Description

Technical Field

[0001] This utility model relates to the field of photovoltaic production technology, and in particular to a sealing tape anti-pressing structure. Background Technology

[0002] With the depletion of traditional energy sources and increased human awareness of environmental issues, solar power generation, as a clean energy source, has seen tremendous development in order to achieve sustainable energy and environmental development. Crystalline silicon solar photovoltaic modules are further divided into conventional modules and double-glass modules based on the backside material. During the production of double-glass modules, the size of the encapsulation material must be greater than or equal to the size of the glass. Therefore, a lot of adhesive particles will remain around the perimeter of the module. If special tape is used to seal the perimeter of the module, a ring of adhesive edge (called a C-edge) will remain around the perimeter after the module is formed. This not only improves the appearance but also increases the lifespan of the module.

[0003] When sealing transparent substrates such as glass with existing edge banding machines, the tape is easily pressed into the glass surface due to sharp edges or positional errors of the substrate, resulting in rework. The traditional solution is to manually pre-lift the tape, which is inefficient and inconsistent. Utility Model Content

[0004] To address the aforementioned technical problems, an externally mounted, quick-release elastic tape-lifting device is provided, which can automatically lift the tape before it enters the pressure roller, thus preventing it from being pressed into the substrate.

[0005] To achieve the above objectives, this utility model discloses an anti-pressing structure for edge sealing tape, including a base installed on the side plate of an edge sealing machine. The base is detachably connected to the side plate. An installation block hinged to the bottom of the base is installed above the base at a fixed position. An elastic tongue is installed on the installation block. The end of the elastic tongue away from the installation block is bent upward to form a pre-lift angle. The elastic tongue includes a fixed section connected to the installation block and a first step and a second step. A dovetail groove is provided on the installation block. A limiting block that adjusts the vertical height by knurling bolts is provided in the dovetail groove.

[0006] Furthermore, the base is an L-shaped aluminum profile structure, which is formed by welding and fixing two vertically arranged aluminum profiles. At least two permanent magnets are fixed inside the vertically arranged aluminum profiles and are magnetically attracted and fixed to the iron side plate located at the inlet end of the photovoltaic module.

[0007] Furthermore, the elastic tongue is made of integral spring steel and is formed by stamping into two-stage bending. The fixed section is kept horizontal and fixed to the surface of the mounting block by bolts. The angle between the first step and the fixed section is 10° to 15°, and the angle between the second step and the first step is 5° to 10°.

[0008] Furthermore, the end of the second step away from the first step is rounded, and anti-sticking holes are provided on the surface of the second step.

[0009] Furthermore, the limiting block is positioned in the dovetail groove by knurled bolts, and a baffle is provided on the side of the dovetail groove to limit the horizontal position of the limiting block. The shape of the limiting block matches the dovetail groove.

[0010] Furthermore, the surface of the limiting block is provided with scale markings, and the height of the limiting block is greater than the depth of the dovetail groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses an edge sealing tape anti-pressing structure. When the leading edge of the tape passes the elastic flap, the front end of the flap pushes the tape upward under the action of the spring force to form an upward angle. When the glass substrate continues to advance, the tape is already above the upper surface of the glass. The subsequent pressure roller only presses the tape towards the side of the glass, and will not press it under the glass, thus preventing the tape from being pressed under by the glass substrate. The device is installed externally as a whole, without the need to modify the original structure. It can be quickly disassembled and assembled, significantly reducing debugging time and improving the edge sealing yield. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, the base 1 and the side plate 10 are detachably connected. A mounting block 2 is installed above the base 1 at a fixed position and is hinged to the bottom of the base 1. An elastic tongue 3 is installed on the mounting block 2. The end of the elastic tongue 3 away from the mounting block 2 is bent upward to form a pre-lift angle. The elastic tongue 3 includes a fixed section 31 connected to the mounting block 2 and a first step 32 and a second step 33. A dovetail groove 21 is provided on the mounting block 2. A limiting block 5 is provided in the dovetail groove 21, which is adjusted in vertical height by a knurled bolt 6. When the leading edge of the tape passes the elastic tongue, the front end of the tongue pushes the tape upward under the action of the spring force to form an upward angle. When the glass substrate continues to advance, the tape is already above the upper surface of the glass. The subsequent pressure roller only presses the tape towards the side of the glass and will not press it under the glass, preventing the tape from being pressed under the glass substrate. The device is installed externally as a whole, without the need to modify the original structure. It can be quickly disassembled and assembled, significantly reducing debugging time and improving the edge sealing yield.

[0021] The base 1 is an L-shaped aluminum profile structure, which is formed by welding and fixing two vertically arranged aluminum profiles. At least two permanent magnets 4 are fixed inside the vertically arranged aluminum profiles and are fixed to the iron side plate 10 at the inlet end of the photovoltaic module by magnetic attraction. At the same time, the aluminum profile surface has reserved slots for auxiliary screws to strengthen the fixation under certain circumstances.

[0022] The elastic tongue 3 is made of 65Mn integral spring steel and is formed by stamping into two-stage bending. The fixed section 31 is kept horizontal and fixed to the surface of the mounting block 2 by bolts. As a preferred embodiment of this application, the angle between the first step 32 and the fixed section 31 is 12°, and the angle between the second step 33 and the first step 32 is 8°.

[0023] The end of the second step 33 away from the first step 32 is rounded to prevent scratching the tape. The surface of the second step 33 is provided with anti-sticking holes 331 to reduce the contact surface of the tape back adhesive.

[0024] The limiting block 5 is positioned in the dovetail groove 21 by the knurled bolt 6. A baffle 22 is provided on the side of the dovetail groove 21 to limit the horizontal position of the limiting block 5. The shape of the limiting block 5 matches the dovetail groove 21 to prevent the limiting block from deviating from the dovetail groove. A polytetrafluoroethylene sheet is twisted on the top of the limiting block to reduce friction with the elastic tongue.

[0025] The surface of the limiting block 5 is marked with scale markings. The height of the limiting block 5 is greater than the depth of the dovetail groove 21. The position of the limiting block is adjusted according to the photovoltaic modules of different thicknesses, and the lifting height of the elastic tongue is further adjusted. The scale markings record the corresponding positions of different thicknesses, which makes it convenient to directly adjust to the specified position in subsequent production.

[0026] The working principle of this embodiment is as follows: The base is attached to the side plate of the edge banding machine by a permanent magnet. In front of the center line of the pressure roller, the elastic tongue is fixed to the mounting block with screws. The limiting block is inserted into the dovetail groove from below, so that the top of the limiting block contacts the lower surface of the first step. The knurled bolt is rotated so that the scale of the limiting block is aligned with the predetermined reading. At this time, the second step reaches the specified lifting amount. When the leading edge of the tape passes the elastic tongue, the second step at the front end of the tongue pushes the tape upward under the action of the spring force to form an upward angle. When the glass substrate continues to move forward, the tape is already above the upper surface of the glass. The subsequent pressure roller only presses the tape towards the side of the glass, and does not press it under the glass.

[0027] Several points need to be clarified: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships, and the relative positional relationships may change when the absolute position of the described objects changes. Second, in this document, relational terms such as "first" and "second" are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.
