Error-preventing method of the invention are as follows: three-layer sealed pad includes upper piece gasket, middle gasket of overlapping assembling up and down
With bottom sheet gasket, wherein upper piece gasket is identical with bottom sheet gasket, in the phase of upper gasket and bottom sheet subgasket edges
A mistake proofing notch, corresponding position non-notch of the middle gasket in mistake proofing notch are respectively processed with position；By three layers after overlapping
Gasket is placed on predetermined position, and lower section is arranged error-proof detection device, and error-proof detection device includes pressure sensor and is located at pressure
Above force snesor, the thimble of upper end face mistake proofing notch；Three-layer sealed pad is pushed, and detects three layers by error-proof detection device
Whether gasket stacks sequence wrong.
Based on above-mentioned technical characteristic, error-proof detection device is connected with programmable logic controller (PLC).
The present invention is especially suitable for the dresses of automobile engine gasket product similar in three layers and middle layer appearance and upper and lower level
With mistake proofing, the generation of defective products can be effectively reduced.Pass through the feedback to thimble testing product mistake proofing gap position height, judgement
Whether machine stops working and can alarm according to this, to play the role of effective mistake proofing.

Specific embodiment
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.These embodiments are only used for
Illustrate the present invention, and not limitation of the present invention.
In the description of the present invention, it should be noted that term " center ", " longitudinal direction ", " transverse direction ", "upper", "lower",
The orientation or positional relationship of the instructions such as "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom" "inner", "outside" is
It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of description of the present invention and simplification of the description, rather than instruction or dark
Show that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as pair
Limitation of the invention.In addition, term " first ", " second " are used for description purposes only, it is not understood to indicate or imply opposite
Importance.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, can also can be indirectly connected through an intermediary
Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood as the case may be
Concrete meaning in the present invention.
In addition, in the description of the present invention, unless otherwise indicated, the meaning of " plurality " is two or more.
As shown in Figures 1 to 4, three-layer sealed pad overlaps assembling up and down, upper piece gasket 1 and 2 appearance of bottom sheet gasket with
Thickness is identical, and upper piece gasket 3 is similar to upper piece gasket 1 and 2 shape of bottom sheet gasket；It is sealed in upper gasket and bottom sheet
The same place at pad edge respectively processes a mistake proofing notch, middle gasket 3 the mistake proofing notch corresponding position non-notch,
Three-layer sealed pad after the installation is completed is placed on predetermined position, that is, is placed at 5 absolute altitude of datum level, thimble 4 is upward through benchmark
Face 5 and opposite mistake proofing notch.The height that mistake proofing gap position is detected by thimble, when the height in the relative datum face 5 of thimble is
When the thickness h of mistake proofing notch, it is correct that three-layer sealed pad overlaps assembling up and down.Fig. 1 to three-layer sealed pad shown in Fig. 3 planar shaped
Shape is only a kind of signal, be can have any shape.
As shown in figure 5, piece gasket setup error in the middle, when being placed on upper layer, the height in thimble relative datum face 5 is exactly
2h；As shown in fig. 6, piece gasket setup error in the middle, when being placed on lower layer, the change in elevation in thimble relative datum face 5 is exactly
0。
In the present invention, error-proof detection device is that thimble is used cooperatively with pressure sensor, and pressure sensor is mounted on thimble
Lower section, the mechanical movement of thimble make pressure sensor generate pressure signal.It, can be to when thimble relative datum 5 different height of face
It is lower to generate different pressure.If the height in thimble relative datum face 5 is the thickness h of mistake proofing notch, pressure sensor is generated
Pressure is normal pressure.When the pressure that pressure sensor is subject to is normal pressure, it is correct that three-layer sealed pad overlaps assembling up and down.
Fig. 7 show one embodiment of the present of invention, thimble 4 and the mountable fixture 9 in mash welder of pressure sensor 10
On, the detection mouth that thimble is opened from fixture is pierced by, and the lower part of thimble 4 is pressure sensor 10, and the three-layer sealed pad 8 overlapped is placed on
On predetermined position, that is, it is placed on fixture 9.Being suspended in 9 top of fixture is pressing device 7, and pressing device 7 is plate, spot welding head 6
It on pressing device 7, can be moved downwardly together with pressing device 7, pressing device 7 can be first by three-layer sealed pad before spot welding
8 compress, and the three-layer sealed pad 8 after compression makes the thimble 4 being pressurized that pressure is transferred to pressure sensor 10, and pressure sensor 10 is examined
When what is measured is normal pressure, show that three-layer sealed about 8 pad overlapping assembling is correct, error-proof detection device can be patrolled by programmable
The electric current for collecting controller control spot welding head 6 is welded when correct to the energization of spot welding head 6.If pressure sensor 10 detects
Pressure when not being normal pressure, then error signal is provided by programmable logic controller (PLC).
It is herein only a kind of citing, three-layer sealed pad can also be connected by other ways such as rivetings, need to be only connected and fixed
The preceding detection for carrying out rigging position.
Therefore the present invention can judge whether machine stops work by the pressure feedback to thimble testing product mistake proofing gap position
Make and alarm, to play the role of mistake proofing.Programmable logic controller (PLC), pressure sensor belong to the prior art, pressure sensing
Device may, for example, be piezoresistive pressure sensor, spring-tube pressure sensor etc..
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
Also it should be regarded as protection scope of the present invention.
