Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to adhesive applicator machines. Background Technology

[0002] In the photovoltaic industry, if categorized by upstream and downstream, it can be broadly divided into silicon, metallic silicon, polycrystalline silicon, silicon rods, silicon wafers, solar cells, modules, arrays, and power station systems. Power station systems can include photovoltaic modules, foundations, supports, combiner boxes, inverters, transformer substations, and finally, the power grid. Individual solar cells, due to their fragility and poor aging resistance, cannot be used directly as power sources. Therefore, they need to be welded, connected in series and parallel, and tightly sealed into modules for long-term use. Solar cell modules (photovoltaic modules) are the core and most important component of a solar power generation system. Their function is to convert solar energy into electrical energy, which is either stored in batteries in off-grid systems, connected to loads, or connected to the grid.

[0003] The production process of solar cell modules (photovoltaic modules) can be roughly divided into several steps, including string welding, layout, stacking, lamination, glass bonding, EL appearance testing, edge sealing, lamination, edge trimming, flipping inspection, framing, junction box assembly, potting, curing, cleaning, IV testing, insulation withstand voltage testing, EL testing, FQC appearance testing, grading, and packaging. Among these, the framing process involves applying silicone sealant into the slots of the frame using equipment, then pressing the two short frames and two long frames towards the center of the semi-finished module to complete the framing step.

[0004] However, during the process of pressing the two short frames and two long frames into the center of the semi-finished module, silicone can leak out from the joints of the two short and two long frames, causing dirt to accumulate on the solar cell module (photovoltaic module). Therefore, additional manpower is required for wiping after the framing process. Manual wiping has certain drawbacks; for example, it is inefficient, and prolonged repetitive work will inevitably affect the worker's performance, making it difficult to guarantee the quality of the wiped product. Furthermore, the need for additional manpower for manual wiping inevitably increases labor costs, which in turn increases manufacturing expenses. Utility Model Content

[0052] See Figures 1 to 4 As shown, this application provides a glue-removing machine, which is mainly used to remove excess glue generated during the production of photovoltaic modules. The glue-removing machine may include a frame 1000, a work platform 2000, a straightening mechanism 3000, a feeding mechanism 4000, and a cleaning robot 5000. See also... Figure 1 and Figure 2 As shown, the frame 1000 serves as the base for the work platform 2000, the alignment mechanism 3000, the feeding mechanism 4000, the cleaning robot 5000, and other machine parts. The frame 1000 can be configured with a suitable mechanical structure based on the assembly requirements of various machine parts. For example, the frame 1000 can adopt various mechanical structure types such as a frame, chassis, or frame body. The dimensions of the adhesive applicator (frame 1000 dimensions) can be set to 4650*2500*2300mm, with a positive and negative tolerance of 500mm. Those skilled in the art can perform targeted designs based on the assembly and overall requirements of the work platform 2000, the alignment mechanism 3000, the feeding mechanism 4000, the cleaning robot 5000, and other machine parts; no limitations are imposed here.

[0053] Continue reading Figure 2 As shown, the working platform 2000 is disposed on the frame 1000. For example, when the frame 1000 is a frame-like structure, the working platform 2000 can be disposed inside the frame-like structure. The working platform 2000 may be defined as having a supporting surface, which can be configured to support photovoltaic modules. A portion of the surface area of ​​the supporting surface is designated as a positioning and alignment area. The working platform 2000 can be a complete platform or a platform composed of several unit components. Therefore, the supporting surface formed by the working platform 2000 can be a complete surface or a non-complete surface. For example, when the working platform 2000 is composed of several unit components, there may be gaps between the unit components, so that the supporting surface may include several gaps. Those skilled in the art can configure the specific structure of the working platform 2000 according to actual needs to meet the support requirements of the photovoltaic modules; no limitations are imposed here.

[0054] The alignment mechanism 3000 is mounted on the frame 1000. The alignment mechanism 3000 can be configured to align the photovoltaic modules on the supporting surface with the positioning alignment area. Alignment between the photovoltaic modules to be cleaned and the positioning alignment area means that the photovoltaic modules can be moved into the positioning alignment area under the force driven by the alignment mechanism 3000. This ensures that the photovoltaic modules are positioned in a preset direction and location within the preset area before cleaning. Because after the photovoltaic modules are moved to the work platform 2000, their orientation and position may not be suitable for cleaning. For example, if the orientation and position of the photovoltaic modules do not conform to the preset state, it will lead to poor cleaning results or cleaning failure. Therefore, when the photovoltaic modules arrive at the work platform 2000, the alignment mechanism 3000 aligns the photovoltaic modules with the positioning alignment area, ensuring that the photovoltaic modules are in the preset, most suitable orientation and position for the cleaning operation.

[0055] A feeding mechanism 4000 is mounted on the frame 1000 and configured to transfer wiping components to the supporting surface of the work platform 2000. The wiping components may include materials such as wiping cotton and wiping cloth for removing adhesive. The feeding mechanism 4000 can continuously provide wiping components as needed for adhesive removal. A cleaning robot 5000 is mounted on the frame 1000 and configured to grasp the wiping components and control them to clean the areas of the photovoltaic modules to be cleaned. Therefore, as the feeding mechanism 4000 continuously provides wiping components, the cleaning robot 5000 can continuously acquire new wiping components as needed, using them to clean the areas of the photovoltaic modules to remove excess adhesive.

[0056] Continue reading Figure 2 As shown, in one embodiment, the adhesive applicator may further include an adsorption mechanism 2100, which is disposed on the work platform 2000 and configured to adsorb photovoltaic modules located on the support surface. The adsorption mechanism 2100 may employ a structure with vacuum adsorption capabilities, such as an adsorption plate, enabling it to adsorb the photovoltaic modules located on the work platform 2000 onto the support surface of the work platform 2000 based on vacuum adsorption. Because the cleaning robot 5000 applies a cleaning force to the area of ​​the photovoltaic modules to be cleaned during the cleaning process, this force can be used to control the wiping component to remove excess adhesive.

[0057] Therefore, to prevent the force from unintentionally moving the photovoltaic module during the adhesive application process, it is necessary to maintain the stability of the photovoltaic module during the adhesive application process. To achieve this, the aforementioned adsorption mechanism 2100 can be used to adsorb the photovoltaic module, thereby keeping the photovoltaic module in a constant position during the adhesive application process, ensuring the stability and effectiveness of the adhesive application. In this case, based on the cooperative arrangement of the adsorption mechanism 2100 on the working platform 2000, the platform can become a vacuum adsorption platform, which can not only support the photovoltaic module but also keep the photovoltaic module in a constant position through vacuum adsorption.

[0058] Regarding the aforementioned alignment mechanism 3000, the alignment method can be various, such as pushing, pulling, or clamping, to achieve the alignment movement of the photovoltaic module towards the positioning alignment area. For example, in one embodiment, the alignment mechanism 3000 may include telescopic devices 3100, and the number of telescopic devices 3100 is configured to be at least two. For example, the number of telescopic devices 3100 may be two, three, four, or more, which is not limited here. Several telescopic devices 3100 may be distributed around the periphery of the working platform 2000, such that the telescopic devices 3100 can be configured to extend or retract in the direction of the working platform 2000. When the telescopic device 3100 extends, it can move towards the photovoltaic module, thereby touching the photovoltaic module and pushing the photovoltaic module on the supporting surface to move. When several telescopic devices 3100 push the photovoltaic module in several different directions around the photovoltaic module, the photovoltaic module can be gradually aligned to the positioning alignment area based on the common pushing action.

[0059] Regarding the aforementioned feeding mechanism 4000, in one embodiment, the feeding mechanism 4000 may include a feeding track 6100, an adsorption device, and a driving device. The feeding track 6100 includes an X-axis track, a Y-axis track, and a Z-axis track, which are respectively arranged along the X-axis, Y-axis, and Z-axis in space. Therefore, the adsorption device is movably disposed on the feeding track 6100 and can move to any position in three-dimensional space along the X-axis track, Y-axis track, and Z-axis track of the feeding track 6100. At this time, the adsorption device is configured to adsorb or release the wiping item, that is, to grasp the wiping item and move the wiping item to the working platform 2000.

[0060] The driving device is connected to the adsorption device and is configured to drive the adsorption device to move along at least one of the X-axis, Y-axis, and Z-axis tracks of the feeding track 6100, controlling the movement of the adsorption device from the position where the wiping item is gripped to the working platform 2000. For example, the adsorption device uses vacuum adsorption to transport the wiping item. Upon receiving a control command, the driving device can control the adsorption device to move along the X-axis and Y-axis tracks, causing the adsorption device to travel along the X-axis and Y-axis tracks to above the wiping item to be gripped. At this point, the driving device can control the adsorption device to move downwards along the Z-axis track to the wiping item, then vacuum adsorb the wiping item, and then lift the wiping item along the Z-axis track. The driving device can continue to control the adsorption device to move along the X-axis and Y-axis tracks, moving the wiping item to the working platform 2000.

[0061] In one embodiment, the adhesive application machine may further include a loading rack 6000, which is movably mounted on the frame 1000. The loading rack 6000 is configured to accommodate a plurality of wiping components, and the loading mechanism 4000 is configured to transfer the wiping components from the loading rack 6000 to the supporting surface of the work platform 2000. The loading rack 6000 is provided with a plurality of receiving chambers, each of which is configured to accommodate at least one wiping component. The frame 1000 is provided with a rack track, along which the loading rack 6000 is movably assembled. For example, the length of the loading rack 6000 is 1100±50mm, and the width of the loading rack 6000 is 30±10mm. The loading rack 6000 may be evenly distributed into eight rectangular slots, each slot having a height capable of accommodating approximately 300 pieces of wiping sponges, wiping cloths, or other wiping components (300 depending on production capacity). Therefore, a total of 2,400 wiping parts can meet the production capacity of a single line and a single shift. The 6,000 material racks are pulled out through the material rack track and can be manually replenished.

[0062] In one embodiment, the cleaning robot 5000 may include a multi-axis robot and a gripping device 5200. The multi-axis robot includes a front robotic arm, an end robotic arm 5100, and several intermediate robotic arms, which are sequentially and movably connected. The front robotic arm is movably connected to the end robotic arm 5100 via the intermediate robotic arms. The gripping device 5200 is disposed on the end robotic arm 5100 and configured to grip and wipe the cleaning component. In one embodiment, the number of cleaning robots 5000 is configured to be two, with the two cleaning robots 5000 located symmetrically on both sides of the work platform 2000. The area to be cleaned for the photovoltaic modules is configured as four corners of the modules, and each cleaning robot 5000 is configured to clean two corners of the modules.

[0063] In addition, the area to be cleaned on the photovoltaic module can be configured to other locations. For example, the module to be cleaned can be set to the long frame, short frame, or any surface of the photovoltaic module that needs to be wiped clean. Moreover, the object to be wiped clean is not limited to spilled glue, but can also be dust or other dirt. Therefore, those skilled in the art can set the area to be cleaned on the photovoltaic module and the object to be cleaned according to actual needs, and no limitations are imposed here.

[0064] The multi-axis robot is configured as a six-axis robot, comprising four intermediate robotic arms connected sequentially. The lead end robotic arm is connected to the end robotic arm 5100 via the four intermediate arms. For example, the six-axis robot has a maximum working radius of 1500mm, a repeatability of ±0.05mm, and a six-joint motion speed ranging from 200° / s to 600° / s. Its main functions include gripping, handling, and wiping. The robot weighs 130±10KG. Its integrated, synchronous design allows it to handle a maximum load of 10 kg. The compact structure and control technology must meet the requirements for wiping radius and accuracy. The base mounting dimensions are 300*300 (4*Φ18mm). The gripping device 5200 can be designed as a structure composed of two telescopic cylinders, which can clamp and release the wiping component through relative extension and retraction.

[0065] In one embodiment, the adhesive wiping machine includes a material handling box 7000, which is movably mounted on the frame 1000 and configured to collect wiping parts. The dimensions of the material handling box 7000 can be set to 75*45*30mm (±15mm tolerance), and the material handling box 7000 can be embedded in a pre-reserved slot on the frame 1000 for collecting dirty wiping parts that have been used to wipe photovoltaic modules.

[0066] In one embodiment, the adhesive application machine includes a position sensor and a transport line 8000. The position sensor is mounted on the frame 1000 and configured to acquire position data of the photovoltaic module relative to the work platform 2000. The transport line 8000 is connected to the position sensor data and configured to transport the photovoltaic module to the work platform 2000 based on the position data. The position sensor can be a photoelectric sensor, etc. Therefore, when the photovoltaic module reaches the position sensed by the position sensor, it can stop moving. After the photovoltaic module stops, the alignment mechanism 3000 can align the photovoltaic module, ensuring that it is aligned to a preset positioning and alignment area, facilitating the subsequent wiping action by the cleaning robot 5000.

[0067] At this time, if the working platform 2000 is equipped with an adsorption mechanism 2100, the adsorption mechanism 2100 can be used to adsorb the photovoltaic module, so that the photovoltaic module can be aligned to the fixed alignment area. Of course, if the working platform 2000 is not equipped with an adsorption mechanism 2100, in order to ensure that the photovoltaic module does not undergo unexpected displacement during the wiping process, the alignment mechanism 3000 can also be used to contact the photovoltaic module, and the abutment of the alignment mechanism 3000 relative to the photovoltaic module can be used to keep the photovoltaic module from moving. Those skilled in the art can set it according to actual needs, and there is no limitation here.

[0068] The adhesive application machine may also include a central control console, which typically employs a layered architecture. The top layer of the central control console is the monitoring and management system, responsible for monitoring the overall equipment's operational status, task scheduling, and data management. The middle layer of the central control console is the core control unit, including a programmable logic controller (PLC) or an industrial computer (IPC). The lower layer contains the drive control for various actuators, such as motor drivers and solenoid valve controllers, directly controlling the joint motors and gripping devices of the cleaning robot 5000. The central control console receives instructions from the upper-level monitoring and management system and converts them into specific control signals for the lower-level actuators.

[0069] Therefore, based on the aforementioned adhesive applicator, the loading rack 6000 can be manually pulled out from the frame 1000 first, and the wiping component can be added inside the loading rack 6000. After adding the component, it can be pushed back into the frame 1000 to complete the loading action. The start operation is then initiated by resetting and turning on the start switch. When the photovoltaic module is transferred from other processes to the adhesive applicator, the alignment mechanism 3000 can perform alignment processing on the outer periphery of the photovoltaic module, allowing the photovoltaic module to align with the positioning alignment area on the supporting surface. At this time, if the work platform 2000 does not have the adsorption mechanism 2100, the alignment mechanism 3000 will not be released. If the adsorption mechanism 2100 is present, the alignment mechanism 3000 can be released after the adsorption mechanism 2100 has stably adsorbed the photovoltaic module.

[0070] The driving mechanism controls the adsorption device to move along the X-axis and Y-axis tracks, allowing it to travel along these tracks to a position above the wiping item to be grasped. At this point, the driving mechanism controls the adsorption device to move downwards along the Z-axis track to the wiping item, then vacuum-adsorbs it, and lifts it up along the Z-axis track. The driving mechanism can continue to control the adsorption device to move along the X-axis and Y-axis tracks, moving the wiping item to the working platform 2000. At this point, the adsorption mechanism 2100 of the working platform 2000 can adsorb the wiping item, and then the driving mechanism controls the adsorption device to move along the X-axis and Y-axis tracks, leaving the working platform 2000.

[0071] The end effector 5100 of the multi-axis robot controls the gripper 5200 to move to the position of the wiping component on the work platform 2000. The two telescopic cylinders of the gripper 5200 can open and clamp the wiping component through relative extension and retraction. Through the coordinated movement of the front end effector 5100, the end effector 5100, and several intermediate end effectors, the multi-axis robot can move the wiping component to the area to be cleaned on the photovoltaic module, wiping away any excess adhesive. For example, it can move to a corner of the short frame of the photovoltaic module, wiping from the short frame to the long frame, then changing direction to wipe from the long frame to the short frame, and finally wiping from the inside out at the joint between the long and short frames below the photovoltaic module. After this step, it moves to another corner and performs the same operation. Finally, it moves to the unloading turnover box 7000, releases the used wiping component, discards it, and repeats the process. Finally, once the unloading turnover box 7000 is full, it can be cleaned by personnel.

[0072] Therefore, the aforementioned adhesive application machine can perform multiple steps such as alignment, loading, adhesive application, and unloading after the photovoltaic modules have been transferred to the supplier. Utilizing the machine's automated programming, it achieves automatic adhesive application, resulting in a high degree of automation and efficiency, eliminating concerns about human fatigue or emotional factors. This automated adhesive application method reduces manpower and lowers manufacturing costs.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
