Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cells, and in particular to a high-temperature cloth cleaning device for a photovoltaic module laminator. Background Technology

[0002] In the production of solar cell modules, laminators are key manufacturing equipment used to laminate solar cells with other materials to form modules. However, during the lamination process, adhesive often overflows from inside the module and adheres to the surface of the high-temperature resistant cloth used to transport the modules. This adhesive residue can adversely affect the lamination quality of subsequent modules; therefore, regularly cleaning the high-temperature cloth is a necessary maintenance step.

[0003] Currently, laminators are typically equipped with roller brush cleaning systems, where a motor drives the brush to clean the surface of the high-temperature fabric. While some laminators are equipped with such systems, their effectiveness in removing stubborn EVA and butyl adhesives from the fabric is limited. This necessitates periodic manual intervention for tedious and time-consuming cleaning operations, increasing labor costs and impacting the continuous operation and overall capacity of the production line due to frequent interruptions. Therefore, a new type of high-temperature fabric cleaning system for laminators is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing cleaning devices are unable to remove residual adhesive.

[0005] This utility model provides a high-temperature cloth cleaning device for a photovoltaic module laminator, comprising:

[0006] Drive mechanism;

[0007] A scraper, which is fixedly mounted on the drive mechanism;

[0008] A cleaning line, which is placed on the scraper;

[0009] When the high-temperature cloth moves to the cleaning device, the drive mechanism drives the scraper to move, so that the cleaning line comes into contact with the surface of the high-temperature cloth and reciprocates along the surface of the high-temperature cloth to scrape it off.

[0010] Furthermore, the driving mechanism includes a first drive and a second drive, with the output end of the second drive connected to the first drive;

[0011] The scraper is fixedly mounted on the first drive and is used to realize the movement and positioning of the scraper.

[0012] Furthermore, it also includes a roller for supporting the high-temperature cloth, and the cleaning line scrapes the surface of the high-temperature cloth against the roller.

[0013] Furthermore, the high-temperature cloth is provided with a connecting rod. When the connecting rod approaches the cleaning device, the second drive retracts; when the connecting rod moves away from the cleaning device, the second drive extends.

[0014] Furthermore, when the second drive extends, the first drive causes the scraper to reciprocate in a direction perpendicular to the running direction of the high-temperature cloth.

[0015] Furthermore, it also includes a front sensor switch and a rear sensor switch, which are fixedly installed on the conveyor frame and arranged sequentially along the running direction of the high-temperature cloth, for detecting the position of the high-temperature cloth connecting rod.

[0016] Furthermore, it also includes a magnetic switch, which is disposed at both ends of the second drive and is used to detect the position of the scraper.

[0017] Furthermore, the scraper has a U-shaped structure, and each end of the U-shaped structure is provided with a groove for fixing the cleaning line, the groove having a depth of 2mm-3mm.

[0018] Furthermore, the cleaning line is a stainless steel wire with a diameter of 0.1mm-0.3mm, and the length of the cleaning line is 200mm-300mm.

[0019] Furthermore, the scraper is connected to the drive mechanism via a bracket, and the bracket is threadedly connected to the first drive mechanism.

[0020] Furthermore, the bracket is made of aluminum alloy and has a wall thickness of 3mm-5mm.

[0021] Furthermore, the bracket is provided with adjusting screws at both ends, which are used to adjust the tightness of the cleaning line.

The diagrams illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being broadly known to those skilled in the art and is not intended to limit the present invention.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0031] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0032] Please refer to Figure 4 The existing high-temperature cloth cleaning device uses a roller brush motor 22 to drive the roller brush 21 to rotate and clean the high-temperature cloth 2 of the laminator. However, it is difficult to remove the EVA glue and butyl glue adhering to the high-temperature cloth 2.

[0033] Based on the above, this embodiment provides a high-temperature cloth cleaning device for a photovoltaic module laminator. Please refer to [link / reference]. Figure 1 ,include:

[0034] Drive mechanism;

[0035] Scraper 35, the scraper 35 is fixedly mounted on the drive mechanism;

[0036] Cleaning line 44, the cleaning line 44 being placed on the scraper 35;

[0037] When the high-temperature cloth 2 moves to the cleaning device, the driving mechanism drives the scraper 35 to move, so that the cleaning line 44 is in contact with the surface of the high-temperature cloth 2 and reciprocates along the surface of the high-temperature cloth 2 to scrape it off.

[0038] Furthermore, the driving mechanism includes a first drive 32 and a second drive 31, with the output end of the second drive 32 connected to the first drive 31; the scraper 35 is fixedly mounted on the first drive 32 to realize the movement and positioning of the scraper 35.

[0039] Specifically, when the high-temperature cloth 2 moves to the position of the cleaning device, the drive mechanism starts working. The drive mechanism drives the scraper 35 to move, which is designed so that the cleaning line 44 can closely adhere to the surface of the high-temperature cloth 2, thereby performing the cleaning or scraping operation. The drive mechanism consists of two parts: a first drive 32 and a second drive 31. These two parts work together to provide the necessary power and precise control. The output end of the second drive 31 is connected to the first drive 32: this means that the second drive provides power to the first drive, or the second drive is the power source for the first drive; the two are functionally connected and work together to complete the driving task.

[0040] In this embodiment, the first drive 32 is a rodless cylinder, and the second drive 31 is a telescopic cylinder. Specifically, a rodless cylinder is a cylinder that does not require a piston rod; it moves linearly within the cylinder via a slider, rather than a piston rod. This design provides smoother and more precise motion. In this embodiment, the piston rod of the telescopic cylinder is fixed to the rodless cylinder. This means that when cleaning is required, the telescopic cylinder extends accordingly, pushing the rodless cylinder closer to the high-temperature cloth. As an example, the cleaning line 44 can be made of steel wire, which can withstand high-intensity cleaning operations without easily breaking or deforming.

[0041] For further details, please refer to... Figure 3 It also includes a roller 1 for supporting the high-temperature cloth 2, and the cleaning line 44 scrapes the surface of the high-temperature cloth 2 against the roller 1.

[0042] Specifically, roller 1 provides a stable support platform for high-temperature cloth 2, ensuring that cloth 2 maintains appropriate tension and flatness during the cleaning process. As high-temperature cloth 2 passes roller 1, it forms a relatively hard working surface, where the cleaning line 44 scrapes against the surface of cloth 2. This design utilizes the rigid support characteristics of roller 1, allowing the steel wire cleaning line 44 to contact the surface of high-temperature cloth 2 at the optimal angle and pressure, effectively removing residual adhesive 3 and other dirt. Simultaneously, the curved surface of roller 1 allows the cleaning line 44 to contact the high-temperature cloth 2 along a certain curvature, increasing the contact area and improving cleaning efficiency. As a preferred example, roller 1 can also have a heat dissipation function, helping to maintain a suitable temperature for high-temperature cloth 2 during cleaning and preventing heat accumulation that could reduce cleaning effectiveness or damage the material.

[0043] Furthermore, the high-temperature cloth 2 is provided with a connecting rod 33. When the connecting rod 33 approaches the cleaning device, the second drive 31 retracts; when the connecting rod 33 moves away from the cleaning device, the second drive 31 extends.

[0044] Furthermore, when the second drive 31 extends, the first drive 32 drives the scraper 35 to reciprocate in a direction perpendicular to the running direction of the high-temperature cloth 2.

[0045] Please refer to Figure 1The connecting rod 33 is used to connect the high-temperature cloth. In this embodiment, the high-temperature cloth is made up of multiple pieces of high-temperature cloth 2 connected together, with each piece connected by the connecting rod 33. Since the connecting rod 33 protrudes above the surface of the high-temperature cloth 2, when the connecting rod 33 is detected to be close to the cleaning device, the second drive 31 retracts, thereby removing the scraper 35 from the surface of the high-temperature cloth 2 to prevent the cleaning device from colliding with the connecting rod 33. When the connecting rod 33 moves away from the cleaning device, the second drive 31 extends, allowing the scraper 35 to get closer to the surface of the high-temperature cloth 2, ready for cleaning. The first drive 32 drives the scraper 35 to reciprocate along a direction parallel to the movement of the high-temperature cloth 2. This movement ensures that the scraper 35 can evenly scrape off the residual adhesive 3 from the surface of the high-temperature cloth 2 without damaging the fabric.

[0046] Furthermore, it also includes a front sensor switch 37 and a rear sensor switch 36, which are fixedly installed on the conveyor frame and arranged sequentially along the running direction of the high-temperature cloth 2, and are used to detect the position of the connecting rod 33 of the high-temperature cloth 2.

[0047] Specifically, the front sensor switch 37 is located at the front end of the first drive 32's travel stroke, near the starting position of the slider's movement path. Its main function is to detect whether the connecting rod 33 of the high-temperature cloth 2 has reached or exceeded the starting point of the first drive 32's travel stroke. This confirms the correct position of the high-temperature cloth 2 before the cleaning process begins, preventing the equipment from starting without the high-temperature cloth 2 being correctly positioned, thus avoiding equipment damage or safety accidents. Similarly, the rear sensor switch 36 is located at the rear end of the first drive 32's travel stroke, near the end point of the slider's movement path. Its function is to detect whether the connecting rod 33 of the high-temperature cloth 2 has reached or exceeded the end point of the first drive 32's travel stroke. This confirms at the end of the cleaning process whether the high-temperature cloth 2 has completely passed through the cleaning area, ensuring the integrity of the cleaning process.

[0048] As the connecting rod 33 moves within the laminator, the front sensor switch 37 and the rear sensor switch 36 detect its position. If the connecting rod 33 triggers the front sensor switch 37, the system knows that the connecting rod 33 is approaching and retracts the second drive 31; if the rear sensor switch 36 is triggered, the system knows that the connecting rod 33 is moving away and extends the second drive 31 to continue the cleaning process. These two sensors enable the cleaning device to automatically detect the position of the high-temperature cloth 2 and automatically control the movement of the second drive 31 and the scraper 35 based on this information, while cooperating with the first drive 32 to achieve an automated cleaning process. Furthermore, these sensors also provide safety protection. If an abnormality occurs during the cleaning process, such as the connecting rod 33 of the high-temperature cloth 2 not moving correctly, the sensors can immediately stop the movement of the second drive 31 and the first drive 32 to prevent equipment damage or personal injury.

[0049] Furthermore, it also includes a magnetic switch 34, which is disposed at both ends of the first drive 32 and is used to detect the position of the first drive 32.

[0050] In one possible embodiment of this invention, the stroke of the first drive 32 can be precisely controlled by the detection of the magnetic switch 34, ensuring that the scraper 35 reciprocates within a predetermined range, avoiding damage to the equipment or poor cleaning effect caused by exceeding the limits. The magnetic switch 34 also serves as a safety protection mechanism. When the first drive 32 accidentally reaches its limit position, the magnetic switch 34 can immediately send a signal, causing the control system to stop the action of the first drive 32, preventing equipment damage. In automated production lines, the signal from the magnetic switch 34 can be fed back to a PLC (Programmable Logic Controller) or other control units to achieve automatic control of the scraper 35's movement. For example, the cleaning frequency and stroke of the scraper 35 can be automatically adjusted according to a preset program. When equipment malfunctions, the position signal from the magnetic switch 34 can help operators quickly diagnose the problem, such as whether the first drive 32 is stuck or whether its stroke is abnormal.

[0051] For further details, please refer to... Figure 2 The scraper 35 has a U-shaped structure, and each end of the U-shaped structure is provided with a slot for fixing the cleaning line 44. The depth of the slot is 2mm-3mm.

[0052] Furthermore, the cleaning line 44 is a stainless steel wire with a diameter of 0.1mm-0.3mm, and the length of the cleaning line 44 is 200mm-300mm.

[0053] In one embodiment of this invention, the scraper 35 adopts a U-shaped structure. This design better adapts to the surface of the roller 1 of the high-temperature cloth 2 in the laminator, providing uniform cleaning pressure and effectively scraping away residues adhering to the high-temperature cloth 2. The two ends of the U-shaped scraper 35 are provided with slots for fixing the cleaning line 44. These slots are 2mm to 3mm deep, sufficient to accommodate and fix the cleaning line 44, while ensuring that the cleaning line 44 maintains the correct position and tension during the cleaning process. During the cleaning process, the U-shaped scraper 35 moves via the slider of the first drive 32, and the cleaning line 44 fixed at both ends moves along the surface of the roller 1 of the high-temperature cloth 2. Under the pressure of the scraper 35, the cleaning line 44 can penetrate deep into the fibers of the high-temperature cloth 2, scraping away adhering EVA glue, butyl glue, and other residues. Because the cleaning line 44 is fixed in the slots at both ends of the U-shaped scraper 35, it remains taut throughout the cleaning process and will not reduce the cleaning effect due to slack. This design improves the flexibility and efficiency of the cleaning device, while also extending the service life of the cleaning line 44 and reducing the frequency of maintenance and replacement. In this embodiment, the groove depth is 2mm, the diameter of the cleaning line is 0.2mm, and the length is 250mm.

[0054] Furthermore, the scraper is connected to the drive mechanism via a bracket, and the bracket 41 is threadedly connected to the first drive 32.

[0055] Furthermore, the bracket 41 is made of aluminum alloy material, and the wall thickness of the bracket 41 is 3mm-5mm.

[0056] Furthermore, the bracket 41 is provided with adjusting screws 43 at both ends, which are used to adjust the tightness of the cleaning line 44.

[0057] In this embodiment, the scraper 35 is fixedly mounted on the slider of the first drive 32 by a bracket 41. The bracket 41 is a device for fixing the scraper 35; one end is connected to the slider of the first drive 32, and the other end is used to mount the cleaning line 44. This ensures that the scraper 35 maintains the correct position and angle during the cleaning process.

[0058] Specifically, the bracket 41 is threadedly connected to the slider of the first drive 32 via a fixing screw 42. This connection method ensures the stability and accuracy of the bracket 41 during the movement of the first drive 32. The threaded connection provides reliable fixation while facilitating disassembly and reinstallation when necessary. The bracket 41 is made of aluminum alloy, which has good strength, light weight, and corrosion resistance, making it suitable for use in high-temperature environments and environments with certain mechanical loads. The wall thickness of the bracket 41 is 3mm to 5mm, ensuring its strength and stability, and enabling it to withstand certain pressure and impact during the cleaning process. Preferably, the wall thickness of the bracket 41 is 4mm.

[0059] The bracket 41 is also equipped with adjusting screws 43 at both ends, which are used to adjust the tension of the cleaning line 44. By adjusting the screws 43, it can be ensured that the cleaning line 44 maintains appropriate tension on the bracket 41, neither too loose, resulting in poor cleaning effect, nor too tight, resulting in premature fatigue or breakage of the cleaning line 44. This design improves the flexibility and adaptability of the cleaning device, allowing the tension of the cleaning line 44 to be adjusted according to different cleaning requirements and the condition of the high-temperature cloth 2, in order to obtain the best cleaning effect.

[0060] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
