Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of brake pad production equipment, specifically to a feeding mechanism for a material storage fixture. Background Technology
[0002] Automotive drum brake pads are generally manufactured by pressing powder into shape using molds. In existing processing workshops, we have found that dust is inevitably generated during the production process. This dust mainly comes from the powder conveying and feeding processes. When this dust is not effectively controlled and collected, it will diffuse into the air, forming a dust phenomenon.
[0003] Dust pollution not only affects the production environment of the workshop, but may also have a negative impact on the health of workers. Prolonged exposure to high concentrations of dust may cause workers to inhale large amounts of dust, leading to pulmonary fibrosis and even occupational diseases such as pneumoconiosis. Dust pollution can also cause problems for the normal operation and maintenance of production equipment. Dust adhering to the equipment may lead to decreased equipment performance, increased failure rate, and even shorten the service life of the equipment. At the same time, cleaning dust from the equipment requires additional time and manpower and also results in the waste of raw materials.
[0004] To address the dust problem in the workshop, we designed a dust-free production equipment for brake pads. Brake pad powder is sealed in a plastic film and then placed into a mold. Under high-temperature pressing conditions, the plastic film melts, preventing any impact on the pressing of the brake pads. After the brake pad powder package is loaded into a storage fixture via a filling mechanism, the storage fixture needs to be transferred to a dispensing device. This device then pushes the brake pad powder package from the storage fixture into the production mold. Since the dispensing device is located at a high position, it is impossible to lift the storage fixture from the ground to the dispensing device in one go. Therefore, a feeding mechanism for the storage fixture needs to be designed to solve the aforementioned technical problem. Utility Model Content

[0028] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0029] Please see Figure 1-4 The present invention discloses a feeding mechanism for a storage fixture, comprising a support frame 1, a feeding platform 16, and a fixture gripping mechanism. The feeding platform 16 is located in the middle and near the top of the support frame 1. A feeding mechanism is provided on one side of the support frame 1. A guide rail 5 is fixedly connected to the top of the support frame 1. A driving mechanism is provided on the guide rail 5 to drive the fixture gripping mechanism to move horizontally. A storage fixture positioning mechanism is fixedly connected to the side of the support frame 1 near the feeding mechanism.
[0030] Please see Figure 2 In this embodiment, the feeding mechanism includes a base plate 2, which is fixedly connected to the bottom of one side of the support frame 1. A first cylinder 3 is installed on the top of the base plate 2, and a feeding plate 4 is fixedly connected to the top of the output end of the first cylinder 3. Four anti-detachment rods 401 are fixedly connected to the top edge of the feeding plate 4, and the four anti-detachment rods 401 form a rectangular anti-detachment area.
[0031] With the feeding mechanism in place, when the storage fixture is delivered above the loading plate 4, the operator can accurately place the storage fixture in the center of the loading plate 4 because there are four anti-detachment rods 401 around the loading plate 4. Then the output end of the first cylinder 3 extends, driving the loading plate 4 and the storage fixture to move upward together, raising the storage fixture to the working range of the fixture gripping mechanism.
[0032] It should be noted that, in order to prevent the initial lifting height of the storage fixture from being insufficient or exceeding the set height, a storage fixture positioning mechanism is also provided in this embodiment. Specifically:
[0033] Please see Figure 4 The storage tooling positioning mechanism includes two parallel fixed plates 17. Both fixed plates 17 are fixedly connected to the side of the support frame 1 near the feeding mechanism. A fixed rod 18 is fixedly connected between the two fixed plates 17. A limit structure is slidably connected to the surface of the fixed rod 18.
[0034] The limiting structure includes a movable plate 19, with a limiting plate 21 and a positioning plate 22 fixedly connected to both ends of the movable plate 19, and a movable sleeve 20 fixedly connected to the middle of the movable plate 19. The movable sleeve 20 is slidably connected to the surface of the fixed rod 18. A switch is installed on the lower surface of the limiting plate 21, which is electrically connected to the first cylinder 3. When the upper surface of the storage fixture is in contact with the lower surface of the limiting plate 21, the switch is triggered, causing the first cylinder 3 to stop lifting.
[0035] With the storage fixture positioning mechanism, the operator can slide the limiting plate 21 along the surface of the fixed rod 18 to position the limiting plate 21 at a preset height. Then, by inserting bolts at the four corners of the positioning plate 22, the positioning plate 22 is fixed to the side of the support frame 1, thus fixing the position of the limiting plate 21. When the upper surface of the storage fixture is in contact with the lower surface of the limiting plate 21, the switch is triggered, the first cylinder 3 stops lifting, and the storage fixture reaches the preset position.
[0036] Please see Figure 4 In some other embodiments, the inner wall of the movable sleeve 20 is fixedly connected with an anti-slip ring, the surface of the fixed rod 18 is provided with scale lines, the side section of the limiting plate 21 is an "L" shaped structure, and screw holes are provided at the four corners of the positioning plate 22. The positioning plate 22 is fixedly connected to the side wall of the support frame 1 by bolts.
[0037] The set scale lines make it easy for staff to confirm the position of the limit plate 21 when adjusting its height. The anti-slip ring increases friction and prevents the height of the limit plate 21 from dropping when tightening bolts, thus facilitating the tightening of bolts.
[0038] Please see Figure 3In this embodiment, the driving mechanism includes a stepper motor 6, a ball screw 7, and a screw nut. The stepper motor 6 is installed on one side of the guide rail 5. The ball screw 7 is rotatably connected between the two ends of the inner wall of the guide rail 5. The screw nut is installed on the surface of the ball screw 7. The tooling gripping mechanism includes a first connecting plate 9. A slider 8 is fixedly connected to one end of the lower surface of the first connecting plate 9. The slider 8 is fixedly connected to the screw nut.
[0039] A second cylinder 10 is fixedly connected to the upper surface of the first connecting plate 9 and the end away from the slider 8. The bottom of the output end of the second cylinder 10 passes through the bottom of the first connecting plate 9 and is fixedly connected to the second connecting plate 13. Both ends of the second connecting plate 13 are fixedly connected to the third cylinder 14. A gripper 15 is fixedly connected to the output end of the third cylinder 14.
[0040] With the above technical solution, when the storage fixture rises to the preset position, the stepper motor 6 starts to rotate forward, driving the fixture clamping mechanism to reach directly above the storage fixture and then stopping. Then, the output end of the second cylinder 10 extends downward, so that the gripper 15 aligns with both sides of the storage fixture. After that, the third cylinder 14 retracts, so that the gripper 15 inserts into both sides of the storage fixture. At this time, the gripper 15 clamps the storage fixture. Then, the stepper motor 6 starts to rotate forward again, driving the storage fixture to move horizontally a certain distance and then stopping. At this time, the upper surface of the storage fixture separates from the limit plate 21. Then, the output end of the second cylinder 10 retracts, lifting the storage fixture. When the storage fixture rises to a certain height, the stepper motor 6 starts to rotate in reverse, moving the storage fixture above the feeding platform 16 and placing the storage fixture on the feeding platform 16, thus completing one feeding operation.
[0041] In some other embodiments, guide sleeves 11 are fixedly connected to the upper surface of the first connecting plate 9 and to both sides of the second cylinder 10. A guide rod 12 is slidably connected inside the guide sleeve 11. The bottom of the guide rod 12 passes through the bottom of the first connecting plate 9 and is fixedly connected to the top of the second connecting plate 13. By using the guide sleeve 11 and the guide rod 12, the stability of the second connecting plate 13 during the rising and falling process can be improved.
[0042] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
