Technical Field
[0001] This utility model belongs to the field of photovoltaic crystal rod processing technology, and relates to a crystal rod centering mechanism. Background Technology
[0002] In the photovoltaic industry, due to process requirements, it is often necessary to inspect and record the dimensions of crystal rods of different lengths to prepare for subsequent processes. The crystal rods must first be fixed and aligned to facilitate manual or robotic operations. However, existing alignment mechanisms are complex and cumbersome, and the overall structure is unstable, often shaking during alignment, affecting accuracy, resulting in high production costs, and they cannot achieve online alignment of crystal rods. Summary of the Invention
[0003] In order to overcome the shortcomings of the prior art, this utility model provides a crystal rod centering mechanism. This centering mechanism can be directly set above the conveyor line. The centering mechanism has a simple structure and only requires one centering cylinder, which can meet the requirements and reduce costs. The two centering frames are set in a staggered manner, which makes the centering stable and does not shake, resulting in high centering accuracy.
[0004] The above-mentioned objective of this utility model is achieved through the following technical solution:
[0005] A crystal rod centering mechanism includes a centering beam, with a centering frame on each side of the beam. The centering frames are slidably connected to the top surface of the beam via a centering guide rail and a centering slider. A centering cylinder is mounted on the top surface of the beam, and both ends of the cylinder are connected to the frame via cylinder connectors. A centering gripper connector is mounted at the bottom of each frame, with a gripper on the inner side of the connector.
[0006] Two centering frames are positioned horizontally and offset from each other. The cylinder rod of the centering cylinder is connected to the centering cylinder connector. The centering jaws are mounted on the centering jaw connector using T-nuts.
[0007] The centering cylinder drives the centering frame to move along the centering guide rail via a telescopic cylinder rod, thereby pushing the centering gripper connector and the centering gripper. The left and right centering grippers push the crystal rod in two directions, aligning the crystal rod in the width direction.
[0008] Furthermore, four sets of centering guide rails and centering sliders are provided. Each centering frame has a U-shaped plate structure on its top surface. Each side of the U-shaped plate is slidably connected to the centering crossbeam through a set of centering guide rails and centering sliders.
[0009] Furthermore, the centering guide rail is mounted on the top surface of the centering crossbeam. The centering slider is mounted on the centering frame.
[0010] Furthermore, the centering cylinder is positioned on the centerline of the centering crossbeam. Its distance from the two centering frames is the same.
[0011] Furthermore, the mechanism is also equipped with a PLC control system. The centering cylinder is connected to the PLC control system, and there is no limitation on a specific model, as long as it can realize its working function.
[0012] The centering mechanism can be installed above the conveyor line using a support frame.
[0013] The advantages of this utility model compared with the prior art are:
[0014] The crystal rod alignment mechanism provided by this utility model can be directly set above the conveyor line. The alignment mechanism has a simple structure and only requires one alignment cylinder, which can reduce costs. The two alignment frames are set in a staggered manner, which makes the alignment stable, does not shake, and has high alignment accuracy. Attached Figure Description

[0018] The present invention is described in detail below through specific embodiments, but this does not limit the scope of protection of the present invention. Unless otherwise specified, the experimental methods used in the present invention are all conventional methods, and the experimental equipment, materials, reagents, etc. used can all be obtained commercially. Example
[0019] A crystal rod centering mechanism, such as Figure 1-2 As shown, it includes a centering beam 6, with a centering frame 1 on each side of the centering beam 6. The centering frame 1 and the top surface of the centering beam 6 are slidably connected by a centering guide rail 2 and a centering slider 3. A centering cylinder 5 is set on the top surface of the centering beam 6. The two ends of the centering cylinder 5 are connected to the centering frame 1 by a centering cylinder connector 4. A centering gripper connector 7 is set at the bottom of each centering frame 1, and a centering gripper 8 is set on the inner side of the centering gripper connector 7.
[0020] Two centering frames 1 are positioned left and right, and are staggered. The cylinder rod of the centering cylinder 5 is connected to the centering cylinder connector 4. The centering gripper 8 is installed on the centering gripper connector 7 by a T-nut.
[0021] The centering cylinder 5 drives the centering frame 1 to move along the centering guide rail 2 via a telescopic cylinder rod, thereby pushing the centering gripper connector 7 and the centering gripper 8. The left and right centering grippers 8 push the crystal rod 6 in two directions, so that the crystal rod 6 is centered in the width direction.
[0022] Four sets of centering guide rails 2 and centering sliders 3 are provided. Each centering frame 1 has a U-shaped plate structure on its top surface. Each side of the U-shaped plate is slidably connected to the centering beam 6 through a set of centering guide rails 2 and centering sliders 3.
[0023] The centering guide rail 2 is mounted on the top surface of the centering crossbeam 6. The centering slider 3 is mounted on the centering frame 1.
[0024] The centering cylinder 5 is positioned on the center line of the centering crossbeam 6. It is equidistant from the two centering frames 1.
[0025] The mechanism is also equipped with a PLC control system. The centering cylinder 5 is connected to the PLC control system, and there is no limitation on a specific model, as long as it can realize its working function.
[0026] The crystal ingot alignment mechanism can be implemented by setting it above the conveyor line using a bracket. The crystal ingot alignment mechanism is mounted on the bracket, positioned entirely above the conveyor line, which is not specially restricted. A photoelectric switch is installed on the conveyor line to detect the crystal ingot's arrival and sends a signal back to the alignment mechanism, which is then in the open state. The crystal ingot enters the alignment mechanism. First, the crystal ingot is conveyed in by the canvas conveyor line, triggering the photoelectric switch on the canvas conveyor line. The PLC control system then triggers the canvas conveyor to stop, and the crystal ingot is no longer being conveyed. The alignment cylinder 5, by retracting its cylinder rod, moves the alignment frame 1 along the alignment guide rail 2, thereby pushing the alignment gripper connector 7 and the alignment gripper 8. The two alignment grippers 8 clamp the crystal ingot in two directions, aligning it in the width direction. After other checks are completed, in the crystal ingot alignment mechanism, the alignment cylinder 5, by extending its cylinder rod, moves the alignment frame 1 along the alignment guide rail 2, thereby pushing the alignment gripper connector 7 and the alignment gripper 8. The two centering jaws 8 move away from the crystal rod in two directions, releasing the crystal rod. Finally, the crystal rod is conveyed out of the conveyor line 7 by the canvas belt conveyor. The entire operation is now complete.
[0027] The embodiments described above are merely preferred embodiments of this utility model, and not all feasible embodiments of this utility model. For those skilled in the art, any obvious modifications made without departing from the principles and spirit of this utility model should be considered to be included within the scope of protection of the claims of this utility model.
