Description

Technical Field

[0001] This utility model relates to the field of solar panel conveyor belts, and in particular to a conveyor belt cleaning device. Background Technology

[0002] Conveyor belts are one of the most crucial pieces of equipment in the solar cell manufacturing process. They are responsible for transporting solar cells or other related materials in different production stages along the production line. To improve production efficiency and reduce human error, conveyor belts are typically integrated with a variety of intelligent functions.

[0003] Existing technologies, such as the utility model patent with publication number CN222248888U, disclose a waste collection device for a conveyor belt in solar cell production. This patent includes a conveyor belt body with a collection box on one side. Inside the collection box, an inclined support plate is slidably mounted. A warning structure is located at the bottom of the inclined support plate. When fully loaded, the electrode ring contacts the electrode block, triggering a warning energization to provide maintenance personnel with an alert to promptly clean the waste from the collection box. Activating a control switch rotates a lifting motor, which in turn rotates a lead screw, causing a sliding push plate to rise and lift the inclined support plate. The waste from the collection box is discharged along the inclined surface of the support plate through a discharge port on the side of the collection box. In special operating environments, the horizontal height of the inclined support plate can be adjusted by changing the downward position of the sliding push plate for better waste collection.

[0004] The inventors discovered that in the existing technology for solar cell production, the conveyor belt easily accumulates dust, leading to contaminated solar cells and affecting their efficiency and yield. Current belt cleaning primarily involves manual wiping with a lint-free cloth dampened with alcohol. However, alcohol is volatile, causing the belt surface to cool instantly and form a small liquid film, reducing the belt's coefficient of friction. This makes the silicon wafers prone to slippage during transport. Furthermore, alcohol-wiped belts are prone to aging and cracking, reducing their lifespan and increasing material costs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in cleaning conveyor belts.

[0006] To solve the above-mentioned technical problems, this utility model provides a conveyor belt cleaning device, comprising: two connecting frames, a bracket fixedly connected to the lower surface of the connecting frames, a conveyor belt installed on the inner wall of the connecting frames, a transmission device installed at the ends of the two connecting frames that are far apart from each other, the transmission device being connected to the conveyor belt, a cleaning structure provided on both sides of the two brackets, the cleaning structure including two fixed rods, the two fixed rods being fixedly connected to the two sides of the two brackets respectively, a slide rail fixedly connected to the upper surface of the fixed rods, a slider slidably connected to the inner wall of the slide rail, a spring provided inside the slide rail, the two ends of the spring being fixedly connected to the slider and the slide rail respectively, a connecting rod fixedly connected to the side of the two sliders that are close to each other, a rotating shaft rotatably connected to the inner wall of both ends of the connecting rod, a cleaning roller fixedly connected to the arc surface of the rotating shaft, a protective frame fixedly connected to the lower end of the slider, a sliding frame fixedly connected to the side of the connecting rod close to the slide rail, a screw threadedly connected to the inner wall of the sliding frame, the screw abutting against the slide rail.

[0007] The effect achieved by the above components is as follows: when the conveyor belt needs to be cleaned, the screw is turned to move it, the screw separates from the slide rail, and then the spring's rebound force drives the slider to move upward. The slider slides on the inner wall of the slide rail, the slider drives the connecting rod to move, the connecting rod drives the two rotating shafts to move, the rotating shafts drive the cleaning roller to move, and then the cleaning roller comes into contact with the conveyor belt. The slider drives the sliding frame to move, the sliding frame drives the screw to move, and after moving to the appropriate position, the screw is turned to fix it, and then the conveyor belt is started to run. The cleaning roller cleans the conveyor belt, and then the debris and dust fall into the protective frame.

[0008] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to one end of the screw near the slide rail.

[0009] The effect achieved by the above components is that the anti-slip pad can increase the friction between the screw and the slide rail, preventing slippage when the screw and the slide rail are fixed together.

[0010] Preferably, a limiting rod is fixedly connected inside the slide rail, and the limiting rod is slidably connected to the slider.

[0011] The effect achieved by the above components is that the limiting rod can limit the slider, preventing the slider from deviating when sliding on the inner wall of the slide rail, thus improving the stability of the slider sliding.

[0012] Preferably, the limiting rod has a circular cross-section, and the spring is sleeved on the arc surface of the limiting rod.

[0013] The effect achieved by the above components is that the limiting rod can limit the spring, prevent the spring from deforming during use, and improve the service life of the spring.

[0014] Preferably, the lower surfaces of the two fixed rods are provided with a collection structure, the collection structure including four auxiliary rods, the four auxiliary rods being fixedly connected to both ends of the two fixed rods respectively, the lower ends of the auxiliary rods being fixedly connected to an installation rod, the surface of the installation rods being slidably connected to two fixed frames, the side of the fixed frame near the protective frame being fixedly connected to a connecting block, and the end of the connecting block away from the fixed frame being fixedly connected to a collection box.

[0015] The effect achieved by the above components is as follows: when it is necessary to collect the debris and residue from cleaning, the collection box is pulled to move, the collection box moves the connecting block, the connecting block moves the fixed frame, then the fixed frame is aligned with the mounting rod, then the fixed frame is inserted into the mounting rod, and then the collection box is fixed on the mounting rod, and the collection box collects the debris and residue.

[0016] Preferably, handles are fixedly connected to both ends of the collection box, and the handles have a "U" shaped cross-section.

[0017] The effect achieved by the above components is that when it is necessary to pull the collection box, the handle can be pulled directly, and the handle will move the collection box, making it more convenient to move the collection box.

[0018] Preferably, a positioning rod is slidably connected to the inner wall of the fixed frame, and the positioning rod is fixedly connected to the mounting rod.

[0019] The effect achieved by the above components is that the positioning rod can limit the fixed frame and prevent the fixed frame from sliding when it is fixed on the mounting rod.

[0020] Compared with related technologies, the conveyor belt cleaning device provided by this utility model has the following beneficial effects:

[0021] By incorporating a cleaning structure, this device addresses the issue of dust accumulation on conveyor belts during solar cell production, which leads to dirty cells and negatively impacts efficiency and yield. Current belt cleaning primarily involves manual wiping with a lint-free cloth dampened with alcohol. However, alcohol's volatile nature causes instantaneous cooling of the belt surface, forming a micro-liquid film that reduces the belt's coefficient of friction. This results in slippage during silicon wafer transport, and the alcohol-washed belt is prone to aging and cracking, reducing its lifespan and increasing material costs. This new device offers convenient and thorough cleaning of the conveyor belt surface, allowing for varying degrees of cleaning to meet different needs. Furthermore, the cleaning roller can be separated from the conveyor belt when cleaning is not required, facilitating continuous cleaning of the conveyor belt.

[0022] By setting up a collection structure, the dust after the conveyor belt is cleaned can be easily collected, which can prevent the dust from scattering on the ground and greatly improve the cleanliness of the solar cell production environment. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 6The present invention provides a conveyor belt cleaning device, comprising: two connecting frames 2, a bracket 1 fixedly connected to the lower surface of the connecting frame 2, a conveyor belt 3 installed on the inner wall of the connecting frame 2, a transmission device 4 installed at the ends of the two connecting frames 2 that are far apart from each other, the transmission device 4 being connected to the conveyor belt 3 in a transmission manner, a cleaning structure 5 provided on both sides of the two brackets 1, and a collection structure 6 provided on the lower surface of the two fixed rods 504.

[0033] In the embodiments of this utility model, please refer to Figures 2 to 4The cleaning structure 5 includes two fixed rods 504, which are fixedly connected to the two sides of the two brackets 1 respectively. A slide rail 503 is fixedly connected to the upper surface of the fixed rod 504. A slider 512 is slidably connected to the inner wall of the slide rail 503. A spring 510 is provided inside the slide rail 503. The two ends of the spring 510 are fixedly connected to the slider 512 and the slide rail 503 respectively. A connecting rod 508 is fixedly connected to the side of the two sliders 512 that are close to each other. A rotating shaft 509 is rotatably connected to the inner wall of both ends of the connecting rod 508. A cleaning roller 501 is fixedly connected to the arc surface of the rotating shaft 509. A protective frame 502 is fixedly connected to the lower end of the slider 512. A sliding frame 507 is fixedly connected to the side of the connecting rod 508 that is close to the slide rail 503. A screw 505 is threadedly connected to the inner wall of the sliding frame 507. The screw 505 abuts against the slide rail 503. When the conveyor belt 3 needs cleaning, the screw 505 is turned to move it, separating the screw 505 from the slide rail 503. Then, the rebound force of the spring 510 drives the slider 512 to move upward. The slider 512 slides on the inner wall of the slide rail 503. The slider 512 drives the connecting rod 508 to move, which in turn drives the two rotating shafts 509 to move. The rotating shafts 509 drive the cleaning roller 501 to move, and then the cleaning roller 501 comes into contact with the conveyor belt 3. The slider 512 drives the sliding frame 507 to move, and the sliding frame 507 drives the screw 505 to move. After moving to the appropriate position, the screw 505 is turned to fix it, and then the conveyor belt 3 is started to run. The cleaning roller 501 cleans the conveyor belt 3, and then the debris and dust fall into the protective frame 502. An anti-slip pad 506, which is a rubber pad, is fixedly connected to one end of the screw 505 near the slide rail 503. The anti-slip pad 506 increases the friction between the screw 505 and the slide rail 503, preventing slippage when the screw 505 and slide rail 503 are fixed together. A limiting rod 511 is fixedly connected inside the slide rail 503, and the limiting rod 511 is slidably connected to the slider 512. The limiting rod 511 limits the slider 512, preventing it from shifting when sliding on the inner wall of the slide rail 503, thus improving the stability of the slider 512's sliding. The limiting rod 511 has a circular cross-section, and a spring 510 is fitted onto the arc surface of the limiting rod 511. The limiting rod 511 also limits the spring 510, preventing deformation during use and extending its service life.

[0034] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The collection structure 6 includes four auxiliary rods 62, which are fixedly connected to both ends of two fixed rods 504. An installation rod 61 is fixedly connected to the lower end of each auxiliary rod 62. Two fixed frames 65 are slidably connected to the surface of the installation rod 61. A connecting block 67 is fixedly connected to the side of the fixed frame 65 closest to the protective frame 502, and a collection box 63 is fixedly connected to the end of the connecting block 67 furthest from the fixed frame 65. When it is necessary to collect the debris and residue, the collection box 63 is pulled to move, causing the connecting block 67 to move, which in turn causes the fixed frame 65 to move. The fixed frame 65 is then aligned with the installation rod 61 and inserted into the installation rod 61. The collection box 63 is then fixed to the installation rod 61 and collects the debris and residue. Handles 64 are fixedly connected to both ends of the collection box 63, and the handles 64 have a U-shaped cross-section. When it is necessary to move the collection box 63, the handle 64 can be pulled directly. The handle 64 moves the collection box 63, making it easier to move. A positioning rod 66 is slidably connected to the inner wall of the fixed frame 65, and the positioning rod 66 is fixedly connected to the mounting rod 61. The positioning rod 66 can limit the fixed frame 65 to prevent it from sliding when it is fixed on the mounting rod 61.

[0035] The working principle of the conveyor belt cleaning device provided by this utility model is as follows: When it is necessary to clean the conveyor belt 3, the screw 505 is turned to move, the screw 505 separates from the slide rail 503, and then the rebound force of the spring 510 drives the slider 512 to move upward. The slider 512 slides on the inner wall of the slide rail 503, and the slider 512 drives the connecting rod 508 to move. The connecting rod 508 drives the two rotating shafts 509 to move, and the rotating shafts 509 drive the cleaning roller 501 to move. Then the cleaning roller 501 comes into contact with the conveyor belt 3, wherein the slider 512 drives the sliding frame 507 to move, and the sliding frame 507 drives the screw 505 to move. When it moves to the point of contact... After positioning, screw 505 is tightened for fixation, and then the conveyor belt 3 is started to operate. The cleaning roller 501 cleans the conveyor belt 3, and then the debris and dust fall into the protective frame 502. The anti-slip pad 506 can increase the friction between the screw 505 and the slide rail 503, preventing slippage when the screw 505 and the slide rail 503 are fixed together. The limiting rod 511 can limit the slider 512, preventing the slider 512 from deviating when sliding on the inner wall of the slide rail 503, thus improving the stability of the slider 512's sliding. The limiting rod 511 can also limit the spring 510, preventing the spring 510 from deforming during use, thus improving the service life of the spring 510.

[0036] When it is necessary to collect debris and residue, pull the collection box 63 to move it. The collection box 63 moves the connecting block 67, which in turn moves the fixing frame 65. Then, the fixing frame 65 is aligned with the mounting rod 61 and inserted into the mounting rod 61. The collection box 63 is then fixed to the mounting rod 61. The collection box 63 collects debris and residue. When it is necessary to pull the collection box 63, the handle 64 can be pulled directly. The handle 64 moves the collection box 63, making it easier to move the collection box 63. The positioning rod 66 can limit the fixing frame 65 to prevent it from sliding when it is fixed on the mounting rod 61.
