Description

Technical Field

[0001] This utility model belongs to the technical field of PCBA loading frame, specifically a sliding rail type PCBA loading frame that is easy to move. Background Technology

[0002] PCBA loading frames are multifunctional material handling and turnover devices specifically designed for printed circuit board assemblies (PCBAs). They are typically made of anti-static materials (such as conductive plastics or carbon fiber composites) and feature a structure incorporating layered partitions, slot positioning, or sliding rail designs. This allows for the secure fixing of PCBAs of different sizes, preventing component detachment or circuit damage during transportation or storage due to collisions or static electricity. Their applications cover the entire electronics manufacturing process: in SMT assembly and wave soldering production lines, they are used for batch transfer of PCBAs to the next process; in aging testing and functional testing stages, they serve as standardized carriers for simultaneous multi-board testing; and in warehousing and logistics, they work with intelligent warehousing systems to achieve material traceability via barcodes / RFID tags. By improving turnover efficiency and reducing loss rates, this device has become a key auxiliary device for ensuring the quality of electronic products and production continuity.

[0003] The existing PCBA loading frame cannot adjust the placement width, resulting in poor adaptability and incompatibility with different sized boards, causing wasted space or loose boards; the frame needs to be frequently replaced during production to match the products, increasing labor and time costs.

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a sliding rail type PCBA loading frame that is easy to move. It effectively solves the problem that the existing PCBA loading frames cannot adjust the placement width, resulting in poor adaptability and incompatibility with different sized boards. The frame needs to be frequently replaced to match the products during production, which increases manpower and time costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a movable sliding rail type PCBA loading frame, including a base plate, support rods fixedly installed at the four corners of the top of the base plate, a top plate fixedly installed between the tops of the four support rods, a fixed frame fixedly installed on one side between the top plate and the base plate, a movable frame provided in the middle between the top plate and the base plate, several placement slots opened on the side of the fixed frame and the movable frame that are close to each other, four limiting blocks provided on the other side of the movable frame, anti-slip pads fixedly installed on the inner walls of the limiting blocks, a handle provided in the middle of the other side of the movable frame, a transmission component provided at one end of the handle, a protective plate covering the transmission component fixedly installed on the side of the movable frame away from the fixed frame, two slide rails fixedly installed on the side of the top plate and the base plate that are close to each other, two sliders opened on the top and bottom of the movable frame, four sliders slidably installed inside the corresponding slide rails, the transmission component is connected to the four locking blocks for transmission, and the four locking blocks can be driven to abut against the surfaces of the four slide rails by adjusting the handle.

[0006] Preferably, the transmission assembly includes a rotating block fixedly installed at one end of the handle, a plug rod rotatably installed on one side of the rotating block, a connecting strip fixedly installed at one end of the plug rod, a sleeve fitted on one end of the surface of the plug rod, one side of the sleeve fixedly connected to the movable frame, a pressure plate fixedly installed at the other end of the surface of the plug rod, and a return spring fitted in the middle of the surface of the plug rod, with both ends of the return spring fixedly connected to the pressure plate and the sleeve, respectively.

[0007] Preferably, push-pull rods are rotatably installed on both sides of the connecting strip, and support arms are rotatably installed on the ends of the two push-pull rods that are far apart from each other. The two ends of the two support arms that are far apart from each other are respectively fixedly connected to four locking blocks. Limit blocks are fixedly installed on the side of the two support arms that are close to the movable frame. Limit grooves are opened at the four corners of the side of the movable frame that is far away from the fixed frame. The four limit blocks are slidably installed inside the corresponding limit grooves.

[0008] Preferably, a locking rod is fixedly installed on the upper part of the rotating block, a limiting seat is provided on one side of the handle, one side of the limiting seat is fixedly connected to the movable frame, two stops are symmetrically arranged on the upper part of the limiting seat, and a pull ring is fixedly installed on the side of the two stops that are far apart from each other by a sliding rod. A sliding sleeve is fitted on one end of the surface of the two sliding rods, and one end of the sliding sleeve is fixedly connected to the movable frame. A telescopic spring is fitted on the other end of the surface of the two sliding rods, and both ends of the telescopic spring are fixedly connected to the stop and the sliding sleeve respectively.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator pushes the movable frame to the required position according to the width of the PCBA to be loaded. When the movable frame moves, it drives the four sliders to slide along the inside of the four slide rails, which increases the stability of the movable frame when it moves. After the movable frame is moved to the required position, the operator pulls the handle. When the handle is pulled, it drives the insert rod to slide along the inside of the insert sleeve through the rotating block, and at the same time, it squeezes the reset spring through the pressure plate. When the insert rod moves, it pushes the two push-pull rods to extend through the connecting strip. When the two push-pull rods extend, they push the four locking blocks to move through the two support arms. When the four locking blocks move, they all drive the limiting blocks to slide along the inside of the limiting groove, which increases the stability of the four locking blocks when they move. When the four locking blocks move, they drive the four anti-slip pads to press against the surface of the four slide rails, and the movable frame is fixed and limited by friction.

[0010] Then, the operator rotates the handle 90°, causing the handle to drive the locking rod through the rotating block to push the two stops in opposite directions to avoid them. When the two stops move in opposite directions, they drive the two sliding rods to slide back and forth along the inside of the two sliding sleeves, while simultaneously compressing the two telescopic springs. When the locking rod enters the interior of the limiting seat, the elastic force of the two telescopic springs will push the two stops to move towards each other and reset, thereby limiting the locking rod and locking it to prevent the handle from rotating and ensuring the stability of the movable frame positioning. Then, the operator places the PCBA into the placement slot in sequence. This allows the PCBA loading frame to quickly and easily adjust the placement width, has strong adaptability, and can be compatible with different sized boards, avoiding space waste or board loosening.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1 to 5 The present invention includes a base plate 1, with support rods 2 fixedly installed at the four corners of the top of the base plate 1. A top plate 3 is fixedly installed between the tops of the four support rods 2. A fixed frame 4 is fixedly installed on one side between the top plate 3 and the base plate 1. A movable frame 6 is provided in the middle between the top plate 3 and the base plate 1. Several placement slots 8 are provided on the side of the fixed frame 4 and the movable frame 6 that are close to each other. Four limiting blocks 24 are provided on the other side of the movable frame 6. Anti-slip pads 23 are fixedly installed on the inner walls of the limiting blocks 24. A handle 11 is provided in the middle of the other side of the movable frame 6. A transmission component is provided at one end of the handle 11. A protective plate 7 covering the transmission component is fixedly installed on the side of the movable frame 6 away from the fixed frame 4. Two slide rails 9 are fixedly installed on the side of the top plate 3 and the base plate 1 that are close to each other. Two sliders 10 are provided on the top and bottom of the movable frame 6. The four sliders 10 are slidably installed inside the corresponding slide rails 9. The transmission component is connected to four locking blocks 22. By adjusting the handle 11, the four locking blocks 22 can be driven to abut against the surfaces of the four slide rails 9.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator pushes the movable frame 6 to the required position according to the width of the PCBA to be loaded. When the movable frame 6 moves, it drives the four sliders 10 to slide along the inside of the four slide rails 9, which increases the stability of the movable frame 6 when it moves. After the movable frame 6 is moved to the required position, the operator pulls the handle 11. When the handle 11 is pulled, it drives the four anti-slip pads 23 to press against the surface of the four slide rails 9 through the transmission component, and the movable frame 6 is fixed and limited by friction.

[0022] Then, the operator rotates handle 11 90° to lock it, preventing handle 11 from rotating on its own and ensuring the stability of the positioning of the movable frame 6. Then, the operator places the PCBA into the placement slot 8 in sequence. This allows the PCBA loading frame to quickly and easily adjust the placement width, has strong adaptability, and can be compatible with different sized boards, avoiding space waste or board loosening.

[0023] The transmission assembly includes a rotating block 12 fixedly installed at one end of the handle 11. A plug rod 14 is rotatably installed on one side of the rotating block 12. A connecting strip 18 is fixedly installed at one end of the plug rod 14. A sleeve 15 is fitted onto one end of the surface of the plug rod 14. One side of the sleeve 15 is fixedly connected to the movable frame 6. A pressure plate 16 is fixedly installed at the other end of the surface of the plug rod 14. A return spring 17 is fitted onto the middle of the surface of the plug rod 14. The two ends of the return spring 17 are fixedly connected to the pressure plate 16 and the sleeve 15, respectively. Push-pull rods 19 are rotatably installed on both sides of the connecting strip 18. Support arms 21 are rotatably installed at the ends of the two push-pull rods 19 that are far apart from each other. The two ends of the two support arms 21 that are far apart from each other are fixedly connected to four locking blocks 22, respectively. Limiting blocks 24 are fixedly installed on the side of the two support arms 21 that are close to the movable frame 6. Limiting grooves 25 are opened at the four corners of the side of the movable frame 6 that are far away from the fixed frame 4. The four limiting blocks 24 are slidably installed inside the corresponding limiting grooves 25.

[0024] After moving the movable frame 6 to the desired position, the operator pulls the handle 11. When the handle 11 is pulled, the rotating block 12 drives the insertion rod 14 to slide along the inside of the insertion sleeve 15, and at the same time, the pressure plate 16 squeezes the return spring 17. When the insertion rod 14 moves, the connecting bar 18 pushes the two push-pull rods 19 to extend. When the two push-pull rods 19 extend, the two support arms 21 push the four locking blocks 22 to move. When the four locking blocks 22 move, they all drive the limiting block 24 to slide along the inside of the limiting groove 25, which increases the stability of the four locking blocks 22 when they move. When the four locking blocks 22 move, they drive the four anti-slip pads 23 to press against the surface of the four slide rails 9, and the friction force achieves the fixed limit of the movable frame 6.

[0025] A locking rod 13 is fixedly installed on the upper part of the rotating block 12. A limiting seat 20 is provided on one side of the handle 11. One side of the limiting seat 20 is fixedly connected to the movable frame 6. Two stops 26 are symmetrically arranged on the upper part of the limiting seat 20. Pull rings 29 are fixedly installed on the side of the two stops 26 that are far apart from each other through slide rods 27. Slide sleeves 28 are fitted on one end of the surface of the two slide rods 27. One end of the slide sleeves 28 is fixedly connected to the movable frame 6. Telescopic springs 5 ​​are fitted on the other end of the surface of the two slide rods 27. Both ends of the telescopic springs 5 ​​are fixedly connected to the stops 26 and the slide sleeves 28, respectively.

[0026] The operator rotates handle 11 by 90°, causing handle 11 to drive lever 13 via rotating block 12 to push two stops 26 to move backwards and avoid them. When the two stops 26 move backwards, they drive two slide rods 27 to slide backwards along the inside of two sliding sleeves 28, and at the same time, they compress two telescopic springs 5. When lever 13 enters the interior of limit seat 20, under the elastic force of the two telescopic springs 5, it will push the two stops 26 to move towards each other and reset, thereby limiting lever 13 and locking it, preventing handle 11 from rotating and ensuring the stability of positioning of movable frame 6.
