Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel production technology, specifically relating to a caulking mechanism for photovoltaic panel assembly, and more particularly to a caulking mechanism for photovoltaic panel production. Background Technology

[0002] During the construction of a photovoltaic power station, after the photovoltaic modules are fixed on the bracket rails, an installation gap will be formed between the module frame and the rails. After the installation is completed, it is an essential and critical process to reliably seal this gap.

[0003] Currently, in order to achieve effective sealing, the industry generally uses manual or automated equipment to inject sealants such as silicone and polyurethane to fill the gaps. The long-term effectiveness of the sealant strictly depends on one core premise: that is, it must form a firm, continuous and defect-free bonding interface with the metal substrate (support and component frame). Any poor bonding will lead to seal failure and form a potential leakage channel.

[0004] In related technologies, to improve the adhesion between the colloid and the substrate, the surface is pretreated before application. This involves integrating a high-pressure air nozzle into the front of the colloid gun nozzle to clean the gaps to be filled using air purging. However, high-pressure air purging can only remove loose contaminants such as dust and debris within the gaps. It is almost impossible to remove more adhesive contaminants (such as oil stains, sticky dirt, oxide layers, tiny cured adhesive dots, and protruding weld slag or burrs) that adhere to the surface of the bracket guide rail during transportation, storage, and installation. These stubborn deposits form a physical isolation layer, significantly reducing the effective bonding strength and durability of the sealant.

[0005] Therefore, how to solve the problem of stubborn residues on the substrate surface before applying adhesive is a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0007] This disclosure provides at least one caulking mechanism for photovoltaic panel production to solve the technical problem of stubborn residues on the substrate surface before adhesive application.

[0008] In a first aspect, embodiments of this disclosure provide a caulking mechanism for photovoltaic panel production, comprising: a machine body; a glue applicator disposed within the machine body with a glue applicator head extending outside the machine body; and a cleaning unit disposed on the machine body. The cleaning unit includes: an air pipe disposed on the glue applicator or the machine body; and a cleaning head disposed at the tail end of the air pipe and connected to the air pipe. The cleaning head has a groove to form a tongue at its tail end, the tongue being adapted to extend into the edge seam. At least one airflow outlet is provided on the inclined surface of the groove corresponding to the edge seam.

[0009] In one alternative embodiment, the end of the tongue is flattened, and its thickness is less than or equal to the width of the seam.

[0010] In one optional embodiment, the upper top surface and lower bottom surface of the tongue are provided with a plurality of toothed grinding strips.

[0011] In one alternative implementation, the opening width of the groove converges along its depth.

[0012] In one alternative embodiment, the opening angle of the groove is adapted to the edge angle of the photovoltaic panel frame to engage and guide at the edge of the seam during cleaning.

[0013] Secondly, this disclosure also provides a gap-filling mechanism for photovoltaic panel production, comprising: a cleaning section; the cleaning section comprising: an air pipe adapted to introduce gas; a cleaning head disposed at the tail end of the air pipe and connected to the air pipe, the cleaning head having a circular cross-section at its head and an elliptical flat cross-section at its tail end, adapted to increase the air pressure at the tail end of the cleaning head; the cleaning head having a groove to form a tongue at its tail end, the opening width of the groove tapering along its depth, the tongue being adapted to extend into the edge gap; at least one airflow outlet is provided on the inclined surface of the groove corresponding to the edge gap.

[0014] In one alternative embodiment, the end of the tongue is flattened, and its thickness is less than or equal to the width of the seam.

[0015] In one optional embodiment, the upper top surface and lower bottom surface of the tongue are provided with a plurality of toothed grinding strips.

[0016] In one alternative embodiment, the sidewall of the chute is a symmetrical inclined surface, the opening of which decreases linearly with depth; the sidewall of the chute is an arc-shaped curved surface, the opening of which narrows in an arc shape with depth; the sidewall of the chute is stepped, the opening of which decreases abruptly through one or more steps.

[0017] In one alternative embodiment, the opening angle of the groove is adapted to the edge angle of the photovoltaic panel frame to engage and guide at the edge of the seam during cleaning.

[0018] The beneficial effects of this utility model are that it provides a caulking mechanism for photovoltaic panel production. By setting a cleaning head and a tongue at its front end, the tongue can directly extend into the seam and scrape before applying glue. This mechanical scraping action can effectively remove and peel off stubborn, highly adhesive substances. Furthermore, the tongue is integrated with the airflow outlet to achieve a synergistic scraping and blowing mode, reducing the risk of poor adhesion caused by the isolation of the adhesive substances.

[0029] Research has revealed the following drawbacks of existing technologies: To improve the adhesion between the adhesive and the substrate, the surface is pre-treated before application. This involves using a high-pressure air nozzle integrated into the front of the caulking gun to clean the gaps to be filled. However, high-pressure air purging can only remove loose contaminants such as dust and debris within the gaps. It is almost ineffective in removing more adhesive contaminants (such as oil stains, sticky dirt, oxide layers, tiny cured adhesive dots, and protruding weld slag or burrs) that adhere to the surface of the support rails during transportation, storage, and installation. These stubborn deposits form a physical barrier layer, significantly reducing the effective bonding strength and durability of the sealant.

[0030] Therefore, how to solve the problem of stubborn residues on the substrate surface before applying adhesive is a technical problem that urgently needs to be solved in this field.

[0031] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] like Figures 1 to 3 As shown, some embodiments provide a caulking mechanism for photovoltaic panel production, including: a body 1; the body 1 is the main support and load-bearing structure of the mechanism, and its function is to integrate and fix the glue application part 2 and the cleaning part 3, to ensure the relative positional stability of them during operation and the rigidity of the overall mechanism, and to provide a stable foundation for automated or semi-automated caulking operations.

[0035] The glue applicator 2 is located inside the machine body 1, and the glue applicator head extends outside the machine body 1. This layout allows the power and control unit of the glue applicator 2 to be protected by the machine body 1, while the glue applicator head can be directly aligned with the edge seam 41 that needs to be filled, so as to achieve precise glue application.

[0036] The cleaning section 3 is located on the body 1. Its core function is to thoroughly pre-treat the substrate surface on both sides of the seam 41 between the photovoltaic panel 4 frame and the bracket guide rail before the sealant is injected in the sealant application section 2, so as to ensure that the subsequent sealant can form a strong bond.

[0037] The cleaning unit 3 includes: an air pipe 31, which is disposed on the glue application unit 2 or the body 1; a cleaning head 32, which is disposed at the tail end of the air pipe 31 and communicates with the air pipe 31; a groove 321 is provided on the cleaning head 32 to form a tongue 322 at its tail end, the tongue 322 being adapted to extend into the edge seam 41; at least one airflow outlet 323 is provided on the inclined surface of the groove 321 corresponding to the edge seam 41.

[0038] Specifically, the cleaning section 3 includes a trachea 31, a cleaning head 32, a chute 321, a tongue 322, an airflow outlet 323, and a toothed grinding strip 324.

[0039] The air pipe 31 serves as a delivery channel for compressed air or other working gases. It is fixed by clamps to ensure the stability and reliability of the air supply line and prevent it from falling off or shifting during mobile cleaning.

[0040] The cleaning head 32 is located at the end of the air tube 31 and is connected to the air tube 31; the cleaning head 32 is a component that directly performs the surface cleaning function, and it receives high-pressure gas through the air tube 31.

[0041] The end of the tongue 322 is flat and its thickness is less than or equal to the width of the seam 41.

[0042] The cleaning head 32 has a groove 321. The design of the groove 321 makes the tail end of the cleaning head 32 form a specific structure; the tongue 322 is formed by the structure of the groove 321 and is suitable for extending into the edge 41; the tongue 322 is the key part to directly insert into the gap and perform the cleaning operation.

[0043] The end of the tongue 322 is flat and its thickness is less than or equal to the width of the slit 41. This flattened end design allows the tongue 322 to be smoothly inserted into the narrow slit 41 while maximizing access to the substrate surface (the guide rail and the lower surface of the frame) that needs to be cleaned, providing space and possibilities for subsequent cleaning actions.

[0044] At least one airflow outlet 323 is provided on the inclined surface of the chute 321 corresponding to the edge seam 41. The inclined design of the airflow outlet 323 enables the direction of the airflow to be precisely aligned with the substrate surface to be cleaned inside the edge seam 41; it can use high-pressure airflow to blow away the floating dust and loose contaminants attached to the substrate surface, which is the first step of cleaning.

[0045] The upper and lower surfaces of the tongue 322 are provided with a number of toothed grinding strips 324. The toothed grinding strips 324 are made of wear-resistant hard material. When the tongue 322 moves in the edge slit 41, these toothed grinding strips 324 will physically scrape and grind the surface of the substrate. The principle is to use mechanical friction to effectively remove stubborn deposits that cannot be removed by high-pressure airflow, such as oil stains, oxide layers, cured adhesive spots, welding slag burrs, etc.

[0046] The toothed abrasive strip 324 is used to break down the physical barrier layer, significantly activating the substrate surface and providing a clean and rough ideal bonding surface for the sealant, thereby greatly improving the bonding strength and long-term durability of the seal.

[0047] The opening width of the groove 321 tapers along its depth; the tapering design helps guide and position the cleaning head 32 as it approaches the seam 41, allowing the tongue 322 to be more accurately aligned and enter the seam 41.

[0048] It should be further explained that the sidewall of the slide 321 is a symmetrical inclined surface, and its opening decreases linearly with depth; the sidewall of the slide 321 is an arc-shaped curved surface, and its opening narrows in an arc shape with depth; the sidewall of the slide 321 is stepped, and its opening decreases abruptly through one or more steps.

[0049] The opening angle of the groove 321 is adapted to the edge angle of the photovoltaic panel 4 frame so as to engage and guide it to the edge of the seam 41 during cleaning. The angle adaptation design allows the cleaning head 32 to be stably "locked" on the edge of the seam 41 for operation. On the one hand, it provides good guidance to ensure that the cleaning path is consistent with the subsequent glue application path. On the other hand, it enhances the stability during operation, prevents the cleaning head 32 from shaking, and ensures the consistency and reliability of the cleaning effect.

[0050] Overall workflow: 1. Positioning and guidance: During operation, the machine body 1 moves the cleaning part 3 to the edge 41 of the photovoltaic panel 4; the groove 321 of the cleaning head 32 stably engages with and guides the edge of the edge 41 by means of its opening angle that matches the edge of the frame.

[0051] 2. Insertion and preliminary cleaning: The flat tongue 322 is smoothly inserted into the seam 41; at the same time, high-pressure gas delivered through the air pipe 31 is ejected from the air outlet 323 to perform preliminary cleaning of the photovoltaic panel 4 surface in the seam 41, removing floating dust and loose contaminants.

[0052] 3. Deep Mechanical Cleaning: As the mechanism moves along the edge seam 41, the toothed abrasive strips 324 on the upper and lower surfaces of the tongue 322 continuously scrape and grind the lower surface of the guide rail and component frame. This process effectively removes stubborn contaminants such as oil, oxide layer, and welding slag, and may slightly roughen the surface of the photovoltaic panel 4, increasing the surface area and improving adhesion performance.

[0053] 4. Sealing with sealant: After the pretreatment is completed in the cleaning section 3, the sealant application section 2 follows up by precisely injecting sealant into the thoroughly cleaned seam 41.

[0054] Final result: Due to the deep cleaning of the photovoltaic panel 4 surface, including air blowing and mechanical grinding, stubborn adhering substances are effectively removed, and a strong, continuous, and defect-free bonding interface can be formed between the sealant and the metal photovoltaic panel 4. This fundamentally solves the problem of sealing failure caused by poor bonding, and significantly improves the sealing reliability and long-term durability of photovoltaic power station installation. The entire process integrates cleaning and sealant application functions, with a high degree of automation, ensuring the consistency of treatment results and work efficiency.
