Description

Heating furnace roller fracture detection device

[ technical field ] A method for producing a semiconductor device

The utility model relates to a heating furnace cylinder fracture detection device.

[ background of the invention ]

In the company, the length of a roller in a heating furnace is more than 50 meters, the roller in a pollution area of the heating furnace is broken sometimes due to various uncertain factors in the normal production process of equipment, and production line staff cannot find the roller breakage at the first time. When production line staff find that the heating furnace ejection of compact is unusual, just can inspect whether the cylinder of heating furnace has the fracture, often the heating furnace is inside to have blocked up a lot of tablets this time, because the heating furnace is 930 ℃ of high temperature environment when normal production, these tablets can't clear up through normal means, can only dismantle the cylinder in the region that blocks the tablet, drop the lower extreme of heating furnace with the tablet by force, but will pound the heating rod of lower extreme bad at this moment. If the heating rod of the heating furnace is seriously damaged, the heating rod needs to be cooled and stopped, and the heating rod can be produced after being replaced, so that the blockage of the heating furnace brings great trouble to the production, and the long-time shutdown is caused.

Therefore, it is necessary to provide a new heating furnace roller breakage detection device to solve the above problems.

[ Utility model ] content

A primary object of the utility model is to provide a heating furnace cylinder fracture detection device, discovery cylinder that can be timely is unusual, and the line is shut down is produced in timely arrangement maintenance, avoids causing serious putty problem because of the cylinder damages.

The utility model discloses a following technical scheme realizes above-mentioned purpose: a heating furnace roller breakage detection device comprises a supporting shaft, an induction sheet, a sensor and a PLC (programmable logic controller), wherein the supporting shaft is fixed on a roller and synchronously rotates along with the roller, the induction sheet is fixed on the supporting shaft, the sensor is used for inducing the induction sheet, and the PLC is in circuit connection with the sensor and controls an alarm to give an alarm if a signal of the sensor cannot be received within a set time.

Further, the support shaft is installed on an outer side surface of an end cover of the drum, and the sensor is fixed on a fixing plate.

Further, the end of the end cap is opposite the rotary drive end of the cylinder.

Furthermore, the tail end of each roller is provided with one sensor and one induction sheet, and all the sensors are communicated with the PLC circuit.

Furthermore, the PLC controller also comprises a touch screen, and the touch screen is connected with the PLC controller through a circuit.

Further, the alarm is installed on the hot press where the roller is located.

Further, the set time is the time of one rotation of the drum.

Compared with the prior art, the utility model relates to a heating furnace cylinder fracture detection device's beneficial effect lies in: can the very first time discover cracked cylinder, in time maintain the cylinder that damages, the condition of serious putty then can not appear again in the heating furnace, very big improvement production efficiency, avoided long-time shut down the wait state to appear.

[ description of the drawings ]

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a schematic structural diagram of a control frame according to an embodiment of the present invention;

the figures in the drawings represent:

100 heating furnace roller breakage detection device; 101 a roller; 102 an end cap;

1 supporting a shaft; 2, an induction sheet; 3, a sensor; 4, an alarm; 5, a PLC controller; 6, a touch screen; 7 fixing the plate.

[ detailed description ] embodiments

Example (b):

referring to fig. 1-2, the present embodiment is a heating furnace roller breakage detecting device 100, which includes a supporting shaft 1 fixed on a roller and rotating synchronously with the roller 101, a sensing piece 2 fixed on the supporting shaft 1, a sensor 3 sensing a signal of the sensing piece 2, and a PLC controller 5 electrically connected to the sensor 3 and controlling an alarm 4 to give an alarm if the signal of the sensor 3 is not received within a set time.

In this embodiment, the support shaft 1 is mounted on the outer side surface of the end cap 102 of the cylinder, the sensor 3 is fixed on a fixing plate 7, and the end of the end cap is opposite to the rotary driving end of the cylinder. Under normal conditions, one end of the roller is driven by a servo motor, a belt or a chain or a gear to realize rotation, and the other end of the roller is erected on a bearing seat to realize follow-up. In order to avoid that the driving end of the cylinder is still rotated after the cylinder is broken, if the sensor 3 and the sensing piece 2 are installed at the end, the breakage of the cylinder may not be detected in time. Therefore, the present embodiment can effectively avoid the above problem by installing the sensing piece 2 and the sensor 3 at the following end of the roller.

This embodiment all is provided with a sensor 3 and response piece 2 at the end of each cylinder, then communicates all

sensors

3 and 5 circuit of PLC controller, and this embodiment still is provided with a touch-sensitive screen 6, and touch-

sensitive screen

6 and 5 circuit connection of PLC controller can show through touch-sensitive screen 6 whether sensor signal on all cylinders is normal.

The alarm 4 is mounted on the hot press on which the cylinder is located.

The set time is the time for rotating the roller for one circle, and can be flexibly set according to the actual condition.

The built-in procedure of PLC controller 5 can detect the state of each sensor 3, when sensor 3's signal does not change in 15s, can judge that this cylinder is problematic, need the inspection, then PLC controller 5 control siren 4 sends the police dispatch newspaper, can show the cylinder serial number that does not change simultaneously on the touch-sensitive screen 6, siren 4 of while hot press department can report to the police, the heating furnace no longer the ejection of compact, inform maintenance personal inspection cylinder, maintenance personal is according to the accurate cylinder that has the problem of affirmation of alarm information on the touch-sensitive screen, in time, change the cylinder that damages, long-time shut down has been avoided.

The heating furnace roller breakage detection device 100 can find a broken roller at the first time, the damaged roller is maintained in time, the heating furnace cannot cause serious material blockage, the production efficiency is greatly improved, and long-time shutdown waiting situation is avoided.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
