Clean explosion-proof crane for semiconductor manufacturing

1. Product Core Positioning and Design Criteria

ZJJB clean explosion-proof overhead travelling crane is the core positioning for overseas high-end precision manufacturing scenes to provide “explosion-proof safety + dust-free clean” integrated lifting and hoisting solutions, the design standards strictly follow the GB3836 series of explosion-proof safety standards, general standards for cleanroom operations, for semiconductor manufacturing, chemical precision synthesis, etc. Both the risk of flammable and explosive, but also the risk of dust accumulation, and also the core benchmark products in the field of high-end cleanliness.

There are flammable and explosive risks, but also for the workshop dust control has stringent requirements of the scene tailored to solve the traditional explosion-proof cranes easy to produce dust, dust accumulation, can not be adapted to the clean room operation of the industry’s pain points.

2. Core structural design

The entire structure of the machine is designed around the three core requirements of clean dust, explosion-proof and fireproof flower, frequency stable operation, high precision modular assembly structure, the core is composed of three key parts, the structure of the cooperative realization of high-precision hazardous scenes of safety, clean and efficient lifting:

2.1 Clean protection structure: the whole machine adopts high-pressure anti-static spraying process, forming a dense protective layer on the surface, with non-stick dust, non-dust-producing characteristics; the body, transmission components and connection gaps are made fully closed sealing treatment, to avoid accumulation of dust at source; hooks, wheels and other parts in direct contact with the material are made of stainless steel and do the passivation of the surface treatment, corrosion-free, no debris, and the abrasion parts are equipped with non-corrosive material and dust Wear parts are equipped with non-corrosive materials and dust collection devices to completely eliminate the equipment itself from producing dust and accumulating dust.

2.2 Explosion-proof safety mechanism: the electrical system is designed according to the explosion-proof standard, and the motors, controllers, cables and so on are all explosion-proof special models, and the cables are laid with explosion-proof casing; all the mechanical moving parts are treated with anti-static and spark suppression, eliminating the hidden danger of friction and collision-generated sparks, and realizing the explosion-proof safety from the double dimension of electric and mechanical, which is suitable for gas and dust flammable and explosive environments.

2.3 Frequency conversion drive control mechanism: the whole machine is equipped with frequency conversion control technology, the lifting and running mechanism realizes stepless speed regulation, stable running speed, no impact of starting and stopping, which greatly reduces the failure rate of the equipment and improves the precision of lifting and operating efficiency; the frequency conversion system adopts energy-saving design, which effectively reduces energy consumption while meeting the high precision operation, and meets the energy-saving demand of overseas high-end manufacturing enterprises.

3. Core product advantages (meet the needs of overseas high-end precision work, different from traditional explosion-proof equipment)

As a semiconductor explosion-proof crane specially designed for high-precision clean explosion-proof scenarios, its core advantages revolve around clean dust, double explosion-proof safety, frequency stability and high efficiency, high-precision adaptations to start, perfectly suited to overseas semiconductors, high-end chemical and other customer operations and procurement pain points, but also the core highlights of the difference between the traditional explosion-proof overhead travelling crane:

3.1 Full-dimensional clean design, adapt to the strict requirements of clean room: high-voltage anti-static spraying + fully enclosed sealing structure, to achieve the equipment does not stick to the dust, dust production, stainless steel passivation parts + dust collection device, to completely avoid the equipment on the clean environment of the workshop pollution, fully meet the semiconductor manufacturing, chemical precision workshop dust control requirements, without additional equipment to do clean transformation, can be directly stationed in the clean room operations.

3.2 Mechanical + electrical double explosion-proof, safety protection without dead ends: mechanical parts of the anti-static spark suppression, eliminating friction sparks from the source; electrical system full explosion-proof design, to eliminate electrical sparks, two-dimensional explosion-proof design not only to meet the requirements of the safe operation of flammable and explosive environments, but also to adapt to the high precision scene of the low-fault demand, equipment operation safety and reliability far more than the traditional explosion-proof cranes.

3.3 Frequency control technology, low failure and high precision and efficiency: variable frequency stepless speed control allows equipment to run at a stable speed, start and stop without impact, lifting positioning accuracy is higher, suitable for semiconductor wafers, precision chemical raw materials and other high-end materials lifting needs; at the same time, the frequency conversion technology significantly reduces the mechanical wear and tear of equipment, machine failure rate is significantly reduced, reducing equipment downtime for maintenance to enhance the overall efficiency of the workshop operations.

3.4 High-precision material selection, corrosion-resistant and long life: food-grade / industrial-grade stainless steel manufacturing and passivation treatment of material contact parts, wear parts of the selection of non-corrosive special materials, with excellent corrosion resistance, anti-debris characteristics, to adapt to the corrosive environment of the high-end chemical workshop, the service life of the equipment compared with the traditional explosion-proof cranes to enhance the 30% or more, reducing long-term cost of use.
