[0002] As a representative of the new energy field, the application scope of the photovoltaic industry is constantly expanding. Butyl tape has become one of the important auxiliary materials in the photovoltaic industry due to its excellent waterproof, sealing, adhesion, weather resistance and chemical corrosion resistance. In the production process of photovoltaic modules, butyl tape is often used to stick to the surface of the module to protect the edge of the photovoltaic module and prevent the internal module from being damaged by the erosion of the external environment. At the same time, butyl tape has good sealing performance, so it can also prevent water, oxygen and other pollutants from entering the module, thereby reducing the service life of the photovoltaic module. The existing tape application is usually done manually. Due to the low efficiency of manual application, tape applying machines have emerged. However, the existing tape applying machines are only suitable for conventional tapes, while the tape body of butyl tape is combined with release paper, and the release paper needs to be recovered during application. Therefore, the existing tape applying machines cannot be well applied to the application of butyl tape. At the same time, during the application of butyl tape, it is necessary to ensure that the application position of the photovoltaic module and the tape is accurate to avoid missing places caused by errors that affect the sealing of the photovoltaic module. Therefore, the tape winding amount needs to be strictly controlled during tape application. How to better control the tape winding is also a technical problem that needs to be solved at present.

[0023] The present invention discloses a butyl tape applying mechanism and equipment thereof, which is combined with Figure 1-Figure 7 As shown, the structure of the butyl tape applying mechanism in the present invention is described below.

[0024] Combination Figure 1As shown, the butyl tape applying mechanism includes a back plate 1, on which a loading tray assembly 2, a straightening and cutting assembly 3, a pressure roller assembly 4, a release paper recovery assembly 6, and a release paper brake assembly are arranged.

[0025] The loading tray assembly 2 is arranged at the upper end side of the back plate 1, and is used to place the butyl tape reel 12 for unwinding the tape. The straightening and cutting assembly 3 and the release paper recovery assembly 6 are respectively arranged on both sides below the loading tray assembly 2. The straightening and cutting assembly 3 includes a straightening assembly for straightening the butyl tape and a cutting assembly for cutting the butyl tape arranged below the straightening assembly. The pressure roller assembly 4 is placed at the lower end of the back plate 1 between the straightening and cutting assembly 3 and the release paper recovery assembly 6. The release paper brake assembly is placed below the release paper recovery assembly 6. The butyl tape starts from the loading tray assembly 2, is guided by the guide wheel 23, and then enters the straightening assembly for straightening, and then reaches the pressure roller assembly through the cutting assembly, and is applied by passing around the bottom of the pressure roller assembly. The release paper on the butyl tape is guided again by the guide wheel and enters the release paper brake assembly, and is finally wound around the release paper recovery assembly 6. The release paper recovery assembly 6 is driven by the motor on the back side of the back plate 1 to realize rotation and material collection, thereby driving the loading tray assembly 2 to rotate and discharge the material.

[0026] Combination Figure 2-Figure 4 As shown, the loading tray assembly 2 includes a fixed shaft 27 vertically arranged on the back plate 1, and a tape reel support assembly is sleeved on the fixed shaft 27.

[0027] The tape reel support assembly includes a coaxial tape reel front baffle 22, a tape reel rear baffle 21, and a tape reel support sleeve assembly placed between the tape reel front baffle 22 and the tape reel rear baffle 21, and the three are connected by bolts axially penetrating. The tape reel support sleeve assembly includes a tape reel support sleeve 223 placed on a fixed shaft 27, and the circumferential surface of the tape reel support sleeve 223 is evenly embedded with tape reel support blocks 24 through springs 241, and the springs 241 support the tape reel support blocks 24 to achieve elastic floating on the surface of the tape reel support sleeve 223. When there is no external force, the tape reel support blocks 24 will float on the outer surface of the tape reel support sleeve 223 under the action of the spring. The floating tape reel support blocks 24 can make different tape reels tightly attached to the tape reel support assembly. And because the tape reel support assembly is a driven part, the floating design can also play an auxiliary buffering role when the tape is rotated, making the rotation of the tape reel more stable.

[0028] In order to reduce the change in the amount of tape caused by the inertia during the rotation of the tape reel, the outer side surfaces of the tape reel front baffle 22 and the tape reel rear baffle 21 are both provided with damping friction components, and the outer side of the damping friction component placed at the tape reel front baffle is compressed by a compression spring 25. For a better understanding, the present invention is described by taking the inside of the tape reel front baffle 22 as an example in combination with the diagram. The damping friction component includes a metal friction plate 28 and a nylon friction plate 26 covering the metal friction plate 28, and one end of the compression spring 25 abuts against the nylon friction plate 26 to compress it.

[0029] The inner circle gap of the front baffle plate 22 of the tape reel is evenly provided with slots 221, and the metal friction plate 28 is provided with protrusions for being stuck in the slots 221, that is, the metal friction plate covers the surface 222 of the front baffle plate 22 of the tape reel, and is fixedly connected with the front baffle plate 22 of the tape reel by being stuck in the slots 221. When the tape reel support assembly rotates, the metal friction plate 28 also rotates. Since the rotation amount needs to be strictly controlled when the tape is applied, in order to control the rotation, damping will be generated between the nylon friction plate 26 and the metal friction plate 28, which will limit the rotation of the metal friction plate to a certain extent. The implementation principle is that the surface of the fixed shaft 27 is evenly distributed with four axial sections, so that the cross section of the fixed shaft 27 is not a conventional circular structure, but a quadrilateral structure with arc-shaped ends. The center of the nylon friction sheet 26 is provided with a quadrilateral center hole for being sleeved on the fixed shaft 27. The nylon friction sheet 26 is sleeved on the fixed shaft 27 through the quadrilateral center hole, and one side surface of the nylon friction sheet 26 is pressed against the metal friction sheet 28 through the pressing spring 25. That is, when the metal friction sheet 28 rotates with the front baffle plate 22 of the tape reel, the nylon friction sheet 26 does not rotate, thereby generating damping between the nylon friction sheet 26 and the metal friction sheet 28.

[0030] Since the tape reel support assembly may be eccentric with the metal friction plate 28 when rotating, resulting in an error in the amount of tape unloading, in order to minimize the error as much as possible, a silicone layer is further provided between the metal friction plate 28 and the surface 222 of the tape reel front baffle 22. The silicone layer can form a more stable relative relationship between the metal friction plate 28 and the surface 222.

[0031] Similarly, the setting form of the damping friction component in the rear baffle 21 of the tape reel is the same as that of the front baffle 22 of the tape reel, and will not be repeated here. Further, at the winding end, the release paper recovery component includes a material tray connected to the motor on the other side of the back plate 1. The above forms are adopted in the material tray at the same time, that is, both ends can be controlled simultaneously, so that the tape application amount and application position can be accurately controlled to the maximum extent.

[0032] Combination Figure 5As shown, in the present invention, the correction component includes a correction base plate 31, and a threading groove 32 for threading the tape is provided on the correction base plate 31. A correction cylinder 33 is provided on the threading groove side of the correction base plate 31. The correction cylinder 33 is connected to a pressing block 34, and the correction cylinder 33 drives the pressing block 34 to reciprocate in the direction of the threading groove. Figure 6 As shown, the cutting assembly includes a cutting cylinder 35 disposed below the alignment cylinder 33 and a cutter 36 connected to the cylinder shaft of the cutting cylinder 35. When the cutting cylinder 35 works, it drives the cutter 36 to reciprocate in the direction of the penetration groove to realize the cutting action.

[0033] The pressure roller assembly includes a pressure roller 43 and a lifting assembly 42 disposed above the pressure roller 43. The lifting assembly 42 in the mechanism of the present invention is a lifting spring. When applying the tape, the pressure roller 43 is pressed downward against the product to apply the tape, and the lifting spring will be compressed. Due to the material properties of the butyl tape, a hot air gun assembly 41 is disposed on one side of the pressure roller assembly 4 to make the butyl tape more firmly applied.

[0034] Combination Figure 7 As shown, the release paper brake assembly is used to position the release paper when the tape is cut, that is, in order to avoid the application part from being in a tensioned state when the tape is cut, the two ends of the application need to be pressed and positioned. The release paper brake assembly includes a brake bracket 52 arranged below the release paper recovery assembly, and a brake cylinder 51 is arranged in the brake bracket 52. Specifically, the brake bracket 52 is in a door-shaped opening shape, and its opening is placed outward on the back plate 1. One end of the brake bracket is provided with a notch 521 for passing the release paper along the opening direction of the brake bracket. The notch 521 is opened so that a brake pad is formed on the inner side of the notch. The brake cylinder 51 is vertically connected to the other end of the brake bracket, and the cylinder shaft of the brake cylinder 51 is arranged opposite to the notch side. When the brake cylinder 51 is working, the cylinder shaft squeezes the brake pad at the notch of the brake bracket. If there is release paper in the notch, it can play a role in pressing the release paper. Of course, the brake bracket can also be in other forms, and no specific restrictions are made here.

[0035] The mechanism of the present invention drives the material tray at the material discharging end to rotate when applying the tape, and the application of the tape can be completed with the help of the pressure roller assembly. When a section of the tape is applied, the motor stops rotating, and at this time, the cylinders at the release paper brake assembly and the return assembly will act simultaneously to first clamp the tape and the release paper to position, keep the tension state of the applied section of the tape at this time, and then the cutting cylinder acts to cut the tape.

[0036] Based on the above-mentioned butyl tape applying mechanism, the overall movement of the butyl tape applying mechanism in the X direction, the Y direction and the Z direction can be realized by arranging a transfer assembly on the other side of the back plate.
