Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel film pasting, in particular to a multi-directional film strip laying device with symmetrical feeding. Background Art

[0002] In the current field of solar photovoltaic module production and processing, with the continuous improvement of production intensity and usage demand, people have also put forward higher requirements on the structure and performance of solar photovoltaic modules.

[0003] In the existing solar photovoltaic module processing and production process, in order to avoid short circuit after the busbars are overlapped together, they need to be isolated from the EVA by the backboard strips, and the outside of the busbar part is bonded to the backboard strips by EVA (ethylene-vinyl acetate copolymer) strips.

[0004] In order to cater to the use of multiple working conditions, large film rolls are usually used for film application in the market, so that the large film can cover the photovoltaic panel, and the cut strip film can cover the edge of the photovoltaic panel. However, this method requires that a structure that can pull out the large film and a structure that can cut the strip film be set on one device at the same time, and the equipment structure is complex and the operation is cumbersome. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a multi-directional strip film laying equipment with symmetrical loading. Two sets of identical loading structures and clamping claw structures can be used for two sets of opposite sides of the same photovoltaic panel, and the film can be applied to four edges at the same time. There is no need to cut large rolls of film, which simplifies the film application steps.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A multi-directional film strip laying device with symmetrical feeding, a film laminating machine main body, a photovoltaic panel placement position is reserved in the middle of the film laminating machine main body, and feeding devices are symmetrically arranged at the top corners of two opposite sides of the photovoltaic panel placement position,

[0008] The feeding device comprises:

[0009] The loading rack is connected to the main body of the film laminating machine.

[0010] The material rolls are arranged in layers on the loading rack.

[0011] The material changing clamps are slidably connected to the side wall of the loading frame; the material changing clamps on both sides are located on the opposite back sides of the loading frame where they are located.

[0012] The main body of the film laminating machine is provided with two groups of material taking and placing clamps, and the two groups of material taking and placing clamps are respectively connected to the two groups of material changing clamps; the main body of the film laminating machine is also provided with a cross frame, and the movement paths of the two groups of material taking and placing clamps cover the side walls and the cross frame of the main body of the film laminating machine.

[0013] As a further improvement of the above technical solution:

[0014] Two sets of material taking and placing clamping claws are symmetrically arranged on the main body of the film laminating machine.

[0015] A material taking and discharging track is arranged on the side wall of the main body of the film laminating machine, a horizontal frame is slidably connected to the material taking and discharging track, a lifting device is arranged on the horizontal frame, and the lifting device drives a displacement track which is perpendicular to the material taking and discharging track.

[0016] At least one set of the material taking and placing clamping claws on both sides can slide on the displacement track.

[0017] The material taking and placing clamping claw itself can be rotatably arranged; the material taking and placing clamping claw sliding on the displacement track can rotate relative to the cross frame.

[0018] A material changing slide rail is arranged on the side wall of the feeding frame, and the material changing clamping claw is slidably connected to the material changing slide rail.

[0019] The material rolls used by the loading racks on both sides have the same width.

[0020] The film strip cutting position is between the feeding device and the main body of the film laminating machine.

[0021] The material changing jaws and material taking and placing jaws on both sides work independently of each other.

[0022] The beneficial effects of the utility model are as follows:

[0023] The utility model has a compact and reasonable structure and is easy to operate. Its greatest advantage is that the four sides of the photovoltaic panel are grouped, with two opposite sides forming a group. Each group of opposite sides is equipped with a feeding device to pull and feed the film tape.

[0024] Since the structures on both sides are completely the same, the applicability of the single-sided loading device and the single-sided clamp is improved during the actual production or assembly of the equipment, and a pre-assembly method can be adopted to reduce the complexity of the equipment itself.

[0025] At the same time, since the specifications of each batch of photovoltaic panels may be different, the two sets of feeding devices and clamps no longer need to limit which side to cut. The side to be attached can be directly selected according to the expected length of the film tape, reducing the limitations of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] A material taking and putting track 5 is provided on the side wall of the main body 1 of the film laminating machine, and the cross frame 4 is slidably connected to the material taking and putting track 5.

[0042] A lifting device 6 is provided on the horizontal frame 4 , and the lifting device 6 drives a displacement track 7 which is perpendicular to the material taking and placing track 5 .

[0043] At least one set of the material taking and placing clamping jaws 3 on both sides can slide on the displacement track 7 .

[0044] The material taking and placing clamping jaw 3 itself can be rotatably arranged; the material taking and placing clamping jaw 3 sliding on the displacement track 7 can rotate relative to the cross frame 4.

[0045] A material changing slide rail 8 is provided on the side wall of the loading frame 201 , and the material changing clamping claw 203 is slidably connected to the material changing slide rail 8 .

[0046] The material rolls 202 used by the loading racks 201 on both sides have the same width.

[0047] The film strip cutting position is located between the feeding device 2 and the film laminating machine body 1 .

[0048] The material changing jaws 203 and the material taking and placing jaws 3 on both sides work independently of each other.

[0049] The specific structure and working principle of the utility model are as follows:

[0050] Aiming at the working condition of sticking film strips on the edges of rectangular photovoltaic panels, the utility model proposes a film sticking device with symmetrical feeding structures on both sides. The main improvement lies in the use of a simpler feeding structure to stick film strips of corresponding lengths onto the photovoltaic panels.

[0051] The specific structure and working principle of the utility model are as follows:

[0052] like Figure 1 As shown, the whole machine structure includes a film laminating machine body 1 for laying photovoltaic panels flat. The photovoltaic panels to be filmed are placed in the middle of the film laminating machine body 1. Photovoltaic panels are mostly rectangular and have four sides that need to be filmed. If the photovoltaic panels are relatively large in length and width, film strips need to be added in the middle to form a sun-shaped film strip frame.

[0053] Different from the large film rolls used in conventional technologies, the present invention adopts two groups of feeding devices 2 for small film strips, which are used to attach horizontal and vertical film strip frames respectively.

[0054] Since there are many specifications of photovoltaic panels and the side lengths of each specification are different, the placement position of the long and wide sides of the first batch may change the position of the long sides when the second batch of photovoltaic panels are filmed. Therefore, this solution provides two sets of feeding devices 2 with the same structure and symmetrically arranged at the two top corners of the photovoltaic panels.

[0055] The structure of the feeding device 2 is as follows: Figure 2 As shown, Figure 2 In Figure 1 The feeding device 2 at the upper left position of the center is taken as an example for explanation.

[0056] Each loading device 2 includes a loading frame 201, on the side of which a material changing slide rail 8 is arranged, and a material changing clamp 203 is slidably connected to the material changing slide rail 8. The material changing clamp 203 is used to clamp the material head of the material roll 202 and then pull it to the subsequent film laminating machine body 1, and the material is received by the material taking and releasing clamp 3 on the film laminating machine body 1 to complete the attachment.

[0057] Since the main problem to be solved by this solution is to be able to use two sets of loading devices 2 and picking and placing clamps 3 to perform frame film pasting for different long and short sides, the loading device 2 and the picking and placing clamps 3 are each responsible for conveying the film strip forward in a straight line and driving the film strip to move parallel or rotationally onto the photovoltaic panel.

[0058] That is to say, the loading device 2 only needs to output the film tape in a straight line. The material taking and discharging clamps 3 on both sides, taking the left and right sides as an example, the left material taking and discharging clamps 3 and the right material taking and discharging clamps 3 can both slide forward and backward in a straight line on the corresponding material taking and discharging tracks 5 on the side walls of the film laminating machine body 1, can also slide vertically on the displacement tracks 7, and can also rotate by themselves and be driven by the lifting device 6. The lifting device 6 used in this embodiment can be an existing device such as a cylinder, an electric cylinder, etc., which will not be described in detail here.

[0059] For example, after a batch of photovoltaic panels are placed, the left-side material picking and placing clamp 3 drives the film belt to move along the material picking and placing track 5 to the side of the photovoltaic panel; then it moves along the displacement track 7 to the top of the film pasting position, and the lifting device 6 drives it to press down to complete the film pasting;

[0060] The right-side material picking and unloading clamp 3 drives the film belt and moves along the material picking and unloading track 5 to the side of the photovoltaic panel; it rotates to a state perpendicular to the material picking and unloading track 5, and is parallel to the other opposite sides to be filmed; it moves again along the material picking and unloading track 5 and the displacement track 7 to the top of the position to be filmed, and the lifting device 6 drives the downward pressure to complete the filming.

[0061] The above steps can also be performed by the left side taking and placing material clamping jaw 3 rotating and displacing the film, and the right side taking and placing material clamping jaw 3 displacing the film. This is also the purpose of adopting a symmetrical structure in this solution, that is, to improve versatility.

[0062] In this solution, the same horizontal frame 4 is also used to integrally mount the material taking and placing clamps 3 on both sides, thereby simplifying the equipment.

[0063] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
