Description

Technical Field

[0001] This invention belongs to the field of photovoltaic cell manufacturing equipment technology, and particularly relates to a support beam for quick assembly and disassembly of trays. Background Technology

[0002] On automated photovoltaic cell production lines, the cells are typically placed on dedicated carrier plates and supported by trays for the coating process. During high-precision manufacturing, the trays must be kept clean to avoid introducing particles or conductive impurities. After approximately 500 production cycles, the trays are removed from the frame, and the ITO film on the trays is cleaned off to meet cleanliness requirements.

[0003] Currently, the pallet is bolted to the carrier frame and to the support beams of the support itself. This method has the following disadvantages: 1. Low disassembly and assembly efficiency: Each replacement requires operators to manually tighten or loosen multiple screws, which is time-consuming and inefficient; 2. Poor automation compatibility: Manual operation interrupts the fully automated process of the production line, making it difficult to seamlessly integrate with robots, automatic gripping mechanisms, etc., and failing to achieve true "lights-out factory" style unmanned operation; 3. High precision requirements for equipment: To achieve automated disassembly and assembly of the original carrier plate assembly, the robotic arm needs to align the tray with the screw holes on the carrier plate with extremely high precision. This places stringent requirements on the positioning accuracy and cost of the equipment, and it has poor fault tolerance and is prone to interference or damage. 4. There are reliability risks: Screws may loosen under vibration, and manual operation may also lead to inadequate tightening due to negligence, which poses a safety hazard.

[0004] Therefore, the industry urgently needs a carrier plate assembly that can achieve rapid and accurate pallet positioning and locking without manual intervention or the use of tools, in order to improve the overall efficiency, reliability and intelligence level of automated production lines. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to overcome the shortcomings of the prior art and provide a support beam for quick assembly and disassembly of pallets.

[0007] A further improvement of the present invention is that a locking mechanism is provided at the mating position of the pallet and the frame. The locking mechanism is set on the frame and located around the pallet. The frame is provided with a front vertical beam and a rear vertical beam with side support beams. Multiple end face beams are connected between the front vertical beam and the rear vertical beam. The end face beams are connected to support beams. The pallet and the frame are positioned by a positioning mechanism.

Support beam blank one and support beam blank two are connected by pins.

[0010] A further improvement of the present invention is that the bottom of the support beam blank one is connected to the mounting bracket one, and the bottom of the support beam blank seven is connected to the mounting bracket two. The mounting bracket one and the mounting bracket two are fastened to the crossbeam support platform. The width of the support beam is ≤20mm and the height of the support beam is ≤20mm.

[0011] A further improvement of the present invention is that the locking mechanism includes a locking block, a locking pin and a side locking block, and the positioning mechanism includes a positioning pin disposed on the tray.

[0012] A further improvement of the present invention is that the guide structure includes a guide structure one and a guide structure two, the guide angle of the guide structure one and the guide structure two is between 60 degrees and 65 degrees, and the cross-sectional shape of the guide structure one and the guide structure two is trapezoidal, dovetail-shaped or T-shaped.

[0013] A further improvement of the present invention is that the front vertical beam and the rear vertical beam are connected by a tray baffle.

[0014] A further improvement of the present invention is that the end face beam includes an end face beam one, an end face beam two, and an intermediate beam, a support beam is disposed between the end face beam one and the intermediate beam, an intermediate support plate is connected between the intermediate beam and the front vertical beam, and a corner support plate is connected between the front vertical beam and the end face beam one, and the corner support plate has a waist-shaped hole.

[0015] A further improvement of the present invention is that the beam body of the supporting beam is made of a metal material, including stainless steel, titanium alloy, and aluminum.

[0016] Compared with the prior art, the present invention achieves at least the following beneficial effects: This invention provides a support beam that enables rapid, precise, and tool-free automated assembly and disassembly of pallets. The support beam guides the drooping carrier plate upwards, providing high load-bearing strength within a limited space and ensuring the flatness of the pallet on the carrier plate. This solves the problems of low assembly and disassembly efficiency, poor automation compatibility, and stringent requirements for equipment positioning accuracy caused by bolt fixing between the pallet and the support beam in existing technologies. No bolts are needed to lock the pallet and support beam; the guide structure achieves precise alignment and smooth separation of the pallet during assembly and disassembly, completely simplifying the locking and disassembly process. This allows the pallet to be used with automated equipment as well as for convenient and rapid manual assembly and disassembly, significantly improving the assembly efficiency of the pallet system and ensuring safety and reliability.
