Description

Technical Field

[0001] The utility model relates to the technical field of keyboard balance bar processing equipment, in particular to a rapid feeding device for a keyboard balance bar. Background Art

[0002] Generally, most of the keys on a keyboard device are keys with square keycaps. A small number of keys, such as the space bar (SPACE), enter key (Enter), caps lock key (Caps Lock), shift key (Shift), etc., have keycaps with a length greater than the width. Such keys are called multiple keys. Because the key surface of the multiple keys is relatively long, when the user presses the keyboard, the finger cannot ensure that it hits the middle position of the keycap every time. If it hits the side, a greater pressure needs to be applied to the keycap to trigger the key effect. Therefore, a balance bar needs to be added to prevent the keycap from tilting up and down due to different force points, so that both ends of the keycap reach a balanced effect, and the user can trigger the key by pressing any position of the keycap.

[0003] However, most of the existing balance bar feeding mechanisms are prone to block the material dropping port during feeding, and after discharging, multiple balance bars of different lengths are stacked together, which is not convenient for the manipulator to grasp, resulting in low feeding efficiency of the keyboard balance bar. Summary of the Utility Model

[0004] In view of this, the utility model provides a rapid feeding device for a keyboard balance bar, which can turn over the balance bars in the storage box, and at the same time, the material dropping cylinder can make a single balance bar fall out, and can separate balance bars of different lengths, improving the feeding efficiency of the keyboard balance bar.

Specific embodiments

[0011] The present utility model will be further described below in conjunction with the attached drawings and embodiments.

[0012] Embodiment 1: A rapid feeding device for a keyboard balance bar, as Figures 1-3As shown in the figure, it includes a chassis, a bottom plate, a bottom block, a retaining frame, an inclined plate, a first blanking chute, a first inclined frame, a first blanking plate frame, a second blanking chute, a second inclined frame, a second blanking plate frame, a third blanking plate frame, a support, a storage box, a rotating shaft, a hexagonal prism, a blanking cylinder, a belt pulley, a belt and a motor. The chassis is in an L-shaped structure. The upper part of the chassis is welded with the bottom plate. The upper part of the chassis is connected with the bottom block by bolts. The bottom block is located below the bottom plate. The upper part of the bottom plate is welded with the retaining frame. The inclined plate is connected to the retaining frame by rivets. The inclined plate is inclined. A first blanking chute is opened on the inclined plate. The upper part of the bottom block is provided with a first inclined frame. The upper part of the first inclined frame is fixedly connected to the bottom plate. The first inclined frame is located directly below the first blanking chute. The upper part of the first inclined frame is welded with the first blanking plate frame. The first blanking plate frame is fixedly connected to the bottom plate. The first blanking plate frame contacts the inclined plate. A number of arc-shaped grooves are opened on the first blanking plate frame. A second blanking chute is opened on the first inclined frame. The length of the second blanking chute is shorter than that of the first blanking chute. The upper part of the chassis is welded with a second inclined frame. The second inclined frame is fixedly connected to the first inclined frame. The second inclined frame is located directly below the second blanking chute. The upper part of the second inclined frame is connected with the second blanking plate frame by bolts. The second blanking plate frame is fixedly connected to the first inclined frame. A number of arc-shaped grooves are opened on the upper part of the second blanking plate frame. The upper part of the chassis is connected with the third blanking plate frame by rivets. The third blanking plate frame is fixedly connected to the second inclined frame. A number of arc-shaped grooves are opened on the third blanking plate frame. The lengths of the arc-shaped groove, the second arc-shaped groove and the third arc-shaped groove decrease in sequence. The upper part of the retaining frame is welded with the support. The upper part of the support is connected with the storage box by bolts. The inside of the storage box is a hollow structure. Through holes are opened on both sides of the storage box. Three rotating shafts are rotatably connected to the lower part of the storage box. A hexagonal prism is connected to the upper two rotating shafts by key. The hexagonal prism passes through the through hole on the storage box. A blanking cylinder is connected to the lower rotating shaft by key. A placement groove is opened on the blanking cylinder. The blanking cylinder is located at the outlet of the storage box. The blanking cylinder contacts the outlet of the storage box. Belt pulleys are connected to the three rotating shafts by key. A belt is wound around the three belt pulleys. A motor is welded to one side of the storage box. The output shaft of the motor is fixedly connected to one of the rotating shafts.

[0013] First, manually pour the keyboard balance rods to be loaded into the storage bin. The blanking cylinder contacts the outlet of the storage bin. The blanking cylinder will block the outlet of the storage bin, and the balance rods will fall onto the placement groove of the blanking cylinder. The placement groove of the blanking cylinder only allows one balance rod to fall in. Then, manually start the motor. The output shaft of the motor drives one of the belt pulleys, one of the rotating shafts, the blanking cylinder and the belt to rotate. The belt drives the other two rotating shafts and two hexagonal prisms to rotate. The two hexagonal prisms will turn the balance rods in the storage bin. The rotation of the blanking cylinder will continuously drive the balance rods falling on the placement groove of the blanking cylinder to rotate. Every time the blanking cylinder rotates one week, one balance rod will fall onto the inclined plate below. When the length of the balance rod is the longest, the balance rod will move downward along the inclined plate and fall into several arc-shaped grooves one of the blanking plate rack one. When the length of the balance rod is shorter, the balance rod will fall into the inclined frame one along the blanking groove one, then move downward along the inclined frame one and fall into several arc-shaped grooves two of the blanking plate rack two. When the length of the balance rod is the shortest, the balance rod will fall into the inclined frame two along the blanking groove two, then move downward along the inclined frame two and fall into several arc-shaped grooves three of the blanking plate rack three. Then, the external manipulator will sequentially pick up and install the balance rods on the blanking plate rack one, the blanking plate rack two and the blanking plate rack three. In this way, it can turn the balance rods in the storage bin, as much as possible to ensure that the balance rods will not block the outlet of the storage bin when falling out. At the same time, the blanking cylinder can make a single balance rod fall out, as much as possible to avoid the balance rods stacking together in the subsequent separation process, and can separate the balance rods of different lengths, which is convenient for the subsequent manipulator to pick up and install, improving the feeding efficiency of the keyboard balance rods.
