[0021] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.
[0022] Please refer to Figure 1 , a kind of automatic loading and cutting equipment of photovoltaic module adhesive film provided in the embodiment is shown, including loading device 1, length monitoring device 2, adhesive film splicing device 3, conveying device 4 and laser cutting device 5. Among them, loading device 1, length monitoring device 2, adhesive film splicing device 3 and laser cutting device 5 are arranged in sequence along a direction, and conveying device 4 is located directly below length monitoring device 2, adhesive film splicing device 3 and laser cutting device 5. The adhesive film splicing device 3 is used to melt the butt joint of the two adhesive films aligned by the loading device 1, so as to realize the splicing of the two adhesive films. The spliced adhesive film is conveyed to the laser cutting device 5 by the conveying device 4. The laser cutting device 5 cuts the adhesive film according to the preset size to obtain the target adhesive film.
[0023] Please refer to Figure 2 , loading device 1 includes fixed support 11, rotating motor 12, loading roller support 13, loading platform 14, stretching manipulator 15 and material changing manipulator (not shown in the figure). Among them, the loading roller support 13 is a cylindrical frame, and the loading roller support 13 is suspended and fixed on the fixed support 11, and the loading roller support 13 is provided with a plurality of support rods 131 distributed in a circumferential direction, and the adhesive film roll is rotatably sleeved on the support rod 131. The stretching manipulator 15 is located on the outer side of the loading roller support 13, and the stretching manipulator 15 is a multi-axis manipulator, and the distal end is provided with two clamping jaws. The stretching manipulator 15 can drive the clamping jaws to move and rotate in three-dimensional space, and the two clamping jaws can clamp the end of the adhesive film on the outermost layer of the adhesive film roll, and pull the adhesive film. At this time, the adhesive film drives the entire adhesive film roll to rotate around the support rod 131, and the adhesive film is stretched out of the adhesive film roll by the stretching manipulator 15 and conveyed to the conveying device 4 below the length monitoring device 2 for length measurement by the length monitoring device 2.
[0024] Further, the rotary motor 12 is fixedly connected with the center position of the end of the feeding roller support 13 through the belt pulley transmission assembly 16 and the shaft coupling 17, and the feeding platform 14 and the material changing manipulator are located below the feeding roller support 13. When the material needs to be changed, the rotary motor 12 drives the feeding roller support 13 to rotate, so as to rotate the empty rubber film roll (rubber roller) to the position close to the feeding platform 14, and the material changing manipulator can detach the rubber film roll, and then grab the new rubber film roll stored on the feeding platform 14 and mount the rubber film roll on the support rod 131 close to the feeding platform 14.
[0025] It should be noted that the conveying device 4 can be a driving conveying device with a power source or a driven conveying device without a power source. When the driven conveying device is adopted, the stretching force of the conveying manipulator on the rubber film can be used as the power, so that the rubber film moves forward along the transmission belt of the conveying device 4. In the embodiment, please refer to Figures 3 to 6 , the conveying device 4 is a driven conveying device, which comprises a plurality of horizontally arranged conveying rollers 41, a transmission belt 42 arranged on the periphery of the conveying rollers 41, and a conveying manipulator (not shown in the figure) located at the outer side of the transmission belt 42. The surface of the transmission belt 42 has a certain roughness, and the surface of the rubber film in contact with the transmission belt 42 also has a certain roughness, so that the relative static state of the rubber film and the transmission belt 42 is realized through the friction force. When the conveying roller 41 rotates to drive the transmission belt 42 to move forward, the transmission belt 42 drives the rubber film to move forward together, thereby realizing the conveying of the rubber film.
[0026] The transmission belt 42 is provided with a detection sensor at the outer side close to the positions of the feeding platform 14 and the rubber film splicing device 3, so that whether the rubber film passes through or whether the two rubber film rolls are well butt-jointed when splicing can be judged, thereby facilitating the automatic operation. The cut rubber film is conveyed to the designated position through the transmission belt 42, and the position sensor is arranged at the position. After the position sensor detects the rubber film, a feedback signal is fed back to the material changing manipulator, the material changing manipulator grabs the rubber film and places the rubber film in the center of the conveying belt, and then continues to convey, so as to perform the subsequent process operation.
[0027] Please refer to Figure 3 , the length monitoring device 2 is used for monitoring the used length of the rubber film, and is located between the feeding device 1 and the rubber film splicing device 3.

The hot pressing sliding block 35 drives the hot pressing assembly to move up and down while sliding up and down, so that the silica gel heating plate 34 hot presses the butt joint of the two films, so that the butt joint of the two films is hot melted to realize bonding. When the hot pressing is completed, the linear driving module lifts the silica gel heating plate 34 to release the film. In this embodiment, the specific structure of the linear driving module is not limited. For example, the linear driving module can adopt a combination structure of a motor and a screw pair, or can adopt a power mechanism capable of outputting linear motion such as a pneumatic cylinder or an electric cylinder.

The industrial computer is electrically connected with the translation driving mechanism, and is used for controlling the moving path of the second light emitting lens 52.
[0034] Specifically, the translation driving mechanism comprises an X-direction driving motor 53, an X-direction belt pulley transmission assembly 54, an X-direction translation shaft 55, a Y-direction driving motor 56, a Y-direction belt pulley transmission assembly 57, a Y-direction translation shaft 58 and a laser sliding block 59.

When the X-direction driving motor 53 and the Y-direction driving motor 56 work, the laser sliding block 59 can be driven to move along the X direction or the Y direction, and then the light emitting lens is driven to translate along the preset moving path, so that the adhesive film of a corresponding size is cut off to obtain a target adhesive film.
[0035] In the embodiment, the second laser is a 532nm picosecond laser or a 10.5micron carbon dioxide laser (the laser cutting device 5 can share one laser with the laser welding device). The light emitted by the laser is transmitted to the light emitting lens through the light path. The cutting software on the industrial computer inputs the drawing in advance. By controlling the moving path of the light emitting lens and adjusting the appropriate energy, the adhesive film of a specified size is cut off from the whole, and the size range accuracy is ±20μm.
