Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module automation equipment technology, and in particular to an integrated mechanism for punching and cutting EVA gaskets. Background Technology

[0002] In the manufacturing process of photovoltaic solar panels, lamination is a core step to ensure the quality and long-term reliability of module encapsulation. However, the uneven structure of the welding area of ​​the L-shaped busbar used for current conduction can easily lead to insufficient filling of EVA encapsulation material, resulting in defects such as missing adhesive and affecting product reliability. To solve this problem, the industry commonly uses pre-cut and punched EVA blocks as "filler pads." These pads melt when heated during lamination, filling and supplementing adhesive gaps, making them an indispensable and necessary step in ensuring the lamination quality of photovoltaic modules.

[0003] However, the preparation of EVA gaskets relies on manual operation. Workers use simple tools such as scissors to manually cut and punch holes, forming a typical labor-intensive operation mode. Not only is the slow pace of manual operation severely out of sync with the high-speed automated production line, resulting in low production efficiency, but manual operation also makes it difficult to ensure the precise uniformity of the size, shape, and hole position of each gasket, leading to inconsistent glue application results.

[0004] Therefore, there is an urgent need to design an integrated punching and cutting mechanism for EVA gaskets to solve the problem that the preparation of EVA gaskets in the existing technology relies on manual labor. Utility Model Content

The punching and cutting assembly is located downstream of the feeding assembly and includes a punching mechanism for punching holes in the EVA strip, a cutting mechanism for cutting the film of the punched EVA strip into individual gaskets, and a clamping mechanism for clamping the EVA strip during the punching and cutting process. A clamping assembly, located downstream of the punching and cutting assembly, is used to clamp the EVA strip before material removal. The material-grabbing component is located above the clamping component and is used to pick up the individual pads.

[0007] Preferably, the feeding assembly includes a reel for mounting the EVA strip, and a feeding roller group consisting of several rollers is provided downstream of the reel.

In the case where the pressing block is pressing the EVA strip, the feeding drive drives the feeding plate to pull the EVA strip from the support plate to the punching and cutting assembly for a preset stroke. Then, the pressing drive drives the pressing block to rise and release the EVA strip, and the feeding drive drives the feeding plate to reset.

[0009] Preferably, the punching mechanism includes a punching punch for punching the EVA strip, and an upper die platform and a lower die platform for supporting and carrying the punching operation.

The second power source is used to drive the cutting blade to cut the film on the EVA strip downward to form an independent gasket. Multiple clamping mechanisms are provided and distributed around the punching mechanism and the cutting mechanism. Each clamping mechanism is equipped with a third power source, which is used to drive the clamping mechanism to clamp or release the EVA strip, thereby locally clamping the EVA strip during punching or cutting.

[0010] Preferably, the number of clamping mechanisms is three sets, which are respectively arranged adjacent to the input side and output side of the punching mechanism and the input side of the cutting mechanism.

[0011] Preferably, the clamping assembly includes a pressure base plate, and an upper pressure plate is provided above the pressure base plate. The upper pressure plate is equipped with a fourth power source. The punched EVA strip is transferred from the punching and cutting assembly to the clamping assembly.

[0019] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1 to 4 As shown, an integrated punching and cutting mechanism for EVA gaskets includes a feeding assembly 1, a clamping and feeding assembly 2, a punching and cutting assembly 3, a clamping assembly 4, and a picking assembly 5.

[0020] like Figure 1 As shown, the unloading assembly 1 includes a reel 11 for mounting and carrying the EVA strip 7. Downstream of the reel 11 is a unloading roller group 12 composed of several rollers, which is used to transport and tension the EVA strip 7. A photoelectric sensor 13 is also provided on one side of the unloading roller group 12 for detecting whether there is adhesive film on the EVA strip 7. The adhesive film on the EVA strip 7 is used to manufacture EVA gaskets.

[0021] like Figures 1 to 3 As shown, the clamping and feeding assembly 2 is located downstream of the discharging assembly 1 and includes a pressing mechanism 21 for pressing the EVA strip 7 and a feeding mechanism 22 for pulling and transmitting the EVA strip 7. The pressing mechanism 21 and the feeding mechanism 22 work together to intermittently pull the EVA strip 7.

[0022] The pressing mechanism 21 includes a pressing drive 211, the output end of which is connected to a pressing block 212. The pressing drive 211 drives the pressing block 212 to press the EVA material strip 7 below. The pressing drive 211 adopts a power mechanism that can drive linear conveying, preferably a cylinder.

[0023] The feeding mechanism 22 includes a feeding drive 221, a support plate 222 is disposed above the feeding drive 221, and a feeding plate 223 is connected to the output end of the feeding drive 221. The feeding plate 223 slides relative to the support plate 222. The feeding drive 221 adopts a power mechanism capable of driving linear conveying, preferably a cylinder.

[0024] In this configuration, with the pressure block 212 pressing the EVA strip 7, the feeding drive 221 drives the feeding plate 223 to pull the EVA strip 7 from the support plate 222 onto the punching and cutting assembly 3 by a preset stroke. Subsequently, the pressure drive 211 drives the pressure block 212 to rise and release the EVA strip 7, and the feeding drive 221 drives the feeding plate 223 to reset. The feeding drive 221 is configured to drive the feeding plate 223 to move by a preset stroke, which is adapted to the length of a single individual pad.

[0025] The punching and cutting assembly 3 is located downstream of the feeding assembly 2 and includes a punching mechanism 31 for punching holes in the EVA strip 7, a cutting mechanism 33 for cutting the film of the punched EVA strip 7 into individual pads, and a clamping mechanism 32 for clamping the EVA strip 7 during the punching and cutting process.

[0026] The punching mechanism 31 includes a punching punch 311 for punching EVA strip 7, and an upper die platform 312 and a lower die platform 313 for supporting and carrying the punching operation. The punching punch 311 is equipped with a first power source, which drives the punching punch 311 to punch EVA strip 7. The feeding plate 223 conveys EVA strip 7 to the lower die platform 313.

[0027] The cutting mechanism 33 includes a cutting blade 331, a cutting board 332 is provided below the cutting blade 331, and the cutting blade 331 is equipped with a second power source. The second power source is used to drive the cutting blade 331 to cut the film on the EVA strip 7 downward to form an independent pad.

[0028] Multiple clamping mechanisms 32 are provided and distributed around the punching mechanism 31 and the cutting mechanism 33. Each clamping mechanism 32 is equipped with a third power source, which drives the clamping mechanism 32 to clamp or release the EVA strip 7, thereby locally clamping the EVA strip 7 during punching or cutting. Specifically, there are three sets of clamping mechanisms 32, respectively located adjacent to the input and output sides of the punching mechanism 31 and the input side of the cutting mechanism 33. When the strip is in place, the third power source first drives the clamping mechanism 32 to firmly clamp the strip onto the processing platform, preventing the strip from shifting or wrinkling during the punching process.

[0029] The clamping assembly 4, located downstream of the punching and cutting assembly 3, is used to clamp the EVA strip 7 before material removal. The clamping assembly 4 includes a pressure base plate 41, and an upper pressure plate 42 is provided above the pressure base plate 41. The upper pressure plate 42 is equipped with a fourth power source. The punched EVA strip 7 is transferred from the punching and cutting assembly 3 to the clamping assembly 4. The fourth power source is used to drive the upper pressure plate 42 to lift and lower to partially clamp or release the EVA strip 7.

[0030] The material-picking assembly 5, located above the clamping assembly 4, is used to pick up individual gaskets. The material-picking assembly 5 includes a fixed mounting plate 51, on which a suction nozzle 52 is threaded. The suction nozzle 52 is equipped with a fifth power source, which drives the suction nozzle 52 to rise and fall relative to the mounting plate 51. After the upper pressure plate 42 presses the EVA strip 7, the fifth power source drives the suction nozzle 52 to descend relative to the mounting plate 51 to pick up the adhesive film (i.e., individual gasket) on the punched EVA strip 7.

[0031] The first, second, third, fourth, and fifth power sources all employ a power mechanism capable of driving linear transmission, preferably a cylinder.

[0032] The feeding assembly 1, the clamping and feeding assembly 2, the punching and cutting assembly 3, the clamping assembly 4, and the picking assembly 5 are all configured and installed on the mounting frame 6.

[0033] Working principle: Feeding and Inspection: EVA strip 7 is drawn out from reel 11, tensioned and guided by unloading roller group 12, and enters clamping and feeding assembly 2. Photoelectric sensor 13 continuously monitors whether there is adhesive film on EVA strip 7.

[0034] Intermittent feeding: First, the pressure drive 211 actuates, driving the pressure block 212 to press down, firmly pressing the EVA strip 7 onto the support plate 222. Next, the feeding drive 221 actuates, driving the feeding plate 223 to slide forward (towards the punching and cutting assembly 3) by a preset stroke. Afterward, the pressure drive 211 lifts the pressure block 212, releasing the strip, and then the feeding drive 221 drives the feeding plate 223 back to its original position, preparing for the next feeding cycle.

[0035] Punching and Cutting: After the strip is in place, the third power source at each station first drives the clamping mechanism 32 to firmly press the strip onto the processing platform. Subsequently, the first power source drives the punching punch 311 downward to punch predetermined holes in the strip. After punching is completed, the second power source drives the cutting blade 331 downward to cooperate with the anvil 332 to cut the adhesive film on the punched EVA strip 7, and the cut adhesive film forms a complete independent gasket.

[0036] Material handling: The fourth power source of clamping assembly 4 drives the upper pressure plate 42 to press down, fixing the strip containing the individual pads. Then, the fifth power source of material handling assembly 5 drives the suction nozzle 52 to descend, opening a vacuum to adsorb the individual pads. The fifth power source drives the suction nozzle 52 to rise and remove the individual pads, which is beneficial for subsequent transfer of the individual pads.
