Description

Brake pad forming device for automobile

Technical Field

The present invention relates to a brake pad forming apparatus for an automobile, and more particularly, to a brake pad forming apparatus for an automobile suitable for various kinds of small-volume production for the purpose of supply for maintenance and marketing.

Background

Generally, brake pads for automobiles are manufactured and installed separately according to vehicle types because the size and form of the brake pads, the characteristics of friction materials, and the like are different according to the vehicle types.

Furthermore, in the production of brake pads, finished vehicle manufacturers are required to produce them in large quantities for the type of vehicle, while in the repair market, they are required to produce them in small quantities for the type of vehicle.

Particularly, in the production of brake pads for automobiles, it is necessary to replace a mold frame from a molding machine according to the type of vehicle to be used, and complicated and severe working processes are required from the supply of upper and lower layer materials and a back plate to the press molding and the discharge of the brake pads. Therefore, according to these requirements, a single-variety mass-production brake pad forming device for a finished vehicle manufacturer and a multi-variety low-volume-production brake pad forming device for a repair market are separately manufactured and used.

That is, in the case of a single-product mass-production brake pad forming apparatus used in a finished vehicle manufacturer, for example, a registered patent No. 10-1784782, "an automobile brake pad forming apparatus including a friction material temporary forming member," and a registered patent No. 10-1784782, "an automobile brake pad temporary forming apparatus having a back plate preheating member," etc., a forming operation is continuously and repeatedly performed by a turntable having a plurality of forming frames. In addition, in the case of a brake pad forming apparatus for mass production used in the maintenance market, such as a brake pad forming apparatus for an automobile disc brake disclosed in japanese laid-open patent No. 10-2008-0097002 "and a brake pad forming apparatus for an automobile disclosed in japanese laid-open patent No. 10-2019-0059386", a forming frame composed of an intermediate mold and a lower mold is replaceably attached to a lifting frame, and when the lifting operation is performed by a master cylinder, the pressing forming is performed by an upper mold opposing the forming frame.

Therefore, in the case of a single-variety brake pad molding apparatus for mass production used in a finished vehicle manufacturer, the replacement cycle of the mold frame is long, and productivity is expected to be improved to the extent that automation can be achieved. However, in the case of a brake pad forming apparatus for mass production for the repair market, not only the replacement cycle of the mold frame is very short, but also the replacement work is difficult and severe, resulting in a significant drop in productivity, and in particular, in the molding work, since the upper and lower layer materials and the back plate are supplied to the mold frame located inside the frame and the brake pad is difficult to be taken out after molding, automation cannot be achieved, thereby further resulting in a significant drop in productivity.

Before the molding operation, molding frames 412 having different molding chamber shapes are attached to the molding machines 400, and the molding operation is performed by the selected molding machine 400 according to the type of the brake pad to be received.

That is, after the preparation for forming the back plate is completed, the upper layer material supply container containing the upper layer material is introduced into the elevator 214 provided in the elevator unit 210 of the upper layer material weighing machine 200, and ascends by the elevator 214, the upper layer material supply container ascended by the elevator 214 enters the rotary frame 224 installed in the container body 222 of the supply hopper unit 220, and the upper layer material supply container entering the rotary frame 224 rotates by the rotary frame 224 rotated by the working cylinder 227, and the upper layer material in the upper layer material supply container is supplied to the mixing hopper unit 230 while falling.

The upper layer material supplied to the mixing hopper unit 230 is mixed by the mixing blade 236 and the conveying screw 238, discharged from the discharge port, and supplied to the weighing unit 240 by dropping. The upper layer material supplied to the weighing unit 240 is quantitatively weighed by the two-stage

vibratory feeders

242, 244 and the weighing cup 246 having the load cells with different vibration speeds and falls down to be supplied to the cup 259 having the conveying unit 250.

At this time, the cups 259 of the transfer unit 250 are connected to the auxiliary moving bodies 257 provided on both sides of the auxiliary guide table 254, are each connected to the same number of molding chambers as that of a certain molding machine 400, are operated in the left-right direction by the horizontal cylinders 255 and the LM guides provided between the auxiliary guide table 254 and the auxiliary moving bodies 257, and are operated in the front-back direction by the moving bodies 253 operated by the timing belts and the LM guides connected to the motor from the guide table 251, and receive the supply of the upper layer material weighed by the weighing unit 240 in the left-right direction.

The cup 259 of the transfer unit 250 that receives the upper layer materials weighed by the weighing unit 240 is a cup 520 that is provided in the upper layer material supply/screening machine 504 and that moves forward from the guide table 251 through the moving body 253 on the left and right sides, and then drops and supplies the upper layer materials in the cup 259 to the gantry loader 500 by the rotation of the motor 258.

The upper layer material supply/screening machine 504 of the gantry loader 500 that receives the upper layer material from the transfer unit 250 moves along the horizontal guide table 502 by a pinion and a rack gear connected to the motor 508, reaches the upper part of the molding frame 412 of the selected molding machine 400, rotates the discharge roller 518 by the motor 516, drops the upper layer material in each cup 520, and supplies the upper layer material to each molding chamber of the molding frame 412, and then the screening machine 528 operates from the horizontal guide table 502 to the left and right by the horizontal moving body 510, operates up and down by the vertical cylinder 522, and rotates the screening rod 526 by the motor 524, thereby performing a screening operation on the upper layer material supplied to each molding chamber of the molding frame 412.

At this time, before the upper layer material is supplied by the gantry loader 500, the forming frame 412 of the forming machine 400 is protruded forward along the support frame 408 from the crane 404 by the horizontal cylinder 410, and the upper layer material supply and screening work by the upper layer material supply and screening machine 504 is realized in a state where the forming frame 412 is protruded.

After the upper layer material is supplied to the molding frame 412 of the molding machine 400 and the screening work is performed, the robot main body 612 of the gantry robot 600 moves forward of the selected molding machine 400 along the moving body 610 operated by the pinion 606 and the rack gear 608 connected to the motor 604 from the guide table 620, and the upper layer material supplied to each molding chamber of the molding frame 412 is compacted after the air gripper 636 of the gripper 614 grips the compactor 616 placed on the placing table of the moving body 610.

After the upper layer material is supplied to the molding frame 412 of the selected molding machine 400 and compacted by the compactor 616 of the gantry robot 600, the lower layer material received from the outside is weighed by the elevating unit, the left and right feed hopper units, the left and right mixing hopper units, the left and right weighing units, and the conveying unit of the lower layer material weighing machine 300 and supplied to the cup 528 of the lower layer material supplying and screening machine 506 of the gantry loader 500, and then the lower layer material supplying and screening machine 506 moves along the horizontal moving body 514 from the horizontal guide table 502 to the upper portion of the molding frame 412 of the molding machine 400, and after the lower layer material is supplied to the upper layer material of each molding chamber, the screening work is performed by the screening machine 536, as in the same operation as the previous operation of weighing the upper layer material by the upper layer material weighing machine 200.

Further, when the upper layer material and the lower layer material are supplied to the molding frame 412 of the selected molding machine 400, the back sheet loaded in multiple stages by the back sheet loader 620 of the gantry robot 600 is attracted by the electromagnet 666 provided in the moving body 664 of the transfer machine 624 and supplied between the receiving frame 670 of the back sheet centering machine 626 and the pressing frame 674, and then the back sheet centering machine 626 operates the pressing frame 674 by the working cylinder 672, arranges the back sheets supplied between the receiving frame 670 and the pressing frame 674 in the left-right direction, and operates the pressing table 678 by the working cylinder 676 so that the back sheets are arranged in the front-back direction. The brake pads arranged in the front, rear, left, and right directions by the back plate centering machine 626 are attracted by the electromagnet 638 provided in the gripping claw 614 of the robot main body 612 after the lower layer material is supplied, and are supplied to the lower layer material in each molding chamber.

After the upper layer material, the lower layer material, and the back plate are sequentially supplied to the respective molding chambers of the molding frame 412 of the selected molding machine 400, the molding frame 412 is lifted and lowered along the lift frame 404 by the main cylinder in a state where it is moved inward along the support frame 408 by the horizontal cylinder 410, and press molding is performed by contact with the upper mold 461, and after press molding of the brake pad, the molded frame 412 is released from the molding frame 412 by the release cylinder 416 in a state where it is moved forward by the horizontal cylinder 410, and the released brake pad is attracted by the electromagnet 638 provided in the grip 614 of the robot main body 612 and supplied to the primary discharging conveyor 628, and is conveyed along the primary discharging conveyor 628 and the secondary discharging conveyor 630, and discharged to the outside.

After the brake pad molded by the selected molding machine 400 is released from the mold, the air chuck 636 of the chuck 614 of the robot main body 612 holds the brush-used release agent dispenser 632, the brush 696 rotated by the motor 695 brushes and cleans the molding chambers of the molding frame 412, and the cleaned release agent dispenser 698 dispenses and applies the release agent to the molding chambers, so that the brake pad can be continuously and repeatedly molded by the selected molding machine 400.

On the other hand, since the molding machine 400 used for molding the brake pads is selected from a plurality of molding machines 400, when the molding machines 400 are different in the type of brake pad to be molded, it is not necessary to replace the molding frame 412, and a plurality of types of brake pads as many as the number of the molding machines 400 can be produced.

In particular, when different types of brake pads cannot be molded by only a few molding machines 400 having different molding frames 412, as shown in fig. 17 and 18, when a molding operation is performed using the selected molding machine 400, in the other molding machine 400, the auxiliary guide table 426 extended from the fixed guide table 406 is coupled to the connection hole 424 formed at both sides of the rear of the crane 404, and the fixing pin 422 connected to and fixed to the horizontal cylinder 410 of the crane 404 is separated from the pin holes 418 and 420, the molding frame 412 is protruded rearward along the auxiliary guide table 426 together with the support frame 408, and the other molding frame 412, which is different from the molding chamber, is replaced, the replaced molding frame 412 enters inwardly along the auxiliary guide table 420 together with the support frame 408, and thereafter, the horizontal cylinder 410 is fixed to the crane 404 by fixing pins 422 coupled to the pin holes 418 and 420, whereby the molding work can be performed using the replaced molding frame 412.

The invention is therefore suitable for the production of many varieties in small quantities for the maintenance market, while at the same time making it possible to automate almost all the operations required in the brake pad forming process. By selectively using several molding machines 400 having different molding frames 412 and replacing the molding frames 412, a wider variety of products can be produced. Even when the molding frame 412 of a certain molding machine 400 is replaced, molding can be continued using the remaining molding machines 400 for the production of a plurality of products, thereby preventing a reduction in productivity due to the replacement of the molding frame 400.

As described above, although the present invention has been described with reference to the preferred embodiments thereof, those skilled in the art can make various modifications and variations to the present invention and implement them without departing from the scope of the spirit and the field of the present invention as set forth in the claims.
