[0045] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0046] Combine the following Figures 1 to 11 , describing an embodiment of the utility model.

[0047] According to an embodiment of the utility model, a photovoltaic module edge banding machine is provided, comprising: a frame 1, an edge banding module, a positioning assembly 3, a conveying mechanism 4, a suction cup assembly 5 and a lifting assembly 6. The edge banding module comprises an edge banding assembly 2, a transverse moving frame 7, a transverse driving mechanism and a longitudinal driving mechanism, the edge banding assembly 2 is movably arranged on the transverse moving frame 7 in the longitudinal direction, the longitudinal driving mechanism drives the edge banding assembly 2 to move in the longitudinal direction, the transverse driving mechanism is arranged on the frame 1 and drives the transverse moving frame 7 to move in the transverse direction, and the edge banding assembly 2 is suitable for banding the side of the photovoltaic module in the longitudinal direction; the positioning assembly 3 comprises a first positioning mechanism, the first positioning mechanism is arranged on the transverse moving frame 7, and the first positioning mechanism and the transverse moving frame 7 share the transverse driving mechanism; the conveying mechanism 4 is arranged on the inner side of the edge banding module and is suitable for conveying the photovoltaic module; the suction cup assembly 5 is arranged on the inner side of the edge banding module and is suitable for sucking the photovoltaic module.

[0048] The photovoltaic module edge banding machine of this embodiment is used. When edge banding, the photovoltaic module is transported to the conveying mechanism 4. After the conveying mechanism 4 transports the photovoltaic module to the designated position, the transverse driving mechanism drives the first positioning mechanism to move horizontally. The first positioning mechanism positions the photovoltaic module, and then sucks the photovoltaic module through the suction cup assembly 5. The longitudinal driving mechanism drives the transverse moving frame 7 to move, thereby driving the edge banding assembly 2 to bandage the side of the photovoltaic module. After the edge banding is completed, the conveying mechanism 4 sends the photovoltaic module to the next station. The edge banding machine realizes automatic edge banding, has a simple structure, high edge banding efficiency, high tape laminating quality, beautiful appearance, no bubbles or wrinkles, an edge banding yield of more than 99%, and is compatible with all specifications of module products currently on the market. By sharing the transverse driving mechanism with the first positioning mechanism, the number of driving mechanisms can be reduced, saving costs.

[0049] In one embodiment, Figure 1 and Figure 2As shown, the edge banding assembly 2 includes an edge banding seat 201, an unwinding mechanism 202, a material guiding mechanism 203, a cutting mechanism 204, a tape pressing mechanism 205, a profiling mechanism 206 and a pressing mechanism 207. The unwinding mechanism 202 is arranged on the edge banding seat 201, the material guiding mechanism 203 is located on the inner side of the unwinding mechanism 202, the material guiding mechanism 203, the tape pressing mechanism 205, the cutting mechanism 204, the profiling mechanism 206 and the pressing mechanism 207 are arranged on the edge banding seat 201 in sequence along the longitudinal direction, the unwinding mechanism 202 is suitable for placing and unwinding the tape roll 208, the material guiding mechanism 203 is suitable for guiding the released tape, the tape pressing mechanism 205 is suitable for pressing or loosening the tape, the profiling mechanism 206 is suitable for pressing the tape on the photovoltaic module, and the pressing mechanism 207 is suitable for pressing the tape on the photovoltaic module. After the tape roll 208 is fixed on the unwinding mechanism 202, the tape head is placed at the tape pressing mechanism 205 through the material guiding mechanism 203, and the tape head is pressed by the tape pressing mechanism. During the edge sealing operation, the edge sealing component 2 is moved to the initial position of the edge sealing through the longitudinal driving mechanism. When the edge of the photovoltaic module contacts the tape, the tape pressing mechanism 205 releases the tape, and the edge sealing component 2 moves forward along the side of the photovoltaic module. The tape is attached to the photovoltaic module and passes through the profiling mechanism 206 and the pressing mechanism 207 in turn, thereby completing the edge sealing operation. After the edge sealing is completed, the tape is first pressed by the tape pressing mechanism 205, and then the tape is cut by the cutting mechanism 204. The structure of the edge sealing component 2 is simple and easy to implement. The edge sealing module has high edge sealing efficiency, good quality, reliable function, flexible compatibility with component products of different specifications, and can be switched with one key to realize "on-demand" production. It has a high degree of automation. Except for replacing the tape, all other actions are automatically completed by the equipment.

[0050] In the related art, the tape roll uses a damping tensioning mechanism to achieve the tensioning of the tape roll. The damping tensioning mechanism uses a torque motor or a spring mechanism to compress and generate friction. The torque motor itself is relatively expensive and requires electric drive when working, which increases the cost of electrical control. The spring mechanism is easy to wear, and the wear will cause the damping to decrease, and the damping needs to be adjusted frequently.

[0051] In one embodiment, Figure 2 and Figures 6 to 8 As shown, the unwinding mechanism 202 includes a fixed shaft 2021, an unwinding drum 2022 and a damping member. The unwinding drum 2022 is rotatably arranged on the fixed shaft 2021. The unwinding drum 2022 is suitable for placing the tape roll 208. The damping member is arranged on the unwinding drum 2022 and abuts against the fixed shaft 2021. The position of the damping member on the unwinding drum 2022 is adjustable to adjust the damping size when the tape roll 208 on the unwinding drum 2022 rotates. The damping size is adjusted by adjusting the position of the damping member, thereby achieving the tension of the tape. The damping member has a simple structure, and the processing and maintenance costs are extremely low. It does not need to adjust the damping size frequently, and is convenient to use.

[0052] Specifically, the damping member is a positioning bead 2023 threadedly connected to the unwinding drum 2022. A plurality of positioning beads 2023 with elastic members inside are installed around the fixed shaft 2021, and the ball head of the positioning bead 2023 is pressed on the fixed shaft 2021. Since the positioning bead 2023 is equipped with an elastic member inside, the pressure of the elastic member will act on the contact surface between the ball head and the fixed shaft 2021, and the tape roll 208 will generate damping when rotating around the fixed shaft 2021. The pressure of the elastic member is adjusted by adjusting the position of the positioning bead 2023, thereby adjusting the damping size. Since there is rolling friction between the ball head of the positioning bead 2023 and the fixed shaft 2021, there is almost no wear, so the damping size can be stable for a long time and does not need to be adjusted.

[0053] Furthermore, a threaded hole is provided on the unwinding drum 2022, and the outer shell of the positioning column is threadedly connected to the threaded hole. An elastic member such as a spring is provided in the outer shell. The ball head is installed at the opening of the outer shell and abuts against the spring. The positioning bead 2023 and the elastic clamping sheet 2024 are installed on the unwinding drum 2022. After the tape roll 208 is placed, the elastic clamping sheet 2024 is squeezed and deformed, and the tape roll 208 is clamped by the elastic force generated by the deformation. After the tape roll 208 is placed, the tape head of the tape roll 208 is pulled out by manual traction, and the tape roll 208 rotates accordingly. The positioning bead 2023 generates damping when driven by the tape roll 208 to rotate, so that the pulled tape is always in a tensioned state. The size of the ball head pressing force is controlled by adjusting the position of the positioning bead 2023, thereby realizing the control of the damping size when the tape roll 208 rotates.

[0054] In one embodiment, the unwinding mechanism 202 further includes an elastic clamping piece 2024 fixed on the unwinding drum 2022, and the elastic clamping piece 2024 includes a guide segment and a clamping segment arranged at an angle, and the clamping segment is suitable for applying an elastic force to the tape roll 208 to fix the tape roll 208 on the unwinding drum 2022. The elastic clamping piece 2024 fixes the tape roll 208 on the unwinding drum 2022 to prevent the tape roll 208 from rotating around the unwinding drum 2022. The elastic clamping piece 2024 has a simple structure and is easy to manufacture. The setting of the guide segment makes it convenient to put the tape roll 208 on the unwinding drum 2022.

[0055] Specifically, the upper end of the clamping segment is inclined outwardly relative to the axis of the unwinding drum 2022, and the upper end of the guide segment is inclined inwardly relative to the clamping segment. The bottom of the unwinding drum 2022 has a supporting edge extending outwardly, and the tape roll 208 is supported by the supporting edge.

[0056] Furthermore, the unwinding mechanism 202 also includes a mounting plate 2025, a pressure plate 2026, a bearing 2027, and a bushing 2028. The mounting plate 2025 is fixed on the edge banding seat 201, the fixed shaft 2021 is fixed on the mounting plate 2025, the bushing 2028 and the bearing 2027 are sleeved on the fixed shaft 2021, the bushing 2028 is located below the bearing 2027, the unwinding drum 2022 is mounted on the fixed shaft 2021 through the bearing 2027 and can rotate relative to the fixed shaft 2021, and the pressure plate 2026 is mounted on the upper end of the fixed shaft 2021 and limits the upper end of the unwinding drum 2022.

[0057] It should be noted that the positioning bead 2023 may also be referred to as a ball plunger or a spring plunger. By changing the size of the unwinding drum 2022 or the shape of the elastic clamping piece 2024, it can be applied to rolls of different diameters.

[0058] In one embodiment, Figure 2 and Figure 3 As shown, the material guiding mechanism 203 includes a one-way guide wheel 2031, and the one-way guide wheel 2031 is unidirectionally rotatably arranged on the edge banding seat 201. The one-way guide wheel 2031 ensures that the adhesive tape can only move in one direction, thereby preventing the adhesive tape from moving in the opposite direction.

[0059] Further, the one-way guide wheel 2031 is installed on the edge sealing seat 201 through a one-way bearing 2027. The one-way bearing 2027 is specifically a one-way needle roller bearing.

[0060] Specifically, the material guiding mechanism 203 further includes a freely rotatable guide wheel 2032 , which is located between the one-way guide wheel and the tape pressing mechanism 207 , and the tape is guided by the guide wheel 2032 .

[0061] Furthermore, the material guiding mechanism 203 further comprises a guide wheel seat, which is arranged on the edge banding seat 201 , and the guide wheel 2032 and the one-way guide wheel 2031 are both mounted on the guide wheel seat.

[0062] In one embodiment, Figure 2 and Figure 3As shown, the adhesive tape pressing mechanism 205 includes an upper pressing sheet 2051, a lower pressing sheet 2052, a guide pressing wheel 2053 and a pressing drive 2054. The upper pressing sheet 2051 and the lower pressing sheet 2052 are arranged at intervals from top to bottom, the guide pressing wheel 2053 is rotatably arranged on the edge banding seat 201, the upper pressing sheet 2051 and the lower pressing sheet 2052 are arranged opposite to the guide pressing wheel 2053, and the pressing drive 2054 is connected to the upper pressing sheet 2051 and the lower pressing sheet 2052 to drive the upper pressing sheet 2051 and the lower pressing sheet 2052 to press the adhesive tape onto the guide pressing wheel 2053. The space between the upper pressing sheet 2051 and the lower pressing sheet 2052 forms an escape space for avoiding photovoltaic components, and the adhesive tape head can be fixed by pressing the adhesive tape onto the guide pressing wheel 2053 through the upper pressing sheet 2051 and the lower pressing sheet 2052.

[0063] Furthermore, the number of the guide pressing wheels 2053 is two, and the pressing driving member 2054 is a driving cylinder, etc., and the driving cylinder is an air cylinder or an oil cylinder, etc.

[0064] Specifically, an upper stopper wheel 2055 is provided on one side of the upper pressing sheet 2051 close to the profiling mechanism 206, and a lower stopper wheel 2056 is provided on one side of the lower pressing sheet 2052 close to the profiling mechanism 206. When the cutting mechanism 204 cuts the adhesive tape, the adhesive tape is cut between the upper stopper wheel 2055 and the upper pressing sheet 2051 and the lower stopper wheel 2056 and the lower pressing sheet 2052, and the adhesive tape is pressed on one side of the cut-off point of the adhesive tape, and the adhesive tape is blocked by the stopper wheel on the other side, so as to facilitate the cutting of the adhesive tape. It is understandable that the upper stopper wheel 2055 and the lower stopper wheel 2056 may not be provided.

[0065] In one embodiment, Figure 2 and Figure 4 As shown, the profiling mechanism 206 includes a profiling seat 2061 and a plurality of profiling wheels 2062, the profiling seat 2061 is fixed on the edge banding seat 201, the plurality of profiling wheels 2062 are mounted on the profiling seat 2061 and arranged in the longitudinal direction, each profiling wheel 2062 has two symmetrically arranged frustum surfaces, and the cone angles of the frustum surfaces of the plurality of profiling wheels 2062 gradually decrease in the direction from the cutting mechanism 204 to the pressing mechanism 207. The angle between the busbars of the two frustum surfaces of each profiling wheel 2062 closest to the side of the photovoltaic module forms a pressure angle for pressing the adhesive tape onto the photovoltaic module, and in the direction from the cutting mechanism 204 to the pressing mechanism 207, the pressure angles of the plurality of profiling wheels 2062 gradually increase, so that the adhesive tape is gradually pressed onto the upper and lower surfaces of the photovoltaic module, and then the adhesive tape is adhered to the upper and lower surfaces of the photovoltaic module.

[0066] Further, the space between the two round table surfaces of each profiling wheel 2062 also forms a space for avoiding the photovoltaic module. The number of the profiling wheels 2062 is four. It can be understood that the number of the profiling wheels 2062 is not limited to this, and the number of the profiling wheels 2062 can be set according to specific circumstances.

[0067] It should be noted that the cone angle of the frustum refers to the angle between two generatrixes of the cross section passing through the axis of the frustum.

[0068] In one embodiment, Figure 2 and Figure 5 As shown, the clamping mechanism 207 includes a clamping fixing plate 2071, an upper fixing seat 2078, a lower fixing seat 2079, an upper pressing wheel bracket 2072, an upper pressing wheel 2073, a lower pressing wheel bracket 2074, a lower pressing wheel 2075, an upper elastic member, a lower elastic member, an upper connecting member 2076 and a lower connecting member 2077.

The lower pressure wheel bracket 2074 is connected to the lower connecting member 2077, and the lower connecting member 2077 cooperates with the lower fixed seat 2079. A lower elastic member is provided between the lower pressure wheel bracket 2074 and the lower fixed seat 2079. The elastic force of the upper elastic member applies a downward force to the upper pressure wheel 2073, and the elastic force of the lower elastic member applies an upward force to the lower pressure wheel 2075, and then the tape is pressed onto the photovoltaic module through the upper pressure wheel 2073 and the lower pressure wheel 2075, so that the tape is firmly bonded to the photovoltaic module, ensuring that the tape and the photovoltaic module are reliably bonded.

[0069] Specifically, the upper elastic member and the lower elastic member are springs, etc. The upper connecting member 2076 and the lower connecting member 2077 are bolts or screws, etc., and the bolts or screws are sleeved with springs.

The first lifting drive member is specifically a cylinder or an oil cylinder.

The two second positioning mechanisms are respectively a front positioning mechanism 301 and a rear positioning mechanism 302. After the photovoltaic assembly is transported to the designated position by the conveying mechanism 4, the front and rear positioning mechanisms both use two groups of cylinders to correct the front and rear of the photovoltaic assembly, and then the left and right positioning mechanisms on both sides are driven by the servo motor to move closer to the middle, pushing the photovoltaic assembly to achieve left and right correction positioning.

The several conveyors are connected by the transmission shaft. The speed regulating motor drives the transmission shaft to rotate, thereby driving the several conveyors to move simultaneously, so as to realize the entry and exit of the photovoltaic module in the edge sealing station. The conveyor adopts a belt conveyor or the like.

[0087] It should be noted that the left, right, front and back directions are Figure 1 The arrows in the middle point to the directions of “left, right, front, and back”.

[0088] The working process of the photovoltaic module edge banding machine is described below:

[0089] Photovoltaic components such as double-glass components enter the edge sealing station through the conveying mechanism 4, and then the front positioning mechanism 301, the rear positioning mechanism 302, the left positioning mechanism 303, and the right positioning mechanism 304 correct and position the product. After the photovoltaic component is positioned, the lifting mechanism drives the conveying mechanism 4 to descend, and the photovoltaic component falls on the suction cup assembly 5, and the suction cup assembly 5 sucks the photovoltaic component. Then, the two edge sealing modules perform edge sealing operations on the left and right edges of the photovoltaic component. After the edge sealing is completed, the lifting mechanism drives the conveying mechanism 4 to rise, lifts the photovoltaic component and sends it to the next process.
