Description

Technical field

[0001] The utility model belongs to the technical field of photovoltaic component production, in particular to an EVA film conveying and positioning mechanism. [Background Technology]

[0002] During the production process of photovoltaic modules, butyl glue needs to be applied around the glass of the photovoltaic modules, and then EVA film is laid. Therefore, the cutting accuracy of the EVA film is required to be high. Therefore, after rough cutting, the EVA film needs to be fine-cut. In order to ensure the accuracy of fine cutting, the precise positioning of the EVA film on the fine cutting machine becomes very critical.

[0003] The EVA film is easy to remove and cannot be easily removed by the suction cup suction machine, so the EVA film is easily removed and cannot be easily removed by the suction cup suction machine.

[0004] In the prior art, for example, Chinese patent authorization announcement No. CN209009648U discloses a highly wear-resistant coated glass clamping device, which is provided with a suction cup for sucking up the glass and a clamping plate for clamping the glass. The device is mainly used to solve the problem of damage and scratches on the glass surface caused by long-term adsorption on the suction cup. The suction cup first absorbs the glass, and then the clamping plate clamps the glass and transports it to the next workstation. For the transportation of EVA film, the above solution can be used as a reference to solve the problem of bulging by using a clamping claw to clamp and transport. However, due to the large size and high flexibility of EVA film, the problem of EVA film deviation cannot be solved.

[0005] Therefore, it is necessary to provide an EVA film transport and positioning mechanism to solve the above technical problems. [Utility Model Content]

[0006] The main purpose of the utility model is to provide an EVA film conveying and positioning mechanism, which solves the bulging problem of the EVA film during the adsorption and conveying process and can also prevent the EVA film from sliding and deflecting during the processing and transportation process.

[0007] The utility model achieves the above-mentioned object through the following technical solutions: an EVA film conveying and positioning mechanism, which includes a conveying frame, a plurality of suction cups arranged on the conveying frame and adsorbing the EVA film, a clamping module arranged on the conveying frame and clamping two opposite long sides of the EVA film, and a hot spot module arranged on the conveying frame and performing hot spot heating on a local position on the short side of the EVA film so that the EVA film is positioned on the component glass;

[0008] The clamping module includes a first cylinder, a first support plate driven by the first cylinder to move in the front-rear direction, a lower clamping plate assembly arranged on the first support plate, and an upper clamping plate assembly arranged relatively above the lower clamping plate assembly;

[0009] The spot ironing module includes a second cylinder, a second support plate driven by the second cylinder to move up and down, and a spot ironing head arranged on the second support plate.

[0010] Preferably, four clamping modules are provided, and every two clamping modules form a group and are provided on two opposite long sides of the EVA film.

[0011] Preferably, there are two hot stamping modules, and the two hot stamping modules are arranged on two opposite short sides of the EVA film.

[0012] Furthermore, the lower clamping plate assembly includes a third cylinder arranged on the first support plate and a lower clamping plate driven by the third cylinder to move up and down.

[0013] Furthermore, the upper clamping plate assembly includes a third support plate arranged on the third cylinder, a fourth cylinder arranged on the third support plate, and an upper clamping plate driven by the fourth cylinder to move up and down.

[0014] Furthermore, the upper clamping plate is arranged parallel to and directly above the lower clamping plate.

[0015] Compared with the prior art, the beneficial effect of the EVA film conveying and positioning mechanism of the utility model is that the provided clamping module can not only assist in clamping and conveying the EVA film, but also when the suction cup breaks the vacuum to loosen the EVA film, due to the gravity of the EVA film, the middle of the EVA film hangs down, and the conveying frame continues to move downward. The clamping module clamps the EVA film and spreads it from the middle to both sides, which can completely discharge the gas between the EVA film and the positioning platform. When the clamping module is released, the EVA film is spread out flat and positioned on the positioning platform, which can avoid the problem of bulging when the EVA film is positioned on the positioning platform; and when the EVA film is spread out flat and positioned on the positioning platform, the provided hot spot module melts the position to be hot spot on the short side of the EVA film, and the molten EVA film is stuck to the component glass. The EVA film is positioned well, which can prevent the EVA film from sliding and offsetting during processing and transportation.

[0025] Please refer to Figures 1-4This embodiment is an EVA film conveying and positioning mechanism. The EVA film conveying and positioning mechanism 100 includes a conveying frame 1, a plurality of suction cups 2 arranged on the conveying frame 1 and adsorbing the EVA film, a clamping module 3 provided on the conveying frame 1 and clamping two opposite long sides of the EVA film, and a hot stamping module 4 provided on the conveying frame 1 and performing hot stamping on a local position on the short side of the EVA film so that the EVA film is positioned on the component glass.

[0026] The transport frame 1 is driven by an XZ axis driving module (not shown) to move along the XZ direction, and transports the EVA film from the rough cutting machine (not shown) to the fine cutting machine (not shown).

[0027] In this embodiment, since the EVA film is rectangular, four clamping modules 3 are provided, with each pair of clamping modules 3 arranged on two opposing long sides of the EVA film. Therefore, two clamping modules 3 are provided on each long side of the EVA film. Four clamping modules 3 are located on two opposing long sides of the EVA film and near the four corners of the film, ensuring stable clamping of the EVA film. In other embodiments, the number of clamping modules 3 may be increased to further improve clamping stability. The number of clamping modules 3 is not limited herein.

[0028] The clamping module 3 includes a first support base 31 arranged on the transport frame 1, a first cylinder 32 arranged on the first support base 31, a first support plate 33 driven by the first cylinder 32 to move along the front and rear directions, a lower clamping plate assembly arranged on the first support plate 33, and an upper clamping plate assembly relatively arranged above the lower clamping plate assembly.

[0029] The lower clamping plate assembly includes a third cylinder 34 provided on the first support plate 33 and a lower clamping plate 35 driven by the third cylinder 34 to move up and down.

[0030] The upper clamping plate assembly includes a third support plate 36 arranged on the third cylinder 34, a fourth cylinder 37 arranged on the third support plate 36, and an upper clamping plate 38 driven by the fourth cylinder 37 to move up and down. The upper clamping plate 38 is arranged parallel to and directly above the lower clamping plate 35.

[0031] The third cylinder 34 drives the lower clamping plate 35 to move upward, and at the same time, the fourth cylinder 37 drives the upper clamping plate 38 to move downward. At this time, the upper clamping plate 38 and the lower clamping plate 35 approach each other and work together to clamp the EVA film; the third cylinder 34 drives the lower clamping plate 35 to move downward, and at the same time, the fourth cylinder 37 drives the upper clamping plate 38 to move upward. At this time, the upper clamping plate 38 and the lower clamping plate 35 move away from each other, loosening the EVA film and positioning the EVA film on the precision cutting machine.

[0032] There are two spot hot stamping modules 4, and the two spot hot stamping modules 4 are arranged on the two opposite short sides of the EVA film. After the four clamping modules 3 clamp the EVA film and place it on the precision cutting machine, the left and right spot hot stamping modules 4 melt the local position of the EVA film, and the melted EVA film is pasted to the component glass, thereby positioning the EVA film, which can prevent the EVA film from sliding and offsetting during processing and transportation, and facilitate subsequent precision cutting and punching operations.

[0033] The spot ironing module 4 includes a second support base 41 arranged on the transport frame 1, a second cylinder 42 arranged on the second support base 41, a second support plate 43 driven by the second cylinder 42 to move up and down, and a spot ironing head 44 arranged on the second support plate 43.

[0034] When the EVA film conveying and positioning mechanism 100 provided by the present invention is applied, the XZ-axis driving module (not shown in the figure) drives the conveying frame 1 to move to the rough cutting machine (not shown in the figure) and drives the conveying frame 1 to descend. Several suction cups 2 simultaneously adsorb the EVA film. The XZ-axis driving module (not shown in the figure) drives the conveying frame 1 to move upward. In the process of the conveying frame 1 moving upward, the first cylinder 32 of the clamping module 3 drives the first support plate 33 to drive the lower splint assembly and the upper splint assembly to move close to the long side of the EVA film, and make the EVA film located between the lower splint 35 and the upper splint 38. The third cylinder 34 drives the lower splint 35 toward The upper clamping plate 38 and the lower clamping plate 35 move upward, and the fourth cylinder 37 drives the upper clamping plate 38 to move downward. The upper clamping plate 38 and the lower clamping plate 35 approach each other and work together to clamp the EVA film. At this time, several suction cups 2 adsorb the EVA film, and at the same time, four clamping modules 3 clamp the two relatively long sides of the EVA film. The XZ axis driving module (not shown in the figure) drives the transport frame 1 to move horizontally to the top of the fine cutting machine (not shown in the figure). The XZ axis driving module (not shown in the figure) drives the transport frame 1 to move downward for a distance. The suction cup 2 breaks the vacuum to release the EVA film. Only the four clamping modules 3 clamp the two relatively long sides of the EVA film. After the suction cup 2 is released, due to the EVA glue The gravity of the film causes the middle of the EVA film to hang down, and the XZ-axis driving module (not shown) drives the transport frame 1 to move downward until the middle of the EVA film contacts the positioning platform of the precision cutting machine (not shown). The third cylinder 34 drives the lower clamping plate 35 to move downward, and the fourth cylinder 37 drives the upper clamping plate 38 to move upward. The upper clamping plate 38 and the lower clamping plate 35 move away from each other, loosening the EVA film. The first cylinder 32 drives the first supporting plate 33 to make the lower clamping plate assembly and the upper clamping plate assembly move away from the long side of the EVA film. At this time, the EVA film spreads out from the middle to both sides, and completely discharges the gas between the EVA film and the positioning platform, clamping When the module 3 is released, the EVA film is spread out flatly and positioned on the positioning platform of the precision cutting machine (not shown in the figure), which can prevent the EVA film from bulging when it is positioned on the positioning platform. The EVA film is spread out flatly on the positioning platform, which can improve the accuracy of cutting and punching; after the EVA film is spread out flatly on the positioning platform, the second cylinder 42 drives the second support plate 43 to drive the hot stamping head 44 to descend, and the hot stamping head 44 melts the position to be hot stamped on the short side of the EVA film, and the molten EVA film is adhered to the component glass, thereby positioning the EVA film, which can prevent the EVA film from sliding and offsetting during processing and transportation.

[0035] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
