Description

Plane detection device for placing material sheets in place

Technical Field

The utility model relates to the technical field of detection of stamping materials of dies, in particular to a plane detection device for detecting whether material sheets are put in place in a die or not.

Background

In the production process of the stamping parts, the product material sheets are put in place, which is the premise for producing high-quality products.

At present, whether the product material sheets are put in place or not is generally detected by a sensor. In the practical production process, the fitting state of the product material sheet and the mold surface is not uniform every time, and the fitting surface clearance is too large due to the influence of certain reasons, such as uneven material sheet and the like, so that the detection failure of the sensor is caused, and the normal production is influenced.

Referring to fig. 1, a conventional flat panel inspection apparatus is shown. As shown in FIG. 1, the plane detection device is characterized in that a sensor 5 is arranged on one side of a male die of a die through a bracket 4, and the sensor 5 is slightly higher than a die molded surface 3. Due to the fluctuation in height of the material web 1 when it is placed on the mould surface 3, the abutment surface gap 2 may sometimes be made too large, which may cause instability in the detection by the sensor 5 and cause a failure in the detection by the sensor 5. Moreover, this arrangement may cause direct impact of the web 1 against the sensor 5, easily damaging the sensor 5.

The mold surface 3 may include a plurality of turning surfaces, and when the material sheet 1 is placed on the mold surface 3, the height of the material sheet may fluctuate due to the adhesion between the material sheet 1 and the mold surface 3, which sometimes causes the adhesion surface gap 2 to be too large, and when the previous detection method (see fig. 1) is adopted, the detection of the sensor is easily failed. The utility model can effectively solve the problem.

In a preferred embodiment, a bearing arrangement may be provided between the swing portion 13 and the shaft 12 in order to allow the pivotal engagement between the swing portion 13 and the shaft 12 to be as flexible as possible.

In a preferred embodiment, the support 20 may be of a right-angled configuration, the swing portion 13 is mounted on the right-angled vertical surface 10 of the support 20 via the shaft 12, and the sensor 19 is mounted on the right-angled horizontal surface 18 of the support 20 via mounting holes and is located below the swing portion 13.

The swing member 13 has first to third swing ends 11, 21 and 14 provided around the rotary shaft 12. Preferably, the first swing end 11, the second swing end 21, and the third swing end 14 are disposed in order around the rotation shaft 12 (rotation fulcrum).

When the swing part 13 is in a free state, i.e. when no material sheet 1 is laid on the mould profile 3, the first swing end 11 can be swung upwards about the axis of rotation 12 to a position above the mould profile 3 by the force of gravity present at the third swing end 14 and the swinging movement is stopped at the correct position. On the contrary, when the material sheet 1 is laid on the mold surface 3, the material sheet 1 will be attached to the mold surface 3 (there may be a certain gap), and at this time, the first swinging end 11 is pressed by the material sheet 1 to swing downward passively, so as to drive the sensor 19 of the second swinging end 21 to swing and approach downward, so that the sensor 19 senses the swinging motion (i.e. material signal) of the second swinging end 21. While the third swing end 14 will also passively follow the swing.

In a preferred embodiment, the sensor 19 may comprise a proximity sensor or the like.

In a preferred embodiment, the sensor 19 is mounted below the swing portion 13 such that when the swing portion 13 is in the free state, the sensor 19 is positioned just below an escape area on the swing portion 13 between the second swing end 21 and the third swing end 14 such that the sensor 19 senses a no material signal.

In a preferred embodiment, the escape area may be configured as an escape slot 16 formed in the swing portion 13.

Please refer to fig. 2. In a preferred embodiment, a counterweight 15 can be provided at the third oscillating end 14, with a suitable cooperation between the weight of the counterweight 15 and the mass distribution of the oscillating portion 13, so that the second oscillating end 21 and the third oscillating end 14 of the oscillating portion 13 can be maintained at a position lower than the mould profile 3 and in a rest position when the oscillating portion 13 is in a free state.

In a preferred embodiment, the swing portion 13 may be further provided with a lightening hole 17, so as to reduce the weight of the swing portion 13, and simultaneously, to better perform the balance function of the balance weight 15, and to make the swing portion 13 as light and handy as possible, so as to prevent the excessive external force required for swinging.

Further, a lightening hole 17 may be provided in the swing portion 13 at a position between the second swing end 21 and the rotation shaft 12.

When adjusting the weight 15, it is necessary to just allow the pendulum 13 of the device to be normally reset in a free state.

In a preferred embodiment, a limiting structure is further disposed on the bracket 20 between the first swing end 11 and the second swing end 21 for limiting the free upward swing amplitude of the second swing end 21 during the return stroke of the reset, so as to prevent the swing portion 13 from swinging left and right.

According to the utility model, the sensing distance of the sensor 19 is enlarged by arranging the swing part 13 and the counterweight mechanism (the counterweight 15), so that misoperation caused by using a mode of increasing the sensor distance can be avoided, the sensor 19 can work safely in an effective swing angle of the swing part 13, and stable and effective detection is realized.
