Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of silicon wafer transportation, in particular to a silicon wafer transport trolley. Background Art
[0002] In the photovoltaic industry, in the field of single and multi-crystalline silicon ingot slicing, after the silicon ingot is sliced by the slicer, it is unloaded by the unloading trolley to put the silicon wafers in the slicer with the crystal tray on the transport trolley, and then manually transported to the back-end debonding and inserting link. After reaching the subsequent link, the upper part of the trolley is hoisted into the workstation by the hoisting machinery for debonding and subsequent processes. The basic characteristics of a qualified transport trolley are to ensure convenient and fast unloading, safe and stable transportation, and no violent shaking that causes silicon wafer loss.
[0003] The existing silicon wafer transfer carts are as follows:
[0004] When unloading, the electric forklift arm on the trolley is used to slowly descend, and two support rods are installed in the reserved holes of the crystal tray. The silicon wafer slowly falls and the position is adjusted front and back. The support rods contact the supporting points on both sides of the material transport trolley and slowly apply force. Finally, the silicon wafer is placed on the material transport trolley. There are foam tubes on both sides of the material transport trolley to limit the position and protect the silicon wafer. The foam tubes are pulled by rubber bands to ensure that the silicon wafer will not shake. It is then manually transported to the next process.
[0005] Today's material transport carts have a small support point area, so they need to frequently adjust their front and rear positions when unloading materials, which is inconvenient to operate and wastes time. In addition, there is no fixation between the support rod and the support point, relying purely on friction. They are prone to sliding during transportation, causing the silicon wafers to shake and cause losses. The foam tubes that fix the sides of the silicon wafers also do not firmly fix the silicon wafers. During manual transportation, changes in speed or foreign objects on the road can easily cause the silicon wafers to shake and collide, resulting in wafer drop and breakage during transportation. Summary of the invention
[0006] The technical problem to be solved by the utility model is that it takes time for the existing material transport trolley to adjust the support position, resulting in low efficiency and poor clamping stability for silicon wafers.
[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is: a silicon wafer transfer trolley, including a base frame with supporting rollers at the bottom, a support frame fixed to the top of the base frame and round rod limiting structures fixed on both sides of the support frame, the round rod limiting structures are symmetrically distributed on both sides of the support frame, and flexible silicon wafer clamping assemblies are arranged on the relatively inner sides of the support frame, and the two silicon wafer clamping assemblies can move relative to each other.
[0008] Preferably, the silicon wafer clamping assembly includes adjusting screws distributed at both ends of the same side of the support frame, the adjusting screws are threadedly connected to the support frame, and one end of the two adjusting screws located in the support frame is connected by a rubber belt, the rubber belt is rotatably connected to the adjusting screw, and a rubber belt axial movement limiting structure is fixedly arranged on the adjusting screw.
[0009] Preferably, the limiting structure is a limiting seat fixedly arranged at the end of the adjusting screw, the limiting seat is cylindrical, an annular groove is arranged in the middle of the outer peripheral surface of the limiting seat, and the rubber belt is located in the annular groove.
[0010] Preferably, one end of the adjusting screw located on the outside of the supporting frame is vertically fixedly connected with a handle.
[0011] Preferably, the round rod limiting structure is a V-shaped groove fixedly arranged on the top of the support frame, and the V-shaped grooves are arranged in pairs and are respectively located on both sides of the support frame.
[0012] 1. The utility model provides a silicon wafer transfer trolley, which adds a cylindrical limiting structure on the top of the support frame, places a support rod passing through the silicon wafer crystal tray on the cylindrical limiting structure, limits the movement of the support rod through the cylindrical limiting structure, and enables the support rod to automatically slide into the cylindrical limiting structure, thereby improving the placement efficiency of the silicon wafer.
[0013] 2. By arranging a silicon wafer clamping assembly on the relatively inner side of the support frame, the flexible silicon wafer clamping assembly can effectively clamp the two ends of the silicon wafer on the support plate, which can serve as an anti-collision cushion to prevent the silicon wafer from being damaged by collision due to shaking, and can also limit the shaking of the silicon wafer, thereby improving the safety of the silicon wafer transportation process.

[0018] like Figure 1 and Figure 2As shown, the utility model provides a silicon wafer transfer trolley, including a base frame 1 with supporting rollers at the bottom, a support frame 2 fixed to the top of the base frame 1 and round rod limiting structures fixedly arranged on both sides of the support frame 2, the round rod limiting structures are symmetrically distributed on both sides of the support frame 2, and flexible silicon wafer clamping assemblies are arranged on the relatively inner sides of the support frame 2, and the two silicon wafer clamping assemblies can move relative to each other.
[0019] Move the material transport cart to the silicon wafer unloading place. The silicon wafer is fixedly connected to the crystal tray, which is provided with an opening. After the support rod passes through the silicon wafer crystal tray, the two ends of the support rod are respectively placed on the corresponding round rod limiting structures on both sides of the support frame 2, so that the support rod rolls to the lowest end of the round rod limiting structure, realizing the rolling limit and effective support of the support rod. Then, by moving the flexible silicon wafer clamping assembly located on both inner sides of the support frame 2, the silicon wafer clamping assembly moves toward the silicon wafer, and the two ends of the silicon wafer are clamped, and the silicon wafer can be transported.
[0020] like Figure 1 and Figure 2 The silicon wafer clamping assembly includes adjusting screws 4 distributed at both ends of the same side of the support frame 2, the adjusting screws 4 are threadedly connected to the support frame 2, one end of the two adjusting screws 4 located in the support frame 2 is connected by a rubber belt 6, the rubber belt 6 is rotatably connected to the adjusting screws 4, and an axial movement limiting structure of the rubber belt 6 is fixedly provided on the adjusting screw 4.
[0021] The adjusting screw 4 passes through one side of the support frame 2. When clamping the silicon wafer, the two adjusting screws 4 on the same side of the support frame 2 are rotated. The adjusting screw 4 pushes the rubber belt 6 toward the silicon wafer during the rotation. After contacting the silicon wafer, the rubber belt 6 is tightened and fully contacts one end of the silicon wafer; after the rubber belts 6 on both sides of the support frame 2 are moved into place, the silicon wafer is tightly clamped.
[0022] like Figure 1 As shown, in order to prevent the rubber belt 6 from falling off or shifting from the adjusting screw 4, resulting in the inability to tightly clamp the silicon wafer. The limiting structure is a limiting seat 5 fixedly arranged at the end of the adjusting screw 4, the limiting seat 5 is cylindrical, and an annular groove is arranged in the middle of the outer circumference of the limiting seat 5, and the rubber belt 6 is located in the annular groove. By arranging the limiting seat 5 at the end of the adjusting screw 4, the connecting end of the limiting seat 5 and the adjusting screw 4 is a circular boss, and the other end is threadedly connected to a disc. After the rubber belt 6 is inserted into the protrusion in the center of the boss, the disc is threadedly connected to the boss, forming a cylindrical limiting seat 5 structure with an annular groove in the middle.
[0023] like Figure 1 and Figure 2 As shown, it is convenient for the staff to rotate the adjusting screw 4. One end of the adjusting screw 4 located outside the support frame 2 is vertically fixedly connected with a handle 7.
[0024] like Figure 1 and Figure 2 The round rod limiting structure is a V-shaped groove 3 fixedly arranged on the top of the support frame 2, and the V-shaped grooves 3 are arranged in pairs and are respectively located on both sides of the support frame 2. The width of the V-shaped groove 3 is increased, so that when placing the support rod, the support rod can be easily placed in the groove of the V-shaped groove 3, and then the support rod falls into the groove bottom of the V-shaped groove 3 by rolling the support rod.
