Description

Technical Field

[0002] Semiconductor materials are a type of electronic material that has semiconductor properties (conductivity is between conductors and insulators, and resistivity is approximately in the range of 1mΩ·cm to 1GΩ·cm) and can be used to make semiconductor devices and integrated circuits. The semiconductor material process requires work in a clean room, and workers also need to change into dust-free clothes and shoes, and pass through an air dust removal room to blow off dust before entering. The reason is that semiconductor materials are quite delicate and fragile, and any dust or improper touch or collision will damage the semiconductor material. Most semiconductor materials, such as solar panels, wafers and other components, must go through many procedures before completing the packaging, and the conveyor device must continuously move the position, and the movement accuracy is relatively high. The existing conveyor belt cannot be linked with the other devices, resulting in insufficient accuracy. Utility Model Content

[0021] Embodiment 1:

[0022] like Figure 1-2 As shown, a positioning transmission belt for the semiconductor industry includes a transmission belt composed of a frame 1, a driving device 2, a conveyor belt 3 and a positioning device 4, the positioning device 4 includes a rotating shaft 41, a transmission component 42 and a start-stop module 43, both ends of the rotating shaft 41 are arranged on the frame 1 through a bearing seat, one end of the transmission component 42 is transmission-connected to the output end of the driving device 2, and the other end of the transmission component 42 is transmission-connected to the rotating shaft 41, and sealing covers are arranged on both sides of the top of the frame 1, and the sealing covers are used to press the two sides of the conveyor belt 3 onto the surface of the frame 1, and sealing brushes are arranged on the contact surface between the sealing cover and the conveyor belt 3, and the surface of the sealing brush is in contact with the surface of the conveyor belt 3, and the transmission component 42 includes a gear belt and a protective cover, and the rotating shaft 41 is sleeved with a A driven pulley corresponding to the gear belt, and an active pulley corresponding to the gear belt are sleeved on the output shaft of the driving device 2. The gear belt is used for transmission, which reduces the sliding displacement caused by insufficient friction and better ensures the displacement accuracy of the conveyor belt. The start-stop module 43 includes induction blocks arranged on both sides of the conveyor belt 3 and a plurality of induction grooves arranged on the top of the frame 1. A plurality of induction blocks are evenly spaced on the inner surfaces of both sides of the conveyor belt 3, and a plurality of induction grooves for accommodating the induction blocks are evenly spaced and linearly arranged on the top of the frame 1. A photoelectric induction switch 5 is arranged inside each of the induction grooves, and the plurality of photoelectric induction switches 5 are connected in series. The induction block is hinged and fixed to the conveyor belt 3, and a slide groove for avoiding the movement of the induction block is provided on the frame 1.

[0023] like Figure 1-2As shown, a ring gear protrusion 6 is provided at the middle position of the inner wall of the conveyor belt 3, and a first gear is sleeved on the rotating shaft 41, and the ring gear protrusion 6 meshes with the first gear. The displacement accuracy of the conveyor belt can be increased by the mutual cooperation of the ring gear protrusion 6 and the first gear. Because it is provided at the middle position of the conveyor belt, the thickness of the middle position of the transmission belt is greater than that of the edge position, which increases the tensile strength of the conveyor belt and reduces the deformation of the conveyor belt. A tensioning wheel is provided on the frame 1, and a pressure sensor is provided on the surface where the tensioning wheel contacts the conveyor belt 3. The pressure value of the pressure sensor is maintained at a constant value, further ensuring the displacement accuracy of the conveyor belt.

[0024] Specific implementation process: the driving device 2 drives the rotating shaft 41 to rotate, so that the conveyor belt 3 is displaced. The sensing block leaves the receiving slot for a certain position and enters the next adjacent solute slot, and triggers the photoelectric sensing switch 5. The conveyor belt stops running and moves a distance. Because the position of the receiving slot is fixed, the size of the sensing block and the position on the conveyor belt are fixed, so the displacement of the conveyor belt each time is known and determined, and the displacement accuracy is extremely high. The displacement distance of the conveyor belt is guaranteed by various means, so that some components with high precision requirements can be installed accurately, reducing the requirements for positioning auxiliary tools for such components, greatly increasing production efficiency, and further increasing the automated production process.
