Description

Technical Field

[0001] The utility model relates to a transport trolley, in particular to a PCB board transfer trolley which is anti-fall and anti-collision. Background Art

[0002] PCB board transfer trolley, also known as anti-static turnover trolley or transfer trolley, is commonly used in electronic manufacturing and circuit board production lines and is widely used.

[0003] At present, when the existing PCB board transfer trolley is in use, the PCB board is usually positioned and placed by the slot plates or limit grooves arranged at intervals on the trolley. The structure is relatively simple and does not have the structural function of preventing falling and collision. Therefore, in the actual transportation process, when some special circumstances occur and the emergency stop is required, the center of gravity of the transfer trolley is easily unstable due to the effect of inertia, resulting in tipping and overturning, which will cause the board to slide sideways or fall and be damaged; and when the transfer trolley collides during the transportation process, it is easy to cause the PCB board placed in the slot plate or the limit groove to be bumped, which can easily lead to product quality problems of the PCB board.

[0004] In view of this, a PCB board transfer trolley with anti-fall and anti-collision is proposed to solve the above technical problems. Utility Model Content

[0007] As a further improvement of the above solution, the barrier is mainly composed of a steel ring and a plastic ring that can be telescopically folded and connected in series, and the steel rings are distributed at intervals along the plastic ring.

[0008] As a further improvement of the above scheme, the positioning assembly includes a guide sleeve, a support rod, a blocking block, a spring, a knob and a top block.
