A kind of mechanical arm with bleeder sucker and its method of work for installing spring
Technical field
The present invention relates to the technical field of mechanical arm, more particularly to a kind of machine with bleeder sucker for installing spring
Tool arm.
Background technology
Because the installation environment of spring is complex, being changed mounting means, at present, the installation of spring is generally manual peace more
Dress, still, when spring need to be arranged on inside machine, human hand is inconvenient to probe into, and is difficult observation, even if utilizing when mounted
Viewfinder, is also very influence production efficiency, and installation quality is difficult guarantee;In addition, when the required spring-loaded spring of peace
When power is very big, manual operations is more difficult, and this requires a kind of spring installation system of automation, to replace manual operations,
And the complicated installation environment of spring can be tackled.
Other spring, which is installed, may produce unqualified, or spring force is not reaching to standard after installing, and this is accomplished by
Effectively detected after installation, but common position detection is qualified not to ensure that spring force necessarily reaches standard.
The content of the invention
The purpose of invention:The present invention discloses a kind of mechanical arm with bleeder sucker for installing spring, instead of craft
Spring is installed, production efficiency is greatly improved, the problem of bad installation of machine contained spring can be solved, it is possible to the complicated reality of reply
Border situation;After installation, directly spring force is detected, once detecting to install unqualified, installed again automatically.
Technical scheme:In order to realize the above object the invention discloses it is a kind of install spring with bleeder sucker
Mechanical arm, including pedestal, mechanical arm, manipulator, drive device, control device and position detecting device, pedestal is provided with report
Alarm device;The manipulator includes two spring clamping jaws, a bleeder sucker and detection pawl, and wherein bleeder sucker is set
Between two spring clamping jaws, each spring clamping jaw includes two crawl fingers, and detection pawl end is provided with force cell;Institute
Mechanical arm, spring clamping jaw and crawl finger, bleeder sucker and the detection pawl stated are connected with drive device, force cell,
Warning device, position detecting device and drive device are connected with control device.This design use can replace installing bullet by hand
Spring, greatly improves production efficiency, the problem of solving the bad installation of machine contained spring, it is possible to the complicated actual feelings of reply
Condition;Installation site is determined by position detecting device, after installation, spring force detected, once detect to install not
It is qualified, installed again automatically;When unqualified state can not be excluded, warning device is alarmed.
Further, a kind of above-mentioned mechanical arm with bleeder sucker for installing spring, the drive device includes
Vacuum suction blower fan, it is connected with bleeder sucker.This design can inhale for being magnetic and not having magnetic object
Draw, applicability is wide.
Further, above-mentioned a kind of mechanical arm with bleeder sucker for installing spring, the force cell is
Pressure sensor.This design is by the spring force of detection spring, and to differentiate whether spring is properly installed, this mode is direct
And effectively.
Further, a kind of above-mentioned mechanical arm with bleeder sucker for installing spring, the end of the crawl finger
Portion is provided with rubber sleeve.Rigid contact when capturing spring is converted into flexible contact by this design, prevents from damaging capturing spring.
Further, above-mentioned a kind of mechanical arm with bleeder sucker for installing spring, the rubber sleeve surface is set
There are anti-slip veins.This design improves the frictional force between rubber sleeve and spring, prevents from slipping.
Further, a kind of above-mentioned mechanical arm with bleeder sucker for installing spring, described two spring clamping jaws
Can drive device effect under mutually with parastate closer or far from.
Further, a kind of above-mentioned mechanical arm with bleeder sucker for installing spring, described two spring clamping jaws
One end is connected, and folding can be carried out by fulcrum of tie point under drive device effect.
A kind of method of work for the mechanical arm with bleeder sucker for installing spring, specific works method is as follows:1)
Mechanical arm starts action, and driving mechanical hand reaches spring storeroom, and bleeder sucker attracts spring;2)Mechanical arm driving mechanical hand
Spring storeroom is left, installation site is prepared to enter into, while spring clamping jaw fixes both ends of the spring respectively;3)Spring clamping jaw is by bullet
Spring stretches or is compressed to setting length, while mechanical arm driving mechanical hand reaches predetermined installation site;4)One of spring
Spring one end is first attached to specified location by clamping jaw;5)The spring other end is attached to specified location by another spring clamping jaw again,
During this, another spring clamping jaw can be compressed or stretch to spring under drive device drive, that is, adjust spring
Length is so as to smoothly installation;6)After the completion of once mounting, bleeder sucker stops attracting;7)Detect that pawl drives force cell pair
Spring after installation is detected, if spring force reaches setting value, illustrates that spring is installed successfully, and manipulator is exited and carried out next
Wheel is installed;8)If spring force does not reach setting value, illustrate spring install failure, bleeder sucker is engaged with spring clamping jaw, taken
Go out spring and installed again;9)If continuous 2 ~ 5 times can not install, warning device is alarmed, and event is excluded by operating personnel
Barrier.
Further, a kind of method of work of above-mentioned mechanical arm with bleeder sucker for installing spring, the bullet
When spring is compression spring, two spring clamping jaws are directly clamped and compression spring, are now captured finger and are in closed configuration;Spring is
During extension spring, crawl finger is opened, and the hook at crawl extension spring two ends and clamping are stretched with this;Spring is torsion
During spring, crawl finger is opened, and the two-arm of torque spring is captured and clamp, to be installed.
Above-mentioned technical proposal can be seen that the present invention and have the advantages that:A kind of installation spring of the present invention
Mechanical arm with bleeder sucker, instead of installing spring by hand, greatly improves production efficiency, and solve inside machine
The problem of spring bad installation;All springs can be drawn, are more convenient while capturing spring, and avoid damaging spring, were installed
Journey is more reliable, and can tackle the actual conditions of complexity, while meeting the installation of compression spring, extension spring and torque spring;Peace
After dress, spring force is detected by pressure sensor, once detecting to install unqualified, control device sends instruction, from
It is dynamic to be installed again;It is unqualified to be alarmed when can not exclude automatically, it is more humane.
