Description

Technical Field

[0001] The utility model relates to the technical field of precision cutting and laying machines, and particularly relates to a cutting device for a precision cutting and laying machine. Background Technique

[0002] The encapsulation of solar modules is the core technology of the entire module manufacturing industry. During the production process, a sticky thermosetting adhesive film (EVA, Ethylene Vinyl Acetate) is required to be placed in the middle of the laminated glass to ensure the tight adhesion between the glass surface and the battery chips, and to ensure that the core component, the battery chip, is cushioned by the double-layer EVA materials on the upper and lower sides. The tempered glass and the backplane material on the back greatly enhance the impact resistance and aging resistance of the module.

[0003] At present, in the field of solar cells, N-type monocrystalline heterojunction double-sided double-glass photovoltaic modules have the advantages of high efficiency, less light-induced degradation, low temperature coefficient, strong PID resistance, wear resistance, and better weather resistance than traditional modules. At the same time, the lead-free solder tape and the reduction of fluorine material pollution make the recycling cost low and the recycling more convenient, and the application range is wide. In the future, as a new generation of low-high-efficiency double-sided double-glass photovoltaic modules, double-sided double-glass heterojunction products will be applied in more and more scenarios. However, the amorphous silicon thin film deposited by chemical vapor deposition used in heterojunction batteries is not resistant to water vapor and is particularly sensitive to water. Water vapor will cause a more serious impact on the performance of heterojunctions. Compared with conventional homojunction crystalline silicon batteries, homojunction crystalline silicon can withstand the boiling water test, but the performance of heterojunctions will basically fail after the boiling water test. Therefore, compared with the traditional crystalline silicon encapsulation process, higher requirements are put forward for encapsulation during the production process of double-sided double-glass heterojunction photovoltaic modules.

[0004] At present, a Chinese invention with the publication number CN 118164310 A discloses a cutting and laying machine and a cutting and laying method for precise cutting and laying. It is equipped with a first flying cutting assembly fixedly connected to a traction device to trim the two ends of a tape along the conveying direction, and symmetrically fixed with a second flying cutting assembly on a transfer assembly to trim the two ends of the tape along the direction perpendicular to the conveying direction. The first flying cutting assembly is used to cut the tape along the length direction. After the tape cut along the length direction is conveyed to a glass panel through the transfer assembly, the second flying cutting assembly trims the two ends of the tape in the width direction, thereby ensuring the cutting accuracy of the tape. However, in the existing invention, the second flying cutting assembly drives a flying cutting pressure block to descend through a second lifting cylinder to press and fix the two ends of the tape lengthwise on a second flying cutting seat, and then a flying cutting slide drives a second flying cutting blade to slide to trim the two ends of the tape in the length direction. But when the flying cutting pressure block presses and fixes the tape on the second flying cutting seat, the tape may undergo a certain degree of elongation deformation due to the pressure, thereby affecting the cutting accuracy in the width direction of the tape, and thus reducing the accuracy of the heterojunction double-sided double-glass photovoltaic module, making improvement necessary. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a cutting device for a precise cutting and laying machine, which has the advantages of simple structure and improved cutting accuracy in the width direction of the tape.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: A cutting device for a precise cutting and laying machine includes a laying seat; an adjusting seat is slidably connected to the laying seat along the length direction parallel to the tape based on a sliding drive assembly, a lower cutting knife is fixedly connected to the adjusting seat along the direction perpendicular to the length direction of the tape, and an upper cutting knife that cooperates with the lower cutting knife to cut the tape is also slidably connected to the adjusting seat based on a lifting and sliding assembly. The upper cutting knife and the lower cutting knife are arranged in an alternating and symmetrical manner, and the cutting surfaces are in the same vertical plane.

[0007] The present utility model is further configured as: The upper cutting knife and the lower cutting knife have the same structure, both including a base and a cutting part fixedly connected to the base. The cutting part has a trapezoidal structure, and the part of the cutting part away from the cutting surface is inclined towards the base.

[0008] The present utility model is further configured as: The upper cutting knife and the lower cutting knife are made of high-hardness alloy material.

[0009] The present utility model is further configured as follows: The sliding drive assembly includes first drive rails symmetrically and fixedly connected to the laying base along the length direction parallel to the strip, at least one first slider fixedly connected to the adjustment base and slidably connected to the first drive rails, and a telescopic drive assembly fixedly connected to the laying base for driving the adjustment base to slide on the first drive rails.

[0010] The present utility model is further configured as follows: The telescopic drive assembly uses a telescopic electric cylinder, and the telescopic end of the telescopic electric cylinder is fixedly connected to the adjustment base.

[0011] The present utility model is further configured as follows: The lifting and sliding assembly includes second drive rails symmetrically and fixedly connected to the adjustment base along the vertical direction and a lifting base slidably connected to the second drive rails based on second sliders. The upper cutting knife is fixedly connected to the lifting base, and a lifting cylinder for driving the lifting base to lift is fixedly connected to the top of the adjustment base.

[0012] In summary, the present utility model has the following beneficial effects:

[0013] 1. An upper cutting knife and a lower cutting knife are arranged in a staggered and symmetric manner on the adjustment base, and the cutting surfaces of the upper cutting knife and the lower cutting knife are in the same vertical plane. When cutting the strip, the upper cutting knife is driven to descend by the sliding drive assembly. Since the cutting parts of the upper and lower cutting knives are trapezoid-shaped and the parts of the cutting parts away from the cutting surface are inclined towards the base, when the cutting edges of the upper and lower cutting knives respectively contact the upper and lower surfaces of the strip, the cutting parts at both ends of the strip cut will not press the strip, so that elongation deformation will not occur at both ends of the strip, ensuring the cutting accuracy in the width direction of the strip and improving the accuracy of the heterojunction double-sided double-glass photovoltaic module.

[0018] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0019] Embodiment:

[0020] Reference Figures 1 to 3 , a cutting device for a precision cutting and laying machine, including a laying seat 1, on which an adjusting seat 3 is slidably connected along the length direction parallel to the tape based on a sliding drive assembly 2. A lower cutting knife 4 is fixedly connected to the adjusting seat 3 along the length direction perpendicular to the tape. An upper cutting knife 6 that cooperates with the lower cutting knife 4 to cut the tape is also slidably connected to the adjusting seat 3 based on a lifting and sliding assembly 5. The upper cutting knife 6 and the lower cutting knife 4 are arranged in an alternating and symmetrical manner, and the cutting surfaces 43 are in the same vertical plane.

[0021] Reference Figure 1 and Figure 3 , specifically, the upper cutting knife 6 and the lower cutting knife 4 have the same structure, both including a base 41 and a cutting part 42 fixedly connected to the base 41. The cutting part 42 has a trapezoidal structure, and the part of the cutting part 42 away from the cutting surface 43 is inclined towards the base 41. The cutting surfaces 43 of the upper cutting knife 6 and the lower cutting knife 4 are arranged in the same vertical plane. When cutting the tape, the upper cutting knife 6 is driven to descend by the sliding drive assembly 2. Since the cutting parts 42 of the upper and lower cutting knives 4 have a trapezoidal structure and the part of the cutting part 42 away from the cutting surface 43 is inclined towards the base 41, when the cutting edges of the upper and lower cutting knives 4 respectively contact the upper and lower surfaces of the tape, the cutting parts 42 at both ends of the tape incision will not press the tape, thus preventing elongation deformation at both ends of the tape and ensuring the cutting accuracy in the width direction of the tape. In this embodiment, the upper cutting knife 6 and the lower cutting knife 4 are made of high-hardness alloy material to ensure the smoothness of the tape cutting process and the flatness of the incision.

[0022] Reference Figure 1 and Figure 2 , specifically, the sliding drive assembly 2 includes first drive slide rails 21 symmetrically and fixedly connected to the laying seat 1 along the length direction parallel to the tape. At least one first slider 22 slidably connected to the first drive slide rails 21 is fixedly connected to the adjusting seat 3. A telescopic drive assembly 23 for driving the adjusting seat 3 to slide on the first drive slide rails 21 is fixedly connected to the laying seat 1. When it is necessary to adjust the length of the tape, the telescopic drive assembly 23 drives the adjusting seat 3 to slide on the first drive slide rails 21 to adjust the cutting position. In this embodiment, the telescopic drive assembly 23 uses a telescopic electric cylinder to ensure the adjustment accuracy, and the telescopic end of the telescopic electric cylinder is fixedly connected to the adjusting seat 3.

[0023] Reference Figure 1 andFigure 2 Specifically, the lifting and sliding assembly 5 includes second driving slide rails 51 symmetrically and fixedly connected to the adjusting seat 3 along the vertical direction, and a lifting seat 52 slidably connected to the second driving slide rails 51 based on second sliders 54. The upper cutting knife 6 is fixedly connected to the lifting seat 52. A lifting cylinder 53 for driving the lifting seat 52 to lift is fixedly connected to the top of the adjusting seat 3. When cutting the strip, the lifting cylinder 53 drives the lifting seat 52 to slide on the second driving slide rails 51. By providing the second driving slide rails 51 and the second sliders 54, the stability of the lifting process of the upper cutting knife 6 is ensured, and the positioning accuracy between the upper cutting knife 6 and the lower cutting knife 4 is ensured.

[0024] Brief description of the usage process: When cutting the strip, the sliding drive assembly 2 drives the upper cutting knife 6 to descend. When the cutting edges of the upper and lower cutting knives 4 respectively contact the upper and lower surfaces of the strip, the cutting parts 42 at both ends of the strip incision will not crimp the strip, so that elongation deformation will not occur at both ends of the strip.

After reading this specification, those skilled in the art can make creative contributions to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
