[0002] Due to its flexibility, shock absorption, slip resistance, and pressure resistance, EVA material is widely used in various fields, such as shoe soles, interior materials, packaging films, gaskets, medical devices, hot melt adhesives, and cable insulation layers. EVA material is also adhered to photovoltaic modules for protection.

[0003] EVA strips are strip-shaped components that need to be cut into sheets to form EVA films, which are then fixed onto photovoltaic modules. The EVA films have through-holes. These through-holes protect the periphery of the leads, which then pass through them.

[0004] If EVA strips are manually cut into sheets and then punched, the process is not only labor-intensive but also inefficient. Therefore, devices for manufacturing EVA sheets have been developed, including sheet punching and cutting mechanisms, sheet handling mechanisms, alignment and loading mechanisms, labeling mechanisms, sheet straightening machines, and label printers. These devices are not only numerous and complex in structure, and costly, but also occupy a large space, making them inconvenient to install, carry, and transport. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0030] See Figure 1-4 This utility model discloses an EVA film manufacturing device, including a feeding mechanism 1 and a punching zone, wherein the feeding mechanism 1 is used to provide adhesive strips 100 into the punching zone.

[0031] The punching area is equipped with a punching drive mechanism 2, a punching component 21, a cutting drive mechanism 3, and a cutting blade 31. The punching drive mechanism 2 and the punching component 21 are connected to drive the punching component 21 to punch holes in the adhesive strip 100. The cutting drive mechanism 3 and the cutting blade 31 are connected to drive the cutting blade 31 to cut the adhesive strip 100 to form an adhesive sheet 200.

[0032] This utility model of EVA film manufacturing device includes a feeding mechanism and a punching zone. The feeding mechanism continuously supplies adhesive strips to the punching zone. Within the punching zone, the adhesive strips are punched by a punching drive mechanism that drives a punching component, and then cut by a cutting drive mechanism that drives a cutting blade to form the film, thus realizing the manufacturing of EVA film. It has few components, a simple structure, and low cost. Furthermore, it occupies little space, is small in size, and is easy to install, carry, and transport.

[0033] In some embodiments, the punching drive mechanism 2 and the cutting drive mechanism 3 are both cylinders, but this is not a limitation.

[0034] Specifically, such as Figure 1-2 As shown in Figure 4, a punching seat 4 is also provided in the punching area, and the punching drive mechanism 2 and the cutting drive mechanism 3 are both installed on the punching seat 4; the punching seat 4 is provided with a strip passage 41; the feeding mechanism 1 is used to provide the strip 100 into the strip passage 41; the punching drive mechanism 2 and the cutting drive mechanism 3 respectively drive the punching part 21 and the cutting blade 31 to move in the strip passage 41.

[0035] The feeding mechanism continuously supplies adhesive strips into the conveyor channel, causing the strips to be punched and cut into sheets, forming multiple sheets with through holes for use in photovoltaic modules. Specifically, the punching drive mechanism moves the punching component to punch the adhesive strips. The punched adhesive strips then move towards the cutting blade under the drive of the feeding mechanism. The cutting drive mechanism moves the cutting blade to cut the adhesive strips, forming sheets with through holes.

[0036] In some embodiments, such as Figure 4 As shown, the inner wall of the strip passage 41 is provided with a first guide groove 42 and a second guide groove 43, the punching part 21 is provided with a guide block 22, the guide block 22 is inserted into the first guide groove 42; the cutting blade 31 is inserted into the second guide groove 43.

[0037] To ensure the punching component moves in the designated direction and accurately punches the rubber strip, a first guide groove is provided on the inner wall of the passage corresponding to the punching component. The first guide groove and the guide block cooperate to prevent the punching component from deviating and to provide sufficient punching force for effective punching. To ensure the cutting blade moves in the designated direction and accurately cuts the rubber strip, a second guide groove is provided on the inner wall of the passage corresponding to the cutting blade. The cutting blade is inserted into the second guide groove on both sides to guide its movement, prevent deviation, and provide sufficient cutting force.

[0038] In some embodiments, such as Figure 4As shown, the punching seat 4 is provided with a first clearance hole 44, a second clearance hole 45, and a cavity 46. The first clearance hole 44 and the cavity 46 are connected. The first clearance hole 44 is correspondingly provided with the punching component 21, and the second clearance hole 45 is correspondingly provided with the cutting blade 31. The second clearance hole 45 and the cavity 46 are connected.

[0039] To ensure successful punching, a first clearance hole is provided on the punching base below the punching part. The punching part moves towards and inserts into the first clearance hole, punching a through hole in the rubber strip placed between the punching part and the first clearance hole. Similarly, to ensure successful cutting, a second clearance hole is provided on the punching base below the cutting blade. The cutting blade moves towards and inserts into the second clearance hole, cutting the rubber strip placed between the cutting blade and the second clearance hole.

[0040] In some embodiments, such as Figure 4 As shown, a collection box 47 is provided inside the cavity 46. The collection box is located below the first and second clearance holes to collect the punched and cut fragments.

[0041] Furthermore, such as Figure 2 , 4 As shown, the present invention also includes a material-retrieving mechanism for removing the film 200; the material-retrieving mechanism includes a material-retrieving cylinder 5 and a suction cup 51, the material-retrieving cylinder 5 and the suction cup 51 are connected to drive the suction cup 51 to approach the film 200, thereby absorbing the film 200.

[0042] The finished film needs to be removed from the manufacturing device for later use. This invention also includes a material-grabbing mechanism. Specifically, a material-grabbing cylinder drives a suction cup to descend, approach the film, and attract it. Then, the material-grabbing cylinder drives the suction cup to rise, thereby removing the finished film from the conveyor channel.

[0043] In some embodiments, such as Figure 1 , 4 As shown, this utility model also includes a feeding cylinder 6 installed on the punching base 4. The feeding cylinder 6 is connected to the picking mechanism to move the picking mechanism. The feeding cylinder drives the picking mechanism, causing the picking mechanism that picks up the film to move outside the production device, such as to a container for collecting film or a device for conveying film. After the picking mechanism puts down the film, the feeding cylinder drives the picking mechanism to reset, so that the picking mechanism can pick up the freshly made film again. This cycle repeats to realize the picking and feeding. Specifically, the feeding cylinder 6 is connected to the picking cylinder 5.

[0044] In some embodiments, the present invention further includes a residue blowing mechanism for blowing away residue on the punching seat 4, the residue blowing mechanism being installed on the punching seat 4, and the residue blowing mechanism and the material taking mechanism being arranged correspondingly.

[0045] During the punching and cutting process, some residue may remain in the feed channel. To prevent excessive residue accumulation in the feed channel from affecting the suction cup's ability to pick up the film, this invention also includes a residue-blowing mechanism. When the suction cup picks up the film from the feed channel, the residue-blowing mechanism activates, blowing air onto the original location of the film in the feed channel to blow the residue away. This invention also includes a position sensor to detect whether the suction cup has picked up the film. When the sensor detects that the film has been picked up, it sends a signal to the controller, which then activates the residue-blowing mechanism to remove the residue.

[0046] In some embodiments, such as Figure 1-2 As shown in Figure 4, the residue blowing mechanism includes an air nozzle 7 and an air source (not shown in the figure). The air nozzle 7 is connected to the air source and is located on one side below the suction cup 51. The air source provides gas, which is blown out through the air nozzle. The air nozzle blows air towards the location of the original film in the strip passage, thereby blowing up the residue in the strip passage.

[0047] It should be noted that the residue suction mechanism also includes an air pipe, a solenoid valve, and a pressure reducing valve. The air nozzle is connected to the air source through the air pipe, and the solenoid valve and pressure reducing valve are installed on the air pipe. The pressure reducing valve reduces the pressure of the gas, and the solenoid valve controls the gas flow, realizing intermittent blowing, that is, realizing the opening and closing of the residue blowing mechanism.

[0048] The specific structures of the material handling cylinder 5, suction cup 51, feeding cylinder 6, air nozzle 7, air source, solenoid valve and pressure reducing device can adopt existing technology structures, and will not be described in detail here.

[0049] In addition, such as Figure 1 , 3 As shown, the feeding mechanism 1 includes a linear motor module 11 and a gripper cylinder 12, the gripper cylinder 12 being used to grip the rubber strip 100. A linear motor module is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. The most commonly used linear motor types are flat plate type and U-slot type. The gripper cylinder utilizes a thin cylinder body with positioning pin holes machined on it to install grippers and actuating rods. When the piston rod is pushed upwards or downwards by compressed air, the grippers or actuating rod open and close via the actuating pins at the upper end of the piston rod. The specific structures of the linear motor module and gripper cylinder can adopt existing technology structures and will not be described in detail here.

[0050] The linear motor module 11 is connected to the gripper cylinder 12 to drive the gripper cylinder 12 to move. The gripper cylinder 12 first clamps the adhesive strip 100, and then the linear motor module 11 drives the gripper cylinder 12 to move towards the punching area, providing unpunched and uncut adhesive strips 100 to the punching part 21 and the cutting blade 31. Then, the gripper cylinder 12 releases the adhesive strip 100, and the linear motor module 11 drives the gripper cylinder 12 to move in the opposite direction, i.e., reset. Next, the gripper cylinder 12 clamps the adhesive strip 100 again, and the linear motor module 11 drives the gripper cylinder 12 to move towards the punching area again. This cycle repeats continuously, continuously providing adhesive strips to the punching area for punching and cutting to form several pieces of adhesive sheet 200.

[0051] Furthermore, such as Figure 1 As shown, this utility model also includes an unwinding mechanism for storing the adhesive strip 100. The unwinding mechanism, the feeding mechanism 1, and the punching area are arranged in sequence. The unwinding mechanism includes an unwinding base 81, an adhesive strip reel 82, a support plate 83, and a pressing member 84. The support plate 83 is disposed on the unwinding base 81, and the adhesive strip reel 82 and the pressing member 84 are disposed on the support plate 83. The adhesive strip reel 82 is used to carry the adhesive strip 100, and the pressing member 84 is used to limit the adhesive strip 100 on the unwinding base 81.

[0052] The adhesive strip reel is used to store adhesive strips. The adhesive strips are output from the reel by the movement of the gripper cylinder, which pulls the adhesive strips out of the reel. To prevent the adhesive strips from swaying between the reel and the gripper cylinder and thus hindering their transport, this invention also includes a pressure member that limits the adhesive strips on the unwinding base, allowing the adhesive strips to move between the pressure member and the unwinding base, ensuring stable transport of the adhesive strips.

[0053] Accordingly, see Figure 1-4 This utility model also discloses a photovoltaic module EVA film laying system, including a feeding mechanism (not shown in the figure) for providing battery strings and the aforementioned EVA film making device. The specific structure of the EVA film making device is as described above and will not be repeated here.

[0054] In summary, this utility model provides an EVA film manufacturing device and a photovoltaic module EVA film laying system, which has a simple structure and small size.

[0055] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
