Description

Technical Field

[0001] This utility model relates to a method for producing automotive brake components, and more particularly to a disc brake pad adhesive applicator. Background Technology

[0002] Currently, in the production process of automotive brake pads, adhesive is first rolled onto the pressing surface of the steel backing plate using a roller glue machine. The rolled-up steel backing plate is then baked in a tunnel baking machine. Finally, the baked steel backing plate is placed on a pressing device, where powder is pressed onto the pressing surface of the steel backing plate, thus forming the friction pad. However, the existing roller glue machine tends to roll adhesive from one edge of the steel backing plate to the other during the rolling process. Since the friction pad is typically located in the center of the steel backing plate, this not only wastes adhesive but can also cause adhesion at the edges. Therefore, it is necessary to design a disc brake pad adhesive applicator that can fully utilize the adhesive and prevent the edges of the steel backing plate from sticking to other objects. Utility Model Content

[0003] The purpose of this utility model is to provide a disc brake pad adhesive applicator that can fully utilize the adhesive and prevent the steel backing plate edge from sticking to other objects.

[0004] Technical solution: The disc brake pad glue applicator of this utility model includes a control box, a transport unit, a glue storage mechanism, a position sensor, a glue applicator unit, and a lifting drive mechanism;

[0005] The glue storage mechanism is installed above the transport unit. It stores the glue, stirs it, and maintains its temperature. The transport unit horizontally transports each steel backplate. The glue application unit is installed below the glue storage mechanism via a lifting drive mechanism. The lifting drive mechanism drives the glue application unit to move up and down, so that the glue application unit presses against the pressing surface of the steel backplate to release the glue. The glue storage mechanism delivers the glue to the glue application unit. A position sensor is installed on the transport unit to detect whether the steel backplate has reached below the glue application unit. The transport unit, glue storage mechanism, position sensor, and lifting drive mechanism are all driven and controlled by a control box.

[0006] Furthermore, the adhesive application unit includes a unit box, a bottom shell, a cushioning layer, and various release components; the lifting drive mechanism includes a lifting drive motor, a lifting drive shaft, two drive discs, two push-pull connection units, and four support columns; the four support columns are all vertically fixed on the transport unit, and four guide protrusions are provided on the side of the unit box, with the four support columns slidingly passing through the four guide protrusions respectively; the cushioning layer is laid inside the unit box, and the top of the unit box is connected to the adhesive storage mechanism via a hose; a release window is provided at the bottom of the unit box; the bottom shell is detachably installed on the bottom of the unit box, and a protrusion is provided on the upper side of the bottom shell; The platform extends into the release window, and a sealing ring is provided between the platform and the release window; a groove is provided on the platform, and each release component is installed through the bottom of the groove, releasing the glue downwards; the lifting drive shaft is rotatably mounted on the glue storage mechanism, and the lifting drive motor is used to drive the lifting drive shaft to rotate; two drive discs are respectively fixed on both ends of the lifting drive shaft, and the upper ends of the two push-pull connecting units are rotatably mounted on the edges of the two drive discs at the same positions, and the lower ends of the two push-pull connecting units are rotatably mounted on the side of the unit box, and the length of the push-pull connecting units is adjustable; the lifting drive motor is driven and controlled by the control box.

[0017] The glue storage mechanism is installed above the transport unit. It stores the glue, stirs it, and maintains its temperature. The transport unit horizontally transports each steel back plate. The glue application unit is installed below the glue storage mechanism via a lifting drive mechanism. The lifting drive mechanism drives the glue application unit to move up and down, so that the glue application unit presses against the pressing surface of the steel back plate to release the glue. The glue storage mechanism delivers the glue to the glue application unit. The position sensor 24 is installed on the transport unit to detect whether the steel back plate has reached below the glue application unit. The transport unit, glue storage mechanism, position sensor 24, and lifting drive mechanism are all driven and controlled by the control box 16.

[0018] Furthermore, the transport unit includes a conveyor drive motor 3, two conveyor strips 1, two conveyor timing belts 5, and two conveyor support shafts 4; the two conveyor support shafts 4 are rotatably installed between the two ends of the two conveyor strips 1, and two timing pulleys 23 are fixedly installed on each of the two conveyor support shafts 4; support legs 2 are vertically fixedly installed below the two ends of the two conveyor strips 1; the two conveyor timing belts 5 are respectively wound around the two timing pulleys 23 at corresponding positions on the two conveyor support shafts 4; the conveyor drive motor 3 is fixedly installed on one support leg 2 and drives the rotation of one conveyor support shaft 4 through a sprocket transmission mechanism; each positioning unit is installed on the two conveyor timing belts 5, and each positioning unit consists of two positioning rods 6, used to limit the position of each steel back plate; a pressing support plate 25 is provided between the two conveyor strips 1 and below the glue application unit, and the pressing support plate 25 is close to the upper layer of the two conveyor timing belts 5 for support; a position sensor 24 is installed on the pressing support plate 25.

Inside the unit 7, a sealing ring 29 is provided between the boss 28 and the release window 27 to enhance the sealing performance at the installation position; a groove 30 is provided on the boss 28, and each release component is installed through the bottom of the groove 30 to release the glue downward; the lifting drive shaft is rotatably mounted on the glue storage mechanism through the rotating shaft support 20, and the lifting drive motor 21 is used to drive the lifting drive shaft to rotate; two drive discs 22 are respectively fixed on both ends of the lifting drive shaft, and the upper ends of the two push-pull connection units are rotatably mounted on the edges of the two drive discs 22 at the same position, and the lower ends of the two push-pull connection units are rotatably mounted on the side of the unit box 9, and the length of the push-pull connection unit is adjustable; the lifting drive motor 21 is driven and controlled by the control box 16. The detachable mounting base 10 can be replaced with steel back plates of different sizes to meet the gluing requirements of different areas. The filling of the buffer cotton layer 26 can slow down the flow rate of the glue and control the amount of glue released downward by the release component. The unit box 9 is lifted and pulled by two drive discs 22 and two push-pull connecting units, so that the gluing position is limited to the middle area of ​​the steel back plate, instead of rolling from one edge to the other like a roller glue machine. This reduces glue waste and also prevents the edge of the steel back plate from sticking to other objects.

[0020] Furthermore, the glue storage mechanism includes a storage box 11, a cover plate 14, a stirring drive motor 13, and a heating element; the storage box 11 is fixedly installed on four supporting columns 7, and the cover plate 14 covers the top opening of the storage box 11; a flexible hose 15 connects to the bottom of the storage box 11; the stirring drive motor 13 is installed on the cover plate 14, and a stirring rod extending into the storage box 11 is installed on the output shaft of the stirring drive motor 13, thereby ensuring uniform mixing of the glue and uniform heating; the heating element is fixedly installed on the cover plate 14, and the heating end extends into the storage box 11; an electrode protective cover 12 for the heating element is provided on the cover plate 14 to enhance electrical safety; the stirring drive motor 13 and the heating element are both driven and controlled by a control box 16.

[0021] Furthermore, the release assembly includes a release tube 31, a release rod 33, a tension spring 34, and a cap 35; the release tube 31 is installed through the bottom of the groove 30, and a cross-shaped bracket 32 ​​is provided near the lower end of the release tube 31; the lower end of the release rod 33 movably passes through the center of the cross-shaped bracket 32, and the upper end is fixed to the cap 35; the tension spring 34 is sleeved on the release rod 33, and the upper end of the tension spring 34 is fixed to the cap 35, and the lower end is fixed to the cap 35. On the T-shaped bracket 32, a cap 35 is used to pull the cap 35 to cover the upper end of the release tube 31, and to make the lower end of the release rod 33 extend out of the lower end of the release tube 31. The lower side of the cap 35 is set as a concave arc-shaped top 36, so that under the pull of the tension spring 34, the glue can be pushed down into the release tube 31 and released onto the steel back plate. At the same time, after rising to a certain height, the cap 35 will cover the upper end of the release tube 31, thereby preventing the glue from flowing down the release tube 31.

[0022] Furthermore, the push-pull connection unit includes an internally threaded tube 17, two connecting screws 18, and two locking nuts 19. The two connecting screws 18 are screwed onto the upper and lower ends of the internally threaded tube 17, respectively, with opposite thread directions. The two locking nuts 19 are screwed onto the two connecting screws 18 and press against the upper and lower ends of the internally threaded tube 17 to achieve locking and fixation. The threaded engagement depth of the two connecting screws 18 is adjusted, thereby adjusting the length of the push-pull connection unit and adjusting the descent distance of the bottom shell 10 to meet the adhesive application requirements of steel back plates of different thicknesses.

[0023] Furthermore, the control box 16 is installed on the storage box 11 and is equipped with a controller, a button panel, a display screen, a conveying drive circuit, a lifting drive circuit, a stirring drive circuit, and an electric control switch. The controller is electrically connected to the temperature sensor, the position sensor 24, the button panel, the display screen, the conveying drive circuit, the lifting drive circuit, the stirring drive circuit, and the electric control switch. The conveying drive circuit, the lifting drive circuit, and the stirring drive circuit are electrically connected to the conveying drive motor 3, the lifting drive motor 21, and the stirring drive motor 13, respectively, thereby realizing the controller's drive control of the conveying drive motor 3, the lifting drive motor 21, and the stirring drive motor 13. The electric control switch is connected in series in the power supply line of the heating element, and the controller controls the on / off power of the heating element through the electric control switch, thereby cooperating with the temperature sensor to achieve glue temperature control within the set temperature range. The above circuits and their controls all adopt existing technology and are not the innovation of this utility model.

[0024] When using the disc brake pad glue applicator disclosed in this utility model, the worker sets the glue temperature as needed through the button panel and display screen. After starting, the controller obtains the temperature value from the temperature sensor and then uses the electric control switch to provide feedback control to the heating element, so that the glue temperature is controlled within the set temperature range. At the same time, the controller also drives the stirring drive motor 13 through the stirring drive circuit to achieve the stirring of the glue.

[0025] When the controller detects that the steel back plate has reached below the bottom shell 10 through the position sensor 24, it stops the conveying drive motor 3 through the conveying drive circuit, so that the steel back plate stays below the bottom shell 10. Then, the lifting drive motor 21 is controlled by the lifting drive circuit to make the glue application unit move down. After the lower end of the release rod 33 of the release component contacts the steel back plate, it pushes the cap 35 to move up, and the glue enters the release tube 31. After the bottom shell 10 continues to move up, the cap 35 pushes the glue down under the action of the tension spring 34 and releases it from the lower end of the release tube 31 onto the steel back plate, thus realizing the glue application of the steel back plate.

[0026] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
