Description

Technical Field

[0001] This utility model relates to the field of photovoltaic manufacturing equipment technology, and in particular to a labeling mechanism for photovoltaic module production lines. Background Technology

[0002] In the field of photovoltaic equipment, a photovoltaic module production line consists of several machine tool components customized according to the manufacturing process, arranged and controlled in a production flow, to complete the production process from raw materials and components to finished products in stages.

[0003] Busbars are conductive strips attached to photovoltaic cells, typically made of silver paste or copper. A photovoltaic panel contains many cells, and the current generated by these cells needs to be collected to form the output of the entire photovoltaic module. Busbars help improve the overall efficiency of the photovoltaic module by consolidating this current into one or a few main current paths.

[0004] During the assembly and manufacturing process of photovoltaic (PV) modules, especially after the installation and attachment of busbars and EVA gaskets, a glass plate is needed to cover them. Therefore, finished PV modules typically have two glass plates (or sheets) to enclose and protect the internal core components. For product traceability and other requirements, it is currently necessary to add easily scannable and tamper-proof labels during PV module production. Therefore, attaching labels between the two glass sheets (internal labeling) has become the preferred solution. However, current PV module production lines are highly automated, and relying on manual intervention for internal labeling would significantly impact efficiency and accuracy. Summary of the Invention

[0005] The purpose of this utility model is to provide an inner labeling mechanism for photovoltaic module production lines, which solves the technical problem of affixing labels inside double-layer glass in fully automated photovoltaic module production lines.

[0006] To achieve the above objectives, this utility model provides a labeling mechanism for a photovoltaic module production line, comprising a first horizontal transfer unit and its sliding frame mounted on a machine tool frame, a second horizontal transfer unit and its slider mounted on the sliding frame, a lifter and its irregularly shaped adapter mounted on the slider, a steering unit mounted on the platform plate of the irregularly shaped adapter, a swing-turning unit connected to the output shaft of the steering unit below the platform plate, and a labeling unit mounted on the outward end of the swing arm of the swing-turning unit. The labeling unit is driven to pick up the label to be labeled at the material picking station and aligns with the edge of the double-layer glass sheet of the photovoltaic module to affix the label between the glass layers.

[0007] Furthermore, the swing-turning unit is equipped with a pneumatically driven turntable, and a clamp is provided at the rotation axis of the turntable. The inward end of the swing rod is inserted into and fixed in the clamp and rotates in a controlled manner. The labeling unit is driven by the swing-turning unit and rotates 180° along the rotation center axis of the turntable.

[0008] Furthermore, the swing reversing unit is provided with inverted limiting protrusions on both sides of the turntable at the upper position, and the swing arm's rotation range is limited to the arm body touching the limiting protrusions.

[0009] Furthermore, the labeling unit consists of a base plate, a label adsorption plate, a buffer spring, and a glass sheet top support plate. The label adsorption plate is parallel to and movably mounted on the bottom side of the base plate, and the buffer spring is sandwiched between the two plates to maintain the top support state. The label adsorption plate is provided with an air channel. One end of the air channel is connected to an external air source, and the other end of the air channel is formed into an air hole facing the glass sheet top support plate.

[0010] Furthermore, a number of guide sliding groups are provided between the base plate and the label adsorption plate around the buffer spring to maintain the parallel state of relative movement of the two plates.

[0011] Furthermore, the glass sheet top support plate is mounted on the base plate and a gap is maintained between it and the label adsorption plate to accommodate the insertion of a glass sheet.

[0012] Furthermore, the irregularly shaped adapter frame is formed into an L-shaped folding plate frame and is provided with a triangular reinforcing plate to maintain the level of the platform plate.

[0013] Furthermore, a negative pressure gauge is also provided at the edge of the platform plate to monitor whether the tag is properly adsorbed.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When applied to a photovoltaic module production line, the multi-dimensional adjustable transfer unit and turning unit, especially the controlled 180° rotation swing turning unit, provide the labeling unit with the freedom to switch between different workstations and accurate positioning, and enable it to flexibly adjust to pick up materials downwards and attach them upwards. In specific process links of the photovoltaic module production line, it has achieved relatively ideal production efficiency and yield. Attached Figure Description

[0016] Figure 2 yes Figure 1 The diagram shows a close-up of the assembly of the swing-turning unit and the labeling unit in the labeling mechanism. Detailed Implementation

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master, and thus to make a clearer definition of the protection scope of this utility model. It should be understood that the specific embodiments described herein are merely used to explain this utility model and are not intended to limit this utility model.

[0018] like Figure 1 and Figure 2 As shown, this utility model provides a labeling mechanism for a photovoltaic module production line, including a first horizontal transfer unit 1, its drive motor 11, and a sliding frame 12 mounted on a machine tool frame, responsible for driving the suffix component (reduced step by step below) to move and position in the horizontal transverse direction (X-axis) of the machine tool; a second horizontal transfer unit 2, its slide rail body 21, and a slider 22 mounted on the sliding frame 12, responsible for driving the suffix component to move and position in the horizontal longitudinal direction (Y-axis) of the machine tool; and a lifter 3 and its irregularly shaped adapter 31 mounted on the slider 22, responsible for driving the suffix component in the vertical direction (Z-axis) of the machine tool. The first four axes of the photovoltaic module are designed for displacement and positioning. A steering unit 4, mounted on the platform plate 311 of the irregularly shaped adapter 31, drives the suffix component to rotate radially and position itself along a vertical axis in the XYZ coordinate system. A swing-rotating unit 5, connected to the output shaft of the steering unit below the platform plate 311, allows the swing arm to rotate 180 degrees around a horizontal axis while remaining parallel to the bottom glass sheet, based on its own positioning. A labeling unit 6, connected to the outward-facing end of the swing arm of the swing-rotating unit 5, is also included. This labeling unit 6 is driven to pick up the label to be applied at the material handling station and aligns with the edge of the double-layered glass sheet of the photovoltaic module, affixing the label between the glass layers. The transfer and positioning of these first four axes are common in various industrial control equipment, so detailed illustrations and basic operating instructions are omitted. However, the steering unit facilitates the application of labels facing one or more sides of the glass sheet, while the swing-rotating unit's design meets the actual working conditions of feeding the label face up and applying it face down, representing the main innovative design of this labeling mechanism.

[0019] From a further technical refinement and optimization perspective, the aforementioned swing-turning unit 5 is equipped with a pneumatically driven turntable 52, and a clamp 53 is located at the turntable's axis of rotation. The inward-facing end of the swing rod 51 is inserted into and fixed within the clamp 53 and rotates under control, while the outward-facing end of the swing rod 51 is integrated with the labeling unit 6. Thus, the labeling unit can be driven by the swing-turning unit to rotate 180° along the turntable's rotation axis. Combined with the labeling unit's own structural design, it can pick up and absorb the label to be labeled from top to bottom at the material picking station, and be driven to change the label's orientation, performing the labeling action from bottom to top at the desired labeling location. This realistically simulates the state of manual operation. In particular, to enhance the accuracy (i.e., levelness) of the positioning of the swing arm after each controlled turn, the swing arm turning unit is provided with inverted limiting protrusions on both sides of the turntable 52 at the upper position. The rotation range of the swing arm is limited to the arm body touching the limiting protrusions, thereby overcoming inertia and enhancing positioning accuracy.

[0020] Specifically, the labeling unit 6 consists of a base plate 61, a label adsorption plate 62, a buffer spring 64, and a glass sheet top support plate 63. The label adsorption plate 62 is parallel to and movably mounted on the bottom side of the base plate 61, and the buffer spring 64 is sandwiched between the two plates to maintain a top support state. This allows the label adsorption plate to obtain a buffer stroke during material picking and application, avoiding damage to the horizontal state and durability of the swing arm by the reaction force, while also reducing operating noise. In addition, several guide sliding groups are provided around the buffer spring 64 between the base plate 61 and the label adsorption plate 62 to maintain the parallel state of the relative movement of the two plates.

[0021] The label adsorption plate 62 has an internal air channel. One end of the air channel is connected to an external air source, and the other end is formed into an air hole on the material handling panel 6A facing the glass sheet support plate. This air hole is used to securely position the label during label picking, flipping, material handling, and application, preventing it from falling off or shifting. Meanwhile, the glass sheet support plate is connected to the base plate below via a connecting rod (not shown in the diagram), and a gap is maintained between it and the label adsorption plate to allow for the insertion of a single glass sheet (while also providing sufficient material handling space), providing back-side support during label application.

[0022] In addition, by Figure 1 As shown, the irregularly shaped adapter frame 31 is formed into an L-shaped folded plate frame and is equipped with a triangular reinforcing plate to maintain the level of the platform plate. A negative pressure gauge 7 is also installed at the edge of its platform plate to monitor whether the label is properly adsorbed. The detection probe of this negative pressure gauge is connected to the aforementioned air duct. If the label is accurately adsorbed during the material handling process, the air vents are blocked, and the air duct is under negative pressure. If the label is not properly adsorbed or some air vents are leaking, the negative pressure gauge detects a negative pressure imbalance, and the signal is fed back to the equipment operating system for reference.

[0023] In summary, the above introduction and detailed description of the labeling mechanism for photovoltaic module production lines demonstrate that this solution possesses substantial features and advancements: through multi-dimensional adjustable transfer and steering units, especially the controlled 180° rotation swing steering unit, it provides the labeling unit with freedom of switching between different workstations and accurate positioning, and enables it to flexibly adjust between downward material picking and upward attachment, achieving relatively ideal production efficiency and yield in specific process stages of photovoltaic module production lines.

[0024] In addition to the above embodiments, the present invention may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
