Description

Technical Field

[0001] The present invention relates to the technical field of brake pad processing and conveying, and more specifically, to a high-efficiency automatic conveying mechanism for brake pad spraying processing. Background Art

[0002] Brake pads are also called brake pads. In the braking system of a car, brake pads are the most critical safety parts, so the quality of braking effect is determined by brake pads. In the production of brake pads, it is usually necessary to spray wear-resistant materials on the brake pads to improve the wear resistance of the brake pads.

[0003] After searching, the patent number CN110802462B discloses "A device for surface treatment of friction materials for brake pad production and processing", which puts the stacked brake pads into an anti-reverse limit discharge bin, and realizes intermittent delivery of the brake pads through a conveying mechanism. The push block on the conveyor belt will push the brake pad at the bottom forward and deliver it during the forward movement through the anti-reverse limit discharge bin; However, in the actual conveying process, due to the stacking arrangement of the brake pads, the brake pad at the bottom will be pressed by all the brake pads above. There is a certain resistance when the push block is used to push the brake pad at the bottom out of the discharge bin during the conveying process. It is necessary to give the conveyor belt a greater power to enable the push block to push the brake pad at the bottom out of the discharge bin. The conveying process is not convenient, and the conveyor belt is easily worn during the long-term conveying and pushing process. In addition, after the brake pad is pushed to the bottom of the grinding device, it can only be processed on one side. Patent No. CN116510933A discloses "A fully automatic spraying device for brake pads". Through the setting of an automatic flipping mechanism, the intermittent turntable is driven to rotate by the connecting column to realize automatic flipping of the brake pad during the spraying process; however, after the first side of the brake pad is sprayed, it is immediately transferred to the intermittent turntable without performing a curing operation. After the intermittent turntable rotates to the other side, during this process, one side of the brake pad sprayed with powder coating contacts the intermittent turntable and is then transferred to another conveyor belt. The coating is very fragile and can be easily damaged by external forces, resulting in scratches or peeling on the coating surface, and there are certain processing disadvantages.

[0004] To this end, we proposed a high-efficiency automated conveying mechanism for brake pad spraying processing to address the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that it is inconvenient to efficiently transport stacked brake pads to the processing station and the brake pads are prone to coating friction during the processing. Compared with the existing technology, an efficient automatic conveying mechanism for brake pad spraying processing is provided.

[0006] The purpose of the present invention can be achieved through the following technical solutions: a high-efficiency automatic conveying mechanism for brake pad spraying processing, comprising a traction rail suspended and installed above an operating table and in an annular closed structure, a plurality of connecting frames based on the annular structure for conveying are evenly distributed on the traction rail, a clamping mechanism for clamping the brake pad is installed at the lower end of the connecting frame, and the clamping mechanism includes a driving seat fixedly installed at the bottom end of the connecting frame, a rotating column is installed inside the driving seat through a driving motor, and one end of the rotating column is externally connected to a clamp for clamping the side end face of the brake pad and can be turned up and down; A discharge bin located below the edge of the traction rail and used for pre-loading brake pads is embedded on one side of the upper end of the operating table; an electric push cylinder is fixedly installed at the bottom of the discharge bin and supports and transports the bottommost brake pad upward; a spray box is installed on the upper end of the operating table, which is arranged adjacent to the discharge bin and has a turning space reserved; spray structures for spraying double-sided brake pads are embedded on the front and rear sides of the spray box; the other end of the spray box is connected to a drying box with a U-shaped structure and the other end extends in the opposite direction to the rear side of the spray box.

[0007] Furthermore, the clamp includes an inner clamp fixedly mounted on the rotating column and an outer clamp docked at the outer end of the inner clamp, and a clamping groove adapted to the brake pad structure is formed between the inner clamp and the outer clamp.

[0008] Furthermore, a plurality of adsorption holes penetrating inside and outside are provided on the inner end wall of the inner clamp, a ventilation hole connected to the plurality of adsorption holes is provided inside the rotating column, and an end of the rotating column away from the driving motor is externally connected to an air pump fixed on a connecting frame through an air pipe. When the connecting frame drives the clamping mechanism to transport it to the top of the discharge bin, the brake pad is pushed upward by an electric push cylinder, and the top brake pad is pushed into the clamping groove. At this time, the air pump is started, and the end wall on one side of the brake pad is negatively pressure adsorbed and positioned by using the plurality of adsorption holes.

[0009] Furthermore, the outer clamp and the inner clamp are movably connected to each other, and the inner walls on the left and right sides of the inner clamp are also provided with negative pressure holes connected to the adsorption holes. A pair of negative pressure holes are movably connected inside with a piston rod extending to the outside and fixedly connected to the inner end wall of the outer clamp, and the inner end wall of the negative pressure hole close to the outside is fixedly connected with a tension spring that is sleeved on the piston rod and fixedly connected to the inner end of the piston rod.

[0010] Furthermore, the negative pressure hole is in an L-shaped structure, and the piston rod is installed at the outer end of the straight section of the negative pressure hole, and a movable docking is arranged between the outer clamp and the inner clamp. When the air pump is closed, the outer clamp is separated from the inner clamp under the action of the tension spring, which appropriately increases the clamping space of the clamping groove. When the clamp is transported to the upper end surface of the brake pad, it pushes the brake pad upward until the top brake pad moves into the clamping groove and fits with the inner end wall of the clamping groove. At this time, the air pump is started, and the end wall of one side of the brake pad is negatively adsorbed and positioned by using multiple adsorption holes. At the same time, negative pressure is also generated inside the negative pressure hole, driving a pair of piston rods to move toward the inside of the negative pressure hole, so that the outer clamp moves toward one side of the inner clamp to clamp the other end surface of the brake pad, thereby improving the stability of the brake pad in the clamping groove.

[0011] Furthermore, a loading trough for embedding and installing a material bin is provided on the upper end wall of the operating table, and a driving box for installing an electric push cylinder is fixed on the lower end wall of the operating table.

[0012] Furthermore, the discharge bin includes a bin body, a bin plate is butt-jointedly installed on the outside of the bin body, a discharge cavity for stacking brake pads and adapted to its structure is formed between the bin body and the bin plate, a through opening is provided at the bottom of the discharge cavity for the telescopic end of the electric push cylinder to extend through, multiple brake pads are stacked from bottom to top in the discharge cavity of the bin body in advance, and then the bin plate is butt-jointedly installed from the edge of the bin body to complete the rapid loading of the brake pads.

[0013] Furthermore, the spraying structure includes a plurality of powder boxes installed on the front and rear sides of the spray box, each powder box is connected to a spray gun that penetrates into the interior of the spray box, the powder box is loaded with electrostatic powder coating, the spray gun and the powder box are prior art, the spray gun is controlled by an external switch and is electrically connected to an external power supply, when the spray gun is started, the electrostatic powder coating inside the powder box can be sprayed out, and the front and rear end surfaces of the brake pad can be sprayed synchronously.

[0014] Compared with the prior art, the advantages of the present invention are: (1) This scheme is to set up multiple groups of clamping mechanisms based on the circular direction of the traction rail for rotating transportation, and set up a discharge bin, a spray box and a drying box arranged in a U shape on the operating table. When spraying, after the clamping mechanism is transported to the top of the discharge bin, the stacked brake pads are pushed upward by an electric push cylinder until the top brake pad is pushed into the clamp to complete the adsorption clamping. In the process of conveying the brake pads to the spray box, the clamp is flipped downward to facilitate the conveying of the hanging brake pads to the spray box and the drying box in turn, complete the double-sided simultaneous spraying and subsequent curing treatment. The whole conveying process is efficient and coherent. Compared with using the conveying mechanism to push the bottom brake pad of the stacked setting, the clamping mechanism is used to clamp the top brake pad and then convey it vertically in a suspended manner. It is not only convenient for clamping, positioning and conveying, but also protects the conveying mechanism and will not cause friction to the coating during the conveying process.

[0015] (2) This scheme also optimizes and improves the structure of the clamp, and adopts a movable docking installation method between the outer clamp and the inner clamp. When the air pump is turned off, the outer clamp is separated from the inner clamp under the action of the tension spring, which appropriately increases the clamping space of the clamping groove. When the clamp is transported to the upper end surface of the brake pad, it pushes the brake pad upward until the uppermost brake pad moves into the clamping groove and fits with the inner end wall of the clamping groove. At this time, the air pump is started, and the end wall of one side of the brake pad is negatively adsorbed and positioned using multiple adsorption holes. At the same time, negative pressure is also generated inside the negative pressure hole, driving a pair of piston rods to move toward the inside of the negative pressure hole, so that the outer clamp moves toward one side of the inner clamp to clamp the other side of the brake pad, thereby improving the stability of the brake pad in the clamping groove.

[0020] A discharge bin 11 located below the edge of the traction rail 2 and used for pre-loading the brake pad 8 is embedded and installed on one side of the upper end of the operating table 1. An electric push cylinder 12 is fixedly installed at the bottom of the operating table 1, which penetrates the bottom of the discharge bin 11 and supports and transports the bottommost brake pad 8 upward. A loading trough for embedding and installing the discharge bin 11 is opened on the upper end wall of the operating table 1. A drive box 10 for installing the electric push cylinder 12 is fixed on the lower end wall of the operating table 1. See also Figure 2 , Figure 3 The discharge bin 11 includes a bin body 111, and a bin plate 112 is installed on the outside of the bin body 111. A discharge cavity for stacking brake pads 8 and adapted to its structure is formed between the bin body 111 and the bin plate 112. A through hole for the telescopic end of the electric push cylinder 12 to extend through is opened at the bottom of the discharge cavity. Multiple brake pads 8 are stacked from bottom to top in the discharge cavity of the bin body 111 in advance, and then the bin plate 112 is installed from the edge of the bin body 111 to complete the rapid loading of the brake pads 8; Then place the discharge bin 11 in the loading trough of the operating table 1, start the electric push cylinder 12, use the electric push cylinder 12 to push the brake pad 8 upward, and then use the clamp 7 that is continuously transported to the top of the discharge bin 11 to clamp the top brake pad 8. When the clamp 7 is transported to the turning space between the discharge bin 11 and the spray box 13, flip the clamp 7 downward to facilitate the vertically suspended brake pad 8 to be transported to the spray box 13 for spraying. After spraying, the drying box 16 performs long-path drying treatment.

[0021] See also Figure 1 and Figure 7 A spray box 13 is installed on the upper end of the operating table 1, which is arranged adjacent to the discharge bin 11 and has a turning space reserved. A spray structure for spraying the brake pad 8 on both sides is embedded on the front and rear sides of the spray box 13. The spray structure includes a plurality of powder boxes 14 installed on the front and rear sides of the spray box 13. Each powder box 14 is connected to a spray gun 15 that penetrates into the spray box 13. The powder box 14 is loaded with electrostatic powder coating. The spray gun 15 and the powder box 14 are prior arts. The spray gun 15 is controlled by an external switch and is electrically connected to an external power supply. When the spray gun 15 is started, the electrostatic powder coating in the powder box 14 can be sprayed out, and the front and rear end surfaces of the brake pad 8 can be sprayed synchronously.

[0022] See also Figure 1 and Figure 8 The other end of the spray box 13 is connected to a drying box 16 which is arranged in a U-shaped structure and the other end of which extends in the opposite direction to the rear side of the spray box 13. The drying box 16 is connected to the inside of the spray box 13. After the brake pad 8 is sprayed, it is directly transported to the drying box 16 for drying and curing. After being dried along the U-shaped conveying path of the drying box 16, it is transported out from the outlet of the drying box 16; A material unloading platform is added at the exit of the drying box 16, and a turning space is also reserved between the material unloading platform and the exit of the drying box 16. After the clamp 7 drives the vertically suspended brake pad 8 to be transported to the outside of the drying box 16, the driving motor 6 is used to flip the clamp 7 upward until it is parallel to the upper end surface of the material unloading platform. When the clamp 7 is transported to the material unloading platform, the negative pressure adsorption of the clamp 7 on the brake pad 8 is released, so that the brake pad 8 is transported out of the material unloading platform, completing one round of brake pad processing.

[0023] Embodiment 2: Based on Embodiment 1, this embodiment improves and optimizes the structure of the clamp 7 to improve the clamping and conveying efficiency, specifically: See also Figure 1 , Figure 2 as well as Figure 4 , Figure 5The clamp 7 includes an inner clamp 71 fixedly mounted on the rotating column 5 and an outer clamp 72 docked at the outer end of the inner clamp 71, a clamping groove 73 adapted to the structure of the brake pad 8 is formed between the inner clamp 71 and the outer clamp 72, a plurality of adsorption holes 711 penetrating inside and outside are provided on the inner end wall of the inner clamp 71, a vent hole 501 connected to the plurality of adsorption holes 711 is provided inside the rotating column 5, an end of the rotating column 5 away from the driving motor 6 is externally connected to an air pump 9 fixed on the connecting frame 3 through an air pipe, when the connecting frame 3 drives the clamping mechanism to be transported to the top of the discharge bin 11, the brake pad 8 is supported upward by the electric push cylinder 12, and the uppermost brake pad 8 is supported into the clamping groove 73, at this time, the air pump 9 is started, and the end wall of one side of the brake pad 8 is negatively adsorbed and positioned by using the plurality of adsorption holes 711; The outer clamping piece 72 is movably connected to the inner clamping piece 71, and the inner walls on the left and right sides of the inner clamping piece 71 are also provided with negative pressure holes 712 connected to the adsorption holes 711. A pair of negative pressure holes 712 are movably connected inside with piston rods 74 extending to the outside and fixedly connected to the inner end wall of the outer clamping piece 72. The inner end wall of the negative pressure hole 712 close to the outside is fixedly connected with a tension spring 75 sleeved on the piston rod 74 and fixedly connected to the inner end of the piston rod 74. The negative pressure hole 712 is an L-shaped structure, and the piston rod 74 is installed at the outer end of the straight section of the negative pressure hole 712; An active docking is set between the outer clamping piece 72 and the inner clamping piece 71. When the air pump 9 is closed, the outer clamping piece 72 is separated from the inner clamping piece 71 under the action of the tension spring 75, and the clamping space of the clamping groove 73 is appropriately increased. When the clamp 7 is transported to the upper end surface of the brake pad 8 in a horizontal state, the transportation of the traction rail 2 is stopped, and the clamp 7 is stably located at the upper end surface of the brake pad 8. The clamping groove 73 corresponds to the discharge cavity position of the discharge bin 11, and the brake pad 8 is supported upward until the uppermost brake pad 8 is transported to the clamping groove 73 and fits with the inner end wall of the clamping groove 73; At this time, the air pump 9 is started, and the end wall of one side of the brake pad 8 is negatively adsorbed and positioned by using the multiple adsorption holes 711. At the same time, negative pressure is also generated inside the negative pressure hole 712, driving the pair of piston rods 74 to move toward the inside of the negative pressure hole 712, so that the outer clamping piece 72 moves toward the side of the inner clamping piece 71 to clamp the other side end surface of the brake pad 8, thereby improving the stability of the brake pad 8 in the clamping groove 73; See also Figure 6 , Figure 7After the brake pad 8 is clamped, the fixture 7 is continuously conveyed to the spray box 13. When the fixture 7 is located in the turning space between the discharge bin 11 and the spray box 13, the driving motor 6 is used to turn the fixture 7 downward until the brake pad 8 is in a vertical hanging state, and then the brake pad 8 is conveyed to the spray box 13. The fixture 7 and the brake pad 8 are located in the spray box 13, and a conveying cavity for the horizontal conveying of the driving seat 4 based on the traction rail 2 is provided at the top of the spray box 13 and the drying box 16. The driving seat 4 and the driving motor 6 and other structures are located outside the conveying cavity, and the front and rear surfaces of the brake pad 8 to be sprayed are sprayed by using two groups of spray guns 15 arranged at the front and rear; After spraying, it is directly transported to the drying box 16 for long-path drying and curing. Figure 8 When the brake pad 8 is transported to the outside of the drying box 16, the air pump 9 is disconnected to release the negative pressure environment in the inner clamp 71, and the outer clamp 72 is appropriately separated from the inner clamp 71 to increase the clamping space of the clamping groove 73, so that the brake pad 8 is downwardly separated from the clamp 7, which is convenient for transporting the brake pad 8 outward.

[0024] In summary: multiple groups of clamping mechanisms are arranged under the traction rail 2 based on the circular direction of the rotational conveyance, and a discharge bin 11, a spray box 13 and a drying box 16 arranged end to end in a U shape are arranged on the operating table 1. When the spraying work is performed, after the clamping mechanism is transported to the top of the discharge bin 11, the stacked brake pads 8 are supported upward by the electric push cylinder 12 until the top brake pad 8 is pushed into the clamping groove 73 of the clamp 7 for adsorption and clamping, thereby completing the preliminary positioning of the brake pad 8 in a horizontal state; In the process of conveying the brake pad 8 to the spray box 13, the clamp 7 is turned down in the turning space to facilitate conveying the vertically suspended brake pad 8 to the spray box 13, and the front and rear end surfaces of the brake pad 8 are synchronously sprayed through the spray structures on the front and rear sides of the spray box 13. After the spraying is completed, it is dried in a long path through the drying box 16 under continuous conveying. Compared with using the conveying mechanism to push the bottom brake pad in the stacking arrangement, the clamping mechanism is used to clamp the top brake pad, which is not only convenient for clamping, positioning and conveying, but also protects the conveying mechanism. In addition, the downward turning action is used to facilitate the vertically suspended conveying of the brake pads 8 one by one into the spray box 13 for double-sided synchronous spraying, which will not cause friction damage to the coating; After the drying and curing work is completed, the brake pad 8 is transported to the outside of the drying box 16, and the driving motor 6 is used to flip the clamp 7 upward until it is parallel to the upper end surface of the unloading table. When the clamp 7 is transported to the unloading table, the air pump 9 is disconnected to release the negative pressure environment in the inner clamp 71, and the outer clamp 72 is moderately separated from the inner clamp 71 to increase the clamping space of the clamping groove 73, so that the brake pad 8 is separated from the clamp 7 downward, which is convenient for conveying the brake pad 8 outward, and the entire conveying process is efficient and coherent.

[0025] The above is only a preferred specific implementation manner of the present invention; but the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered by the protection scope of the present invention.
