Description

Technical Field

[0001] This utility model relates to the field of brake pad transfer technology, specifically to a brake pad transfer mechanism. Background Technology

[0002] Disc brakes, ventilated disc brakes, and friction pad brakes can all be classified as disc brakes. The working principle of disc brakes is similar to that of ordinary bicycle brakes—the brake pads on the caliper and the brake disc connected to the wheel interact with each other during braking until the wheel stops rotating.

[0003] A prior art brake pad hot pressing device, such as the utility model patent document with authorization announcement number "CN220841604U" and patent name "A Multi-layer Rotary Removal Hot Pressing Mold", discloses a brake pad hot pressing device, including a hot pressing box. The top of the hot pressing box has a plurality of hot pressing holes with downward opening. Each hot pressing hole has a plurality of forming blocks arranged vertically. A cavity for product forming is provided between two adjacent forming blocks. A plurality of first heating plates are arranged circumferentially on the side wall of the hot pressing box. A plurality of second heating plates are embedded in the hot pressing box and between the plurality of hot pressing holes. A plurality of removal holes for removing the forming blocks in the hot pressing holes and the formed products are opened on the side wall of the hot pressing box near the bottom.

[0004] According to the aforementioned patent documents, operators need to repeatedly manually remove the brake pads and molds by inserting a removal rod into the hot pressing hole, then separate the parts and reposition the mold. The process is cumbersome, time-consuming, and labor-intensive, making it difficult to adapt to the needs of continuous production. Furthermore, manual handling of the mold in high-temperature environments can easily lead to burns, increasing the risk of workplace injuries. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by proposing a brake pad transfer mechanism. This mechanism solves the technical problems mentioned in the background art, such as the need for operators of the existing brake pad hot pressing device to repeatedly manually remove the brake pads and molds by inserting a removal rod into the hot pressing hole, then separating the parts and repositioning the mold. This process is cumbersome, time-consuming, and labor-intensive, making it difficult to adapt to the needs of continuous production. Furthermore, manual handling of the mold in high-temperature environments can easily lead to burns, increasing the risk of workplace injuries.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A brake pad transfer mechanism includes a conveying frame and a support frame fixed on the conveying frame. The conveying frame contains a conveyor belt, and a first guide rail is fixed on the conveying frame. A movable plate is slidably mounted on the first guide rail. The movable plate has two placement platforms for placing brake pads and molds. The support frame has a first electric push rod for driving the movable plate to move along the conveying direction of the conveyor belt. The support frame has two second electric push rods with their telescopic ends facing the two placement platforms respectively. Each of the telescopic ends of the two second electric push rods has a pushing component for detaching the brake pads from the molds and pushing them onto the conveyor belt. The support frame has two mechanical grippers for transferring the molds in the placement platforms.

[0008] Working principle:

[0009] The first electric push rod drives the moving plate to slide along the first guide rail, moving the two placement platforms to their respective predetermined positions. Once the moving plate reaches its target position, the two second electric push rods move synchronously, driving their telescopic push components to move towards the corresponding placement platform. After contacting the brake pad, the push component sweeps across the upper surface of the brake pad. Then, when the push component is located at the end of the brake pad away from the support frame and abuts against the brake pad, the telescopic ends of the second electric push rods retract, and the push component moves the brake pad from the mold toward the conveyor belt, causing it to detach from the mold. The detached brake pad then falls onto the conveyor belt below. The conveyor belt transports the mold to the next process. After the push assembly completes the demolding, the mechanical grippers on the support frame are activated to grab the empty mold with the brake pads removed. The mechanical grippers fix the mold through a pneumatic or electric clamping mechanism, remove it from the placement table, and transfer it to the designated position to achieve continuous operation. Then, the first electric push rod drives the moving plate back to the initial position, so that the empty placement table is reloaded with new molds and brake pads. Through the reciprocating motion of the electric push rod and the coordinated timing of the mechanical grippers, the fully automated cycle of brake pad demolding, conveying and mold transfer is realized.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, it is equipped with a push assembly. The torsion spring design of the elastic element in the push assembly allows the push block to buffer the push force by rotating when it contacts the mold, and forms a flexible contact surface with the placement groove of the fixed block.

[0012] Second, it is equipped with a first electric push rod, a second electric push rod, and a mechanical gripper. The first electric push rod drives the moving plate to move along the first guide rail to the top pushing position. The second electric push rod, in conjunction with the top pushing assembly, separates the brake pads from the mold. The mechanical gripper, in conjunction with the pneumatic rod, realizes the gripping and transfer of the mold. Attached Figure Description

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] like Figure 1 and Figure 3 As shown, a brake pad transfer mechanism includes a conveying frame 1 and a support frame 2 fixed on the conveying frame 1. The conveying frame 1 is provided with a conveyor belt 3. A first guide rail 4 is fixed on the conveying frame 1. A movable plate 5 is slidably provided on the first guide rail 4. The movable plate 5 is provided with two placement platforms 6 for placing brake pads and molds. The support frame 2 is provided with a first electric push rod 7 for driving the movable plate 5 to move along the conveying direction of the conveyor belt 3. The telescopic end of the first electric push rod 7 is fixed with a mounting block 15. The end of the mounting block 15 away from the first electric push rod 7 is fixedly connected to the movable plate 5. The telescopic end of the first electric push rod 7 pushes the movable plate 5 to slide along the first guide rail 4 through the mounting block 15, so that the placement platform 6 moves to the placement position.

[0020] like Figure 1 and Figure 2As shown, the support frame 2 is provided with two second electric push rods 8, with the telescopic ends of the two second electric push rods 8 facing the two placement platforms 6 respectively. Each of the telescopic ends of the two second electric push rods 8 is provided with a pushing assembly for detaching the brake pads from the mold and pushing them onto the conveyor belt 3. The pushing assembly includes a fixing block 10, a pushing block 11, and an elastic element 12. The fixing block 10 is fixed to the telescopic end of the second electric push rod 8, and a placement groove 13 is formed in the fixing block 10. The pushing block 11 is rotatably disposed in the placement groove 13, and both ends of the pushing block 11 are rotatably connected to the inner walls of both sides of the placement groove 13 respectively. One end of the elastic element 12 is fixed to the placement groove 13, and the other end is connected to the pushing block. 11 is fixed to the end of the second electric push rod 8 away from the position. When the moving plate 5 reaches the placement position, the take-out rod 14 pushes a brake pad and a mold that have been hot-pressed in the hot press box 22 toward the placement table 6. For the specific ejection process, please refer to the utility model patent document with authorization announcement number "CN220841604U" and patent name "A Multi-layer Rotary Take-out Hot Press Mold". It will not be elaborated in detail here. Then, the two second electric push rods 8 extend synchronously, driving the fixed block 10 and the push block 11 to contact the mold. Under the elastic force of the elastic element 12, the push block 11 rotates around the inner wall of the placement groove 13, and uses flexible push force to peel the brake pad off the mold and push it to the conveyor belt 3.

[0021] like Figure 1 and Figure 3 As shown, a guide plate 16 inclined toward the conveyor belt 3 is fixed on the moving plate 5, and the mounting block 15 is located between the guide plate 16 and the moving plate 5. After the push block 11 pushes the brake pad away from the mold, the brake pad slides down the inclined surface of the guide plate 16 onto the conveyor belt 3.

[0022] like Figure 1 and Figure 3As shown, the support frame 2 is equipped with two mechanical grippers 9 for transferring and placing molds inside the placement platform 6. The top of the support frame 2 is equipped with a vertically sliding first sliding plate 17, whose movement direction is perpendicular to the conveying direction of the conveyor belt 3. The first sliding plate 17 is equipped with two moving blocks 18 that move along the conveying direction of the conveyor belt 3. The first sliding plate 17 is also equipped with a second guide rail 30 for the moving blocks 18 to slide. Each of the two moving blocks 18 has a pneumatic rod 19 fixed to its end, with the telescopic ends of the two pneumatic rods 19 facing the placement platform 6. The two mechanical grippers 9 are respectively fixed to the telescopic ends of the two pneumatic rods 19. The mechanical grippers 9 adjust their height by extending and retracting the pneumatic rods 19 to grip the molds on the placement platform 6. The support frame 2 is equipped with a moving frame 20 that moves along the conveying direction of the conveyor belt 3. Two vertical guide rods 21 are fixed to both ends of the moving frame 20. The movable block 18 is slidably mounted on two guide rods 21 at the ends away from the air rod 19. The first sliding plate 17 moves vertically, causing the movable block 18 to slide vertically on the guide rods 21. The movable frame 20 slides laterally, pushing the movable block 18 toward the hot press box 22 and transferring the mold to the designated work station. The support frame 2 is provided with a mounting frame 23, which contains a first screw 24 and a first guide rod 25. One end of the first sliding plate 17 is threadedly connected to the first screw 24, and the other end is slidably connected to the first guide rod 25. The mounting frame 23 is provided with a first motor 26 for driving the first screw 24. The support frame 2 is provided with a second screw 27 and a second guide rod 28. One end of the movable frame 20 is threadedly connected to the second screw 27, and the other end is slidably connected to the second guide rod 28. The support frame 2 is provided with a second motor 29 for driving the second screw 27.

[0023] Working principle:

[0024] The first electric push rod 7 drives the moving plate 5 to slide along the first guide rail 4 via the mounting block 15, moving the two placement platforms 6 to one side of the hot press box 22. The take-out rod 14 pushes out the brake pads and mold inside the hot press box 22 and pushes them onto the placement platform 6. Then, the first electric push rod 7 is activated again to retract, and then the two second electric push rods 8 extend synchronously, driving the fixing block 10 to contact the mold. The pushing block 11 rotates around the inner wall of the placement groove 13 under the elastic force of the elastic element 12, applying a flexible pushing force to the brake pads at an adaptive angle to avoid surface scratches caused by rigid impact. The peeled brake pads slide down the guide plate 16 onto the conveyor belt 3.

[0025] Then, the first motor 26 drives the first screw 24 to rotate, causing the first sliding plate 17 to move in the vertical direction; the second motor 29 drives the second screw 27, causing the moving frame 20 to slide along the conveyor belt 3. The moving block 18 achieves precise lateral positioning through the cooperation of the guide rod 21 and the second guide rail 30. The coordinated movement of the moving frame 20 and the guide rod 21 transfers the mold to the hot press box 22. The guide rod 21 constrains the swaying of the moving block 18 to ensure the stability of the transfer.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
