[0032] Reference Figures 1 to 4 An embodiment of the present application provides a clamping device 100 for clamping the adhesive film 10 of a photovoltaic module. The clamping device 100 includes a lower pressing plate 101, a suction portion 102 and a clamping portion 103, wherein the lower pressing plate 101 is configured to be movable in the vertical direction, the suction portion 102 is disposed on the lower pressing plate 101 to absorb the adhesive film 10, and the clamping portion 103 is configured to be movable in the horizontal direction to below the lower pressing plate 101 and clamp the adhesive film 10.
[0033] The EVA film 10 is usually rolled into a cylindrical shape, and the cutting machine needs to clamp and pull out a certain length of film, such as 20 cm, for subsequent cutting, punching, and joining operations. However, the ultra-light weight film is thin, soft, and light, resulting in natural sagging at the cut of the rolled film. Therefore, the clamping structure of the cutting machine cannot clamp the film. Figures 1 to 4 As shown, in the clamping device 100 provided in the embodiment of the present application, the suction portion 102 can move in the vertical direction along with the lower pressure plate 101 and generate suction, thereby sucking the end of the adhesive film 10 to prevent the adhesive film 10 from sagging, and the clamping portion 102 can move in the horizontal direction to below the lower pressure plate 101, thereby clamping the adhesive film 10, without the need for manual intervention, without affecting the production efficiency of the cutting machine, and at the same time without increasing the labor intensity of the operator and avoiding safety accidents.
[0034] Reference Figure 3 and Figure 4 In some embodiments of the present application, there are multiple suction parts 102 , and the multiple suction parts 102 are evenly arranged on the lower pressing plate 101 along the width direction of the adhesive film 10 .
[0035] Since the EVA film 10 has a certain width, the number of suction parts 102 of the clamping device 100 provided in the embodiment of the present application is set to be multiple, and extend along the width direction of the film 10, so that when the lower pressure plate 101 is pressed down, the multiple suction parts 102 can completely absorb the film 10 at the incision, ensuring that the film 10 can be completely sucked, so that the clamping part 102 can completely clamp the film 10 at the incision, thereby facilitating subsequent operations.
[0036] Refer again Figure 2 In some embodiments of the present application, the suction part 102 includes a telescopic rod 121, a spring 122 and a suction cup 123, the spring 122 is sleeved on the telescopic rod 121, the suction cup 123 is connected to one end of the telescopic rod 121, and the telescopic rod 121 is fixedly connected to the lower pressure plate 101.
[0037] Specifically, the suction cup 123 of the suction part 102 is used to generate suction. In the clamping device 100 provided in the embodiment of the present application, the suction cup 123 generates suction by mechanical means, thereby sucking the film 10 at the cut, that is, when the suction part 102 is pressed down with the lower pressing plate 101, the suction cup 123 abuts against the loading platform that carries the film 10, thereby generating suction under the action of the pressure applied by the lower pressing plate 101, and at the same time, the telescopic rod 121 and the spring 122 will shrink. When the suction cup 123 sucks the film 10, the lower pressing plate 101 moves upward, and the telescopic rod 121 moves downward under the action of the spring 122, thereby completely sucking the film 10. The clamping device provided in the embodiment of the present application has a simple structure and low manufacturing cost through the above settings.
[0038] It should be noted that the suction force of the suction cup 123 can also be generated by other means, such as an electric vacuum suction cup, etc. The specific form shall be based on actual needs and is not limited here.
[0039] Reference Figure 2 In some embodiments of the present application, the lower pressing plate 101 is L-shaped, and the lower pressing plate 101 includes a long side 111 and a short side 112. The short side 112 is connected to one end of the long side 111. The long side 111 extends in the vertical direction, and the short side 112 extends in the horizontal direction. The telescopic rod 121 of the suction part 102 is fixed on the long side 111, and a through hole 113 is provided on the short side 112. The suction cup 123 of the suction part 102 protrudes from the through hole 113 toward the direction of the film 10.
[0040] Specifically, Figure 2As shown, the suction part 102 is fixed to the side of the long side 111 of the lower pressing plate 101 facing the clamping part 103 , and a through hole 113 is provided on the short side of the lower pressing plate 101 . The suction cup 123 of the suction part 102 protrudes from the through hole 113 toward the adhesive film 10 . When the suction part 102 is pressed down along with the lower pressure plate 101, the suction cup 123 rests on the loading platform carrying the adhesive film 10, so that under the action of the pressure applied by the lower pressure plate 101, the telescopic rod 121 and the spring 122 will shrink until the suction cup 123 is flush with the short side 112 of the lower pressure plate 101. After the suction cup 123 sucks the adhesive film 10, the lower pressure plate 101 moves upward, and the telescopic rod 121 moves downward under the action of the spring 122, and the suction cup 123 protrudes from the through hole 113. There is a height difference between the suction cup 123 and the short side 112 of the lower pressure plate 101, which makes it easy for the clamping part 103 to extend to the bottom of the lower pressure plate 101 and clamp the adhesive film 10, thereby ensuring that the clamping part 103 can clamp the adhesive film 10, thereby completing the subsequent operation of the adhesive film 10.
[0041] Reference Figure 2 and Figure 3 In some embodiments of the present application, the clamping portion 103 includes an inner roller 131, an outer roller 132, an upper clamping jaw 133 and a lower clamping plate 134. The outer roller 132 is sleeved on the inner roller 131. The rotation directions of the outer roller 132 and the inner roller 131 are opposite. The upper clamping jaw 133 is connected to the inner roller 131, and the lower clamping plate 134 is connected to the outer roller 132.
[0042] For example, the inner roller 131 can be set to move clockwise, and the outer roller 132 can be set to move counterclockwise. When the suction part 102 completes the suction operation of the film 10, the suction cup 123 of the suction part 102 protrudes from the through hole 113 of the lower pressing plate 101, and the clamping part 103 moves to the bottom of the lower pressing plate 101. The upper clamping claw 133 and the lower clamping plate 134 are driven by the inner roller 131 and the outer roller 132 respectively, and clamp the ends of the film 10 from the top and bottom, and pull the film 10 out for subsequent cutting and other operations. Through the above settings, the embodiment of the present application can ensure that the film 10 is firmly clamped, without manual intervention, and will not affect the production efficiency of the cutting machine. At the same time, it can not increase the labor intensity of the operator and can avoid safety accidents.
[0043] In some embodiments of the present application, a side edge of the upper clamping jaw 133 is provided with an avoidance hole (not shown), and the size of the avoidance hole is larger than the size of the suction cup 123 of the suction portion 102 .
[0044] When the suction part 102 completes the suction operation of the adhesive film 10, the suction cup 123 of the suction part 102 protrudes from the through hole 113 of the lower pressing plate 101, and the clamping part 103 moves to the bottom of the lower pressing plate 101. Due to the existence of the avoidance hole, the upper clamping jaw 133 can extend between the lower pressing plate 101 and the adhesive film 10, thereby ensuring that the upper clamping jaw 133 can cooperate with the lower clamping plate 134 to clamp the adhesive film 10, and pull the adhesive film 10 out for subsequent cutting and other operations. Through the above arrangement, the embodiment of the present application can ensure that the adhesive film 10 is firmly clamped without manual intervention, will not affect the production efficiency of the cutting machine, and can also not increase the labor intensity of the operator, and can avoid safety accidents.
[0045] Refer again Figure 3 In some embodiments of the present application, there are multiple upper clamping jaws 133 , and the multiple upper clamping jaws 133 are evenly connected to the inner roller 131 along the width direction of the adhesive film 10 .
[0046] Since the EVA film 10 has a certain width, the number of upper clamping jaws 133 of the clamping device 100 provided in the embodiment of the present application is set to be multiple, and extends along the width direction of the film 10, so that when the lower pressure plate 101 is pressed down, the multiple upper clamping jaws 133 can completely clamp the film 10 at the incision, ensuring that the clamping part 102 can completely clamp the film 10 at the incision, thereby facilitating subsequent operations.
[0047] Reference Figure 2 In some embodiments of the present application, the upper clamp 133 includes an upper fixed section 133a, an upper connecting section 133b and an upper parallel section 133c, the upper fixed section 133a is fixed on the inner roller 131, the upper connecting section 133b is connected between the upper fixed section 133a and the upper parallel section 133c, and the upper parallel section 133c extends in the horizontal direction, and the lower clamp 134 includes a lower fixed section 134a, a lower connecting section 134b and a lower parallel section 134c, the lower fixed section 134a is fixed on the outer roller 132, the lower connecting section 134b is connected between the lower fixed section 134a and the lower parallel section 134c, and the lower parallel section 134c extends in the horizontal direction.
[0048] The fixed section 133a of the upper clamping jaw 133 is fixed on the inner roller 131, the upper connecting section 133b is connected between the upper fixed section 133a and the upper parallel section 133c, and the upper parallel section 133c extends in the horizontal direction. The lower fixed section 134a of the lower clamping plate 134 is fixed on the outer roller 132, the lower connecting section 134b is connected between the lower fixed section 134a and the lower parallel section 134c, and the lower parallel section 134c extends in the horizontal direction. When the inner roller 131 and the outer roller 132 rotate, the upper parallel section 133c of the upper clamping jaw 133 and the lower parallel section 134c of the lower clamping plate will be driven to move toward each other, thereby clamping the adhesive film 10. Through the above arrangement, the embodiment of the present application can increase the area of the clamping surface between the upper clamping jaw 122 and the lower clamping plate 134, thereby ensuring that the adhesive film 10 is completely clamped.
[0049] Reference Figures 2 to 4 In some embodiments of the present application, the clamping device 100 further includes a pull rod 104, the clamping portion 102 is fixed on the pull rod 104, the end of the pull rod 104 is provided with a mounting hole 141, and the end of the inner roller 131 is arranged in the mounting hole 141. The function of the pull rod 104 is to fix the inner roller 131 and the outer roller 132, and when the film 10 is clamped, the pull rod 104 will drive the clamping portion 102 to move in the horizontal direction, thereby pulling the film 10 to move, so as to perform subsequent cutting and other operations.
[0050] Therefore, the operation process of the clamping device 100 provided in the embodiment of the present application is as follows: first, the lower pressing plate 101 moves to the end of the adhesive film 10, and the suction part 102 can move in the vertical direction with the lower pressing plate 101 and generate suction, thereby sucking one end of the adhesive film 10 to prevent the adhesive film 10 from sagging, and the clamping part 102 can move in the horizontal direction to below the lower pressing plate 101, and the upper clamping claw 133 and the lower clamping plate 134 of the clamping part 102 are driven by the inner roller 131 and the outer roller 132 respectively, and clamp the ends of the adhesive film 10 from above and below respectively. Finally, the pull rod 104 will drive the clamping part 102 to move in the horizontal direction, thereby pulling the adhesive film 10 to move, so as to perform subsequent cutting and other operations, without the need for manual intervention, and will not affect the production efficiency of the cutting machine. At the same time, it will not increase the labor intensity of the operator and can avoid safety accidents.
[0051] The embodiment of the present application also provides a cutting machine, including a clamping device 100 as described above. The specific structure of the clamping device 100 refers to the above embodiment. Since the clamping device 100 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
[0052] In the cutting machine provided in the embodiment of the present application, the suction part 102 of the clamping device 100 can move in the vertical direction with the lower pressure plate 101 and generate suction, thereby sucking the end of the adhesive film 10 to prevent the adhesive film 10 from sagging, and the clamping part 102 can move to the bottom of the lower pressure plate 101 in the horizontal direction, thereby clamping the adhesive film 10 for subsequent cutting and other operations without manual intervention, without affecting the production efficiency of the cutting machine, and at the same time without increasing the labor intensity of the operator and avoiding safety accidents.
