In the future, industrial automation production scenarios vary greatly in geographical distribution and workshop environment. Various scenarios such as high-temperature heat treatment workshops, low-temperature cold chain warehousing, open-air processing stations, and constant-temperature precision workshops have huge environmental temperature spans, posing severe tests on the temperature-resistant operation capabilities of automation equipment.
Changes in ambient temperature will cause thermal expansion and contraction of metal parts and performance drift of electrical components, which directly affects the grasping and positioning accuracy of the electric gripper, long-term operation stability, and the service life of the entire machine.
The electric gripper, the core category of robot end effectors, must have stable operation capabilities in a wide temperature range in order to cover production scenarios in the entire industry.
In cold chain cold storage, winter open-air processing stations, high-temperature heat treatment forging workshops, closed high-temperature stamping workshops and other scenarios, extreme high and low temperature environments will cause multiple performance damage to conventional electric grippers.
In a low-temperature environment, the internal lubricating grease of the equipment solidifies, the sealing rubber parts harden, and the metal wire rod shrinks, causing the grabbing action to get stuck and the positioning accuracy to drop significantly. In a high-temperature environment, electrical components accelerate aging, seals soften and deform, and the body metal thermally deforms, causing problems such as servo signal failure, clamping reference drift, and workpiece loosening.
Ordinary electric grippers can only operate stably in normal and constant-temperature workshops, severely limiting the application of automated grabbing technology in cold chain, heat treatment, warehousing and other industries.
Worm’s electric gripper designed with a wide temperature range specifically solves the performance defects of various equipment caused by temperature changes and achieves stable grabbing operations in the entire temperature range.
Its exclusive structural design adapts to wide-temperature and full-range operation requirements.
The fuselage is made of special forged aluminum alloy with low thermal expansion coefficient. The metal deformation caused by temperature changes is extremely small, and the positioning error caused by temperature drift is controlled from the mechanical hardware level.
The seals of the whole machine are made of special fluorine rubber that is resistant to high and low temperatures. It remains flexible and elastic in low temperature environments and does not soften and deform in high temperature environments. It continues to maintain the dustproof and waterproof sealing performance of the whole machine.
The internal screw drive mechanism is filled with long-lasting and wide-temperature special lubricating grease. It will not solidify and agglomerate in sub-zero low temperature environments, ensuring smooth finger opening and closing movements throughout the process.
The whole machine has completed the high and low temperature stress relief heat treatment process before leaving the factory. There will be no deformation of the fuselage structure or loosening of internal parts under sudden temperature changes.
The fully sealed composite protective structure of the whole machine takes into account dust-proof, moisture-proof, and temperature isolation functions, and comprehensively protects the core components of the internal screw rod, sensor, and servo circuit board.
Standardized mechanical flanges and electrical communication interfaces have unified specifications, seamlessly connecting various finger claw accessories and mainstream industrial robots on the market. Changes in ambient temperature will not affect equipment installation standards and mechanical connection strength.
In the full temperature range environment, the whole machine has excellent all-weather operation stability.
The servo drive motor, control circuit board, stroke pressure sensor and other electrical components are all made from industrial wide-temperature original parts. The equipment starts and operates normally within a large temperature range. The servo current and grab signal output are continuously stable, and there are no low-temperature start-up jams or high-temperature servo runaway problems.
The servo drive has a built-in intelligent temperature adaptive algorithm, and the control system automatically adjusts the servo output parameters according to the real-time temperature of the environment to ensure that the clamping strength and opening and closing response speed of the entire machine are constant throughout the process.
The internal screw mechanical locking mechanism is not affected by changes in ambient temperature, and the grab connection is rigid and stable online throughout the entire process.
In scenarios such as robot handling of low-temperature cold chain materials, loading and unloading of machine tools in high-temperature heat treatment workshops, and precision assembly in workshops with temperature fluctuations, the entire machine has smooth grabbing movements, stable clamping conditions, and no screw rod jams or loose workpieces.
In addition, the built-in intelligent multi-point temperature compensation technology ensures stable positioning accuracy in the entire temperature range.
The fuselage has built-in multi-point high-precision temperature sensors to collect the temperature values of the fuselage and workshop environment in real time. The control system calculates the deformation error caused by thermal expansion and contraction of metal in real time and dynamically compensates for it.
Regardless of extreme working conditions of high and low temperatures, the repetitive positioning accuracy of the electric gripper is always stable at ±0.01mm, and there will be no clamping reference deviation due to fluctuations in ambient temperature.
Worm’s wide-temperature operation electric gripper technology relies on professional optimized structural design, all-weather operation stability, micron-level repeated positioning accuracy, long-term durability of the entire machine, and intelligent temperature compensation control system. It is natively adapted to mainstream industrial robots on the market. It is not afraid of high and low temperature environments in robot handling, machine tool loading and unloading, and precision assembly scenarios. It broadens the application boundaries of factory automation and promotes the automation upgrade of all manufacturing scenarios.
