The brake pad P is provided as a means for stopping the rotation of the brake discs of a passenger car or a passenger car or a large vehicle with frictional force and braking the vehicle. As shown in Fig. 1, the friction material a and the friction material a And has a structure of a pad plate (b) which is a steel plate material to be supported.

A rough surface of a friction material (a) formed in the form of a block on the upper surface of the pad plate (b) of the above steel sheet material is subjected to a first roughing planarization process using a grinding apparatus, The rough surface of the friction material block is subjected to slanting processing and then subjected to slot processing so that the friction material (a) is branched into nuts as shown in FIG. 1, and then the friction material (a ) Scoring process and the coating of the pad plate.

In the conventional case, the surface grinding process of the friction material (a), the finishing process, the chamfering process for forming the slope, and the slotting process for forming the slit in the central longitudinal direction are performed by independent grinding machines The productivity is greatly lowered and the precision of the processed friction material (a) is lowered.

As a method for overcoming this problem, Korean Patent Registration No. 11943 (published on Sep. 6, 1996; a friction material continuous grinding device for brake pads) which is registered and registered in the Korean Intellectual Property Office has been disclosed.

Quot ;, the friction material block 14 of the brake pad 10 has a surface 16 having a flat surface and sloped surfaces formed on both sides thereof and a slot 20 is formed at the center thereof A reciprocating pedestal 26 carrying the brake pads 10 is mounted on the guide rail 24 of the base and is provided with a roughing grinder 46, a finishing grinder 48, The distance between the intermediate point between the roughing grinder 46 and the finishing grinder 48 and the intermediate point between the slope grinder 50 and the slot grinder 52 in the case where the grinder 50 and the slot grinder 52 are disposed, The pad fixing plates 38 and 40 are provided on the front end and the rear end side of the reciprocating pedestal 26 with a distance corresponding to the number of the pad fixing plates 38 and 40, A cylindrical electromagnet block 44 is disposed on the bottom surface side thereof, a finishing grinder 48, A supporting plate 58 supporting several electromagnet blocks 56 is installed between the inclined surface grinders 50 and a first pad relay assembly 54 for elevating and lowering operation is provided and a plurality of electromagnet blocks 70 And a second pad relay assembly 73 capable of reciprocating to the discharge end side of the base 22 is provided on the support plate 72 supporting the brake pad 72. [ .

In this prior art, there is an advantage in that the roughness machining and finishing machining, the slope machining (chamfering machining) and the slot machining are sequentially performed, so that the friction material of the brake pad is easily processed by one grinding device, , There is a problem that the entire grinding device is arranged long because each of the machining portions is sequentially arranged.

In addition, as for the work process of the prior art described above, roughing and finishing are sequentially performed after the first workpiece is seated on the conveyance table for conveying the reciprocating workbench, that is, the pad fixing plate, and the workpiece is taken out from the first pad relay assembly A brake pad, which is a first machined workpiece, is loaded on another pad fixing plate which is separately provided on the rear end side, and then the slope machining (chamfer machining) and the slot machining are sequentially performed, and then the second pad relay assembly And then discharged to the side of the tray which can be constituted by a separate conveyor belt or the like. In this case, the pad fixing plate on which the workpiece is firstly loaded is rotated in a predetermined direction After the stroke distance is transferred, the pad fixing plate is taken out by the first pad relay assembly and the pad fixing plate is moved backward to mount a new workpiece The process of sequentially performing chamfering and slotting on the first processed workpiece, and then loading and rotating the first and second processed workpieces by the second pad relay assembly and then to the transmission relay lever side, A pad relay assembly and the like are required.

So that the measurement can be performed while maintaining the sensitivity state.

In other words, the dust measurement control section C determines that the degree of contamination is high when the amount of received light of the infrared ray receiving means B is low, and outputs a control signal to increase the light amount of the infrared ray transmitting means A If the amount of light received by the infrared ray receiving means C is too high, a contamination-free state or a precise measurement becomes difficult. Therefore, a control signal is outputted so as to lower the light amount of the infrared ray transmitting means A That is, it is necessary to keep the amount of infrared transmission light in an appropriate state. The infrared ray amount measured through the infrared ray receiving means is accurate and the dust amount can be more precisely predicted. Therefore, the dust amount data measured by the dust measurement control unit of the present invention can output the dust measurement result with high reliability.

In the present invention, when the dust measurement control unit C outputs a control signal in order to facilitate the change of the light amount of the infrared ray transmission unit, the transmission control unit 1 recognizes the control signal and drives the infrared ray transmitter conversion unit to perform the most appropriate infrared ray transmission .

The mounting electromagnet 2b is positioned. Accordingly, when the operating rod is lowered by one step, the infrared ray transmission element 4a comes close to the second concave lens 5b and outputs infrared light through the second concave lens 5b.

The first fixing electromagnet 2d-the first moving electromagnet 2a, the second fixing electromagnet 2e-the second floating electromagnet 2b, and the second fixing electromagnet 2b are controlled by the transmission control unit 1 in the control for the one- The third fixed electromagnet 2f and the third floating electromagnet 2c are given a repulsive force signal and the first fixed electromagnet 2d-the second floating electromagnet 2b and the second fixed exclusive magnet 2d- When the actuating signal is applied to the third moving electromagnet 2c, the actuator 3 is raised so that the second mounting electromagnet 2b is positioned at the position of the first fixing electromagnet 2d and the second mounting electromagnet 2b is positioned at the position of the second fixing electromagnet 2e The third mounting electromagnet 2c is located.

The present invention is further characterized in that a motion speed adjusting means 6 is further provided and is formed at the lower end of the actuator 3 so as to form a plurality of fitting holes 6a in the actuator 3, The movement speed of the actuator 3 can be adjusted by inserting a weight adjusting pin 6b for adjusting the weight of the actuator in the hole.

That is, the weight adjusting pin 6b is inserted into the fitting hole 6a. If one weight adjusting pin is provided, the working rod is light and thus it is possible to flow rapidly. When the three weight adjusting pins are installed, Slow flow is possible.

The movement speed control means controls whether the movement of the actuator 3 is fast or slow. If the actuator 3 moves too fast, the sensitivity increases. If the actuator 3 moves too slowly, So that the user can selectively control the movement of the actuator 3.

That is, if the user wants to increase the sensitivity, only one weight control pin 6b is inserted and coupled, and if the sensitivity is to be lowered, up to three weight control pins 6b are inserted and coupled.

It is needless to say that the number of the fitting holes 6a and the weight adjusting pins 6b may be varied according to need. In the embodiment of the present invention, three fitting holes 6a and three weight adjusting pins 6b ), So that the explanation can be made more convenient.

In addition, according to the present invention, when dust is detected as a reference or more and a notification situation occurs, the dust measurement unit (3000) displays the notification status through the communication signal automatic output unit (1000) The automatic output unit 1000 includes a power supply unit 1110, a first switching transistor, a second switching transistor, a third switching transistor, a fourth switching transistor, a relay switch, a first circuit connection switch sw1, A second circuit connection switch sw2, and a communication control unit 1120. [
The communication signal automatic output unit 1000 is electrically connected to the dust measuring unit 2000 through wire or wireless. When the measured dust of the dust measuring unit is equal to or more than the reference value, the communication signal automatic output unit 1000 outputs an alarm signal through the communication signal automatic output unit.

The power source unit 1110 applies power to its own power source.

The first switching transistor Q1 switches the circuit according to a switching signal input to the base.

The second switching transistor Q2 operates in accordance with the operation of the first switching transistor and switches the power source output from the power source unit.

The third switching transistor Q3 switches the circuit according to a switching signal input to the base.

The fourth switching transistor Q4 is provided on the other side of the output terminal of the power supply unit to switch the power supply unit output from the power supply unit.

The relay switch RL1 is coupled to the output terminal of the fourth switching transistor and generates a magnetic force when the fourth switching transistor is switched.

The first circuit connection switch sw1 performs a function of energizing the circuit by pulling the iron piece by the relay switch.

The second communication signal output power switch sw2 serves to induce a communication signal to be output through the communication signal output unit 1150 by supplying power to the communication signal output control unit 1140 while the iron wire is pulled by the relay switch do.

The communication controller 1120 switches the third switching transistor and the fourth switching transistor to switch the relay switch so that the first circuit connection switch and the second communication signal output power switch are switched, A first circuit connection switch configured to switch the first switching transistor and the second switching transistor while turning off the switching transistor and the fourth switching transistor and to turn off the relay switch and simultaneously to be interlocked with the first switching transistor and the second switching transistor And maintains the communication state by continuing the switching state of the second communication signal output power switch.

In addition, the present invention is characterized in that it comprises a circuit board 1131 for operation, a wire piece 1132 for connection to a power supply for operating a communication signal control unit, a first resilient holding means 1133, a second resilient holding means 1134, (1133a), and a manual operation switch (1135).

The circuit-operating piece 1131 contacts the first circuit connection switch sw1 and relays the power delivered from the second switching transistor to continue the flow of power.

The communication signal output control unit power connection iron piece 1132 is designed to operate in conjunction with the circuit operation iron piece 1131. When the circuit operation iron piece 1131 is turned on, power is supplied to the communication signal output control unit 1140 Thereby inducing the communication device to operate.

The first elastic holding means 1133 is provided at the lower end of the circuit operation steel plate 1131 so that the first circuit connection switch sw1 and the circuit operation wire 1131 are always kept in the off state when the relay switch is not operated .

The second elastic holding means 1134 is installed on the upper portion of the first circuit connecting switch sw1 and is spaced apart from the first elastic holding means by a predetermined distance. When the relay switch is operated, the circuit breaker 1131 is pulled to be coupled with the first resilient holding means 1133 while the first resilient holding means is overlapped, and at the same time, the first circuit connecting switch sw1 is switched So that even if the operation of the relay switch is stopped, the state of attaching the circuit breaker 1131 continues to maintain the power supply state through the first switching transistor and the second switching transistor. At this time, when the circuit breaker 1131 is operated by the operation of the relay switch, the communication piece 1132 is automatically operated to output the communication signal to the outside.

The gap maintaining means 1133a guides the second elastic holding means 1134 and the first elastic holding means 1133 to be engaged with each other while maintaining a constant gap without being directly coupled to each other when the first elastic holding means 1134 and the first elastic holding means 1133 are engaged, 1133 and the second resilient holding means 1134 can be more smoothly separated from each other by the action of the gap maintaining means at the time of disassembly. If the gap maintaining means is not present, the first elastic holding means 1133 and the second elastic holding means 1134 are directly attached to each other, so that mutual separation becomes difficult later. Accordingly, in the present invention, the first elastic holding means 1133 and the second elastic holding means 1134 can be easily separated by further providing the gap holding means 1133a.

The manual operation switch 1135 is connected to a wire for circuit operation and a wire for connection to a communication signal output control unit. When the user operates the wire to interrupt the operation of the communication signal, So that the operation of the communication signal output unit is stopped so that the communication signal is no longer output.

Hereinafter, the operation of the communication signal automatic output unit 1000 will be described.

First, a control relation for outputting a communication signal will be described. In the control unit, a power is applied to the third switching transistor and the fourth switching transistor to operate the relay switch RL1. Accordingly, the first circuit connection switch sw1 and the communication signal output power switch sw2 are turned on by the operation of the relay switch, and the power is applied to the communication signal output control unit 1140 to display the communication signal.

When the first circuit connection switch sw1 is operated, the control unit interrupts the operation of the third switching transistor and the fourth switching transistor to cut off the operation of the relay switch, and simultaneously operates the first switching transistor and the second switching transistor.

On the other hand, if the operator turns off the first circuit connecting switch and the communication signal output power switch in the middle of outputting the communication signal, the control unit recognizes this, and then the third switching transistor and the fourth switching transistor are operated, It is possible to keep the closed circuit while moving the iron piece and at the same time return the power outputted to the communication signal control part 1140 to continuously operate the communication signal output part 1150.

That is, according to the present invention, if the notification factor is not solved, the communication signal is continuously output to induce the notification factor to be solved.

That is, when a switching signal is applied to the third switching transistor, the fourth switching transistor, the first switching transistor, and the second switching transistor in the control unit, the communication signal is automatically output by returning the power source again, It is possible to induce the operator to reliably solve the cause of the communication signal.

If it is no longer necessary to output a communication signal, the control unit no longer applies a power supply signal to the first switching transistor, the second switching transistor, the third switching transistor, and the fourth switching transistor. ) Can be manually operated by a user to interrupt the communication signal.
