DETAILED DESCRIPTION

[0022] To make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of ways other than those specifically described herein, and skilled artisans can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0023] In the process of laying the adhesive film of a photovoltaic assembly, the adhesive film roll needs to be installed on a cutting machine. At present, manual operation is used to complete the winding operation of the adhesive film on the inflatable shaft. The operator first needs to attach one end of the adhesive film to the surface of the inflatable shaft, and then gradually winds the adhesive film on the inflatable shaft. After completing the winding, the inflatable shaft is inflated, and the pressure generated by the gas expansion is used to fix the position of the adhesive film, preventing it from loosening or shifting in subsequent operations. Although a scale is designed on the inflatable shaft, the operator may make errors in reading the scale when winding, resulting in large or small shifts in the winding position of the adhesive film. This inaccuracy in winding position will affect the cutting quality of the adhesive film.

[0024] Please refer to Figure 1, based on the above problems, the application provides a limiting tool 100, which comprises a movable assembly 1 and a limiting assembly 2. The movable assembly 1 is arranged on a winding assembly 200 and can extend and retract along the axial direction of the winding assembly 200. The limiting assembly 2 is connected to the movable end of the movable assembly 1, the movable assembly 1 is used to move the limiting assembly 2 along the axial direction of the winding assembly 200, and the limiting assembly 2 is used to abut against the material roll. The limiting tool 100 is installed on the winding assembly 200 (inflatable shaft), because the movable assembly 1 can extend and retract along the axial direction of the winding assembly 200, by adjusting the movable assembly 1, the limiting assembly 2 connected to the movable end of the movable assembly 1 can be moved along the axial direction. In the process of installing the adhesive film roll, first, according to the required winding position of the adhesive film, the position of the limiting assembly 2 is adjusted in advance through the movable assembly 1, so that the limiting assembly 2 is located at the boundary position of the adhesive film winding. When the adhesive film is wound, the limiting assembly 2 abuts against the material roll, so that the winding range of the adhesive film is limited, and the deviation of the winding position of the adhesive film is effectively prevented. Compared with the method of positioning by relying on the scale of the inflatable shaft and the limited operation precision, the limiting tool 100 can more accurately determine the winding position of the adhesive film, so as to ensure the cutting quality of the adhesive film, avoid the problems of lack of adhesive, bubbles, and cracks of photovoltaic modules in the laminating process caused by the deviation of the winding position of the adhesive film, and greatly improve the stability of the adhesive film laying and the subsequent photovoltaic module production process and the product quality.

[0025] In optional embodiments, the movable assembly 1 and the limiting assembly 2 can be integrally formed. For example, the limiting tool 100 is an integrally formed telescopic sleeve, the telescopic sleeve can extend and retract along the axial direction of the telescopic sleeve, the telescopic sleeve can be sleeved on the winding assembly 200, and one side end of the telescopic sleeve is used to abut against the material roll. In other optional embodiments, the movable assembly 1 and the limiting assembly 2 are separately formed. For example, the movable assembly 1 can be a sliding assembly, a folding assembly, a nested assembly or the like which can change the length of the assembly.

[0026] The application does not limit the arrangement mode of the movable assembly 1 on the winding assembly 200. The movable assembly 1 can be sleeved on the outer periphery of the winding assembly 200 or arranged on one side of the winding assembly 200. For example, when the movable assembly 1 is a sliding assembly or a folding assembly, the movable assembly 1 can be arranged on one side of the winding assembly 200. When the movable assembly 1 is a nested assembly, the movable assembly 1 can be sleeved on the outer periphery of the winding assembly 200.

[0027] Please refer to Figure 2 In some embodiments, the movable assembly 1 comprises a fixed part 11 and a movable part 12 which are connected in a sliding mode, the movable part 12 slides along the axial direction of the winding assembly 200 relative to the fixed part 11, and the movable part 12 is connected with the limiting assembly 2.

[0029] Referring to Figure 2 In other optional embodiments, when the movable assembly 1 is a sliding assembly, in some embodiments, the fixed part 11 includes a sliding rail 111, and the movable part 12 includes a sliding block 121 in sliding connection with the sliding rail 111, the sliding rail 111 extends along the axial direction of the winding assembly 200, and the sliding block 121 is connected with the limiting assembly 2. The linear motion of the sliding rail 111 and the sliding block 121 has higher precision.

[0030] Referring to Figure 2 In some embodiments, the fixed part 11 includes a fixed portion 112 and a limiting portion 113 connected with each other, the fixed portion 112 extends along the axial direction of the winding assembly 200, the fixed portion 112 is in sliding connection with the movable part 12, and the limiting portion 113 abuts against the end of the winding assembly 200 along the axial direction thereof. By arranging the limiting portion 113, the axial position of the fixed part 11 on the winding assembly 200 can be positioned, and the fixed part 11 can be prevented from being deviated.

[0031] Referring to Figure 2 In optional embodiments, the limiting portion 113 includes a first portion 1131 and a second portion 1132 connected by bending. The first portion 1131 is connected with the fixed portion 112, and the second portion 1132 abuts against the end of the winding assembly 200 along the axial direction thereof.

The third portion 1133 is provided with a notch, and the third portion 1133 is used for clamping the winding shaft of the winding assembly 200.

[0034] Referring to Figure 2In some embodiments, the limiting assembly 2 comprises a clamping portion 21 and an abutting portion 22 connected together, the clamping portion 21 is connected to the movable end of the movable assembly 1, and the clamping portion 21 is used to clamp the winding assembly 200, and the abutting portion 22 is used to abut against the winding material when the clamping portion 21 is clamped on the winding assembly 200. The clamping portion 21 is arranged to prevent the limiting assembly 2 from loosening, and to make the installation and position adjustment of the limiting tool 100 more flexible, and only needs to clamp the clamping portion 21 on the specified position of the winding assembly 200.

[0035] In optional embodiments, the clamping portion 21 can be elastically clamped on the winding assembly 200, or can be rigidly clamped on the winding assembly 200. For example, when the clamping portion 21 is rigidly clamped, the clamping portion 21 can be a pneumatic or electric clamp jaw.

[0036] Please refer to Figure 2 In some embodiments, the clamping portion 21 comprises two clamping arms 211 connected to the movable end, and the abutting portion 22 is arranged on the clamping arms 211, and the two clamping arms 211 are used to elastically clamp on the winding assembly 200. The clamping arms 211 are elastically clamped on the winding assembly 200, which can adapt to winding assemblies 200 of different radial sizes, and can also simplify the structure of the clamping portion 21. In addition, the two clamping arms 211 can be clamped on the two side circumferential surfaces of the winding assembly 200, which can increase the clamping area of the clamping portion 21, and further improve the clamping stability.

[0037] In optional embodiments, the clamping arms 211 can be elastic clamping arms, for example, the clamping arms 211 are elastic pieces, and the clamping portion 21 further comprises a clamping handle, and the clamping handle and the elastic pieces form a clamping structure similar to a dovetail clamp. The clamping handle is connected to the elastic pieces, and by pressing the tail handle, the two elastic pieces are away from each other to clamp the winding assembly 200, and by releasing the tail handle, the two elastic pieces are close to each other.

[0038] Please refer to Figure 2 In other optional embodiments, the clamping arms 211 are non-elastic clamping arms, and in some embodiments, the clamping portion 21 further comprises an elastic member 212 connected between the two clamping arms 211. The elastic member 212 can facilitate clamping, and can also stabilize the distribution of clamping force, so that the clamping force of the two clamping arms 211 remains balanced.

[0039] Please refer to Figure 2In optional embodiments, the clamping portion 21 further comprises a support 213, which is connected to the clamping arm 211 and / or the elastic member 212 at one end along the length of the support 213, and connected to the movable member 12 in the movable assembly 1 at the other end of the support 213. The support 213 can be connected to the clamping arm 211, or connected to the outside of the elastic member 212, or the support 213 can be connected to both the clamping arm 211 and the elastic member 212. The addition of the support 213 can improve the connection stability between the clamping portion 21 and the movable member 12, and further improve the connection stability between the limiting assembly 2 and the movable assembly 1.

[0040] Referring to Figure 2 In some embodiments, the clamping surface of the clamping portion 21 is provided with an anti-skid portion 214, which is used to abut against the winding assembly 200. The provision of the anti-skid portion 214 can increase the friction between the clamping portion 21 and the winding assembly 200, and further prevent the clamping position of the clamping portion 21 from shifting.

[0041] Referring to Figure 2 In optional embodiments, the anti-skid portion 214 is provided on the clamping arm 211 of the clamping portion 21.

[0042] Referring to Figure 2 In optional embodiments, the anti-skid portion 214 can be an anti-skid strip, an anti-skid tooth, or the like. When the anti-skid portion 214 is an anti-skid tooth, the anti-skid teeth can be continuously provided along the clamping surface.

[0043] Referring to Figure 2 In some embodiments, the abutting portion 22 comprises two abutting members 221, which are respectively provided on the two clamping arms 211. Since the two clamping arms 211 are clamped on both sides of the winding assembly 200, the provision of the two abutting members 221 can increase the abutting area of the abutting portion 22, and thus can limit the material in a larger area range.

[0044] In optional embodiments, the abutting member 221 can be provided on the top of the clamping arm 211 along the radial direction of the winding assembly 200. The side surface of the abutting member 221 is flush with the side surface of the clamping arm 211. At this time, the material can simultaneously abut against the clamping arm 211 and the abutting member 221.

[0045] Referring to Figure 2 In other optional embodiments, in some embodiments, the abutting member 221 is arranged on the side of the corresponding clamping arm 211 away from the clamping portion 21, and extends away from the clamping arm 211 along the radial direction of the winding assembly 200. At this time, the material only abuts against the abutting member 221. Arranging the abutting member 221 on the side of the clamping arm 211 can increase the connection area between the abutting member 221 and the clamping arm 211, and further increase the connection stability between the abutting member 221 and the clamping arm 211.

[0046] In an optional embodiment, the abutting member 221 can be an abutting plate or an abutting block or the like structure. The shape of the abutting member 221 can be a fan shape or a square shape or the like.

[0047] In summary, the limiting tool 100 provided by the embodiment of the application can fix the movable assembly 1 on the winding assembly 200 through the limiting part 113 on the fixing member 11, pull the movable member 12 to move the movable member 12 along the axial direction of the winding assembly 200 relative to the fixing member 11, and then drive the abutting part 22 of the limiting assembly 2 to move to a specified position, so that the clamping part 21 is clamped on the winding assembly 200, thereby completing the installation of the limiting tool 100, and then the limiting tool 100 can abut against the roll material, so that the roll material is wound at the specified position, the deviation of the roll material is reduced, the cutting quality is improved, and then the product quality of the photovoltaic assembly is improved.
