby improving the tape cutting quality.

[0034] Specifically, the angle θ between the shaft of the second roller 40 and the shaft of the first roller 30 is 30° to 150°.

[0035] The angle θ can be 40°, 45°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, or 140°.

[0036] When θ < 60°, the tape twists insufficiently and the offset rate is large; when θ > 120°, the tape is overstretched. Therefore, the preferred arrangement is that the angle θ between the shaft of the second roller 40 and the shaft of the first roller 30 is 60° to 120°. See [link to relevant documentation] Figure 3 When θ = 90°, the offset rate is small, so the conveyor belt can be moderately twisted from the first roller 30 to the second roller 40, further improving the stability of the conveyor belt.

[0037] The annular groove 51 has a cross-section 511 perpendicular to the axial direction of the straightening roller 50, and the cross-section 511 of the annular groove 51 is located on the same plane as the axis O' of the first roller 30. This can improve the stability of the conveyor belt being transported from the first roller 30 and the second roller 40 to the straightening roller 50.

[0038] The core height of the second roller 40 is the same as the core height of the annular groove 51 of the straightening roller 50, and the outer diameter of the second roller 40 is the same as the outer diameter of the straightening roller 50. The conveyor belt can smoothly transition from the second roller 40 to the straightening roller 50.

[0039] In the specific arrangement of the rollers of the material roll feeding mechanism of this utility model, the correction roller 50 and the second roller 40 are located below the first roller 30, and the material carrying roller 20 is located between the first roller 30 and the second roller 40.

[0040] The correction roller 50 includes a roller body 52, a first ring 53 and a second ring 54. The first ring 53 and the second ring 54 are sleeved on the roller body 52, and the first ring 53, the second ring 54 and the circumferential surface of the roller body 52 form an annular groove 51.

[0041] The width of the annular groove 51 can be adjusted by replacing the first ring 53 or the second ring 54 with different axial thicknesses, thereby improving the adaptability to tapes of different widths. Alternatively, the first ring 53 or the second ring 54 can be screwed onto the roller body 52, and the width of the annular groove 51 can be adjusted by adjusting the screwing distance of the first ring 53 or the second ring 54, thereby improving the convenience of adjusting the width of the annular groove 51.

[0042] The mounting plate 10 includes a first plate 11 and a second plate 12. The surfaces of the first plate 11 and the second plate 12 are arranged at an angle. The surface of the first plate 11 is perpendicular to the shaft of the first roller 30, and the surface of the second plate 12 is perpendicular to the shaft of the second roller 40.

[0043] An angled reinforcing plate 13 is provided between the first plate 11 and the second plate 12, and the two reinforcing plates 13 are arranged at intervals.

[0044] This utility model also provides a tape applicator, including the aforementioned material roll feeding mechanism. The tape applicator further includes a tape adsorption component 60 and a tape cutting component 70. The tape adsorption component 60 is arranged adjacent to the correction roller 50. The tape adsorption component 60 can adsorb the tape and transport it to the cutting station. The cutting component can cut the tape on the tape adsorption component 60 into small sections of tape.

[0045] The specific tape adsorption component 60 and tape cutting component 70 are existing technologies. You can refer to the published patent CN221420191U - A high-efficiency adhesive tape pasting device for fixing photovoltaic module battery strings, or the published patent CN212449980U - A high-rhythm adhesive pasting structure.

[0046] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
