Description

Technical Field

[0001] This utility model relates to the field of micro motor manufacturing technology, and in particular to a conveying device for a micro motor production line. Background Technology

[0002] Micro motors, also known as miniature electric motors, are special-purpose motors with a diameter less than 160mm or a rated power less than 750W. They integrate technologies from multiple disciplines, including motor theory, microelectronics, power electronics, and computer science, and are widely used in control systems or transmission machinery loads to achieve functions such as detection, execution, and conversion of electromechanical signals or energy. During the production and processing of micro motors, components are transported via conveyor systems. However, existing conveyor systems often experience component misalignment during transport, leading to workpiece processing or clamping misalignment.

[0003] Chinese patent CN221342679U discloses a micro-motor processing and conveying device. This device cleans the surface of the conveyor belt with a brush while simultaneously activating a fan. The fan generates suction, drawing dust from the conveyor belt surface into a cylinder through a dust suction hole. The dust is then filtered through a filter screen and transported to a dust collection box through a dust conveying pipe. This process cleans the surface of the conveyor belt, reduces contamination of the micro-motor by impurities, protects the surface of the micro-motor, and improves product quality.

[0004] However, the device still has shortcomings: although the guide structure in the device can adjust the spacing, due to its fixed structure, it cannot actively guide the workpieces of the same model to the center position of the conveyor belt after the spacing is adjusted. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a micro-motor production line conveying device.

[0006] The technical solution of this utility model is as follows: a micro motor production line conveying device, including a frame, a conveyor belt and a drive component A for driving the conveyor belt to run on the frame, a chute on each side of the conveyor belt on the frame, and a discharge hole at the bottom of the frame.

[0007] The slide includes two slides that are slidably disposed in corresponding grooves on the sides. The slide is rotatably connected to the movable frame A. The movable frame A has a number of guide wheels A that are rotatably connected to it along its length. The end of the movable frame A away from the slide is rotatably connected to the movable frame B. The two movable frames B are parallel to each other. The movable frame B has a number of guide wheels B that are rotatably connected to it along its length.

[0008] Drive component B is mounted on the rack and drives the movable frames B on both sides to move closer or further away synchronously.

[0009] The brush roller is rotatably mounted on the inner wall of the feed hole and contacts the bottom surface of the conveyor belt.

[0010] The transmission assembly connects the drive assembly A and the brush roller.

[0011] It also includes a negative pressure dust collection mechanism, which is mounted on the frame and whose input end is connected to the discharge port.

[0012] Preferably, a drive roller and a driven roller are rotatably mounted at both ends of the frame, a conveyor belt drives the drive roller and the driven roller, and the output end of the drive component A is connected to the roller shaft of the drive roller.

[0013] Preferably, the transmission assembly includes pulley A, pulley B and a synchronous belt. Pulley A is coaxially connected to the roller shaft of the drive roller, and pulley B is coaxially connected to the roller shaft of the brush roller. Pulley A and pulley B are connected by a synchronous belt drive, and the outer diameter of pulley A is larger than the outer diameter of pulley B.

[0014] Preferably, the movable frame B and the guide wheel A at the end of the movable frame A away from the slide are coaxially rotatably connected.

[0015] Preferably, the bottom of the frame is provided with an inclined groove that communicates with the discharge hole, the output port of the discharge hole is covered with a receiving hopper, and the output end of the receiving hopper is provided with a guide pipe that communicates with it.

[0016] Preferably, the negative pressure dust collection mechanism includes a water tank and a fan. Both the water tank and the fan are mounted on the frame. The lower end of the feed pipe is inserted into the water tank and located below the liquid surface. The input end of the fan is equipped with an air extraction pipe, and the other end of the air extraction pipe is inserted into the water tank and located above the liquid surface.

[0017] Preferably, a drain pipe is installed at the bottom of the water tank and connected to its interior, a valve for opening and closing the internal channel of the controller is installed on the drain pipe, a feed pipe is installed on the water tank and connected to its interior, and a sealing cap is installed on the feed pipe.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] By setting up a cooperative structure of sliding block, movable frame A and movable frame B, and drive component B, while drive component B drives movable frame B to move closer or further away, movable frame A rotates adaptively, and sliding block slides adaptively. This structure always maintains a wide-mouth guide structure at the feed end of the frame, which facilitates the workpiece to automatically move to the center point of the conveyor belt by following the guide structure. By setting guide wheels A and B, the friction force in the lateral direction of the workpiece during the pushing and guiding process can be reduced, avoiding wear on the workpiece surface. At the same time, this utility model also sets up a brush roller and a negative pressure dust collection mechanism. The brush roller is used to clean the surface of the conveyor belt. The dust and other impurities that fall off enter the water tank under the action of negative pressure suction. The impurities are directly retained in the water, eliminating the need for a filter structure. The structure is simple and easy to clean. Attached Figure Description

The slide block 6 includes two slide blocks 101 that are slidably disposed in corresponding slide blocks 101. The slide block 6 is rotatably connected to the movable frame A7. The movable frame A7 is provided with a number of guide wheels A8 that are rotatably connected to it along its length. The end of the movable frame A7 away from the slide block 6 is rotatably connected to the movable frame B9. The movable frame B9 and the guide wheel A8 at the end of the movable frame A7 away from the slide block 6 are rotatably connected to each other on the same axis. The two movable frames B9 are parallel to each other. The movable frame B9 is provided with a number of guide wheels B10 that are rotatably connected to it along its length. The drive assembly B12 includes, but is not limited to, a bidirectional lead screw 121 and a motor B122. A bracket is mounted on the frame 1, and several guide rods 123 are arranged in parallel on the bracket. A slider 11 is mounted on the movable frame B9, and both sliders 11 are slidably connected to the guide rods 123. The bidirectional lead screw 121 is rotatably mounted on the bracket, and the two sliders 11 are threadedly connected to the corresponding ends of the bidirectional lead screw 121. The motor B122 is mounted on the frame 1, and the output end of the motor B122 is connected to the bidirectional lead screw 123 via a coupling. The brush roller 13 is rotatably mounted on the inner wall of the discharge hole 102 and contacts the bottom surface of the conveyor belt 4. The transmission assembly 14 includes pulley A141, pulley B142, and synchronous belt 143. Pulley A141 is coaxially connected to the roller shaft of the drive roller 2, and pulley B142 is coaxially connected to the roller shaft of the brush roller 13. Pulley A141 and pulley B142 are connected by synchronous belt 143, and the outer diameter of pulley A141 is larger than the outer diameter of pulley B142. The transmission assembly 14 drives the drive assembly A5 and the brush roller 13. The negative pressure dust collection mechanism is mounted on the frame 1.

[0027] In this embodiment, the components of the micro-motor (of the same model) are placed on the upper surface of the conveyor belt 4. Motor B122 is started, driving the bidirectional lead screw 121 to rotate. This causes the two movable frames B9 to move closer together to a distance suitable for the component's size. At this time, the movable frame A7 rotates adaptively and causes the slide block 6 to slide adaptively. Then, motor A is started, driving the conveyor belt 4 to run. Under the guidance of guide wheel A8, the components gradually move towards the center of the conveyor belt 4, and are then laterally limited by guide wheel B. During the operation of the conveyor belt 4, the drive roller 2 drives the brush roller 13 to rotate at high speed. The brush roller 13 brushes the bottom surface of the conveyor belt 4. Simultaneously, the fan 18 is started, drawing air from the water tank 15. This causes dust at the discharge hole 102 and impurities brushed off by the brush roller 13 to enter the water tank 15 along the guide pipe 105 under the action of airflow. The impurities fall into the water, and the air is expelled.
