Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of silicon wafer transportation equipment, in particular to a conveying device for photovoltaic solar silicon wafers. Background Technique
[0002] Solar silicon wafers can be used for photovoltaic power generation only through the circuits on their surfaces. Currently, the most common production process for the circuits on the surfaces of silicon wafers is the screen printing method. The working principle of screen printing is that the paste passes through the mesh holes in the graphic part of the screen. A squeegee applies a certain pressure to the paste part of the screen and moves towards the other end of the screen at the same time. In this way, the paste is extruded from the mesh holes in the graphic part to the substrate by the squeegee during the movement and adheres to it, thus completing the printing process. The printing of the circuits on solar cells is mainly completed in three steps. First, the back electrode is printed, second, the back electric field is printed, and third, the front electrode is printed after the silicon wafer is turned over.
[0003] However, when the silicon wafer is transported on the conveyor belt, since the conveyor belt is running continuously, when the silicon wafer reaches the designated position, due to inertia, the silicon wafer will still continue to move. If a blocking object is directly placed, the silicon wafer is easily damaged after being impacted. If the deceleration is advanced, the overall transportation efficiency of the silicon wafer will decrease, resulting in waste. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is: in order to overcome the problem that there is no buffer mechanism when the silicon wafer reaches the designated position in the prior art and it cannot be quickly stopped and positioned, a conveying device for photovoltaic solar silicon wafers is provided.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a conveying device for photovoltaic solar silicon wafers, including a frame, a suction mechanism, a belt transmission mechanism and a buffer mechanism installed on the frame. The suction mechanism is located above the output end of the belt transmission mechanism, and the buffer mechanism is installed at the output end of the belt transmission mechanism. The belt transmission mechanism is used for transporting silicon wafers, and the buffer mechanism is used for abutting, buffering, decelerating and positioning the silicon wafers on the belt transmission mechanism. The buffer mechanism includes a cylinder and a buffer block. The piston rod of the cylinder is fixedly connected to the buffer block. Through the design of the cylinder and the buffer block, the rapid braking and positioning of the silicon wafer are realized, and the possible impact on the silicon wafer is prevented. While ensuring the transmission efficiency of the silicon wafer, the qualified rate of the silicon wafer is improved, and safe automated continuous production is achieved.
[0006] In order to solve the problem of silicon wafer transmission, further, the belt transmission mechanism includes a transmission belt, a driving roller, a tensioning roller, a first driven roller, a second driven roller and a motor. The driving roller, the tensioning roller, the first driven roller and the second driven roller are all rotatably installed on the frame. The transmission belt passes around the driving roller, the tensioning roller, the first driven roller and the second driven roller. The driving roller, the first driven roller and the second driven roller are located inside the space surrounded by the transmission belt, and the tensioning roller is located outside the space surrounded by the transmission belt. The output end of the motor is in transmission connection with the driving roller.
[0007] To solve the problem of the adjustment of the tensioning roller, it further includes an adjustment hole formed on the frame for the tensioning roller to move, so that the tensioning roller can adjust the tension of the conveyor belt, thereby increasing the service life.
[0008] To solve the problem of damage to the contact surface between the silicon wafer and the buffer block, it further includes a gasket provided on the buffer block, and the gasket can further protect the silicon wafer to prevent damage when it contacts the buffer block.
[0009] It further includes that the conveying device also includes a positioning mechanism for accurately positioning the silicon wafer. The positioning mechanism includes an adsorption seat and an air pump. The adsorption seat is fixedly connected to the buffer block. An air duct is formed in the adsorption seat. The input end of the air duct is located on the side of the adsorption seat close to the silicon wafer, and the output end of the air duct is connected to the input end of the air pump.
[0010] It further includes that the end face of the adsorption seat close to the silicon wafer is flush with the end face of the buffer block.
[0011] The beneficial effects of the present utility model are as follows: A photovoltaic solar silicon wafer conveying device provided by the present utility model realizes the rapid braking and positioning of the silicon wafer through the design of the cylinder and the buffer block, and prevents the possible impact on the silicon wafer. While ensuring the transmission efficiency of the silicon wafer, the qualification rate of the silicon wafer is improved, and safe automated continuous production is achieved.

[0018] The present utility model will now be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.
[0019] As Figure 1 is a schematic structural diagram of the present utility model, a photovoltaic solar silicon wafer conveying device, which includes a frame 1, a suction mechanism 2, a belt transmission mechanism 3 and a buffer mechanism 4 installed on the frame 1. The suction mechanism 2 is located above the output end of the belt transmission mechanism 3, and the buffer mechanism 4 is installed at the output end of the belt transmission mechanism 3. The belt transmission mechanism 3 is used for conveying silicon wafers. As Figure 2 shown, the buffer mechanism 4 is used for abutting, buffering, decelerating and positioning the silicon wafers on the belt transmission mechanism 3. The buffer mechanism 4 includes a cylinder 41 and a buffer block 42. The piston rod of the cylinder 41 is fixedly connected to the buffer block 42. The photovoltaic solar silicon wafer conveying device provided by the present utility model realizes the rapid braking and positioning of the silicon wafers through the design of the cylinder 41 and the buffer block 42, and prevents the possible impact on the silicon wafers, improves the qualified rate of the silicon wafers while ensuring the silicon wafer transmission efficiency, and enables safe automated continuous production.
[0020] The belt transmission mechanism 3 includes a transmission belt 31, a driving roller 32, a tensioning roller 33, a first driven roller 34, a second driven roller 35 and a motor 36. The driving roller 32, the tensioning roller 33, the first driven roller 34 and the second driven roller 35 are all rotatably installed on the frame 1. The transmission belt 31 is wound around the driving roller 32, the tensioning roller 33, the first driven roller 34 and the second driven roller 35. The driving roller 32, the first driven roller 34 and the second driven roller 35 are located inside the space surrounded by the transmission belt 31, and the tensioning roller 33 is located outside the space surrounded by the transmission belt 31. The output end of the motor 36 is in transmission connection with the driving roller 32.
[0021] As Figure 1 shown, an adjustment hole 11 for the tensioning roller 33 to move is provided on the frame 1, so that the tensioning roller 33 can adjust the tension of the transmission belt 31 to increase the service life.
[0022] A gasket 43 is provided on the buffer block 42, and the gasket 43 can further protect the silicon wafers and prevent damage when they contact the buffer block 42.
[0023] As Figure 3 、 Figure 4As shown in the figure, the conveying device further includes a positioning mechanism 5 for accurately positioning the silicon wafer. The positioning mechanism 5 includes an adsorption seat 51 and an air pump 52. The adsorption seat 51 is fixedly connected to the buffer block 42. An air passage 511 is provided in the adsorption seat 51. The input end of the air passage 511 is located on the side of the adsorption seat 51 close to the silicon wafer. The output end of the air passage 511 is connected to the input end of the air pump 52. By sucking air with the air pump 52 of the positioning mechanism 5, a negative pressure adsorption force is generated at the air passage 511 of the adsorption seat 51, so that the side end of the silicon wafer can be attached to the buffer block 42, further making the positioning of the silicon wafer accurate.
[0024] The end face of the adsorption seat 51 on the side close to the silicon wafer is flush with the end face of the buffer block 42.
[0025] During use, when the silicon wafer is placed on the belt transmission mechanism 3 and transported to its tail end, the silicon wafer contacts the gasket 43 on the buffer block 42. At this time, the buffer block 42 and the silicon wafer continue to move synchronously. Due to the air pressure in the cylinder, rapid deceleration braking of the silicon wafer is achieved and the silicon wafer is prevented from being damaged. During this process, by sucking air with the air pump 52 of the positioning mechanism 5, a negative pressure adsorption force is generated at the air passage 511 of the adsorption seat 51, so that the side end of the silicon wafer can be attached to the buffer block 42, further making the positioning of the silicon wafer accurate. After the braked silicon wafer is sucked and transferred away by the sucking mechanism 2, the cylinder 41 is inflated through the cylinder air pump to move the plug rod, thereby resetting the buffer block 42 to prepare for the next buffering.
[0026] Inspired by the above ideal embodiments according to the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
