Description

Technical Field

[0001] This invention relates to the field of friction plate processing equipment technology, specifically to an intelligent adhesive coating device for friction plate processing. Background Technology

[0002] Friction pads are the most critical safety component in a car's braking system, and the effectiveness of braking depends entirely on the friction pads. Drum friction pads are mostly used in drum brakes, which use brake shoes to compress the brake drum to obtain braking force. They can be divided into two types: internally tensioned and externally tensioned. Internally tensioned drum brakes use the inner cylindrical surface of the brake drum as the working surface. Drum friction pads are generally composed of steel plates, adhesive heat insulation layers, and friction blocks. Therefore, during the manufacturing process, the friction pads need to be coated with adhesive. In the past, workers would brush the adhesive with hand tools. This method was not only inconvenient to use and had low work efficiency, but also resulted in uneven adhesive application. With the development of technology and the improvement of adhesive application efficiency, adhesive application equipment is now used.

[0003] However, friction pads vary in size, and most existing adhesive application devices are not convenient for adjusting the spacing of the adhesive application structure according to the different sizes of the friction pads. Therefore, there are certain shortcomings when using an adhesive application device to apply adhesive to friction pads. When applying adhesive to narrow friction pads, both sides of the friction pad will also be coated with adhesive, and the adhesive will overflow downwards into areas where adhesive is not needed. When applying adhesive to wide friction pads, the sides of the friction pad will not come into contact with the adhesive application structure, affecting the uniformity of adhesive application to the friction pads, and thus affecting the subsequent bonding of the friction pads. This reduces the flexibility and practicality of the adhesive application device to a certain extent.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing adhesive application equipment. Summary of the Invention

[0005] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different intelligent adhesive coating device for friction pad processing. This solution overcomes the shortcomings of the prior art, which necessitates adjusting the spacing of the adhesive coating structure according to the different sizes of the friction pads. Specifically, when applying adhesive to narrow friction pads, adhesive is applied to both sides, overflowing into areas where it is not needed. Conversely, when applying adhesive to wide friction pads, the sides do not come into contact with the adhesive coating structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent glue-applying device for friction plate processing, comprising a base, wherein the top middle area of ​​the base is connected by an electric push rod to a support plate for mounting auxiliary rollers and conveying rollers, wherein an adjustment structure for limiting the width of the friction plate and controlling the spacing of the cavity glue tubes is provided between the conveying rollers, wherein a glue tank for loading glue is connected to the top side of the base by several support columns, wherein a cavity glue tube is connected to the bottom of the glue tank by several sliders, and an infrared sensor for sensing the friction plate is installed at the bottom of the glue tank, wherein a glue delivery hose for conveying glue is connected between each cavity glue tube and the glue tank, wherein a set of triggering structures for adjusting the glue output is provided in each cavity glue tube, and a set of sealing structures for preventing glue leakage is installed at the lower end of the glue outlet of each cavity glue tube, and a connecting frame for adjusting and controlling the glue scraping thickness is connected to the bottom of the glue tank.

[0007] Preferably, a motor-driven conveying roller frame is installed at the top center of the bearing plate, and the rollers of the conveying roller frame are covered with a rubber layer that increases the friction force for conveying the friction plate. In addition, two sets of adjustable height auxiliary roller frames are provided on each side of the top of the bearing plate to assist in the arc-shaped conveying of the friction plate.

[0008] Preferably, the piston plate of the glue tank is connected to a counterweight that applies stable pressure to the glue by passing through the top of the glue tank via a connecting rod.

[0009] Preferably, the triggering structure includes a fixed horizontal plate, a spring telescopic rod, a sealing ball, a trigger block, a trigger rod, and an annular flow limiting block. A fixed horizontal plate for supporting two sets of spring telescopic rods is fixedly connected to the inner wall of each hollow tube, and the lower end of each set of spring telescopic rods is connected to the sealing ball. A trigger rod for pushing the trigger block is slidably connected to the outer wall of each hollow tube, and the inclined outer wall of each trigger block is in contact with the outer wall of the sealing ball. An annular flow limiting block for cooperating with the sealing ball to limit the flow is fixedly connected to the bottom of the inner wall of each hollow tube, and the inner wall of each annular flow limiting block is provided with protrusions at equal angles to prevent complete contact with the sealing ball.

[0010] Preferably, the sealing structure includes a sealing plate, a full gear, a T-shaped gear, and a return spring. The lower end of each hollow tube is connected to a sealing plate that fits the outlet via a connecting shaft. The end of the connecting shaft penetrates the outer wall of the hollow tube and is connected to a T-shaped gear via the full gear. The upper end of each T-shaped gear is engaged and slidably connected to the outer wall of the hollow tube. A return spring for connecting the hollow tube is nested on the outer wall of each T-shaped gear, and the lower end of each T-shaped gear is rotatably connected to an arc-shaped area.

[0011] Preferably, the adjustment structure includes a bidirectional threaded shaft, a limiting plate, and a limiting rod. The top of the conveying roller frame is rotatably connected to a bidirectional threaded shaft with a thread density that increases from sparse to dense from the outside to the inside. Each end of the bidirectional threaded shaft is threaded to a limiting plate for limiting the two sides of the friction plate and adjusting the spacing of the cavity hose. The upper ends of the conveying roller frame are fixedly connected to a limiting rod for penetrating the limiting plate. Each limiting plate has a roller group inside it to facilitate contact with the two sides of the friction plate for auxiliary conveying.

[0012] Preferably, a scraper for spreading the glue evenly is provided between the connecting frames, and the scraper and the connecting frames are respectively rotatably and threadedly connected by a manual screw for adjusting the up and down movement of the scraper to control the thickness of the glue.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The intelligent glue application device for friction plate processing, according to the different widths of the friction plates, manually rotates the bidirectional threaded shaft in conjunction with the limiting rod to limit the two limiting plates to move closer to each other, so that the conveying rollers on the inner side of the two limiting plates are in contact with the edge of the friction plate, thereby achieving the effect of positioning the friction plate. At the same time, the movement of the two limiting plates drives the hollow rubber tubes on both sides to move towards the middle. The auxiliary spring between the sliders helps to move the remaining hollow rubber tubes towards the middle, so that the spacing between each hollow rubber tube is relatively uniform, which facilitates the subsequent uniform and even glue application. Because the limiting plates limit the outermost two hollow rubber tubes, the glue of the glue application structure on both sides is prevented from being applied to the edge area of ​​the friction plate, which would cause the glue to flow to the two sides of the friction plate, resulting in glue waste, affecting the uniformity of glue application, and contaminating the areas that are not to be glued.

[0014] The friction pads are conveyed to the side away from the bidirectional threaded shaft by the conveyor roller frame. With the help of auxiliary roller frames of different heights, the friction pads are conveyed and coated in an arc shape. This ensures that the inner wall of the arc-shaped friction pad and the glue outlet end of the cavity glue tube are always kept at the same distance, which facilitates stable and uniform glue coating on the inner wall of the friction pad.

[0015] When the friction plate is coated with adhesive, the contact and compression of the arc-shaped area pushes the T-shaped toothed rod upward, and the return spring is compressed. At the same time, during the upward movement of the T-shaped toothed rod at the lower end of each cavity tube, the outer wall tooth block drives the meshing full gear to rotate, thereby driving the sealing plate in the glue outlet at the lower end of the cavity tube to rotate and open through the connecting shaft, allowing the adhesive in the cavity tube to flow out and coat the friction plate. When the end of the friction plate disengages from the arc-shaped area on the cavity tube, the return spring pushes the T-shaped toothed rod downward, driving the full gear to reverse. Through the connecting shaft, the sealing plate rotates and fits against the inner wall of the glue outlet to prevent glue leakage.

[0016] When the device applies adhesive from one end of the arc-shaped friction plate to the other end, the friction plate is conveyed in an arc shape. At this time, the end of the friction plate is close to the infrared sensor, which will cause the infrared sensor to capture the signal and transmit it to the control device. This will control the motor to stop conveying the friction plate, making it easier to remove the coated friction plate. This achieves the purpose of intelligent conveying of the friction plate for adhesive application.

[0017] When adjusting the spacing of the cavity tubes to apply adhesive to friction plates of different widths, it is necessary to control the amount of adhesive dispensed from each cavity tube while keeping the number of cavity tubes constant. This ensures that the cavity tubes can evenly apply adhesive to friction plates of different widths, avoiding situations where narrower friction plates are coated with too much adhesive or wider friction plates are coated with too little adhesive. This improves the practicality of the device and the intelligence of its adaptive adjustment. Attached Figure Description

[0033] The adjustment structure 12 includes a bidirectional threaded shaft 1201, a limiting plate 1202, and a limiting rod 1203. The top of the conveying roller frame 3 is rotatably connected to the bidirectional threaded shaft 1201 with a thread density that increases from sparse to dense from the outside to the inside. Each end of the bidirectional threaded shaft 1201 is threaded to a limiting plate 1202 for limiting the two sides of the friction plate and adjusting the spacing of the cavity hose 7. The upper ends of the conveying roller frame 3 are fixedly connected to a limiting rod 1203 for passing through the limiting plate 1202. Each limiting plate 1202 is provided with a roller group inside to facilitate contact with the two sides of the friction plate for auxiliary conveying.

[0034] A scraper plate 1302 for spreading glue evenly is provided between the connecting frames 13, and a manual screw 1301 for adjusting the up and down movement of the scraper plate 1302 to control the glue thickness is rotatably and threadedly connected to the connecting frames 13.

[0035] Working Principle: First, the device is placed in the working area. An electric push rod moves the support plate 4 and the components it supports upwards to the appropriate height for the friction pad thickness. This allows the friction pad to be closer to the glue outlet at the lower end of the cavity tube 7 during glue application. Depending on the width of the friction pad, the bidirectional threaded shaft 1201 is manually rotated in conjunction with the limiting rod 1203, causing the two limiting plates 1202 to move closer together. This brings the conveying rollers inside the two limiting plates 1202 into contact with the edge of the friction pad, achieving the effect of positioning the friction pad. Simultaneously, the movement of the two limiting plates 1202 moves the cavity tubes 7 on both sides towards the center. The auxiliary spring between the sliders 6 assists in moving the remaining cavity tubes 7 towards the center. With the help of the auxiliary spring, each cavity... The spacing between the tubing 7 is relatively uniform. As the hollow tubing 7 approaches each other, it will contact and push the trigger rod 1005 and trigger block 1004 to move into the hollow tubing 7. This causes the trigger block 1004 to move while its inclined surface squeezes the sealing ball 1003, causing the spring telescopic rod 1002 to be stretched. The sealing ball 1003 moves downward and approaches the annular flow limiting block 1006. This, in conjunction with the inclined inner wall of the annular flow limiting block 1006, reduces the flow rate of adhesive, facilitating subsequent uniform and evenly spaced adhesive application. Because the limiting plate 1202 limits the outermost two hollow tubing 7, it prevents the adhesive from being applied to the edge area of ​​the friction plate, thus avoiding adhesive flowing to the sides of the friction plate, wasting adhesive, and affecting the uniformity of adhesive application. Without contaminating the adhesive application area, place one end of the friction pad to be coated onto the conveyor rollers of the conveyor roller frame 3, adhering it to the rubber layer. The rubber layer increases friction with the friction pad, improving stability during transport. The auxiliary roller frames 2, at different heights on both sides, facilitate the placement of the arc-shaped friction pad near the hollow rubber tube 7, and also provide positioning and limiting effects. Start the motor, and the conveyor roller frame 3 transports the friction pad away from the bidirectional threaded shaft 1201. The different heights of the auxiliary roller frames 2 ensure the friction pad is transported and coated in an arc shape, maintaining the same distance between the inner wall of the arc-shaped friction pad and the adhesive outlet end of the hollow rubber tube 7. This facilitates stable and uniform adhesive coating of the inner wall of the friction pad. During adhesive coating of the friction pad, through… The conveying roller frame 3, with its end contacting the lower arc-shaped area of ​​the hollow rubber tube 7, pushes the T-shaped toothed rod 1103 upward by contacting and squeezing the arc-shaped area. The return spring 1104 is compressed by force. At the same time, during the upward movement of the T-shaped toothed rod 1103 at the lower end of each hollow rubber tube 7, its outer wall tooth blocks drive the meshing full gear 1102 to rotate, thereby driving the sealing plate 1101 in the glue outlet at the lower end of the hollow rubber tube 7 to rotate and open through the connecting shaft, allowing the glue in the hollow rubber tube 7 to flow out and apply glue to the friction plate. When the device applies glue from one end of the arc-shaped friction plate to the other end, because the friction plate is conveyed in an arc shape, the end of the friction plate is close to the infrared sensor 8, which will cause the infrared sensor 8 to capture a signal and transmit it to the control device, controlling the motor to stop conveying the friction plate.This system facilitates the removal of the pre-coated friction pads, achieving intelligent conveying of the friction pads for adhesive application. It eliminates the need for manual conveying of the friction pads, which is time-consuming, labor-intensive, and results in inconsistent conveying speeds that affect the adhesive application outcome.

[0036] When the end of the friction plate disengages from the arc-shaped area on the cavity tube 7, the return spring 1104 pushes the T-shaped toothed rod 1103 to move down, causing the full gear 1102 to reverse. Through the connecting shaft, the sealing plate 1101 rotates and fits against the inner wall of the glue outlet to prevent glue leakage.

[0037] The counterweight continuously applies downward pressure to the piston plate via the connecting rod, causing the piston plate to exert a constant downward force on the glue in the glue tank 5. This causes the glue to be continuously delivered through several glue delivery hoses 9 into the cavities within the cavity glue tubes 7. Since the application of glue to friction plates of different widths requires adjustment of the spacing of the cavity glue tubes 7, while keeping the number of cavity glue tubes 7 constant, it is necessary to control the glue output of each cavity glue tube 7. This facilitates the uniform application of glue to friction plates of different widths by the cavity glue tubes 7, avoiding situations where narrower friction plates are coated with too much glue or wider friction plates are coated with too little glue. This improves the practicality and adaptive adjustment intelligence of the device. This is the working principle of the intelligent glue application device for friction plate processing.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
