Description

Technical Field

[0001] This utility model relates to the field of SMD electronic component manufacturing technology, specifically a cleaning device for SMD electronic component manufacturing. Background Technology

[0002] SMD: It is an abbreviation for Surface Mounted Devices, meaning surface mount devices, which are a type of SMT (Surface Mount Technology) component. In the early stages of electronic circuit board production, via assembly was entirely done manually. After the first automated machines were introduced, they could place some simple lead components, but complex components still required manual placement before reflow soldering. Surface mounted components mainly include rectangular chip components, cylindrical chip components, composite chip components, and irregularly shaped chip components. A specific structure is illustrated in a cleaning device for SMD electronic component production proposed in patent publication number CN218532002U, which includes a housing, a cleaning mechanism mounted on the top of the housing, several transmission tubes penetrating the top of the housing connected to the bottom of the cleaning mechanism and along its horizontal direction, a door rotatably connected to one side of the housing, an outer frame located at the center of the bottom of the housing cavity, a motor mounted at the center of the bottom of the housing, and a short rod penetrating the bottom of the housing cavity connected to the top of the motor. The bottom of the outer frame is fixed. A connecting block is connected, the bottom of which is fixedly connected to the top of the short rod. A mounting box is fixedly connected to one side of the outer frame. Both the outer frame and the mounting box have through slots that communicate with each other. A fixing block is slidably connected to the inner cavity of the mounting box. Several connecting blocks that pass through the two through slots are fixedly connected to one side of the fixing block and along its horizontal direction. A movable plate is fixedly connected to the extension end of the connecting block. A fixing plate is provided on one side of the movable plate. The bottom of the fixing plate is fixedly connected to the bottom of the inner cavity of the outer frame. The bottom of the movable plate fits against the bottom of the inner cavity of the outer frame. A base is fixedly connected to each of the four corners of the bottom of the outer shell.

[0003] With the above setup, the existing SMD electronic component production cleaning device moves the corresponding movable plate by connecting the block, adjusts the distance between the movable plate and the adjacent fixed plate, and then the operator places the circuit board between the adjusted movable plate and the fixed plate. The motor drives the short rod to rotate, causing the outer frame to rotate at a uniform speed. The cleaning mechanism, in conjunction with the transmission pipe, washes the circuit board inside the outer frame. This avoids the need for operators to change the clamping module for circuit boards of different thicknesses, and instead adapts to cleaning operations for more circuit boards of different thicknesses and sizes.

[0004] However, existing cleaning devices for SMD electronic component production have the following drawbacks during operation:

[0005] When workers need to clean SMD electronic components of different thicknesses, they need to pull the fixing block and then use the plug to limit the fixing block. However, it is not easy to insert the plug into the socket. Furthermore, using the socket to adjust the distance of the moving plate to clean SMD electronic components of different thicknesses is very limited. At the same time, the SMD electronic components are placed between the moving plate and the fixing plate and only one side has clamping force, which may not be enough. When the motor rotates, it may cause the SMD electronic components to move back and forth, resulting in damage to the SMD electronic components. After cleaning, it is troublesome to disassemble and remove the SMD electronic components, making the operation inconvenient. Utility Model Content

[0006] This utility model aims to provide a cleaning device for SMD electronic component production, mainly to solve the technical problems existing in the prior art where the use of plugs to limit the fixing blocks is not easy to insert into the socket and the clamping force is insufficient.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A cleaning device for SMD electronic component production includes a housing. Bases are fixedly attached to all four sides of the lower end face of the housing. A cleaning mechanism is fixedly attached to the upper end face of the housing. Several transmission pipes are fixedly attached to the bottom of the cleaning mechanism, penetrating the upper end face of the housing and extending into the interior of the housing. A door is rotatably connected to one side of the housing. A motor is fixedly attached to the center of the lower end face of the housing. Brackets are fixedly connected to both sides of the motor, with the end of the bracket furthest from the motor fixedly connected to the lower end face of an outer frame. A short rod penetrating the lower end face of the housing is rotatably connected to the top of the motor. A connecting block is fixedly attached to the upper end face of the short rod, and an outer frame is fixedly attached to the upper end face of the connecting block. Several fixing plates are fixedly attached to the inner wall of the outer frame. A movable plate is provided on one side of each fixing plate. Mounting boxes are fixedly connected to both sides of the outer frame. Through slots are formed on both sides of the outer frame and communicate with the mounting boxes. A rotating assembly for sliding the movable plate is provided inside the mounting box.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When cleaning SMD electronic components, the operator first opens the compartment door. Then, based on the thickness of the SMD electronic component, the distance between the fixed plate and the moving plate inside the outer frame is adjusted. Rotating the rotating assembly moves the corresponding moving plate, adjusting the distance between the moving plate and the adjacent fixed plate. The operator then places the SMD electronic component between the adjusted moving plate and the fixed plate, achieving a clamping and fixing effect. The compartment door is then closed, and the motor is started. The motor drives the short rod to rotate, which in turn drives the connecting block to rotate, causing the outer frame to rotate simultaneously. The cleaning mechanism, in conjunction with the transmission pipe, rinses the SMD electronic components inside the outer frame, cleaning them. Water then flows through the drainage holes at the bottom of the outer frame into the bottom of the inner cavity of the outer shell and is discharged through the outlet pipe. The motor then drives the outer frame to rotate for a short time to achieve a spin-drying effect. Finally, the motor is turned off, and the spun-dry SMD electronic component is removed from the outer frame.

[0011] 2. Beneficial effects:

[0012] Existing technology involves using connecting blocks to move corresponding movable plates, adjusting the distance between the movable plates and adjacent fixed plates, and then placing the circuit board between the adjusted movable and fixed plates for cleaning. However, existing technology uses plugs and sockets to adjust the distance, which is inconvenient to insert and has limited distance control. Furthermore, only one side clamps the circuit board, which may cause it to wobble during rotation, potentially damaging it. This solution installs a rotating component on the outer wall of the frame to adjust the distance between the movable and fixed plates, allowing for simultaneous clamping from both sides with greater clamping force. This solves the problems of inconvenient plug insertion into sockets, limited distance control, and only one side clamping the circuit board.

[0013] Preferably, the rotating assembly includes a threaded rod rotatably connected to the inner walls of two mounting boxes, with one end of the threaded rod penetrating the inner wall of the mounting box and extending outwards. Several threaded blocks are threaded onto the outer wall of the threaded rod, and a connecting block is fixed to one end of each threaded block. One end of the connecting block passes through a slot and is fixed to one end of a movable plate. A pulley is fixed to the end of the threaded rod away from the mounting box, and a belt drives between the two pulleys. Mounting boxes are fixed to both sides of the outer frame, and the mounting boxes communicate with the through slots. By rotating one pulley, the other pulley also rotates due to the belt drive. Since the pulley is fixed to the threaded rod, the rotation of the pulley drives the threaded rod to rotate, the rotation of the threaded rod drives the threaded blocks to slide, and the sliding of the threaded blocks drives the movable plate fixed to them to slide, thereby controlling the distance between the movable plate and the fixed plate to accommodate SMD electronic components of different thicknesses.

[0014] Preferably, a limiting groove is provided at one end of the fixed plate near the moving plate, and an L-shaped plate is slidably connected to one end of the fixed plate, and a limiting block is fixedly connected to one end of the L-shaped plate. The limiting block and the limiting groove are slidably connected. By placing the SMD electronic components on the L-shaped plate and then the moving plate clamps the circuit board, the SMD electronic components can be easily removed by pulling the L-shaped plate after cleaning, making it easier to remove the SMD electronic components.

[0015] Preferably, a circular column is fixed to the outer wall of one of the pulleys, and an anti-slip pad is installed on the outer wall of the circular column. By rotating the circular column, one of the pulleys is driven to rotate, and then the other pulley rotates under the transmission of the belt, making it easier for the operator to adjust the distance between the moving plate and the fixed plate.

[0016] Preferably, the outer walls of the two pulleys are evenly provided with grooves, and the inner wall of the belt is evenly fixed with a number of protrusions, and the protrusions cooperate with the grooves. By fixing a number of protrusions to the inner wall of the belt and opening a number of grooves on the outer wall of the pulley, slippage is prevented when the pulley rotates, which would cause the position of the moving plate to be misaligned.

[0017] Preferably, a handle is fixed to the upper end face of the L-shaped plate to facilitate the removal of the L-shaped plate and the extraction of SMD electronic components.

[0018] Preferably, the threaded rod and the pulley are fixedly connected by bolts so that the belt can be repaired in a timely and better manner if it is damaged.

[0019] Preferably, the movable plate and the L-shaped plate each have placement holes at their opposite ends, and these holes are evenly distributed in an array on the movable plate and the L-shaped plate. Attached Figure Description

Several screw blocks 13 are threaded onto the outer wall of the threaded rod 12, and one end of each screw block 13 is fixedly connected to a connecting block 14. One end of the connecting block 14 passes through a through groove 11 and is fixedly connected to one end of the movable plate 15. A pulley 17 is fixedly connected to the end of the threaded rod 12 away from the mounting box 10, and a belt 18 drives between the two pulleys 17. A circular column 19 is fixedly connected to the outer wall of one of the pulleys 17, and an anti-slip pad is installed on the outer wall of the circular column 19.

Then, the circular cylinder 19 is reversed. The circular cylinder 19 drives the pulley 17, the threaded rod 12, the screw block 13, the connecting block 14, and the movable plate 16. 5. Reverse the rotation so that the placement hole 23 of the moving plate 15 clamps the other end of the SMD electronic component. Then close the door 27 and start the motor 6. The motor 6 drives the short rod 8 to rotate, which in turn drives the connecting block 9 to rotate. The connecting block 9 then drives the outer frame 5 to rotate simultaneously. The cleaning mechanism 3, in conjunction with the transmission pipe 4, washes the SMD electronic components inside the outer frame 5, thus cleaning the SMD electronic components. Then, water flows into the bottom cavity of the outer shell 1 through the drainage hole at the bottom of the outer frame 5 and is discharged through the outlet pipe.
