Description

Technical Field

[0001] The utility model relates to the technical field of brake pad production equipment, in particular to a powder filling mechanism for automobile brake pads. Background Art

[0002] Automobile drum brake pads are generally manufactured by pressing powder into shape through a mold. In the processing workshop of the prior art, we found that powder will inevitably generate dust during the production process. The dust mainly comes from the transportation and feeding of the powder. When the dust is not effectively controlled and collected, it will diffuse in the air and form dust.

[0003] The dust problem not only affects the production environment of the workshop, but may also have a negative impact on the health of workers. If workers are exposed to a high concentration of dust for a long time, they may inhale a large amount of dust, leading to fibrosis of lung tissue and even occupational diseases such as pneumoconiosis. Powder dust will also cause troubles for the normal operation and maintenance of production equipment. Dust attached to the equipment may cause equipment performance to decline, failure rate to increase, and even shorten the service life of the equipment. At the same time, cleaning the dust on the equipment also requires extra time and manpower, and will also cause waste of raw materials.

[0004] In order to solve the dust problem in the workshop, we designed a dust-free equipment for producing brake pads. The brake pad powder is packed in a plastic film and then the sealed powder bag is put into the mold. Under the high-temperature pressing environment, the plastic film will melt and will not affect the pressing of the brake pad. If the powder package is filled into the storage tooling manually, it will not only be inefficient but also easily cause damage to the powder package. Therefore, we need to design a powder filling mechanism according to the characteristics of the powder package, so as to efficiently and orderly fill the brake pad powder package into the powder storage tooling.

For ordinary technicians in this field, the specific meanings of the above terms in this technology can be understood according to specific circumstances.

[0025] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it.

[0026] See also Figure 1-4 The utility model discloses a vehicle brake pad powder filling mechanism, comprising a belt conveyor 1, a feeding platform 10 and a stacking structure, wherein the feeding platform 10 is located behind the tail of the belt conveyor 1, and the stacking structure is located on the left side of the feeding platform 10. The belt conveyor 1 comprises a frame and a conveying mechanism, wherein the conveying mechanism comprises a belt and a reduction motor, wherein the reduction motor drives the belt to rotate on the frame, a baffle structure is fixedly connected to the top of the frame, a first pushing mechanism is fixedly connected to the tail of the frame, and a second pushing mechanism is fixedly connected to the right side of the feeding platform 10, so the stacking structure comprises a support frame 13, a guide rail 14 is fixedly connected to the top of the support frame 13, a reciprocating motion mechanism and a clamping mechanism are installed on the guide rail 14, and the reciprocating motion mechanism drives the clamping mechanism to move in the horizontal direction.

[0027] Considering that when the powder bag enters the belt conveyor 1, the material inside the powder bag will be uneven and irregular in shape, which is easy to get stuck in the subsequent pushing and filling process, a baffle structure is provided to level the powder bag. Specifically:

[0028] like Figure 2 As shown, the baffle structure includes a first baffle 2, a second baffle 3, a third baffle 5 and a fourth baffle 9. The first baffle 2 and the second baffle 3 are fixedly connected to both sides of the upper surface of the frame near the center, and the first baffle 2 and the second baffle 3 are symmetrically arranged. The second baffle 3 is fixedly connected to a limited height baffle 4 at positions near both sides, the third baffle 5 is fixedly connected to the upper surface of the frame and near the left side of the second baffle 3, and the fourth baffle 9 is fixedly connected to the upper surface of the frame and near the tail. Both sides of the first baffle 2, the second baffle 3 and the third baffle 5 are integrally formed with a bending portion.

[0029] Through the above technical solution design, the first baffle 2 and the second baffle 3 are symmetrically arranged with a channel in the middle. When the powder bag passes through the channel via the belt conveyor 1, its two sides will be flattened under the action of the bending part, and the height limiting baffle 4 can flatten the top of the powder bag. The setting of the third baffle 5 can prevent the powder bag from falling from the side of the belt conveyor 1. The setting of the fourth baffle 9 can prevent the powder bag from falling from the tail of the belt conveyor 1, and at the same time limit the position of the powder bag. When the powder bag touches the fourth baffle 9, its side will also become flat, which is conducive to the subsequent pushing work.

[0030] In this embodiment, in order to push the powder bag transported to the tail into the storage tooling, the first pushing mechanism includes a first support plate 6, the first support plate 6 is fixedly connected to the tail of the frame and close to the right side of the fourth baffle 9, a first cylinder 7 is installed on the top of the first support plate 6, and a first push block 8 is fixedly connected to the output end of the first cylinder 7.

[0031] When the powder bag is transported to the tail of the belt conveyor 1 and fits with the fourth baffle 9, the output end of the first cylinder 7 extends, and the first push block 8 pushes the powder bag into the storage tooling placed in advance on the loading platform 10, completing a loading.

[0032] See also Figure 1 In this embodiment, the second pushing mechanism includes a second support plate 11, which is fixedly connected to the center of the right side of the loading platform 10. A second cylinder 12 is installed on the top of the second support plate 11, and a second push block is fixedly connected to the output end of the second cylinder 12.

[0033] See also Figure 1In order to carry out the loading work continuously, at least two storage tools are placed on the loading platform 10. The two storage tools are arranged side by side, and one of the storage tools corresponds to the position of the first cylinder 7. When the storage tool is filled, it is taken away by the stacking structure for stacking. Then the output end of the second cylinder 12 extends to push the other storage tool to the loading position. When the stacking structure completes a stacking, it will add the empty storage tool to the loading platform 10, so as to realize continuous loading and greatly improve work efficiency.

[0034] See also Figure 3 and Figure 4 In this embodiment, the reciprocating motion mechanism includes a stepper motor 15, a ball screw 16 and a screw nut 17. The ball screw 16 is rotatably connected to the two ends of the inner side of the guide rail 14. The output end of the stepper motor 15 is fixedly connected to one end of the ball screw 16. The screw nut 17 is installed on the surface of the ball screw 16. A connecting plate 18 is fixedly connected to the screw nut 17. The clamping mechanism is fixedly connected to the connecting plate 18. The clamping mechanism includes a third cylinder 19. A fixed plate 20 is fixedly connected to the bottom of the output end of the third cylinder 19. Both ends of the upper surface of the fixed plate 20 are fixedly connected to a fourth cylinder 21. A clamping claw 22 is fixedly connected to the output end of the fourth cylinder 21.

[0035] Through the above technical solution, the staff can control the horizontal movement direction of the second cylinder 12 through the stepper motor 15, so that the second cylinder 12 can be aligned with the empty storage tools on the cargo rack and the full storage tools on the loading platform 10. Through the connecting plate 18, the third cylinder 19 and the clamping claw 22 set on the output end of the second cylinder 12, the device can clamp the storage tools and move them, which is convenient for stacking and loading.

[0036] In summary, the loading process of the device is as follows: first, the powder bags are placed one by one at the head of the belt conveyor 1, and the belt conveyor 1 drives the powder bags to move toward the tail thereof at a constant speed. During the movement, the powder bags pass between the first baffle 2 and the second baffle 3, and the height-limiting baffle 4 is set to level the powder bags. After the powder bags contact the fourth baffle 9, the first cylinder 7 is actuated to push the powder bags into the storage tooling on the loading platform 10;

[0037] When the storage tool is filled with powder bags, the output end of the second cylinder 12 descends, so that the clamping claws 22 are aligned with both sides of the filled storage tool, and then the third cylinder 19 retracts to clamp the filled storage tool, and then the output end of the second cylinder 12 retracts, and the stepper motor 15 is started to drive it to move to the shelf to stack the filled storage tool;

[0038] It should be noted that if Figure 1As shown, the shelf is arranged below the support frame 13 and to the side of the loading platform 10, and a part of the shelf is placed with empty storage tools for replenishment, and the other part is used for stacking filled storage tools;

[0039] During the palletizing process, the second cylinder 12 is activated to push the storage tooling above the loading platform 10 to the position corresponding to the first cylinder 7, waiting for the next loading work to be carried out;

[0040] After a stacking operation is completed, the grabbing mechanism picks up the empty storage tooling on the shelf, and then transports it to an empty space on the loading platform 10 and puts it down, thus completing a cycle.

[0041] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
