Description

Technical Field

[0001] This invention relates to the field of brake pad production equipment technology, specifically a brake pad steel backing adhesive spraying device. Background Technology

[0002] Brake pads, also known as brake linings, are the most critical safety component in a car's braking system. The effectiveness of braking depends entirely on the brake pads; therefore, good brake pads are considered the guardians of both people and vehicles. 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 heat-insulating layer is made of a non-heat-conducting material for heat insulation. The friction blocks are composed of friction materials and adhesive. During braking, they are pressed against the brake disc or brake drum to generate friction, thereby achieving the purpose of slowing down the vehicle. Due to friction, the friction blocks will gradually wear down; generally speaking, the lower the cost of the brake pads, the faster they wear out.

[0003] Currently, during the production of brake pads, the surfaces where the steel backing and friction material are bonded need to be coated with adhesive to ensure a strong bond during the subsequent hot pressing process. However, existing adhesive application methods include manual application and adhesive application equipment. Manual application is gradually being replaced by adhesive application equipment due to its high labor intensity and low production efficiency. Current adhesive application equipment includes a transmission mechanism and adhesive spraying and drying equipment arranged in series on the transmission mechanism. The steel backing is transported through the transmission mechanism and passes through the adhesive spraying and drying equipment in sequence to achieve adhesive application and drying. This assembly line-style adhesive application equipment generally occupies a large area and therefore cannot meet current usage requirements. Therefore, we propose a new adhesive application equipment. Summary of the Invention

[0013] The material receiving platform is provided with multiple sets of material receiving slots. A material receiving block is fixedly connected to the bottom of the material receiving platform on one side of the material receiving slot. A set of limiting platforms is provided at the bottom of the material receiving platform corresponding to each set of material receiving slots in a vertical column. Both ends of the multiple sets of limiting platforms are fixedly connected to a sliding platform. When the material receiving platform is located in the outside, the two sides of the material receiving platform are slidably connected to the unloading frame.

[0015] In the above technical solution, the drive motor is fixedly connected to the outside of the outer casing, and a first transmission shaft is fixedly connected to the power output shaft of the drive motor. The other end of the first transmission shaft is fixedly connected to the shaft rod.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The present invention can drive the material-bearing mechanism to perform linear motion through the linear motion mechanism. When the material-bearing mechanism holds the steel back and moves into the outer casing, the glue-spraying mechanism can spray glue onto the steel back. When the material-bearing mechanism continues to move inward, the sprayed glue can be dried by the drying mechanism. The overall structure of the device is compact, which is different from the existing assembly line equipment and occupies a smaller area.

[0024] 2. The present invention uses a linear motion mechanism to drive the material receiving platform to pass through the material inlet. When the sliding platform on the material receiving platform comes into contact with the pressure block, the pressure block can press down on the sliding platform, thereby compressing the elastic element. At this time, the limiting platform at the bottom of the material receiving platform is displaced, thereby releasing the supporting effect of the limiting platform on the steel back, so that the steel back falls due to its weight, thereby achieving the effect of unloading. This unloading method can speed up the unloading speed under the above advantages, thereby increasing production efficiency.

[0025] 3. This invention can drive multiple sets of fan blades to rotate via a drive motor. At the same time, the drive motor can also drive the lead screw to rotate. The linear motion mechanism and the fan blades share a drive motor, which can greatly reduce energy consumption, thereby saving energy and reducing emissions. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0033] Please see Figure 1 —4, a brake pad steel back adhesive spraying device, including an outer shell 1, a linear motion mechanism, a material receiving mechanism, an adhesive spraying mechanism and a drying mechanism. The outer shell 1 is provided with an adhesive storage chamber 2, a central chamber and a processing chamber 3. The adhesive storage chamber 2 is used to store adhesive, and a liquid filling pipe is provided on the outer shell 1 in communication with the adhesive storage chamber 2. A material port 4 is provided on one side of the outer shell 1 in communication with the processing chamber 3. The central chamber is further divided into a pump chamber 5 and an air duct chamber 6. The linear motion mechanism and the material receiving mechanism are located in the processing chamber 3, and the drying mechanism is located in the air duct chamber 6. The adhesive spraying mechanism includes a pump 7, a nozzle 8 and a pipeline 9. The pump 7 is fixedly connected in the pump chamber 5, and the nozzle 8 is fixedly connected in the processing chamber 3 and close to the material port 4. The pump 7, the nozzle 8 and the adhesive storage chamber 2 are connected by the pipeline 9.

[0034] The aforementioned linear motion mechanism includes a motion frame 10, a base 11, and a lead screw 12. The base 11 is fixedly connected inside the processing chamber 3. A motion slide 13 is provided on the base 11. The motion frame 10 is slidably connected to the motion slide 13. The lead screw 12 is threadedly connected to the bottom of the base 11. The lead screw 12 is powered by a drive motor 14, so that the drive motor 14 can drive the lead screw 12 to rotate, thereby causing the motion frame 10 to perform linear motion on the motion slide 13. The material receiving mechanism is fixedly connected to the motion frame 10, so that the linear motion mechanism drives the material receiving mechanism to perform linear motion, thereby enabling the material receiving mechanism to pass out of the outer cover 1 from the material port 4 or enter the outer cover 1 from the material port 4. When the linear motion mechanism drives the material receiving mechanism to move into the outer cover 1, the pump 7 can draw the adhesive in the adhesive storage chamber 2 to the nozzle 8 for spraying, thereby spraying the adhesive onto the steel back held by the material receiving mechanism.

[0035] A feeding rack 15 is fixedly connected to the outer wall of the outer casing 1 corresponding to the material inlet 4. The aforementioned material-bearing mechanism includes a material-bearing platform 16, an elastic element 17, and a limiting platform 18. The material-bearing platform 16 is fixedly connected to the motion frame 10 and corresponds to the material inlet 4. Sliding grooves 19 are provided on both sides of the material-bearing platform 16. The end of the sliding groove 19 near the material inlet 4 is an open structure. A sliding strip 20 is fixedly connected to one side of the sliding groove 19. A groove is provided on the sliding table 40 corresponding to the sliding strip 20. The sliding strip 20 is slidably connected in the groove, so that the sliding table 40 can slide in the sliding groove 19 without falling off. A pressure block 21 is fixedly connected to each set of sliding tables 40 on the feeding rack 15. An elastic element 17 is fixedly connected in the sliding groove 19. The other end of the elastic element 17 is fixedly connected to the sliding table 40, so that when the linear motion mechanism drives the material-bearing platform 16 to move out of the outer casing 1, the pressure block 21 can press down on the sliding table. 40, thereby compressing the elastic element 17. Furthermore, the material receiving platform 16 is provided with multiple sets of material receiving slots 22. The bottom of the material receiving platform 16 is fixedly connected to one side of the material receiving slot 22 with a material receiving block 23. The bottom of the material receiving platform 16 is provided with a set of limiting platforms 18 corresponding to each set of longitudinal material receiving slots 22. The limiting platforms 18 and the material receiving blocks 23 can support the steel back, so that the steel back can be placed in the material receiving slot 22 without falling off. The two ends of the multiple sets of limiting platforms 18 are fixedly connected to the sliding platform 40. When the sliding platform 40 is pressed down by the pressure block 21 and displaced, the limiting platforms 18 can be displaced, and then the limiting platforms 18 will release the support of the steel back, causing the steel back to fall off, thereby realizing the unloading of the steel back. Furthermore, when the material receiving platform 16 is located in the outside, the two sides of the material receiving platform 16 are slidably connected to the unloading frame 15, so as to ensure that the material receiving platform 16 remains stable and does not shake after passing through the outside.

[0036] The aforementioned drying mechanism includes a heating device 24, a mounting platform 25, and fan blades 26. An air inlet 27 is provided on the outer casing 1, communicating with the air duct cavity 6. The mounting platform 25 is fixedly connected inside the air duct cavity 6, and the mounting platform 25 has multiple sets of mounting ports. Each set of mounting ports is rotatably connected to a fan blade 26, and each set of fan blades 26 is fixedly connected to a shaft 28. The multiple sets of shafts 28 are dynamically connected, with one set of shafts 28 being dynamically connected to a drive motor 14. When the drive motor 14 drives the corresponding shaft 28 to rotate, all sets of shafts 28 will rotate, thereby driving the multiple sets of fan blades 26 to rotate via the drive motor 14. The heating device 24 is also fixedly connected inside the air duct cavity 6. Multiple air outlets 29 are provided on the bottom surface of cavity 6, which is connected to processing cavity 3. When the material receiving mechanism moves into the outer cover 1, the drive motor 14 drives the fan blades 26 to rotate in the forward direction, which can draw outside air into the air duct and blow it towards the material receiving mechanism. At this time, the heating device 24 heats the air and blows the hot air towards the material receiving mechanism, thereby drying the adhesive on the steel back. When the material receiving mechanism moves out of the outer cover 1, the drive motor 14 changes the rotation direction and rotates in the reverse direction. At this time, the fan blades 26 can change the direction of gas flow, and the heating device 24 stops working. This can exhaust the hot air in processing cavity 3 to the outside, thereby avoiding the accumulation of heat in processing cavity 3, which would cause the adhesive in the nozzle 8 to solidify and cause the nozzle 8 to become blocked.

[0037] Based on the above embodiments, further, a set of drive motors 14 is selected. The drive motors 14 are fixedly connected to the outside of the outer casing 1. A first transmission shaft 30 is fixedly connected to the power output shaft of the drive motor 14. The other end of the first transmission shaft 30 is fixedly connected to the shaft 28, so that the drive motor 14 can drive the fan blades 26 to rotate. A second transmission shaft 31 is fixedly connected to one end of the lead screw 12 near the drive motor 14. The second transmission shaft 31 extends out of the outer casing 1. A first pulley 32 is fixedly connected to the first transmission shaft 30, and a second pulley 33 is fixedly connected to the second transmission shaft 31. The first pulley 32 and the second pulley 33 are connected by a transmission belt 34, and the transmission ratio between the first pulley 32 and the second pulley 33 is higher than that of the first pulley 32. For example, the first pulley 32 rotates ten times while the second pulley 33 rotates one time, thus meeting the high-speed rotation requirements of the fan blades and the slow rotation of the lead screw. In this way, when the drive motor 14 drives the fan blades 26 to rotate, it can also drive the lead screw to rotate. When the lead screw 12 rotates and moves the material-bearing mechanism into the outer casing 1, the fan blades 26 rotate in the forward direction. When the lead screw 12 rotates and moves the material-bearing mechanism out of the outer casing 1, the fan blades 26 rotate in the reverse direction. By setting up a set of drive motors 14, the number of motors can be reduced, thereby reducing energy consumption, achieving energy saving and emission reduction, and also reducing the failure rate. Furthermore, a protective cover 35 is fixedly connected to the outer casing 1, and the first pulley 32 and the second pulley 33 are both located inside the protective cover 35, thereby protecting the power components.

[0038] In this embodiment, a conveyor belt mechanism 39 is provided at the bottom of the unloading rack. After the material receiving mechanism unloads the steel backing coated with adhesive, the conveyor belt mechanism 39 can transport the steel backing to the next process.

[0039] Please see Figure 5 This embodiment also provides a structure for the elastic element 17:

[0040] The elastic element 17 includes an outer cylinder 36, a sliding column 37, and a spring 38. A sliding cavity is provided inside the outer cylinder 36. The sliding column 37 is slidably connected inside the sliding cavity. The spring 38 is fixedly connected to the bottom of the sliding cavity. The other end of the spring 38 is fixedly connected to the sliding column 37. The outer cylinder 36 is fixedly connected to the groove wall of the sliding groove 19. The sliding column 37 is fixedly connected to the sliding table 40.

[0041] In summary, this embodiment discloses a brake pad steel backing adhesive spraying device, which is used to apply adhesive to the brake pad steel backing. Specifically, the adhesive-coated surface of the steel backing is placed in the material receiving groove 22 with the adhesive side facing up. The steel backing is supported by the limiting platform 18 and the material receiving block 23. The steel backing can be placed manually or by a robotic arm. After placement, the drive motor 14 drives the lead screw 12 to rotate, thereby causing the motion frame 10 to move the material receiving platform 16 from the material outlet 4 into the outer casing 1. When the pump 7 operates, it draws the adhesive from the adhesive storage chamber 2 to the nozzle 8 for spraying. As the receiving platform 16 moves inward, the adhesive sprayed from the nozzle 8 is sprayed onto the steel back. At the same time, the drive motor 14 drives the fan blades 26 to rotate and generate wind. The heating device 24 heats the air and generates heat, causing the fan blades 26 to blow hot air out from the air outlet 29, thereby drying the sprayed steel back. When the receiving platform 16 moves to its end, the adhesive spraying and drying of the steel back are completed.

[0042] Then, the drive motor 14 changes its rotation direction. At this time, the motion frame 10 drives the material receiving platform 16 to move outward from the material inlet 4. At this time, the pump 7 and the heating device 24 stop working. The drive motor 14 drives the fan blade 26 to change its rotation direction. At this time, the hot air in the processing chamber 3 is discharged. When the material receiving platform 16 passes through the material inlet 4, the pressure block 21 presses down on the sliding table 40. At this time, the sliding table 40 drives the limiting table 18 to move, so that the limiting table 18 can no longer support the steel back. At this time, the steel back falls from the material receiving groove 22 and is transferred to the next process on the conveyor belt mechanism 39. Then, the linear motion mechanism drives the material receiving platform 16 to move a certain distance towards the outer cover 1, so that under the action of the elastic element 17, the limiting table 18 returns to its original position. At this time, the steel back can be placed again and the above process can be repeated.
