Description

Technical Field

[0001] The present application relates to the technical field of solar cells, and in particular to a film cutting machine. Background Art

[0002] In the production process of photovoltaic modules, the adhesive film and the glass need to be laid together. Currently, a cutting machine is used on site to lay the adhesive film, and then a heating point is applied when the film passes through the assembly line to promote the adhesion between the adhesive film and the glass.

[0003] Because the current production process of photovoltaic modules is different from before, all polypropylene elastomer film (POE film) is used. Compared with the polyethylene-polyvinyl acetate copolymer film (EVA film) used before, POE film will slip when it is pushed forward on the assembly line, resulting in the problem of film deviation during the hot-pressing process on the assembly line.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0045] The embodiment of the present application provides a film cutting machine and a welding method thereof, by adding a set of hot spot mechanism and glass lifting mechanism inside the cutting machine platform, the cutting machine platform and the glass lifting mechanism share a PLC (Programmable Logic Controller), the hot spot mechanism is equipped with an independent PLC (Programmable Logic Controller) for program control, and then the above-mentioned PLCs are integrated in the same controller, coordinated and controlled by the controller, and linked by staggered program points, without the need to add additional equipment or occupy the entire assembly line rhythm, can reduce personnel repetitive mechanical movements, reduce personnel labor intensity, thereby reducing unnecessary manpower and time waste, and improving the comprehensive operation efficiency of equipment.

[0046] The following is a detailed description of a film cutting machine provided in this embodiment in conjunction with the accompanying drawings. Figure 1 , Figure 2 As shown, it includes: a cutting machine 1, a glass lifting mechanism 2, a hot spot mechanism 3 and a controller 4, wherein the glass lifting mechanism 2 and the hot spot mechanism 3 are both arranged on the cutting machine 1, wherein: the cutting machine 1 is used to receive a glass sheet 5, and cut and lay the adhesive film at a predetermined position; the glass lifting mechanism 2 can be raised to support the glass sheet 5 located at a predetermined position; the hot spot mechanism 3 can be lowered to perform a hot spot operation on the adhesive film on the glass sheet 5 at a position where the glass lifting mechanism 2 lifts and supports it; the controller 4 is connected to the cutting machine 1, the glass lifting mechanism 2, and the hot spot mechanism 3 by signal, and is used to control the operation of the cutting machine 1, the glass lifting mechanism 2, and the hot spot mechanism 3.

[0047] In this embodiment, a set of glass lifting mechanism 2 and hot-point mechanism 3 are added inside the cutting machine 1. The glass lifting mechanism 2 can lift and support the glass sheet 5 at a predetermined position, so as to prevent the glass sheet 5 from being deformed and cracked when hot-pointing. The hot-point mechanism 3 can realize automatic hot-pointing of the glass sheet 5 and the adhesive film at the position where the glass lifting mechanism 2 lifts and supports the glass sheet 5. On the one hand, the hot-point mechanism 3 and the glass lifting mechanism 2 are added inside the cutting machine 1, and the cutting machine 1 and the glass lifting mechanism 2 share a PLC for program control, and the hot-point mechanism 3 is equipped with an independent PLC for program control, and then the above PLCs are integrated in the same The controller 4 is used for coordinated control, and the program points are staggered for linkage, without adding additional equipment or occupying the entire assembly line rhythm; on the other hand, the film does not need to be moved after being cut by the cutting machine 1. When the glass sheet 5 is laid with the film and has not moved forward, it can be hot-stamped by the hot-stamping mechanism 3 inside the cutting machine 1, which can achieve a perfect hot-stamping effect. In this way, the film will not be offset, which improves the accuracy. At the same time, it can also solve the problem of manual hot-stamping wasting manpower and repetitive mechanical work of personnel, so as to improve the efficiency of the production process and gradually realize the automation of the workshop. It is an indispensable tooling requirement.

[0048] In this embodiment, it should be noted that the cutting machine 1 integrates multiple mechanisms such as a cutting mechanism, a laying mechanism, a straightening mechanism, a film clamping mechanism, and a conveying mechanism. Through the mutual cooperation of multiple mechanisms, multiple functions such as film cutting and laying can be achieved. The cutting machine 1 can be a cutting machine 1 on an existing solar panel production equipment, and no further details will be given here.

[0049] The present application focuses on introducing the hot spot mechanism 3 and the glass lifting mechanism 2 added to the cutting machine 1. The cutting machine 1 has a working space 11 for the glass sheet 5 to flow in or out. The hot spot mechanism 3 and the glass lifting mechanism 2 are arranged relatively to each other in the cutting machine 1. It can be understood that the glass lifting mechanism 2 is arranged at the lower position of the internal working space 11 of the cutting machine 1, and the hot spot mechanism 3 is arranged at the upper position of the internal working space 11 of the cutting machine 1. As a result, when the glass sheet 5 flows into the working space 11 of the cutting machine 1 through the production line and advances to the predetermined position, it stops. At this time, the glass lifting mechanism 2 can rise to contact the bottom surface of the glass sheet 5 to support the glass sheet 5 to prevent the hot spot mechanism 3 from causing deformation of the glass sheet 5 when pressing down. Then the hot spot mechanism 3 descends to perform the film hot spot operation on the glass sheet 5 located at the predetermined position at the position supported by the glass lifting mechanism 2. It should be noted that the glass lifting mechanism 2 is provided in two groups, and the two groups of glass lifting mechanisms 2 are arranged at intervals inside the cutting machine 1 along the short side direction W thereof, that is, the conveying direction of the glass sheet 5. When the glass sheet 5 flows into the working space 11 of the cutting machine 1 and reaches the predetermined position, the two groups of glass lifting mechanisms 2 correspond exactly to the lower part of the two long sides of the glass sheet 5 and close to the middle position, so that the glass lifting mechanisms 2 rise and contact the middle bottom surface position of the long side of the glass sheet 5 for support. It is understandable that when the glass sheet 5 is transported to the cutting machine table 1 by means of a conveyor belt or the like, it is suspended in the position where there is no support from the conveyor belt. At this time, directly using the hot spot mechanism 3 to press down the suspended position of the glass sheet 5 can easily cause the glass sheet 5 to deform or burst. Therefore, in this embodiment, a glass lifting mechanism 2 is added, and the glass lifting mechanism 2 rises and contacts the bottom surface of the glass sheet 5. Therefore, when the hot spot mechanism 3 presses down to hot the glass sheet 5, it can provide a stable supporting force for the glass sheet 5 at the hot spot position, thereby preventing the glass sheet 5 from deforming or bursting.

[0050] Please refer to Figure 1 , Figure 2 as well as Figure 3As shown, in this embodiment, it should be noted that the glass lifting mechanism 2 includes a fixing part 21, a lifting part 22 and a holding part 23. The fixing part 21 is used to be fixed on the cutting machine table 1. For example, the fixing part 21 can be a fixed profile, which is in the shape of a long strip. The two ends of the fixed profile are detachably mounted at the lower position inside the cutting machine table 1 by means of bolts or the like. The lifting part 22 is mounted on the cutting machine table 1 through the fixing part 21. The lifting part 22 can be set as a three-axis cylinder. The cylinder body of the three-axis cylinder is mounted on the fixing part 21, and the output shaft of the three-axis cylinder is vertically arranged upward. The holding part 23 is mounted on the output end of the lifting part 22, that is, the output end of the three-axis cylinder is connected to the lifting part 23. Under the control of the lifting part 22, the lifting part 23 rises to contact the bottom surface of the glass sheet 5 at the predetermined position. The lifting part 23 is set as a plate. The plate-like structure better fits the lower surface of the glass sheet 5, thereby facilitating a close fit.

[0051] Please refer to Figure 1 , Figure 4 As shown, in the present embodiment, it should be noted that the hot spot mechanism 3 includes a mounting portion 31, a descending portion 32 and a hot spot fixture 33; the mounting portion 31 is mounted at an upper position of the cutting machine table 1, the descending portion 32 is mounted on the cutting machine table 1 through the mounting portion 31, and the hot spot fixture 33 is mounted at the output end of the descending portion 32; thus, the hot spot fixture 33 descends under the control of the descending portion 32 and implements a hot spot operation on the adhesive film on the glass sheet 5 located at a predetermined position at a position supported by the glass lifting mechanism 2.

[0052] In some embodiments, the mounting portion 31 includes an X-axis linear guide rail 311 and a Y-axis linear guide rail 312. The X-axis linear guide rail 311 is extended along the long side direction L of the cutting machine table 1, and the Y-axis linear guide rail 312 is extended along the short side direction W of the cutting machine table 1. In this embodiment, the long side direction L of the cutting machine table 1 corresponds to the long side direction of the glass sheet 5, and the short side direction W of the cutting machine table 1 corresponds to the short side direction of the glass sheet 5. Two X-axis linear guides 311 are arranged at intervals along the short side direction W of the cutting machine table 1, and the Y-axis linear guide 312 spans the two X-axis linear guides 311, and the two ends of the Y-axis linear guide 312 slide on the X-axis linear guide 311 respectively. The Y-axis linear guide 312 can be set as a gantry structure, so that a larger space can be reserved below the Y-axis linear guide 312 through the gantry structure. The space can avoid the cutting machine table 1 or provide for the installation of the descending part 32 and the hot spot fixture 33.

[0053] In one example, the Y-axis linear guide 312 is slidably connected to the X-axis linear guide 311 through the first moving part 34. Specifically, the Y-axis linear guide 312 includes two vertical parts 3121 and one horizontal part 3122. The two vertical parts 3121 and the two X-axis linear guides 311 are arranged one by one. The lower end of the vertical part 3121 is slidably connected to the X-axis linear guide 311, and the horizontal part 3122 is connected to the upper end of the two vertical parts 3121. Thus, the two vertical parts 3121 and the horizontal part 3122 constitute a gantry structure. When the vertical part 3121 of the Y-axis linear guide 312 moves along the X-axis linear guide 311, the position of the hot spot jig 33 along the long side direction L of the cutting machine table 1 can be adjusted to adapt to the length of the glass sheet 5 or the change of the stop position of the glass sheet 5, so that it is more flexible in use.

[0054] Preferably, a first moving part 34 is slidably provided on the X-direction linear guide 311, and the lower end of the vertical part 3121 in the Y-direction linear guide 312 is connected to the first moving part 34, so that the Y-direction linear guide 312 can slide on the X-direction linear guide 311 through the first moving part 34 to complete the motion track along the X direction. Here, by adopting the cooperation of the first moving part 34 and the X-direction linear guide 311, the Y-direction linear guide 312 is more stable when moving.

[0055] Please refer to Figure 4 , Figure 5 As shown, in order to ensure the stability of the hot stamping jig 33 after adjusting a certain position, a tightening member 6 is further provided on the first movable part 34, and the tightening member 6 is used to tighten or loosen the position of the first movable part 34 on the X-direction linear guide 311. The position of the first movable part 34 on the X-direction linear guide 311 can be adjusted by the tightening member 6. Since the lower end of the Y-direction linear guide 312 is connected to the first movable part 34, the position of the Y-direction linear guide 312 can be adjusted in the same way, thereby ensuring the stability of the hot stamping position. In one example, the tightening member 6 includes a tightening bolt, by which the first movable portion 34 can be tightened on the X-axis linear guide 311, thereby playing a locking role. By unscrewing the tightening bolt, the first movable portion 34 can be released, so that the first movable portion 34 can slide along the X-axis linear guide 311. As a result, after the Y-axis linear guide 312 slides to a suitable position on the X-axis linear guide 311 through the first movable portion 34, the first movable portion 34 is tightened on the X-axis linear guide 311 by using the tightening bolt, thereby also playing a locking role on the position of the Y-axis linear guide 312. Of course, the tightening bolt can also be provided with a handle, etc., to facilitate the operation of the tightening bolt. The tightening member 6 can also be other structures such as elastic pins or buckles, etc., which are not specifically limited in this embodiment.

[0056] Please refer to Figure 4As shown, in some embodiments, the descending part 32 and the hot spot jig 33 are installed as a whole and are arranged in two groups. The two groups of hot spot jigs 33 and the two groups of glass lifting mechanisms 2 are arranged one by one, that is, each set of hot spot jigs 33 can respectively perform hot film hot spot operations on the glass sheet 5 at the position supported by the glass lifting mechanism 2. The upper end of the descending part 32 is slidably connected to the Y-direction linear guide 312 through the second moving part 35, specifically, it is slidably connected to the transverse part 3122 of the Y-direction linear guide 312, and the lower end of the descending part 32 is connected to the hot spot jig 33. Therefore, by sliding the descending part 32 along the transverse part 3122, the position of the hot spot jig 33 along the short side direction W of the cutting machine table 1 can be adjusted to adapt to the width of the glass sheet 5 or the change of the stop position of the glass sheet 5.

[0057] Preferably, the second moving part 35 is slidably provided on the transverse part 3122, and the upper end of the descending part 32 is connected to the second moving part 35, so that the descending part 32 can reciprocate along the length direction of the transverse part 3122 through the second moving part 35. Here, by adopting the cooperation between the second moving part 35 and the Y-axis linear guide rail 312, the descending part 32 is more stable when moving.

[0058] In one example, the descending part 32 is configured as a cylinder, the cylinder body of the cylinder is connected to the second moving part 35, and the telescopic rod of the cylinder is vertically arranged downward and used to connect the hot spot fixture 33. In addition, the cylinder in this embodiment uses a pen-shaped cylinder with a cylinder diameter of 32 mm. According to calculations as shown in Table 1, when the air pressure of the cylinder is set at 0.15MPa-0.6MPa, the theoretical pressure is correspondingly set at 12Kg-48Kg. This range can be adjusted according to actual conditions, but due to friction and other conditions, the actual pressure may be less than the theoretical pressure. Therefore, the operating pressure of the cylinder can be reasonably set according to the actual needs of the hot spot operation.

[0059] Table 1

[0060]

[0061] Therefore, in this embodiment, through the setting of the X-axis linear guide 311, the Y-axis linear guide 312 can slide in the left and right direction (the long side direction L of the cutting machine 1) to adjust the position of the hot spot jig 33 in the left and right direction, thereby adapting to the change of the length of the glass sheet 5 or the stop position of the glass sheet 5; at the same time, the descending part 32 can also slide in the front and back direction (the short side direction W of the cutting machine 1) on the Y-axis linear guide 312, thereby adapting to the change of the stop position of the glass sheet 5 or the width of the glass sheet 5. Through the mutual cooperation of the X-axis linear guide 311 and the Y-axis linear guide 312, the position of the hot spot jig 33 can be flexibly adjusted to adapt to glass sheets 5 and adhesive films of different sizes.

[0062] In this embodiment, in order to facilitate the hot spot fixture 33 to be more stable when it is descending or ascending, a Z-direction linear guide 36 is also arranged between the hot spot fixture 33 and the second moving part 35. The Z-direction linear guide 36 includes a static guide 361 and a dynamic guide 362. The static guide 361 is arranged in two groups. The two groups of static guides 361 are respectively located on both sides of the second moving part 35 and extend vertically downward. The dynamic guide 362 is arranged to correspond to the static guide 361, that is, the upper end of the dynamic guide 362 slides on the static guide 361, and the lower end of the dynamic guide 362 is used to connect the hot spot fixture 33. Thus, the hot spot fixture 33, the dynamic guide 362 and the descending part 32 are a whole. When the descending part 32 controls the hot spot fixture 33 to descend, the dynamic guide 362 slides with the static guide 361 as a guide. Therefore, through the coordinated arrangement of the dynamic guide 362 and the static guide 361, the hot spot fixture 33 is stable when it ascends and descends.

[0063] Please refer to Figure 4 , Figure 6 As shown, in this embodiment, it should be noted that since the number of the hot spot jigs 33 is not fixed, two are set in this embodiment. Therefore, in order to facilitate the use of one descending part 32 to simultaneously control the descending operation of multiple hot spot jigs 33, a mounting profile 37 is added between the descending part 32 and the hot spot jig 33 in this embodiment. Multiple hot spot jigs 33 can be directly mounted on the lower surface of the mounting profile 37 and distributed along the length direction of the mounting profile 37. At the same time, the lower end of the moving guide rail 362 is connected to the lower surface of the mounting profile 37. In this way, the output end of the descending part 32 can act on the upper surface of the mounting profile 37, and the hot spot operation is realized by pressing down with multiple hot spot jigs 33 through the mounting profile 37.

[0064] In one example, the hot point mechanism 3 further includes a floating joint 38 and an elastic buffer 39, which are arranged between the output end of the descending part 32 and the mounting profile 37, the output end of the descending part 32 is connected to the upper end of the floating joint 38, the lower end of the floating joint 38 is connected to the upper end of the elastic buffer 39, and the lower end of the elastic buffer 39 is mounted on the mounting profile 37. The floating joint 38 is used to connect two shafts in different mechanisms, such as the driving shaft and the driven shaft, so that they rotate together to transmit torque; on the other hand, it is used to eliminate errors, especially in some high-speed and heavy-load use environments, the output of the power mechanism such as the cylinder is relatively large, if the direction of the force and the force point of the power mechanism are not on the same line when the power mechanism is extended, the shaft rod is easy to deform, one end of the floating joint 38 is floating, which can be used to absorb or correct the lateral force, realize flexible connection, even if there are some dimensional deviations, it is not a big problem, protect the relevant components and make the equipment run smoothly, and extend the service life of the equipment. In this embodiment, since the hot spot fixture 33 is relatively hard, a floating joint 38 is selected to be added between the hot spot fixture 33 and the descending part 32 to perform a soft hot spot action to ensure that the glass sheet 5 will not be cracked, damaged or even broken. For example, when the descending part 32 is a cylinder and the telescopic rod of the cylinder vibrates or deforms, the floating joint 38 can reduce the deformation of the telescopic rod and absorb the displacement, vibration and thermal expansion of the telescopic rod during the operation of the telescopic rod. Compared with the method in which the telescopic rod of the cylinder is directly rigidly connected to the hot spot fixture 33, the floating joint 38 in this embodiment is composed of a movable compensator, a hydraulic cylinder, a ball head, a flange, etc., which can reduce the deformation and vibration of the system pipeline during the operation of the pipeline. A rubber pad or a steel ball is usually arranged inside the hot spot fixture 33 to play a role in buffering and shock absorption. When the structure vibrates or deforms, it can move or deform accordingly, thereby protecting the structure from damage. By using an elastic buffer 39, the hot spot fixture 33 can also play a role in buffering and shock absorption when applying pressure to the glass sheet 5.

[0065] In one example, the elastic buffer 39 includes an upper plate 391, a lower plate 392, an elastic member 393 and a guide column 394. The lower plate 392 is mounted on the upper surface of the mounting profile 37. The upper plate 391 and the lower plate 392 are arranged opposite to each other and are located on the same side of the mounting profile 37. The lower end of the floating joint 38 is connected to the upper plate 391. The lower end of the guide column 394 is connected to the lower plate 392, and the upper end is passed through the upper plate 391. The upper plate 391 can be pressed down along the guide column 394. The elastic member 393 is arranged between the upper plate 391 and the lower plate 392 and sleeved on the guide column 394. Thus, the force applied to the floating joint 38 by the descending part 32 is then transmitted to the upper plate 391 by the floating joint 38, so that the upper plate 391 is pressed down, and the elastic member 393 is squeezed while being pressed down, thereby achieving the effect of elastic buffering.

[0066] Please refer to Figure 7 As shown, in this embodiment, it should be noted that the hot point fixture 33 in this embodiment uses two groups of hot point heads 331 at each end, and each group of hot point heads 331 has four hot points, and the hot points are round points with a diameter of 6 mm, so as to ensure that the hot point pulling force meets the requirements. The hot point fixture 33 is also provided with a heating tube 332 and a thermocouple 333. The hot point heads 331 are heated by the heating tube 332, and the temperature is transferred by the thermocouple 333, which is used to monitor the heating temperature of the hot point heads 331, so as to control the heating temperature and ensure that the glass sheet 5 will not be cracked or damaged. Preferably, the hot point fixture 33 is made of copper, and the edges of the hot point fixture 33 are rounded. Because the hot point fixture 33 is made of copper block material, the force during hot point is relatively hard, so the hot point fixture 33 is designed and processed with rounded edges to prevent the sharp edges from causing the film to break.

[0067] In this embodiment, a welding method for a film cutting machine is also provided, which is applied to the above-mentioned film cutting machine. The film cutting machine includes a cutting machine table 1, a glass lifting mechanism 2 and a hot spot mechanism 3. Figure 8 As shown, the method comprises the following steps:

[0068] Step S201: Control the cutting machine 1 through the controller 4 to receive the glass sheet 5 transmitted from the assembly line and transfer it to a predetermined position;

[0069] Specifically, step S201 includes: receiving the glass sheet 5 transmitted from the assembly line through the cutting machine 1, and advancing to the position where the photoelectric sensor reaches; when the photoelectric sensor is blocked, sending a notification signal to the controller 4;

[0070] The controller 4 receives the notification signal and controls the cutting machine 1 to stop conveying, so that the glass sheet 4 reaches a predetermined position.

[0071] In the present embodiment, it should be noted that the glass sheet 5 first flows into the cutting machine 1 through the production line, the cutting machine 1 receives the glass sheet 5 transmitted from the production line, and advances to the position where it reaches the photoelectric sensor. The photoelectric sensor (the sensing position of the photoelectric sensor is the configuration position of the sensing element of the photoelectric sensor) is used to send a notification signal to the controller 4 when the corresponding sensing element is blocked, that is, when the glass sheet 5 advances to the sensing element that blocks the photoelectric sensor, the photoelectric sensor sends a notification signal to the controller 4. The controller 4 receives the notification signal and controls the cutting machine 1 to stop conveying. At this time, the glass sheet 4 reaches the predetermined position and generates a stop signal. This stop signal is used to feedback control the subsequent lifting and film cutting actions of the glass lifting mechanism 2; if the glass sheet 5 is misaligned during the stopping process, the correction mechanism in the cutting machine 1 will also correct the glass sheet 5 to the center position.

[0072] Step S202: the controller 4 controls the glass lifting mechanism 2 to rise until it contacts and supports the bottom surface of the glass sheet 5, and the controller 4 controls the cutting machine 1 to cut and lay the glass sheet 5;

[0073] Specifically, step S202 includes: the photoelectric sensor sends a stop signal to the controller 4 in response to the glass sheet 5 stopping conveying, the controller 4 receives the stop signal, and controls the glass lifting mechanism 2 to rise to contact and support the bottom surface of the glass sheet 5 at a predetermined position; at the same time, controls the cutting machine 1 to cut and lay the glass sheet 5 with adhesive film.

[0074] In this embodiment, it should be noted that after receiving the above-mentioned stop signal, the controller 4 controls the glass lifting mechanism 2 to rise to contact and support the bottom surface of the glass sheet 5 at the predetermined position, and supports the bottom surface below the middle of the long side of the glass sheet 5 through the glass lifting mechanism 2. At the same time, the controller 4 also controls the cutting machine 1 to cut and lay the glass sheet 5 with adhesive film, and generates a hot spot signal.

[0075] Step S203: the controller 4 controls the hot spot mechanism 3 to descend and implements the hot spot operation on the glass sheet 5 at the position supported by the glass lifting mechanism 2;

[0076] In the present embodiment, it should be noted that the cutting machine 1 triggers a hot spot signal while cutting and laying the adhesive film on the glass sheet 5. The controller 4 receives the hot spot signal and controls the hot spot mechanism 3 to descend while the film clamping mechanism is retracted. The hot spot mechanism 3 performs the hot spot operation on the adhesive film at a position where the glass sheet 5 is supported by the glass lifting mechanism 2. After the hot spot operation is completed, a signal for the glass sheet 5 to flow out is triggered, and the glass sheet 5 flows out, and this action is repeated.

[0077] The implementation principle of this embodiment is as follows: after the glass sheet 5 reaches the predetermined position in the cutting machine 1, the glass lifting mechanism 2 lifts and fits the lower surface of the glass sheet 5, and the adhesive film is laid at this time. The hot pressing signal is triggered during the laying action, and the hot pressing mechanism 3 is pressed down synchronously and hot presses the adhesive film and the glass sheet 5 together to ensure that they will not be offset. The hot pressing is performed while the adhesive film is laid. After the adhesive film is cut by the cutting machine 1, there is no need to move the work station. Through the automatic hot pressing operation of the hot pressing mechanism 3, it will not be offset, thereby improving accuracy, saving manpower, improving production process efficiency, and gradually realizing workshop automation.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
