Description

Technical Field

[0001] This invention relates to the field of brake pad backplate cleaning and surface coating technology, specifically to an automated equipment for cleaning and applying adhesive to brake pad backplates. Background Technology

[0002] Brake pad backing plates are a core component of automotive braking systems. Their surface cleanliness, adhesive application precision, and adhesive curing quality directly determine the bonding strength between the brake pad friction block and the backing plate, braking stability, and product lifespan.

[0003] Currently, most domestic brake pad manufacturers employ a production model that utilizes separate equipment, manual loading and unloading, and simple tooling for the backplate cleaning, adhesive application, and curing processes. This results in a low level of overall automation and integration, leading to numerous process defects and production pain points. 1. In the pre-loading process, existing equipment mostly involves manual placement of individual materials, resulting in small inventory capacity, low operating efficiency, and a lack of precise positioning and alignment structures. Problems such as offset, misalignment, and material jamming due to multiple material stacking are prone to occur during the conveying of back plates of different specifications, which cannot provide a regular and stable workpiece posture for subsequent dust removal and gluing processes.

[0004] 2. In the dust removal process, traditional equipment generally adopts a single-sided open-air blowing dust removal method, which can only clean the floating dust on the surface of the back plate. It is difficult to completely remove the firmly attached oxide debris and metal dust from the corners, inside and outside of the back plate, resulting in many dust removal dead corners. At the same time, the open-air dust removal structure causes metal dust to scatter freely, which not only causes dust pollution in the workshop, but also causes the scattered dust to re-adhere to the cleaned back plate surface, seriously affecting the cleanliness of the workpiece. In addition, the air pressure of traditional dust removal equipment is not adjustable, which cannot be adapted to the processing of back plates of different specifications and different dust adhesion levels. It is easy to cause thin back plates to be deformed by high-pressure airflow and thick dust back plates to be incompletely cleaned.

[0005] 3. In the glue application process, the industry generally uses manual glue application or simple fixed glue gun application, which lacks precise positioning and follow-up glue application structure. Manual glue application relies on the operator's experience and is prone to problems such as glue leakage, uneven glue layer thickness, and glue application position deviation. Simple glue guns cannot adapt to the different glue application contour requirements of multiple backplate models, and without a shielding and limiting structure, glue overflow can easily cause contamination of non-processed areas of the workpiece. At the same time, traditional tooling switching is cumbersome and requires the entire machine to be stopped to replace parts, which seriously affects the continuity of production.

[0006] 4. In the adhesive layer curing process, traditional processes often use a single hot air drying mode, which results in uneven airflow distribution and difficulty in accurately controlling the curing temperature. This can easily lead to problems such as the surface of the adhesive layer drying and hardening quickly while the inside is not fully cured. At the same time, the air bubbles trapped inside the adhesive layer cannot be expelled in time, which can easily cause quality defects such as delamination and cracking after curing. This results in insufficient adhesion between the adhesive layer and the backing plate, and a low pass rate for finished brake pads.

[0007] 5. In the overall production process, the existing split-type equipment operates independently at each station, requiring manual secondary transfer of workpieces. This results in disjointed process connections and low production efficiency. The open conveyor channels easily attract dust and adhesive mist, corroding conveyor components and shortening equipment lifespan. Furthermore, the unloading process often requires manual supervision, leading to high labor intensity. Additionally, the static electricity generated by friction during workpiece transport easily attracts dust, contaminating incompletely cured adhesive surfaces and affecting finished product quality.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0059] Compared with the prior art, the beneficial effects of the present invention are: I. Batch standardized material feeding and positioning to achieve orderly single-material feeding. The lifting loading plate, paired with symmetrical loading guide chutes, allows for the batch stacking of brake pad backplates. A top-mounted baffle prevents workpieces from slipping off the stack, eliminating the need for manual placement and significantly increasing loading capacity. The synchronized lifting structure of the lifting slide and threaded drive rod stably and precisely raises the top layer of the stacked backplates to the conveyor discharge height, supplying only one workpiece at a time and avoiding jamming and stacking failures caused by simultaneous discharge of multiple backplates. The L-shaped feeding pusher pushes the workpiece laterally, and is equipped with a tapered replaceable alignment guide frame and telescopic baffle column. It can be adapted to back plates of different shapes and sizes. It automatically completes left and right limit alignment during the conveying process. The baffle column extends and retracts in time to realize the orderly release of single workpieces. It solves the problem of back plate conveying offset and misalignment from the source, and provides a regular workpiece posture for subsequent dust removal and glue application processes.

[0060] II. Closed-loop three-dimensional pulse cleaning ensures thorough cleaning and dust removal, preventing secondary pollution. The upper and lower dual-path rotating jet structure forms a three-dimensional dust removal system. The lower rotating jet dust removal seat circumferential jet nozzles flush the dust accumulated on the upper and inner surfaces of the back plate, while the upper pulse side nozzles, which rotate synchronously with the rotating bridge plate, sweep the stubborn oxide debris and metal dust on the upper and outer surfaces of the back plate. The bidirectional airflow impacts the upper and lower airflows, which, compared to single-sided blowing dust removal, completely removes dust and eliminates dust removal dead corners. The pulse side nozzle is equipped with an air intake regulating valve and a diversion pipeline, which can adjust the airflow pressure on both sides according to the degree of dust adhesion on the back plate. For workpieces with severe rust and thick dust, the air pressure is increased, while the air pressure is reduced for thin workpieces, so as to avoid the back plate deformation caused by the impact of high pressure airflow and adapt to the different dust cleaning needs of multiple back plates. The entire dust removal process is completed in a closed dust removal box. Combined with a negative pressure dust collection box and a negative pressure fan, the dust is continuously extracted and stored. The box creates a negative pressure environment, which effectively prevents metal dust from drifting outward. This not only improves dust pollution in the workshop but also prevents floating dust from adhering to the cleaned back plate again, ensuring the cleanliness of the workpiece surface. The upper and lower jetting mechanisms are each equipped with an independent rotating motor and an independent compressed fan. The upper and lower dust removal systems can be started and stopped independently and their power can be adjusted separately. When there is less dust on the workpiece, the upper dust removal mechanism can be turned off to reduce fan energy consumption and reduce equipment no-load losses.

[0061] 3. Servo-guided limit dispensing for precise shape control, effectively preventing glue overflow and leakage. The adjustable glue application limit seat is combined with a detachable glue application masking plate in multiple specifications. Before glue application, the limit seat is pressed down to fit the back plate. The glue application port of the masking plate limits the glue application range, and the remaining area is blocked by the plate. Structurally, this effectively avoids glue overflow and glue spillage from contaminating non-processed areas of the back plate. At the same time, different glue application port masking plates can be quickly replaced. It can adapt to multiple brake pad back plates with different glue application contours without changing the entire set of tooling. Tooling changeover time is short. The multi-axis servo adhesive application robot arm is equipped with a spring-loaded feed tube to continuously deliver adhesive. The robot arm can move along the longitudinal and lateral directions of the workpiece, and the trajectory of the gun is highly controllable. The adhesive layer thickness and coating position accuracy are stable, which solves the problems of adhesive leakage and uneven adhesive layer thickness that exist in manual adhesive application and simple fixed glue gun application. It ensures the consistency of the adhesive application size of the back plate and improves the subsequent bonding strength of the brake pad. The precision glue application box has operation avoidance openings on both sides, and the tooling can be changed without stopping the machine to open the cover. The tooling can be changed during the semi-continuous operation interval of the equipment.

[0062] IV. Air knife drying combined with infrared curing results in uniform curing and excellent adhesion of the adhesive layer. The triangular prism diffuser can disperse the airflow of the drying fan, forming a uniform air knife on both sides. The coated workpiece is first swept by the high-speed air knife to quickly remove the air bubbles trapped inside the adhesive layer, while also removing the solvent on the surface of the adhesive layer, thus achieving preliminary air drying and avoiding defects such as delamination and cracking after the air bubbles inside the adhesive layer have solidified. Multiple sets of equidistant infrared curing lamps at the bottom of the distributor, together with the temperature regulating tubes on both sides, work together to control the temperature. The curing temperature inside the chamber is uniform and stable. Infrared radiation penetrates the adhesive layer and dries it completely. Compared with single hot air drying, the curing speed is faster and the adhesive layer dries inside and out at the same time. There will be no situation where the surface is hard but the inside is not cured, which effectively improves the bonding and adhesion between the adhesive layer and the backing plate.

[0063] 5. Continuous closed conveyor feeding, anti-static to ensure finished product quality. This equipment adopts a fully continuous belt conveyor structure. The conveying height of the feeding, dust removal, gluing, and curing stations is uniform, and the workpieces do not need to be transferred twice. They are continuously conveyed by the feeding conveyor belt, and the various processes are seamlessly connected to achieve uninterrupted continuous processing. The conveyor side plates and enclosed conveyor box seal the conveying channel, reducing the corrosion of the conveying mechanism by dust and glue mist and extending the service life of the belt and rollers. The obliquely set rolling feeder at the end of the conveyor is paired with a grounded C-shaped collection frame. The workpieces slide down obliquely by their own weight and are automatically collected into the receiving plate, eliminating the need for manual intervention at the discharge port. The grounded frame can discharge the static electricity generated by the friction of the back plate conveyor, preventing static electricity from attracting dust and adhering to the freshly cured adhesive surface, thus ensuring the appearance and bonding performance of the finished product. The conveying and unloading are equipped with independent drive motors, and the conveying speed and start / stop timing can be adjusted and controlled separately. This allows for matching the process duration of different workstations such as dust removal, gluing, and curing, making the workpiece processing rhythm flexible and controllable.

[0064] VI. Integrated zoned electrical control design enables unmanned, efficient, and stable production. The main and auxiliary power control cabinets are used for separate management and control. The main power control cabinet coordinates the core processes of material feeding, dust removal, conveying and gluing, while the auxiliary power control cabinet independently manages auxiliary equipment such as curing, unloading and fans. The circuit is laid out in zones, and the auxiliary circuit can be cut off separately when troubleshooting without interrupting the debugging of the core processing station, making the equipment operation and maintenance safer. The fully automated linkage timing control of the entire process eliminates the need for manual intervention, from backplate loading and positioning, sealed dust removal, precise glue application, infrared curing to automatic unloading and collection. This reduces manual loading and unloading, dust cleaning, and manual glue application, lowering the intensity of manual labor. At the same time, it avoids human subjective defects such as workpiece bumps, inadequate cleaning, and glue application size deviation caused by manual operation, greatly improving the consistency of finished product processing. The machine features a fully enclosed box structure for all workstations, with dust and adhesive mist collected and treated in separate areas, preventing dust and volatile adhesive leakage and improving the workshop production environment. Tooling at each workstation can be quickly replaced, and the power of each power mechanism can be independently adjusted. The equipment is compatible with processing multiple models of brake pad backplates, making it a multi-purpose machine that reduces the cost of purchasing multiple dedicated equipment and requires less space in the workshop.

[0118] The main electrical control cabinet 71 is located on one longitudinal side of the enclosed dust removal box 2.

[0119] An auxiliary power control cabinet 72 is provided on one longitudinal side of the power supply box 20.

[0120] When using this invention: First, load and position the brake pads: manually stack the brake pad backplates in the two loading guide chute 6 of the lifting loading plate 5, and the supplementary baffle 7 on the top of the loading positioning box 1 blocks the backplates to prevent them from slipping. After the equipment is started, the internal transmission mechanism of each transmission box 12 synchronously drives the threaded drive rod 11 to rotate, which drives the lifting slide 9 to move vertically down along the lifting limit port 8 to lift the upper material plate 5 and raise the top back plate to the conveying height of the discharge port 14. The L-shaped feeding push plates 13 on both sides of the transverse box wall extend inward simultaneously, pushing the back plate in the feeding guide chute 6 to move towards the discharge port 14.

[0121] Then, the back panel is transferred: the back panel passes through the discharge port 14 and moves to the surface of the two feeding conveyor belts 23. The feeding conveyor motor 22 drives the corresponding conveyor roller 21 to run. The feeding conveyor belt 23 drives the back panel to be transported laterally. It is sent into the closed dust removal box 2 through the conveying connection port 17 between the conveyor side plates 18. During the back panel transport, it passes through the outer tapered alignment guide frame 15 to complete the left and right alignment. The telescopic baffle column 16 inside the alignment guide frame 15 extends to realize the back panel transport alignment. Then, the single back panel is released one by one.

[0122] Then, a closed pulse cleaning process is performed: the lower compressor fan 34 introduces high-pressure airflow into the lower air inlet box 32 through the lower air inlet pipe 35, and the bottom rotating motor 33 drives the jet cleaning seat 37 to rotate continuously. The circumferentially arranged jet nozzles 38 spray high-pressure air onto the upper surface and inner side of the back plate to blow away the metal dust and oxide debris attached to the back plate. The upper compressor fan 42 is started synchronously, and high-pressure gas is sent into the upper air inlet box 40 through the upper air inlet pipe 43. The top rotating motor 41 drives the air inlet distribution box 45 and the rotating bridge plate 47 to rotate as a whole. The airflow is distributed to the pulse side nozzles 49 on both sides through the distribution air inlet pipe 51 and the air inlet regulating valve 50. The arc baffle 48 rotates synchronously with the rotating bridge plate 47. The pulse side nozzles 49 sweep back and forth across the upper surface and outer side of the back plate. The pulse high-pressure airflow peels off the stubborn dust on the upper surface of the back plate. The negative pressure fan 53 continuously draws out the dust-laden air inside the box, and the dust is collected in a centralized manner in the negative pressure dust collection box 52 to prevent the dust from adhering to the back plate again. The entire dust removal process is completely sealed and there is no dust leakage.

[0123] Then, precise glue application is performed: the back plate after dust removal continues to be conveyed forward by the feeding conveyor belt 23, passes through the other side conveyor connection port 17 and enters the closed conveyor box 19, and is conveyed forward to the bottom of the precision glue application box 3. The lifting telescopic cylinder 57 retracts, controls the lifting support seat 56 to move down, drives the glue application limit seat 55 to descend and fit against the back plate surface. The operator can replace the glue application cover plate 59 with different specifications of glue application nozzles as needed through the operation avoidance ports 54 on both sides of the box to adapt to the glue application contour of different models of brake pad back plates. The multi-axis glue-applying robotic arm 62 moves longitudinally and laterally with servo drive. The glue in the feed box 64 is continuously fed to the end glue-applying gun 63 by the spring feed tube 65. The glue-applying gun 63 moves precisely along the glue-applying nozzle reserved on the glue-applying cover plate 59, and only completes the application in the designated area on the back plate. The excess area is blocked by the glue-applying cover plate 59, effectively avoiding glue overflow and leakage.

[0124] Then, after applying the adhesive, the back panel continues to move forward along the closed conveyor box 19 and is sent into the curing box 4 below. Start the drying fan 67 to continuously supply air into the curing chamber 4. The airflow is evenly dispersed by the triangular prism-shaped distribution seat 68 to form two lateral air knife airflows. The adhesive layer is first quickly defoamed and preliminarily dried by the air knife. Multiple sets of infrared curing lamps 70 at the bottom of the distribution seat 68 are turned on simultaneously. Together with the temperature regulating tubes 69 on both sides, the curing temperature in the curing chamber 4 is stabilized. The infrared radiation quickly dries and cures the adhesive layer on the back plate surface, ensuring uniform adhesion of the adhesive layer.

[0125] Finally, the material is collected: the cured back plate is continuously conveyed to the material unloading area at the end of the equipment and falls onto the rolling material unloading belt 26 between the two material unloading conveyor rollers 25. The rolling material unloading belt 26 is driven by the material unloading conveyor motor 29 to roll in a circular motion and convey the back plate downwards at an angle. The workpiece slides down to the receiving plate 28 at the bottom of the grounded C-shaped collection frame plate 27 for unified collection. The collection frame 27 can discharge the static electricity generated during the back panel transfer process, preventing dust from being re-adsorbed on the cured adhesive surface. The complete processing flow of a single back panel is completed, and the equipment cycles through the entire process of feeding, cleaning, applying adhesive, curing, and unloading.

[0126] The main electrical control cabinet 71 coordinates and manages all core unit actions, including feeding, dust removal, conveying, and gluing. The auxiliary electrical control cabinet 72 next to the supporting power supply box 20 separately manages the power supply and start / stop of curing, unloading and conveying, and fan auxiliary equipment. The motors, cylinders, fans, and robotic arms at each workstation are linked in sequence to achieve unmanned continuous automated processing of brake pad backplates.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
