Technical field
This utility model belongs to technical field of medical treatment mechanical, and relating to is a kind of plug assembly of medical apparatus and instruments.
Background technology
In the medical apparatus and instruments assembling process, often two different parts need be pegged graft.At present, owing to there is not corresponding device thereof to carry out plug connector and the assembling that is subjected to fitting automatically, all adopt manual operations to operate.Because the sanitary condition of medical apparatus and instruments is strict, generally speaking, manual pegging graft all is to carry out in aseptic cleaning shop.
Manual shortcoming is: 1. can and produced by fitting to plug connector unavoidably in assembling process and pollute, make it adhere to pathogenic bacteria, cause the contamination of products risk to increase.2. manual assembling speed is low, and work efficiency is low, is difficult to adapt to the intense market competition needs.3. aseptic cleaning shop need take bigger space, in addition workers'health, work clothes, regular maintenance is also all had very high requirement, makes production cost increase.
In order to increase work efficiency, reduce the pollution of medical machinery product, people have designed various automatic assemblings, but the apparatus for assembling of these medical apparatus and instruments can not be applicable to plug connector and the assembling that is subjected to fitting.
Summary of the invention
The purpose of this utility model is at the plug connector of medical apparatus and instruments and is subjected to the grafting of fitting to have above-mentioned problem, a kind of simple in structure, safety and sanitation, efficient height is provided, can realizes the plug assembly of the medical apparatus and instruments that connects automatically.
The purpose of this utility model can realize by following technical proposal: a kind of plug assembly of medical apparatus and instruments, be arranged on and be used for fixing the rotating disk station that is subjected to fitting and be used to carry between the delivery track of plug connector, it comprises support and the rotating shaft that is horizontally set on the support, it is characterized in that, in rotating shaft, be fixed with a swinging block, on swinging block, be provided with the mechanical hand that at least one is used to grasp plug connector, be provided with between mechanical hand and the swinging block be fixed on swinging block on be used for the telescoping mechanism that promotion robot moves.
The plug assembly of this medical apparatus and instruments is to be used for plug connector is plugged into the device that is subjected on the fitting.In this device, the swinging block that is connected in the rotating shaft can be swung between rotating disk station and delivery track, and the amplitude of its swing is according to the decision of the height of the track at plug connector place and rotating disk station.Under the general situation, require when swinging block is put horizontal level, can reach the requirement of the central lines that is subjected to fitting and plug connector, when putting on the vertical direction, swinging block can grasp plug connector, the direction that helps grasping plug connector like this and no longer need to adjust plug connector, in addition telescoping mechanism also smoothly promotion robot towards rotating disk station direction.
After mechanical hand grasped plug connector, plug connector upwards promoted earlier plug connector, and swinging block drives the plug connector swing then.When the center of plug connector string pendulum to when being subjected to the central lines of fitting, under the effect of telescoping mechanism, promotion robot is subjected on the fitting to moved by fitting plug connector is plugged on.At this moment, under the effect of telescoping mechanism, mechanical hand is inserted into the plug connector that grasps and is subjected in the fitting, and mechanical hand resets then, and swinging block resets, and waits for the circulation of next time pegging graft.
In the plug assembly of above-mentioned medical apparatus and instruments, described telescoping mechanism is a telescopic cylinder that is fixed on the swinging block, and the piston rod and the mechanical hand of telescopic cylinder are connected.Mechanical hand is realized elasticly being subjected to purpose on the fitting to reach plug connector is plugged under the effect of telescopic cylinder.
In the plug assembly of above-mentioned medical apparatus and instruments, described mechanical hand comprises a clamp that clamps cylinder and two interlocks, and the piston rod and the clamp that clamp cylinder link.Under the effect that clamps cylinder, two clamps are drawn close mutually to realize clamping purpose.It is multiple that two clamps realize that the interlock mode can have, and for example, by gears engaged, just can drive another clamp on a clamp time and move simultaneously when clamping cylinder action between two clamps, realizes clamping or unclamp.
In the plug assembly of above-mentioned medical apparatus and instruments, the motor shaft of described rotating shaft and swing motor links and can drive mechanical hand swing on the swinging block.Swinging block is connected in the rotating shaft, is power with the swing motor.Be noted that the swing motor here is connected with control circuit, under the control of control circuit, the swing motor can allow swinging block swing back and forth.
In the plug assembly of above-mentioned medical apparatus and instruments, described swing motor is spacing motor, and the mechanical hand that this swing motor can drive on the swinging block is vertically switching between state and the level.Use spacing motor the angle of swinging block can be controlled in 90 degree, can better control mechanical hand and vertically switch between state and the level.
In the plug assembly of above-mentioned medical apparatus and instruments, described swinging block is provided with 2~8 mechanical hands that are used to grasp plug connector, and each mechanical hand links with a telescopic cylinder respectively.A plurality of mechanical hands are worked simultaneously, have improved the efficient of pegging graft.
In the plug assembly of above-mentioned medical apparatus and instruments, be provided with a buffer unit between described support and the swinging block, described buffer unit comprises that level is located in the buffer bar on the support, is with spring on buffer bar, one end of spring acts on the buffer bar, and the other end acts on the support; On swinging block, be provided with the block that can be pressed on the buffer bar end.Be used to cushion swinging block and switch to the rigid impact of vertical state from level, and the noise when reducing work.
Compared with prior art, the advantage that originally has the plug assembly of following medical apparatus and instruments:
1, the plug assembly of this medical apparatus and instruments is fixed with a swinging block in rotating shaft, is provided with mechanical hand on swinging block, is provided with promotion robot towards the elastic telescoping mechanism of rotating disk station direction between mechanical hand and swinging block.Plug connector is plugged into replaced manually by machinery by the work of fitting, improved the efficient of producing, reduced cost.
2, because machinery has replaced manually, the health that gets product is guaranteed, and makes patient avoid infection in use, has improved safety.
