Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module technology, specifically relating to a trimming mechanism for excess adhesive in laminated glass of photovoltaic modules. Background Technology

[0002] With increasing calls for environmental protection, my country has begun shifting from traditional power generation models to solar photovoltaic (PV) power generation in order to increase the proportion of new and clean energy power generation. PV modules are a crucial component in realizing solar PV power generation, typically composed of core components such as glass, EVA film, solar cells, and a backsheet. Glass primarily protects the solar cells, possessing high light transmittance and mechanical strength, capable of withstanding significant wind and snow pressure, ensuring the stability and durability of the module in harsh environments. During the glass lamination process, excess adhesive may overflow, requiring edge trimming around the glass. Current edge trimming methods typically employ manual, hand-held single-blade trimming mechanisms on the sides of the glass module, which is inefficient and can result in inconsistent trimming quality due to varying operator skill levels. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a trimming mechanism for excess adhesive in laminated glass of photovoltaic modules, which can quickly and effectively remove excess adhesive with high stability.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A trimming mechanism for overflowing adhesive in laminated glass of photovoltaic modules includes a trimming assembly and a clamping assembly for holding the glass located below the trimming assembly. The trimming assembly includes a trimming cylinder and a blade assembly connected to the trimming cylinder. The blade assembly consists of three blades arranged in parallel, and a front-to-back displacement difference is provided between the three blades and the trimming cylinder.

[0006] Preferably, the blade assembly includes a first blade, a second blade, and a third blade arranged side by side from the outside in. The distance between the three blades and the edge-trimming cylinder increases progressively, and the distance between the third blade and the edge-trimming cylinder is greater than the distance between the first blade and the edge-trimming cylinder.

[0007] Preferably, the blade assembly is connected to the cylinder shaft of the edge-trimming cylinder via a blade base.

[0008] Preferably, the clamping assembly includes a clamping cylinder located outside the blade assembly and a clamping pressure roller connected to the clamping cylinder.

[0009] Preferably, there are two clamping cylinders, and the cylinder shafts of the two clamping cylinders are arranged in opposite directions.

[0010] Preferably, the clamping cylinder is connected to the outside of the blade base via a connecting seat.

[0011] Preferably, the clamping pressure roller is positioned at the front of the blade assembly via a connecting rod.

[0012] Preferably, the two clamping cylinders drive the corresponding clamping pressure rollers to reciprocate in the vertical direction.

[0013] Preferably, the edge-trimming mechanism is placed on the transfer line.

[0014] The beneficial effects of this utility model are as follows: This utility model achieves multiple removals of excess glue from the glass edge through parallel progressive blades, and with the help of clamping pressure rollers, the glass can be clamped during the removal of excess glue, keeping the glass edge flat and not prone to tilting, thus making the removal of excess glue more effective.

[0016] Figure 2 : A schematic diagram of the structure of this utility model placed on the transfer line. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1-2 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0018] The edge trimming mechanism 6 for excess adhesive on laminated glass of photovoltaic modules disclosed in this utility model is usually placed on the transfer line 5 and moved on the transfer line 5 by a motor 51 to remove excess EVA adhesive from the glass edge of the photovoltaic module.

[0019] The edge trimming mechanism 6 for overflowing adhesive in laminated glass of photovoltaic modules includes an edge trimming component and a clamping component for clamping glass located below the edge trimming component.

[0020] The edge-trimming assembly includes an edge-trimming cylinder 3 and a blade assembly connected to the edge-trimming cylinder 3. The blade assembly is connected to the cylinder shaft of the edge-trimming cylinder 3 via a blade base 34. The blade assembly consists of three blades arranged side-by-side, configured from the outside in as a first blade 31, a second blade 32, and a third blade 33. The distance between the three blades and the edge-trimming cylinder increases progressively, with the distance between the third blade 33 and the edge-trimming cylinder 3 being greater than the distance between the first blade 31 and the edge-trimming cylinder 3. In this invention, "from the outside in" refers to the order in which the glass adhesive comes into contact with it; that is, when trimming the adhesive, the first blade 31 trims the adhesive first, acting as the outside, followed by the second and third blades. The farther away from the edge-trimming cylinder, the closer to the glass adhesive. Typically, the total increment between the three blades does not exceed 2.5 mm.

[0021] The clamping assembly includes a clamping cylinder located outside the blade assembly and a clamping pressure roller connected to the clamping cylinder. The clamping cylinder is connected to the outside of the blade base 34 via a connector 22, and the clamping pressure roller is located at the front of the blade assembly via a connecting rod.

[0022] In this embodiment, two clamping cylinders are provided, including a first clamping cylinder 1 and a second clamping cylinder 2. The first clamping cylinder 1 is connected to a first clamping pressure roller 11, and the second clamping cylinder 2 is connected to a second clamping pressure roller 21. The cylinder axis of the first clamping cylinder is arranged upward, and the cylinder axis of the second clamping cylinder is arranged downward. The two clamping cylinders respectively drive the corresponding clamping pressure rollers to perform reciprocating motion in the vertical direction. The two clamping pressure rollers work together to press the upper and lower surfaces of the glass.

[0023] During edge trimming, the clamping cylinder drives the clamping pressure roller to press the glass firmly. As the trimming mechanism moves, the first blade trims the excess adhesive, followed by the second and third blades arranged parallel to it. Because of the displacement difference between the three blades, excess adhesive left by the previous blade can be further removed. This design is also intended to address the issue that the glass assembly may be tilted when entering the adhesive removal device during lamination. Using only a single blade to remove excess adhesive would likely result in a high probability of residual adhesive. Therefore, by using three blades in combination and controlling the displacement between them, the occurrence of residual adhesive can be reduced.

[0024] The edge-trimming mechanism shown in the figure has two symmetrically arranged on the base 4 to meet the needs of trimming different edges and directions of the glass assembly in practical applications.
