Abstract
Description
Technical Field
[0001] This utility model relates to the field of brake pad adhesive application technology, and in particular to an adhesive applicator. Background Technology
[0002] Automotive brake pads, also known as brake linings, are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The friction linings and friction blocks withstand external pressure, generating friction to achieve vehicle deceleration. Automotive brake pads generally consist of a steel plate, an adhesive heat-insulating layer, and friction blocks. The steel plate is coated to prevent rust, and the coating process uses an SMT-4 oven temperature tracker to monitor temperature distribution and ensure quality.
[0003] During the brake pad manufacturing process, steel plates and friction blocks are usually bonded together to ensure the normal use of the brake pads. Currently, existing adhesive applicators typically use only one type of adhesive nozzle to spray the steel plate during the adhesive application process. Although this can make the steel plate sprayed more evenly, the edges of the friction blocks wear more severely in actual use. Therefore, a thicker layer of adhesive needs to be applied to the edges to improve the quality of the brake pads and increase safety. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.
[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0025] Example 1: Please refer to Figures 1-6 The illustrated adhesive applicator includes a base plate 1, with a bracket 2 mounted on top of the base plate 1. Both the base plate 1 and the bracket 2 are made of high-strength 6061-T6 aluminum alloy, combining lightweight and deformation resistance. A sliding plate 4 is slidably connected above the base plate 1, and the sliding plate 4 is made of wear-resistant cast iron HT250. A drive component 3 is mounted at the bottom of the base plate 1 to drive the sliding plate 4. The drive component 3 is driven by a servo motor (750W power) through a synchronous belt drive (transmission ratio 1:2). An encoder provides real-time position feedback, with a repeatability accuracy of ±0.02mm, ensuring precise alignment of the brake pads. The device also includes an adhesive applicator 5 mounted on the base plate 1 and the bracket 2, used for applying adhesive to the brake pads; and a replacement component 6 mounted on the adhesive applicator 5, used for replacing the adhesive applicator head.
[0026] Furthermore, the adhesive application component 5 includes a suction pump 7 mounted on the base plate 1. The input end of the suction pump 7 is fixedly connected to a storage box 8, which is used to store adhesive. The storage box 8 is mounted on the base plate 1. The output end of the suction pump 7 is fixedly connected to a hose 9. The storage box 8 and the hose 9 are made of food-grade PVC material, which is resistant to chemical corrosion from adhesive. The hose 9 extends through and into the interior of the bracket 2.
[0027] Furthermore, a cylinder 10 is installed at the bottom of the bracket 2, and a connecting plate 11 is fixedly connected to the output end of the cylinder 10. The connecting plate 11 has a hollow structure and adopts a T-shaped guide groove design inside (not shown in the figure) to reduce fluid resistance. A hollow disc 12 is installed at the bottom of the connecting plate 11 through the replacement component 6, and the top of the connecting plate 11 is fixedly connected to and communicates with the hose 9.
[0028] Please see Figure 2 Specifically: A shaped tube 13 is installed at the bottom of the hollow disc 12. It is formed by 3D printing technology according to the outline of the brake pad steel sheet, with an error of ≤0.05mm. The shaped tube 13 is consistent with the edge shape of the steel sheet. Nozzles 14 are evenly installed at the bottom of the shaped tube 13. The bottom nozzle array 14 is distributed in a fan shape, and the coverage width matches the curvature of the steel sheet edge. A central nozzle 15 is evenly installed at the bottom of the hollow disc 12. The central nozzle 15 has multiple sets of atomizing nozzles (0.3mm orifice diameter) arranged in a ring. With the help of the Venturi effect, the glue is evenly atomized and sprayed. The cylinder 10 drives the connecting plate 11 to press down. The shaped tube 13 and the surface of the steel sheet maintain a gap of 0.5mm. The central nozzle 15 and the edge nozzles 14 work together to achieve simultaneous spraying of the top adhesive and the edge adhesive.
[0029] Example 2: This embodiment is a further explanation of Example 1, based on... Figures 1-6 As shown, it is worth noting that the replacement component 6 includes a fixing cylinder 16, which is fixedly installed at the bottom of the connecting plate 11. The fixing cylinder 16 has symmetrical slots 17, and springs 18 are installed inside both slots 17. The springs 18 are made of piano wire and are strengthened by heat treatment. The ends of the two springs 18 that are far apart from each other are fixedly connected to a locking block 19. The surface of the locking block 19 is plated with hard chrome to improve the biting strength and fatigue resistance.
[0030] Specifically, a connecting cylinder 20 is externally snapped onto the fixed cylinder 16. Both the fixed cylinder 16 and the connecting cylinder 20 are made of polyetheretherketone (PEEK) engineering plastic, which has high strength, high temperature resistance (260℃), and low friction characteristics, making it suitable for frequent insertion and removal operations. Both have through holes inside for adhesive to pass through. A sealing gasket 22 is provided at the joint between the connecting cylinder 20 and the fixed cylinder 16 to provide a seal and prevent adhesive leakage. The connecting cylinder 20 has a through groove 21 inside for the fixed cylinder 16 to be snapped into. The connecting cylinder 20 has a slot 23 inside that communicates with the through groove 21. Each slot 23 has a top post 25 inside. The ends of the two top posts 25 that are close to each other are fixedly connected to a top block 24. The ends of the two top posts 25 that are far apart from each other pass through the connecting cylinder 20 and are fixedly connected to a button 27. The button 27 is made of alloy material. Pressing the button 27 triggers the top post 25 to push the top block 24, and the locking block 19 compresses the spring 18 to unlock. After the old rubber head is taken out along the through groove 21, the new rubber head can be inserted for quick replacement.
[0031] Further reference Figure 2 - Figure 6 As shown, limiting sleeves 29 are symmetrically installed on the outside of the connecting cylinder 20. Limiting blocks 30 are fixedly connected inside each of the two limiting sleeves 29. Limiting posts 28 are fixedly connected to the outside of each of the two top posts 25. Magnets and iron plates are installed above the limiting blocks 30 and the limiting posts 28. Compression springs 26 are symmetrically fixedly connected to the outside of the connecting cylinder 20. The compression springs 26 facilitate the reset of the brake pad 27. The ends of the two compression springs 26 that are far apart from each other are fixedly connected to the button 27. After the replacement part 6 is replaced, the magnets and iron plates attract each other to prevent accidental activation of the button 27, thus improving the stability of the replacement part 6. The hollow disc 12 can be quickly replaced by replacing part 6, making it easier to adapt to different sizes of brake pads.
[0032] The principle behind this solution is as follows:
[0033] First, workers or robotic arms place steel sheets on the surface of sliding plate 4, and drive components 3 transport the steel sheets to the area directly below cylinder 10.
[0034] Secondly, the suction pump 7 delivers the glue from the storage box 8 to the inside of the connecting plate 11 through the hose 9, and then through the hollow disc 12 inside the channel machine. At the same time, the cylinder 10 drives the connecting plate 11 to press down, and the special tube 13 maintains a 0.5mm gap with the surface of the steel sheet. The center nozzle 15 and the edge nozzle 14 work together to achieve simultaneous spraying of the top adhesive and the edge adhesive.
[0035] Finally, when it is necessary to spray steel sheets of different sizes, turn button 27. Button 27 drives the top post 25 and the limiting post 28 to rotate, so that the limiting post 28 is disengaged from the limiting block 30. Press button 27 inward, so that the top post 25 drives the top 24 to squeeze the locking block 19, thereby disengaging the locking block 19 from the inside of the locking groove 23. Then pull the connecting cylinder 20 downward to disengage the connecting cylinder 20 from the fixing cylinder 16. Replace with a new hollow disc 12.
[0036] It should be noted that the drive unit 3, cylinder 10 and suction pump 7 are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
[0037] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
