Description

A pen-type suction fixture

technical field

The utility model relates to the technical field of pneumatic tools, in particular to a pen-type suction jig.

Background technique

At present, the more common pen-type suction fixture is actually a vacuum suction pen, which is a small pneumatic tool that looks like a pen, and can absorb thin film or small granular products for bonding or assembly, etc. .

But when absorbing plastic film products such as PET, still have certain defect, because the film product such as PET has very big static electricity, when suction disappears, film is not easy to come off.

Utility model content

The technical problem to be solved by the utility model is to provide a pen-type suction jig, which can not only absorb thin film or small granular products, but also effectively solve the problem that static electricity products are not easy to fall off. question.

The technical solution of the utility model is to provide a pen-type air suction fixture, including a pen body, a vacuum generator for vacuuming the pen body, a solenoid valve connected with an external air source, and an adsorption device for controlling whether to perform the adsorption action. The control switch, the electromagnetic valve is electrically connected with the adsorption control switch, and also includes a throttle valve, and the vacuum generator and the throttle valve are connected in parallel between the air inlet end of the pen body and the air outlet end of the electromagnetic valve.

The pen body includes a nib for picking and placing the product, and a pen container for carrying the nib. The nib and the pen container are combined to form the pen body. The nib can be designed independently to adapt to different shapes and types of products to be sucked.

The adsorption control switch is installed on the wall body of the pen body to facilitate the operation of the adsorption control switch.

The solenoid valve is a three-way solenoid valve, the intake end of the three-way solenoid valve is connected to an external air source through a gas pipe, and the two gas outlet ends of the three-way solenoid valve are respectively connected to a throttle valve and a vacuum generator through a gas pipe. The three-way solenoid valve is the preferred solenoid valve, which can satisfy the connection of the throttle valve, the vacuum generator and the external air source under the state of setting up a solenoid valve, so that the overall structure becomes simple and compact.

A three-way joint is provided between the air inlet end of the pen body and the throttle valve and the outlet end of the vacuum generator to realize communication and connection. The three-way joint can facilitate the connection between the pen body, the throttle valve and the vacuum generator. .

The pen-type suction jig of the utility model can absorb products flexibly, quickly and conveniently, and the size of the gravitational force can select a suitable vacuum generator according to the required suction force, which can ensure sufficient suction force; throttle valve and vacuum generator The device is connected in parallel between the air inlet end of the pen body and the air outlet end of the solenoid valve, so that when absorbing products with static electricity, the air outlet end of the solenoid valve and the external air source enter the throttle valve, and the throttle valve The air source enters the pen body, thereby producing a blowing action, and the product can easily fall off from the pick-and-place product end of the pen body.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in the figure, the pen-type suction jig of the present invention includes a pen body 1, a vacuum generator 2 for vacuuming the pen body 1, a solenoid valve 3 communicating with an external air source, and a device for controlling whether to perform the suction action. Adsorption control switch 4. The solenoid valve 3 is electrically connected to the adsorption control switch 4. In this embodiment, it is safer to sample a power supply voltage of 24V, see FIG. 2 for details.

Different from the prior art, the pen-type air suction fixture of the present invention also includes a throttle valve 5, and the vacuum generator 2 and the throttle valve 5 are connected in parallel to the air inlet end of the pen body 1 and the solenoid valve 3 between the outlet ports.

In the present embodiment, because the preferred solenoid valve 3 is a two-position three-way solenoid valve, the intake end of the two-position three-way solenoid valve is now connected to an external air source through a trachea (the external air source can be sampled from an air compressor. The compressed gas) is connected, and the two gas outlets of the two-position three-way solenoid valve are respectively connected to the air intake end of the throttle valve 5 and the vacuum generator 2 through the air pipe, that is, the air intake end of the throttle valve is connected to the electromagnetic valve. One of the outlet ports of the valve is connected, while the inlet port of the vacuum generator is connected with the other outlet port of the solenoid valve. Of course, if the simplicity of the structure is not considered, it can also be realized by using two two-way solenoid valves.

For the convenience of the pen-type suction fixture of the present utility model to absorb products with the same shape and type, the pen body 1 includes a nib 1.1 for picking and placing the product, and a pen container 1.2 for carrying the nib 1.1, so that it can Individually design the nib structure to adapt to products with different shapes and types. In this embodiment, the nib and the pen container are detachably connected by means of threaded connection, which is convenient for disassembly and assembly. And between the air inlet end of described pen body 1 and the air outlet end of throttle valve 5 and vacuum generator 2, a three-way joint is also provided with to realize communication and connection. The required connecting parts are detachably connected by threaded connection.

For the convenience of operating the adsorption control switch 4, the adsorption control switch 4 is mounted on the wall of the pen body 1. In this embodiment, it is mounted on the wall of the pen holder, and can be easily manipulated at any time.

The working principle of the pen type suction fixture of the present utility model is:

When the tip of the nib is pressed against the surface of the product, the air is cut off from entering the pen holder, the adsorption control switch (also called patch switch) is pressed, the solenoid valve is turned on, the external air source enters the vacuum generator, and the vacuum generator generates negative air pressure, and the pen holder When the patch switch is released, the circuit is disconnected, the magnetic force of the solenoid valve disappears, the solenoid valve closes, and the vacuum generator enters natural air, negative air pressure disappears, the suction force at the front end of the nib disappears, and then enters the throttle valve through the other air outlet of the solenoid valve and an external air source (in this embodiment, a small throttle valve is sampled, which has a small structure and is convenient to take and place). The air source enters the pen body, thereby producing a blowing action, and the product falls off the front of the nib easily.
