Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt cleaning, in particular to a conveyor belt surface cleaning mechanism. Background Art

[0002] During the production and processing of silicon wafers, conveyor belts are required to transport them. During the conveying process, dust and impurities on the surface of the silicon wafers will fall and adhere to the conveyor belts. In order to ensure the stability of the conveyor belts during the conveying process and avoid affecting the subsequent conveying of silicon wafers, it is usually necessary to use corresponding cleaning mechanisms to clean the conveyor belts. However, the existing conveyor belt cleaning mechanisms still have the following shortcomings in actual use:

[0003] Traditional conveyor belts usually do not have a structure to clean themselves during operation and need to be manually cleaned after use. Therefore, it is impossible to keep the surface of the conveyor belt clean in real time, which can easily cause impurities to adhere to different workpieces and affect the stability of workpiece transportation. In response to the above problems, it is urgently necessary to innovate the design based on the original conveyor belt cleaning mechanism. Utility Model Content

[0004] The purpose of the present utility model is to provide a conveyor belt surface cleaning mechanism to solve the problem proposed in the above background technology that traditional conveyor belts usually do not have a structure for cleaning themselves during operation and need to be manually cleaned after use. Therefore, it is impossible to keep the surface of the conveyor belt clean in real time, which easily causes impurities to adhere to different workpieces and also affects the stability of the workpiece transportation.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a conveyor belt surface cleaning mechanism is provided, which is provided with a support base, a drive shaft is passed through the interior of the support base, and a conveyor belt is provided on the outside of the drive shaft through a pulley sleeve, the conveyor belt at the upper end is driven by a transmission shaft, and the transmission shaft is provided on the side of a support plate, the support plate is fixed to the side of the support base, and the conveyor belt is symmetrically distributed about the support plate;

[0006] It includes: an air delivery mechanism, which is arranged at the end of the driving shaft, and the air delivery mechanism generates negative pressure gas and delivers it to the support plate. Both sides of the support plate are provided with guiding mechanisms, and the guiding mechanisms are used to accelerate the falling of impurities on the conveyor belt.

[0007] Preferably, the gas delivery mechanism includes a fan blade fixedly mounted on the end of the drive shaft, and a protective box is provided on the outer side of the fan blade, and the protective box is fixed on the support seat. The negative pressure gas generated by the rotation of the fan blade can be transmitted to the fixed cavity through the gas delivery pipe.

[0008] Preferably, the protective box is connected to the fixed cavity through an air pipe, and the air pipe is fixed between the protective box and the support plate, and the fixed cavity is arranged inside the support plate. When the negative pressure gas is transmitted to the inside of the fixed cavity, impurities on the conveyor belt can be sucked in through the feed hole.

[0009] Preferably, feed holes are reserved on both sides of the support plate, and the feed holes are evenly distributed. Through the evenly distributed feed holes, comprehensive absorption of impurities on the conveyor belt can be achieved.

[0010] Preferably, the guiding mechanism includes a first gear fixedly mounted on the outside of the transmission shaft, and the range of the tooth blocks on the first gear is half of its circumference. When the transmission shaft rotates, it can drive the first gear to rotate, and then drive the movable shaft to rotate through meshing transmission with the second gear.

[0011] Preferably, the side of the first gear is meshed with the second gear, and a movable shaft is fixedly passed through the interior of the second gear, and the movable shaft bearing passes through the interior of the support plate. Since the first gear is a half-gear structure, when it is not meshed with the second gear, the second gear can be driven to rotate in the opposite direction by the rebound resilience of the spring.

[0012] Preferably, a spring is wound around the middle of the movable shaft to reset it, and guide plates are fixed to both ends of the movable shaft. When the movable shaft rotates, the guide plates can be driven to rotate and knock between the conveyor belts.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the conveyor belt surface cleaning mechanism can clean the impurities adhering to the surface of the conveyor belt in a timely manner during operation, so there is no need for subsequent manual cleaning, and impurities on the conveyor belt are prevented from adhering to other workpieces. At the same time, the stability of the conveying process can be ensured. The specific contents are as follows:

[0014] 1. When the drive shaft drives the fan blades to rotate, the negative pressure gas generated can enter the protective box and then be transmitted to the fixed cavity through the gas pipe. In this way, the impurities on the surface of the conveyor belt passing through both sides of the support plate can be sucked into the fixed cavity through the feed hole, achieving preliminary cleaning of the conveyor belt;

[0015] 2. The meshing transmission of the first gear and the second gear drives the movable shaft and the guide plate to rotate synchronously. Since the first gear is a half-gear structure, when the first gear is not meshed with the second gear, the movable shaft and the guide plate are driven to rotate in opposite directions by the resilience of the spring. Therefore, the guide plate is repeatedly rotated up and down to knock on the conveyor belt, thereby accelerating the separation of impurities on its surface and improving the cleaning efficiency.
