Through the search of the prior art, the technical scheme similar to the patent is not searched.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide an in-process that goes on at the pressure equipment process, whether can accurately detect ventilative diaphragm in step and paste the flow sensor shell pressure equipment frock that targets in place, simple and feasible can realize ventilative diaphragm synchronous detection.
The above object of the present invention is achieved by the following technical solutions:
the utility model provides a can realize flow sensor shell pressure equipment device of ventilative diaphragm synchronous detection which characterized in that: including last mould of pressure equipment frock and pressure equipment frock lower mould, be provided with on pressure equipment frock lower mould and supply plastic housing and metal casing body male work piece installation cavity, its characterized in that: the device also comprises a photoelectric switch, a fixed column and a travel switch; the fixing column is installed below the upper die of the press fitting tool, the photoelectric switch is installed on the fixing column and arranged on the outer side of the installation cavity on the lower die of the press fitting tool, and the direction of a light beam emitted by the photoelectric switch corresponds to the position of a film on the plastic shell inserted into the installation cavity; travel switch fixed mounting is in the below of mould on the pressure equipment frock, and travel switch's stroke contact is adjusted well with the plastic casing who inserts the installation intracavity:
the alarm device is characterized by further comprising an alarm device, wherein the photoelectric switch, the travel switch, the alarm device and the power supply are sequentially connected in series to form an alarm control trigger circuit, and the photoelectric switch and the travel switch are both in a normally open state.
And moreover, the fixed column is cylindrical, the photoelectric switch is connected with the fixed column through the mounting seat, and the mounting seat is annularly sleeved on the fixed column and is fixedly connected with the fixed column through a bolt connected to one side.
The utility model has the advantages and positive effect:
adopt this pressure equipment frock, when the mould goes up down when carrying out the pressure equipment operation on the pressure equipment frock, photoelectric switch and travel switch drive down synchronous down on the pressure equipment frock, after travel contact and the plastics shell contact of travel switch, travel switch is closed, photoelectric switch gets into detection operating condition, it is down to continue along with the mould on the pressure equipment frock, photoelectric switch sends the aperture through the plastics shell of beam, if ventilative diaphragm has been installed, then photoelectric switch receives the reflected signal, photoelectric switch's normally open state does not change, the system does not report to the police, until accomplishing whole pressure equipment process: if the breathable membrane is not installed, the optical signal penetrates through the small hole, the photoelectric switch cannot receive the reflected signal, the photoelectric switch is closed, the alarm control trigger circuit is switched on, the system sends an alarm prompt, the upper die of the press-fitting tool stops descending, and press-fitting operation is interrupted, so that accurate detection of whether the breathable membrane is adhered to the correct position is achieved, and the breathable membrane adhesive tape has good feasibility.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
A flow sensor shell press-fitting device capable of realizing synchronous detection of breathable membranes is disclosed, please refer to FIGS. 1-4, and comprises a press-fitting tool upper die 1 and a press-fitting tool lower die 6, wherein a workpiece mounting cavity for inserting a plastic shell 4 and a metal shell 5 is arranged on the press-fitting tool lower die, and the invention point is as follows:
the device also comprises a photoelectric switch 7, a fixed column 3 and a travel switch 2. The fixed column is installed below the upper die of the press fitting tool, and the photoelectric switch is installed on the fixed column and arranged on the outer side of the installation cavity on the lower die of the press fitting tool. The direction of the light beam emitted by the photoelectric switch corresponds to the position of the film on the plastic shell inserted into the mounting cavity; the travel switch is fixedly installed below the die on the press-fitting tool, and a travel contact 2-1 of the travel switch is aligned with the plastic shell inserted into the installation cavity, so that the travel contact is in contact with the upper end of the plastic shell in the descending process of the die on the press-fitting tool, and the state of the travel switch is changed:
the alarm device is characterized by further comprising an alarm device 9, wherein the photoelectric switch, the travel switch, the alarm device and the power supply are sequentially connected in series to form an alarm control trigger circuit, and the photoelectric switch and the travel switch are in a normally open state.
In the above structure, the optoelectronic switch is preferably mounted on the fixing column as follows:
the fixing column is cylindrical, the photoelectric switch is connected with the fixing column through the mounting seat, and the mounting seat is annularly sleeved on the fixing column and is fixedly connected with the fixing column through a bolt connected to one side. The photoelectric switch can be conveniently adjusted to the position capable of accurately capturing the small holes of the breathable membrane and the plastic shell by adopting the installation mode, and has the advantage of convenience in installation and alignment.
In the press mounting device, in the process of pressing the plastic shell into the metal shell, the photoelectric switch is used for detecting whether the breathable membrane 8 is adhered to the position of the small hole 4-1 on the upper part of the plastic shell or not, and under the condition that the breathable membrane is installed, the photoelectric switch receives a reflected signal and the system does not give an alarm; when the breathable membrane is not installed, the optical signal passes through the small hole, the photoelectric switch cannot receive the reflected signal, and under the action of the position switch, the system gives an alarm to prompt, so that whether the breathable membrane is installed in place is accurately detected.
