Description
Technical Field
[0001] This utility model relates to the field of photovoltaic manufacturing equipment technology, and in particular to a double-labeling machine 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] During the assembly and manufacturing process of photovoltaic modules, product upgrades based on customized requirements often necessitate attaching RFID tags and logos at intervals to the bottom of a glass sheet. In existing production lines, manual intervention in tag placement significantly impacts production efficiency, and even compromising placement accuracy and consistency. Furthermore, the tag picking direction is opposite to the placement direction, unavoidably requiring additional flipping actions after picking. Summary of the Invention
[0004] The purpose of this invention is to provide a dual-labeling machine for photovoltaic module production lines, which solves the technical problem of simultaneously affixing RFID tags and logos in a certain process step of a fully automated photovoltaic module production line.
[0005] To achieve the above objectives, this utility model provides a double-labeling machine for photovoltaic module production lines, featuring a machine frame with an independent side facing the glass sheet of the photovoltaic module. The machine frame is characterized by: a logo printer and an RFID tag generator arranged side-by-side at the bottom inner side; a suspended beam at the top of the machine frame for horizontal longitudinal displacement and positioning; and a logo-labeling unit and an RFID tag-labeling unit for horizontal lateral displacement and positioning. The logo-labeling unit has a first suction component with lifting, turning, and forward / backward swinging capabilities, while the RFID tag-labeling unit has a second suction component with lifting, turning, and forward / backward swinging capabilities. The two units are driven to adjust the material-picking distance of their respective suction components and the adhesion distance facing the glass sheet. The two suction components swing backward to pick up material from top to bottom, and swing forward to apply both types of labels upside down.
[0006] Furthermore, the logo-attaching unit includes a first lifter, a first adapter frame mounted on the sliding part of the first lifter, a first adjuster embedded in the horizontal platform plate of the first adapter frame, a first swing arm half-rotor mounted on the bottom output shaft of the first adjuster, and a first suction-attaching component mounted on the outer end of the first swing arm rod. The first suction-attaching component is externally connected to an air source and controlled to form a negative pressure for material picking and transfer. The RFID tag-attaching unit includes a second lifter, a second adapter frame mounted on the sliding part of the second lifter, a second adjuster embedded in the horizontal platform plate of the second adapter frame, a second swing arm half-rotor mounted on the bottom output shaft of the second adjuster, and a second suction-attaching component mounted on the outer end of the second swing arm rod. The second suction-attaching component is externally connected to an air source and controlled to form a negative pressure for material picking and transfer.
[0007] Furthermore, the first suction assembly and the second suction assembly have the same assembly structure. The first suction assembly is composed of a substrate, a material picking seat plate, a material picking end plate and a buffer spring. The substrate is integrally connected to the outer end of the corresponding first swing arm and moves in tandem. In the material picking state, the material picking seat plate is mounted parallel to the bottom side of the substrate and the buffer spring is sandwiched between the two for guiding movement. The material picking end plate can be replaced and mounted on the bottom side of the material picking seat plate.
[0008] Furthermore, the first and second swing arm half-rotors have the same assembly structure. The first swing arm half-rotor is equipped with a pneumatically driven turntable, and the first swing arm rod is orthogonally connected and fixed to the rotating shaft rod extending from the turntable, and is driven to rotate 180° along the rotation center axis of the turntable. The first swing arm half-rotor is provided with limiting protrusions on both sides of the rotating shaft rod to limit the two stroke endpoints of the first swing arm rod.
[0009] Furthermore, the first transfer frame is equipped with a first negative pressure gauge to monitor whether the Logo material is picked up in place, and the second transfer frame is equipped with a second negative pressure gauge to monitor whether the RFID tag material is picked up in place.
[0010] Furthermore, the machine frame is equipped with an industrial control unit and a control platform on one side surface for equipment debugging and parameter setting.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This dual-labeling machine is configured with labeling units independently for two types of labels, which can flexibly adjust to different spacings at the label picking station and the labeling station. By giving the labeling unit the ability to swing in a semi-circular manner, it provides an optimized way to connect the picking and labeling directions, which is conducive to improving production efficiency and yield.

[0016] 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.
[0017] like Figure 1 and Figure 4 As shown, this utility model provides a double-labeling machine for photovoltaic module production lines. It has a machine frame 1 that independently faces the side of the photovoltaic module glass sheet. The glass sheet to be processed will move towards or off the machine along the I / O direction shown in the figure. From the perspective of the processing operation: the bottom inner side of the machine frame 1 has a logo printer and an RFID tag generator arranged side-by-side. These are commercially available equipment, installed side-by-side on the inner platform of the machine frame only to accommodate heat dissipation and wiring. Therefore, the logos and RFID tags printed or output by these two devices will have a fixed interval, providing a basis for setting material handling parameters. The top of the machine frame 1 has a driven horizontal longitudinal displacement and positioning suspension beam 11, which can be considered a small gantry crane and is driven and guided to move horizontally. Its main function is to drive the unit components mounted on it to move back and forth between the material handling station and the labeling station. Specifically, the hanging beam is equipped with a logo-attaching unit 2 and an RFID tag-attaching unit 3, which are driven to move horizontally and position. The logo-attaching unit 21 is equipped with a first suction component 25 with lifting, turning and swinging capabilities, while the RFID tag-attaching unit 3 is equipped with a second suction component 35 with lifting, turning and swinging capabilities. The two units are driven to adjust the material-picking distance of their respective suction components and adjust the attachment distance of their respective suction components facing the glass sheet. The two suction components swing backward and pick up materials from top to bottom. The two suction components swing forward in an open position and simultaneously attach two types of labels from bottom to top at the mounting station.
[0018] about Figure 2 It should be briefly explained that the RFID tag unit 3 is shown in reverse from the inside out to illustrate its structural features. In actual assembly, it should be rotated from position A to position B, which is attached to the hanging beam 11.
[0019] Of course, the above-described material handling and mounting processes depend on the detailed structural design of the two units. Specifically, Figure 3 The logo-applying unit 2 shown is equipped with a first lifter 21 (preferably pneumatically driven) for height switching during material picking and application. Based on this, it also includes a first adapter frame 22 mounted on the sliding part of the first lifter, a first adjuster 23 embedded in the horizontal platform plate of the first adapter frame, a first swing arm semi-rotor 24 mounted on the bottom output shaft of the first adjuster, and a first suction-applying assembly 25 mounted on the outer end of the first swing arm. Thus, the first suction-applying assembly can achieve horizontal rotation and vertical semi-circular swing through the aforementioned progressively transmitted components, adjusting and switching the orientation and position of material picking or application. Furthermore, the first suction-applying assembly is connected to an external air source and controlled to form a negative pressure for material picking and transfer.
[0020] More specifically, the first suction assembly 25 is assembled from a substrate 251, a material-grabbing seat plate 252, a material-grabbing end plate 253, and a buffer spring 254. The substrate 251 is integrally connected to the outer end of the corresponding first swing arm 241 and moves integrally with it. In the material-grabbing state ( Figure 3 (View) The material picking plate 252 is mounted parallel to the bottom side of the base plate 251 and a buffer spring 254 is sandwiched between them. Parallel guiding movement is achieved by a number of guide components arranged around the spring. One or more specifications of material picking end plates can be replaced and mounted on the bottom side of the material picking plate. The air holes provided on the material picking end plates are connected to the air source and form a negative pressure for picking up materials and carrying the logo.
[0021] The first swing arm half-rotor 24 is equipped with a pneumatically driven turntable 242, and the first swing arm rod 241 is orthogonally mounted and fixed to the rotating shaft rod 243 extending from the turntable, and is driven to rotate 180° along the rotation center axis of the turntable. At the same time, due to the objective existence of the self-weight of the first suction assembly, the rotation process of the first swing arm rod needs to be limited by inertia. The first swing arm half-rotor 24 is provided with limiting protrusions 245 on both sides of the rotating shaft rod to limit the two end points of the first swing arm rod's stroke. The limiting protrusions are screws with adjustable downward depth.
[0022] Figure 4The RFID tag attaching unit 3 shown is equipped with a second lifter 31 (preferably pneumatically driven). Based on this, it also includes a second adapter 32 mounted on the sliding part of the second lifter, a second adjuster 33 embedded in the horizontal platform plate of the second adapter, a second swing arm half-rotor 34 mounted on the bottom output shaft of the second adjuster, and a second suction attachment assembly 35 mounted on the outer end of the second swing arm. Thus, the second suction attachment assembly can achieve horizontal rotation and vertical semi-circular swing through the aforementioned progressively driven components, adjusting and switching the orientation and position of material picking or attaching. Furthermore, the second suction attachment assembly is connected to an external air source and controlled to form a negative pressure for material picking and transfer. The assembly structure of the second suction attachment assembly and the first suction attachment assembly can be similarly referenced, as can the assembly structure of the second swing arm half-rotor and the first swing arm half-rotor, and therefore, detailed descriptions are omitted.
[0023] As technical support for the overall electronic and pneumatic control, the machine frame is equipped with an industrial control unit 4 and an external control platform 5 for equipment debugging and parameter setting. The details of the standard configuration are omitted.
[0024] In addition, the first adapter 22 is equipped with a first negative pressure gauge 61 to monitor whether the Logo has been properly picked up, and the second adapter 32 is equipped with a second negative pressure gauge 62 to monitor whether the RFID tag has been properly picked up. The detection probes of these two negative pressure gauges are connected to the air path of the corresponding suction assembly. If the material is accurately adsorbed during the picking process, the air vents are completely blocked, and a negative pressure state is maintained in the air path. If the material is picked up incorrectly or some air vents are leaking, the negative pressure measured by the negative pressure gauges will be unbalanced, and the signal will be fed back to the industrial control unit as a reference signal.
[0025] Assuming the interval between material pick-up points is greater than the labeling interval, the operation of this double-labeling machine can be understood from one work cycle: First, the two units move horizontally on the lifting beam, adjusting their respective suction components to correspond to the material pick-up points. Then, the horizontal longitudinal displacement of the lifting beam moves the two suction components closer to the material pick-up station. The first suction component, driven by the first lifter, descends to pick up the Logo and returns to its initial height. The second suction component, driven by the second lifter, descends to pick up the RFID tag and returns to its initial height. Next, the horizontal longitudinal displacement of the lifting beam moves the two units to a relatively open area between the material pick-up station and the labeling station. The two units then move closer together, aligning the two suction components with the preset labeling points. The first suction component is rotated by the first swing arm half-rotor, and the second suction component is rotated by the second swing arm half-rotor. Finally, the horizontal longitudinal displacement of the lifting beam moves the two units to the labeling station, where the two lifters raise their respective suction components upwards, affixing the Logo and RFID tag to the preset positions on the bottom surface of the glass sheet. The last two units are reset to the central open area, and the two suction components are flipped over to prepare for material picking.
[0026] In summary, the above introduction and detailed description of the dual-labeling machine solution for photovoltaic module production lines demonstrate that this solution possesses substantial features and advancements: the dual-labeling machine is configured with independent labeling units for two types of labels, can flexibly adjust to different spacings at the label picking and labeling stations, and provides an optimized approach for connecting the picking and labeling directions by giving the labeling units a semi-circular swing capability, which is conducive to improving production efficiency and yield.
[0027] 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.
