Description

자동차 브레이크 패드의 정전도장을 위한 샤워장치{SHOWER DEVICE FOR ELECTROSTATIC PAINTING OF AUTOMOBILE BRAKE PAD}Shower device for electrostatic painting of automobile brake pads {SHOWER DEVICE FOR ELECTROSTATIC PAINTING OF AUTOMOBILE BRAKE PAD}

본 발명은 자동차 브레이크 패드의 정전도장을 위한 샤워장치에 관한 것으로서, 상세하게는 비전도체인 마찰재에도 정전도장이 이루어질 수 있도록 한 것이다.The present invention relates to a shower device for the electrostatic coating of automobile brake pads, and in particular, to the electrostatic coating can be made to the non-conductive friction material.

자동차 브레이크 패드는 전도체인 백플레이트 일면에 비전도체인 마찰재를 성형형성하여 면취 및 그루빙과, 연마와, 스코칭과, 도장 및 소부등의 공정을 단계적으로 거치도록 함으로서 완제품을 얻게 되는데 이러한 제조공정 중 도장 공정시에는 주로 자동화작업에 유리한 정전도장이 이용되고 있다.Automobile brake pads form a non-conductive friction material on one surface of the back plate as a conductor to obtain finished products by chamfering and grooving, polishing, scorching, painting and baking. In the painting process, electrostatic coating, which is mainly used for automated work, is used.

그러나 정전도장은 도장물이 양극(+)전극에 접지되게 한 상태에서 음극(-)전극의 정전도장기에 고전압을 인가하여 양전극간에 발생되는 정전장에 의해 정전도장기로부터 분사되는 도료입자가 도장물에 도포되도록 구성되는 것으로서, 이는 자동차 브레이크 패드가 갖는 구조적인 특성상 많은 문제점들을 야기시키게 된다.However, in electrostatic coating, paint particles sprayed from the electrostatic coating machine are applied by the electrostatic field generated between the two electrodes by applying a high voltage to the electrostatic coating device of the negative electrode (-) electrode while the coating material is grounded to the positive electrode (+) electrode. It is configured to be applied to water, which causes many problems due to the structural characteristics of automobile brake pads.

즉, 정전도장시 자동화작업을 위하여는 자동차 브레이크 패드가 정전벨트를 따라 이송되면서 도장이 이루어지도록 하여야 하고 또 주도장부위는 백플레이트로서 도장을 위하여 브레이크 패드의 백플레이트가 상부에 위치하도록 공급해 주게 되면 비전도체인 마찰재가 정전벨트와 접촉하게 되므로 그 자체로서는 접지가 이루어질 수가 없어 정전도장이 불가능하게 된다.In other words, for automated work during the electrostatic coating, the car brake pads should be transported along the electrostatic belt to be painted. Also, if the main parts are backplates, the brake pads are supplied with the back plate located above. Since the friction material, which is a non-conductor, comes into contact with the electrostatic belt, grounding cannot be made by itself, and thus electrostatic coating is impossible.

따라서 자동차 브레이크 패드의 정전도장을 위하여는 브레이크 패드를 정전벨트 상에 백플레이트가 상부에 위치하도록 공급한 다음 별도의 전극봉을 이용하여 각 브레이크 패드의 백플레이트를 접지시킨 상태에서 정전도장이 이루어지도록 하여야 하므로 접지를 시켜주기가 어렵고 또 브레이크 패드의 이송구간 내에 위치하는 전극봉이 브레이크 패드의 이송을 방해할 우려가 있어 자동화에 매우 불리하다.Therefore, for electrostatic painting of automobile brake pads, brake pads should be supplied so that the back plate is located on the electrostatic belt so that the electrostatic coating is performed while the back plate of each brake pad is grounded using a separate electrode. Therefore, it is difficult to ground, and the electrodes located in the transfer section of the brake pads may interfere with the transfer of the brake pads, which is very disadvantageous for automation.

또한 정전도장 작업전 이루어지는 마찰재의 성형과 연마 및 스코칭작업과정에서 브레이크 패드의 외면에 마찰재 부스러기나 각종 이물질들이 달라붙게 되나, 별다른 세척이나 소제없이 곧바로 도장작업이 이루어지도록 함으로서 도장면이 매끈하지 못하고, 특히 정전도장시에는 도전체인 백플레이트만 도장이 이루어질 뿐 마찰재의 측면에는 도장이 이루어질 수가 없어 도장효과가 반감될 뿐 아니라 미려한 외관을 갖지 못해 상품으로서의 가치가 떨어지게 된다.In addition, during the forming, polishing, and scouring of the friction material before the electrostatic coating, the friction material debris and various foreign substances adhere to the outer surface of the brake pad. In particular, during electrostatic coating, only the back plate, which is a conductor, is coated, but the side of the friction material cannot be painted.

이에 일부특정제품의 경우 도장을 통한 상품성 향상을 위하여 정전도장에 앞서 비전도체인 마찰재 측면에 유체도장을 해 주도록 하고 있으나, 이러한 경우 유체도장공정의 추가로 리드타임 및 작업인력의 증가로 이어져 현저한 생산성 저하를 가져오게 되고 또 이역시 전공정 과정에서 브레이크 패드 외면에 묻어있던 마찰재 부스러기나 각종 이물질들로 인하여 매끈한 표면을 유지할 수가 없게 되는 등 많은 문제점들이 따르게 되는 것이다.In order to improve the productability through painting, some specific products require fluid coating on the non-conductive friction material side before electrostatic coating, but in this case, the additional fluid coating process leads to an increase in lead time and workforce, resulting in remarkable productivity. Many problems are caused by the deterioration and the inability to maintain a smooth surface due to the debris and various foreign matters on the outer surface of the brake pad during the entire process.

본 발명은 브레이크 패드가 깨끗이 세척된 상태에서 도장이 이루어질 수가 있고 또 비전도체인 마찰재에 의한 접지로 정전도장이 이루어지도록 할 수가 있어 자동화에 유리할 뿐 아니라 특히 리드타임의 증가나 추가공정없이도 마찰재의 측면까지 정전도장이 이루어질 수 있도록 한 자동차 브레이크 패드의 정전도장을 위한 샤워장치를 제공하고자 한다.The present invention can be applied in a state where the brake pad is cleanly washed, and the electrostatic coating can be made to the ground by the friction material, which is a non-conductor, which is advantageous for automation, and in particular, the side of the friction material without an increase in lead time or an additional process. To provide a shower device for the electrostatic coating of the brake pads so that the electrostatic coating can be made.

본 발명의 목적은 브레이크 패드가 이송벨트를 따라 이송되면서 워터샤워기와 에어샤워기를 차례로 통과하면서 세척이 이루어지도록 하고 또 그 마찰재에 잔류한 수분에 의해 도전성을 띠도록 한 상태에서 정전도장이 이루어지도록 한 자동차 브레이크 패드의 정전도장을 위한 샤워장치에 의해 달성된다.An object of the present invention is to make the electrostatic coating in a state in which the brake pad is washed along with the conveying belt while passing through the water shower and the air shower in order to be washed and electrically conductive by the moisture remaining in the friction material. It is achieved by a shower device for electrostatic painting of automobile brake pads.

본 발명은 자동차 브레이크 패드(400)가 이송벨트(320)를 따라 이송되면서 정전도장부(200)에 진입하기 앞서 워터샤워기(340)와 에어샤워기(360)에 의한 샤워로 세척되고 또 워터샤워시 그 마찰재에 잔류한 수분에 의해 도전성을 띤 상태에서 정전벨트(220)를 따라 정전도장기(240)를 통과하면서 정전도장이 이루어지도록 함므로서, 도장이 보다 매끈하게 이루어질 수가 있고 특히 별도의 추가구성 없이도 접지가 이루어질 수가 있어 자동화에 매우 유리함은 물론 리드타임의 증가나 추가인력배치 없이도 비전도체인 마찰재의 측면 도장까지도 동시에 이루어질 수가 있어 생산성 향상을 가져올 수 있을 뿐 아니라 마찰재의 측면 도장으로 외관이 미려한 브레이크 패드를 얻을 수가 있게 되는 등의 효과가 있는 것이다.The present invention is washed with a shower by the water shower 340 and the air shower 360 before entering the electrostatic coating unit 200 while the vehicle brake pad 400 is transported along the transfer belt 320 Since the electrostatic coating is made while passing through the electrostatic painter 240 along the electrostatic belt 220 in the conductive state by the moisture remaining in the friction material, the painting can be made more smoothly, and in particular, additional addition. Grounding can be made without configuration, which is very advantageous for automation, and can also be applied to the side coating of the non-conducting friction material without increasing lead time or additional manpower, resulting in improved productivity and beautiful appearance with the side coating of the friction material. The effect is that a brake pad can be obtained.

도 1은 본 발명이 적용된 자동차 브레이크 패드 성형라인의 일부평면구성도로서, 본 발명은 스코칭 가공부(100)와 정전도장부(200) 사이에 샤워부(300)를 갖도록 한 구조로서, 상기 샤워부(300)는 이송벨트(320)와 상기 이송벨트(320)의 상부중앙부에 입구측으로부터 나란히 설치되는 워터샤워기(340) 및 에어샤워기(360)로 구성된다.1 is a partial plan view of the automobile brake pad forming line to which the present invention is applied, and the present invention has a structure in which a shower unit 300 is provided between the scouring processing unit 100 and the electrostatic coating unit 200. The shower unit 300 is composed of a conveying belt 320 and the water shower 340 and the air shower 360 is installed side by side from the inlet side in the upper central portion of the conveying belt (320).

도 2는 본 발명 샤워부의 정면구성도이고, 도 3은 본 발명 샤워부의 평면구성도로서, 본 발명 샤워부(300)를 구성하는 이송벨트(320)와 워터샤워기(340) 및 에어샤워기(360) 중 이송벨트(320)는 스코칭가공부(100)와 정전도장부(200)를 잇기 위한 것으로서, 지지틀(322)을 통하여 수평설치되는데, 샤워시 수분의 원활한 배출을 위하여 무수한 소공을 갖는 망형으로 형성하는 것이 바람직하다.
또한 이송벨트(320)의 입구측에 갖는 워터샤워기(340)는 샤워부스(342)와 상기 샤워부스의 내측 대각선방향에 갖는 2개의 워터분사노즐(344)(346)과 샤워부스(342)의 내측 상부에 부설되어 워터분사노즐의 물공급관을 개폐하는 솔레노이드밸브와 접속되는 감지센서(348) 및 워터분사노즐(344)(346)에 물을 공급하는 워터펌프로 구성된다.2 is a front configuration diagram of the shower unit of the present invention, and FIG. 3 is a plan configuration diagram of the shower unit of the present invention, and the conveying belt 320 and the water shower unit 340 and the air shower unit 360 constituting the shower unit 300 of the present invention. The transport belt 320 is for connecting the scouring processing part 100 and the electrostatic coating part 200, is installed horizontally through the support frame 322, a mesh having countless pores for the smooth discharge of water during the shower It is preferable to form.
In addition, the water shower unit 340 provided at the inlet side of the conveying belt 320 includes a shower booth 342 and two water spray nozzles 344, 346 and a shower booth 342 disposed in the diagonal direction of the shower booth. It is provided with a water pump installed in the upper portion and connected to the solenoid valve for opening and closing the water supply pipe of the water injection nozzle and the water pump for supplying water to the sensor 348 and the water injection nozzles (344, 346).

그리고 이송벨트(320)의 출구측에 갖는 에어샤워기(360)는 샤워부스(362)와 샤워부스 내에 설치되는 에어분사노즐(364)(366) 및 상기 에어분사노즐(364)(366)과 솔레노이드밸브를 통하여 연결되는 에어펌프로 구성되며, 상기 솔레노이드밸브는 워터샤워기(340) 측이 갖는 감지센서(348)와 접속되게 하여 이송벨트(320)를 따라 이송되는 브레이크패드(400)가 감지센서(348) 하부에 이르게 되면, 상기 감지센서(348)의 감지로 워터샤워기(340)와 에어샤워기(360)가 동시에 작동하도록 구성된다.The air shower unit 360 provided at the outlet side of the conveying belt 320 includes a shower booth 362 and air spray nozzles 364 and 366 and the air spray nozzles 364 and 366 and the solenoid installed in the shower booth. The solenoid valve is connected to a detection sensor 348 having the water shower 340 side so that the brake pad 400 transferred along the conveying belt 320 is detected by the air pump. 348, the water shower 340 and the air shower 360 operate at the same time by sensing the detection sensor 348.

다만 이송벨트(320) 상에 공급되는 브레이크 패드(400)는 성형라인의 작업속도에 따라 적정간격을 유지함에 따라 워터분사노즐(344)(346)과 에어분사노즐(364)(366)간의 간격을 브레이크 패드(400) 간에 갖는 간격과 같은 간격을 유지하도록 설치될 경우 워터샤워기(340)측이 갖는 하나의 감지센서(348)에 의해 워터샤워기와 에어샤워기가 동시에 작동하도록 한 것이나, 브레이크 패드(400)간의 간격이 일정하지 못할 경우 워터샤워기와 에어샤워기가 별도의 감지센서에 의해 작동되게 할 수도 있음은 물론이다.However, the brake pad 400 supplied on the conveying belt 320 maintains an appropriate interval according to the working speed of the molding line, so that the gap between the water spray nozzles 344 and 346 and the air spray nozzles 364 and 366 is maintained. When the water shower and the air shower is installed to maintain the same interval as the gap between the brake pad 400, the water shower and the air shower by the one sensor 348 of the water shower 340 side, or the brake pad ( If the interval between 400) is not constant, it is a matter of course that the water shower and the air shower can be operated by a separate sensor.

도 4는 본 발명에 이용되는 정전도장부의 측면구성도로서, 본 발명에서 이용되는 정전도장부(200)는 크게 양극(+)의 정전벨트(220)와, 상기 정전벨트 상부에 설치되어 정역회전하는 모터와 LM가이드에 의해 전후 왕복작동하는 음극(-)의 정전도장기(240)로 구성되는 일반적인 구조로서, 브레이크 패드(400)가 정전벨트(220)를 따라 이송되면서 정전도장기(240)에 의해 정전도장이 이루어질 수 있는 것이면 만족하므로 구체적인 설명은 생략하기로 한다.Figure 4 is a side configuration diagram of the electrostatic coating used in the present invention, the electrostatic coating 200 used in the present invention is largely positive electrostatic belt 220 of the positive (+) and is installed on the electrostatic belt upper It is a general structure consisting of the electrostatic coating machine 240 of the negative (-) the back and forth by the rotating motor and the LM guide, the brake pad 400 is transferred along the electrostatic belt 220, the electrostatic paint 240 If it is satisfied that the electrostatic coating can be made by the) will not be described in detail.

본 발명은 백플레이트 일면에 마찰재가 성형된 브레이크패드(400)가 면취&그루빙부와 연마부와 스코칭가공부(100) 및 냉각컨베이어(500)를 차례로 통과하여 샤워부(300)에 이르게 되면 망형의 이송벨트(320)를 따라 먼저 워터샤워기(340)의 샤워부스(342) 내부로 진입하게 되는데, 이송중 워터샤워기(340) 내부에 갖는 감지센서(348) 하부에 이르게 되면 상기 감지센서(348)의 감지에 의한 솔레노이드밸브의 개방으로 워터분사노즐(344)(346)로부터 물이 분사되어 브레이크 패드(400)의 세척이 이루어짐과 동시에 비도전체인 마찰재에 수분이 침투하여 전체적으로 도전성을 띠게 된다.According to the present invention, when the brake pad 400 having a friction material formed on one surface of the back plate passes through the chamfering & grooving portion, the polishing portion, the scouring processing portion 100, and the cooling conveyor 500, and reaches the shower portion 300, a mesh shape is obtained. Along with the conveying belt 320 of the first to enter the shower booth 342 of the water shower 340, the detection sensor 348 when it reaches the bottom of the sensor 348 of the water shower 340 during the transfer Water is sprayed from the water spray nozzles 344 and 346 by the opening of the solenoid valve by the detection of), and washing of the brake pad 400 is performed. At the same time, water penetrates into the non-conductive friction material to be electrically conductive.

또한 워터샤워기(340)에 의해 마찰재에 도전성이 부여된 브레이크 패드(400)는 계속되는 이송벨트(320)의 회전으로 워터샤워기(340)를 통과하여 곧바로 타측의 에어샤워기(360)가 갖는 샤워부스(362) 내부로 진입하여 에어분사노즐(364)(366)을 통하여 분사되는 에어의 분사력에 의해 워터샤워시 브레이크 패드(400) 외면에 묻어 있는 수분이나 각종 이물질들을 제거해 주게 된다.In addition, the brake pad 400, which is electrically conductive to the friction material by the water shower 340, passes through the water shower 340 by the continuous rotation of the conveying belt 320, and immediately has a shower booth of the other air shower 360. 362, the water and various foreign substances on the outer surface of the brake pad 400 are removed by the water jetting force of the air injected through the air spray nozzles 364 and 366.

다만 이때 에어샤워기(360)의 에어분사노즐(364)(366)을 통한 에어분사는 브레이크 패드(400)의 통과중 짧은 시간동안 이루어지므로 워터샤워기(340)에 의한 워터샤워중 마찰재에 침투한 수분의 완전제거는 불가능하므로 브레이크 패드(400)가 갖는 비전도체의 마찰재는 에어샤워기(360)에 의한 에어샤워후에도 워터샤워시의 잔류수분에 의해 도전성을 띠면서 정전도장부(200)를 잇는 이송컨베이어(600)를 따라 이송되어 푸샤에 의해 정전도장부(200)의 정전벨트(220) 상에 공급되므로 도전성을 띠는 마찰재가 정전벨트(220)와 접촉한 상태로 정전도장기(240)를 통과하면서 정전도장이 이루어지게 된다.However, at this time, since the air spraying through the air spray nozzles 364 and 366 of the air shower 360 is performed for a short time during the passage of the brake pad 400, the water penetrated into the friction material during the water shower by the water shower 340. Since the friction material of the non-conductor of the brake pad 400 is impossible to remove completely, the conveying conveyor connecting the electrostatic coating part 200 is conductive even by the residual moisture of the water shower even after the air shower by the air shower 360. Since it is conveyed along the 600 and supplied by the pusher on the electrostatic belt 220 of the electrostatic coating unit 200, the conductive friction material passes through the electrostatic coating machine 240 in contact with the electrostatic belt 220. The electrostatic coating is made.

따라서 본 발명은 정전도장부(200)의 정전벨트(220)와 접촉하고 있는 브레이크 패드(400)의 마찰재는 워터샤워시의 잔류수분에 의해 도전성을 띠게 되므로 정전벨트(220)의 양극(+)전극을 백플레이트에 인가하여 음극(-)전극이 인가되는 정전도장부(200)로부터 분사되는 분체파우더가 양극간의 강한 정전장에 의해 백플레이트는 물론 그 마찰재에도 전체적으로 달라붙도록 하고 이는 정전도장부(200)로부터 연장형성되는 소부부(700)의 통과중 약180~220℃의 열에 의해 가열 용해되어 완전한 도장이 이루어지도록 함으로서, 정전도장부(200)를 이용한 정전도장시 전극봉등의 도움없이도 정전벨트(220)의 양극(+)전극을 백플레이트에 인가해 줄 수가 있어 자동화작업에 유리하고 또 마찰재의 측면에도 정전도장이 이루어지도록 할 수가 있게 되는 것이다.Therefore, according to the present invention, since the friction material of the brake pad 400 which is in contact with the electrostatic belt 220 of the electrostatic coating part 200 becomes conductive by the residual moisture during the water shower, the positive electrode of the electrostatic belt 220 is positive (+). The electrode is applied to the back plate so that the powder powder injected from the electrostatic coating part 200 to which the cathode (-) electrode is applied adheres to the back plate as well as its friction material by the strong electrostatic field between the anodes. By dissolving by heat of about 180 ~ 220 ℃ during the passage of the small portion 700 extending from the (200) to achieve a complete painting, the electrostatic without the help of the electrode during electrostatic coating using the electrostatic coating 200 The anode (+) electrode of the belt 220 can be applied to the back plate, which is advantageous for automated work and also allows electrostatic coating to be performed on the side of the friction material.
