[0003] While automated PCBA integrated circuit boards offer numerous advantages in manufacturing and use, their installation flexibility is somewhat limited in practical applications. Traditional installation methods typically use bolts and other fasteners to secure the PCBA integrated circuit board to the chassis or frame to ensure the stability and reliability of the circuit board. However, this installation method suffers from the problem of difficult disassembly and assembly. Not only does it require specialized tools to tighten or loosen the bolts, but replacing or repairing the circuit board often necessitates a significant amount of time and effort for disassembly and reinstallation, limiting the flexibility of the PCBA integrated circuit board in terms of installation location. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a highly flexible automated PCBA integrated circuit board to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a highly flexible automated PCBA integrated circuit board, including a base and a circuit board body. A heat-conducting plate is embedded and fixedly installed on the top of the base. A plurality of linearly arrayed heat dissipation fins are fixedly connected to the bottom surface of the heat-conducting plate. The bottom surface of the circuit board body is in contact with the top surface of the heat-conducting plate. L-shaped positioning plates are slidably connected to both the front and rear sides of the circuit board body. Two symmetrically arranged clamping plates are fixedly connected to the bottom surface of each L-shaped positioning plate. The clamping plates are engaged with the base. Two symmetrically arranged pins are fixedly connected to the inner wall of each L-shaped positioning plate. The pins are slidably connected to the circuit board body. Sliding grooves are provided on both the left and right sides of the base. A partition plate is fixedly connected to the inner wall of the slide groove. Two symmetrically arranged slide plates are slidably connected to the inner wall of each slide groove. A movable plate is fixedly connected between the two left and right corresponding slide plates. The side of the two movable plates near the main body of the circuit board is respectively attached to the front and rear sides of the base. Several linear array pressure plates are fixedly connected to the top of each movable plate. The bottom surface of the pressure plate is attached to the top surface of the L-shaped positioning plate. A control rod is slidably connected to one side of the partition plate. A transmission plate is fixedly connected to one end of the control rod. Two symmetrically arranged springs are fixedly connected between the transmission plate and the base. Two symmetrically arranged locking pins are fixedly connected to the side of the transmission plate near the springs. The two locking pins pass through the base and are respectively engaged with the two slide plates.

[0007] Preferably, one side of the slide plate has a locking hole, and the two locking pins pass through the base and engage with the two slide plates respectively through the locking hole.

[0008] Preferably, in any of the above embodiments, the inner wall of the chute is fixedly connected with a plurality of linearly arrayed baffles, and the slide plate is slidably connected to the baffles.

[0009] Preferably, one side of the partition plate has a through hole, and the control rod is slidably connected to the partition plate through the through hole.

[0010] Preferably, in any of the above embodiments, heat dissipation grooves are provided through the front and rear sides of the base, and the two heat dissipation grooves correspond to the heat dissipation fins.

[0011] Preferably, the top surface of the circuit board body has a plurality of symmetrically arranged pin holes, and the plurality of pins are slidably connected to the circuit board body through the pin holes.

[0012] Preferably, the top surface of the base is fixedly connected with a number of symmetrically arranged slots, and the slots are engaged with the base by the slots.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. This device achieves initial positioning and installation of the circuit board body through the cooperation of an L-shaped positioning plate and a pin shaft. First, the pin hole of the circuit board body is aligned with the pin shaft and inserted, so that the circuit board body is initially positioned on the base. At the same time, the retaining plate at the bottom of the L-shaped positioning plate automatically engages and fixes with the retaining groove of the base. Then, the moving plate drives the pressure plate to press down, so that the pressure plate fits tightly against the top of the L-shaped positioning plate, completing the final fixation. For disassembly, simply push the control lever to drive the transmission plate to compress the spring, causing the locking pin to disengage from the locking hole of the sliding plate, thus releasing the pressure plate and easily removing the circuit board body. This design enables rapid assembly and disassembly of the circuit board, greatly improving maintenance efficiency, and is particularly suitable for automated production line applications that require frequent circuit board replacements.

[0014] 2. This device employs a multi-layer heat dissipation structure to ensure the stable operation of the circuit board. The heat generated by the circuit board is directly conducted to the heat-conducting plate through the bottom surface, and the heat-conducting plate evenly distributes the heat to multiple heat dissipation fins. The heat dissipation fins exchange heat with the outside air through heat dissipation slots on both sides of the base, and the dust filter effectively prevents dust from entering and affecting the heat dissipation effect. This heat dissipation system achieves rapid heat conduction and efficient heat dissipation, significantly improving the working stability and lifespan of integrated circuits, and is particularly suitable for the heat dissipation needs of high power density electronic devices.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following.

[0018] like Figures 1 to 8 As shown, a highly flexible automated PCBA integrated circuit board includes a base 1 and a circuit board body 2. A heat-conducting plate 3 is embedded and fixedly installed on the top of the base 1. Several linear array heat dissipation fins 4 are fixedly connected to the bottom surface of the heat-conducting plate 3. The bottom surface of the circuit board body 2 is in contact with the top surface of the heat-conducting plate 3. L-shaped positioning plates 5 are slidably connected to both the front and rear sides of the circuit board body 2. Two symmetrically arranged clamping plates 6 are fixedly connected to the bottom surface of each L-shaped positioning plate 5. Several clamping plates 6 are engaged with the base 1. Two symmetrically arranged pins 7 are fixedly connected to the inner wall of each L-shaped positioning plate 5. Several pins 7 are slidably connected to the circuit board body 2. Slide grooves 8 are opened on both the left and right sides of the base 1. A partition plate 9 is fixedly connected to the inner wall of each slide groove 8. The inner wall of the slide 8 is slidably connected to two symmetrically arranged slide plates 10. A movable plate 11 is fixedly connected between the two left and right corresponding slide plates 10. The two movable plates 11 are respectively attached to the front and rear sides of the base 1 on the side closest to the main body 2 of the circuit board. Several linear array pressure plates 12 are fixedly connected to the top of each movable plate 11. The bottom surface of the pressure plate 12 is attached to the top surface of the L-shaped positioning plate 5. A control rod 13 is slidably connected to one side of the partition plate 9. A transmission plate 14 is fixedly connected to one end of the control rod 13. Two symmetrically arranged springs 15 are fixedly connected between the transmission plate 14 and the base 1. Two symmetrically arranged locking pins 16 are fixedly connected to the side of the transmission plate 14 closest to the springs 15. The two locking pins 16 penetrate the base 1 and are respectively engaged with the two slide plates 10.

[0019] As an optional technical solution of this utility model, a locking hole 17 is provided through one side of the slide plate 10. Two locking pins 16 pass through the base 1 and are respectively engaged with the two slide plates 10 through the locking hole 17. The locking hole 17 and the locking pin 16 on the slide plate 10 realize the reliable fixation of the moving plate 11. This mechanical locking method ensures that the pressure plate 12 applies stable pressure to the L-shaped positioning plate 5, preventing the circuit board body 2 from loosening in a vibration environment. At the same time, the precise machining of the locking hole 17 ensures the smooth insertion and removal of the locking pin 16, so that the locking state can be quickly released during equipment maintenance, which greatly improves the maintainability of the equipment.

[0020] As an optional technical solution of this utility model, the inner wall of the slide groove 8 is fixedly connected with a number of linear array baffles 18, and the slide plate 10 is slidably connected to the baffles 18. The baffles 18 provided on the inner wall of the slide groove 8 provide precise sliding guidance for the slide plate 10. This linear array baffle design effectively prevents the slide plate 10 from deviating or getting stuck during movement, ensuring that the moving plate 11 can apply pressure smoothly. The baffles 18 also play a limiting role, preventing the slide plate 10 from moving excessively and causing damage to the mechanism, thereby improving the service life and reliability of the equipment.

[0021] As an optional technical solution of this utility model, a through hole 19 is provided on one side of the partition plate 9. The control rod 13 is slidably connected to the partition plate 9 through the through hole 19. The through hole 19 on the partition plate 9 provides a precise sliding channel for the control rod 13. This design ensures that the control rod 13 maintains linear movement during operation and will not deviate. The smooth inner wall of the through hole 19 reduces frictional resistance, making the insertion and removal of the locking pin 16 easier and less strenuous. At the same time, this structural design also facilitates the assembly and maintenance of the equipment.

[0022] As an optional technical solution of this utility model, heat dissipation slots 20 are provided through the front and rear sides of the base 1. The two heat dissipation slots 20 correspond to the heat dissipation fins 4. A dustproof net 21 is fixedly connected to the inner wall of each heat dissipation slot 20. The corresponding design of the heat dissipation slots 20 and heat dissipation fins 4 on the front and rear sides of the base 1 forms an efficient heat dissipation channel. The dustproof net 21 effectively blocks dust and foreign objects from entering while ensuring air circulation. This heat dissipation system can quickly dissipate the heat of the heat dissipation fins 4 to the external environment, prevent heat from accumulating inside the base 1, and significantly improve the heat dissipation efficiency and working stability of the circuit board.

[0023] As an optional technical solution of this utility model, the top surface of the circuit board body 2 is provided with a number of symmetrically arranged pin holes 22, and a number of pin shafts 7 are slidably connected to the circuit board body 2 through the pin holes 22. The sliding connection between the pin holes 22 on the top surface of the circuit board body 2 and the pin shafts 7 realizes the precise positioning of the circuit board. This design ensures that the circuit board body 2 can be accurately aligned during installation. The symmetrical arrangement of the pin holes 22 makes the force more balanced and prevents the circuit board from deforming due to uneven force. At the same time, this connection method also facilitates the quick disassembly and replacement of the circuit board.

[0024] As an optional technical solution of this utility model, the top surface of the base 1 is fixedly connected with a number of symmetrically arranged slots 23, and a number of locking plates 6 are engaged with the base 1 through the slots 23. The engaging design of the slots 23 and locking plates 6 on the top surface of the base 1 provides a reliable fixing method for the L-shaped positioning plate 5. This mechanical engaging structure is simple and reliable and can withstand greater vibration and impact. The symmetrical arrangement of the slots 23 ensures the installation stability of the L-shaped positioning plate 5. At the same time, this design also facilitates the rapid assembly and disassembly of the equipment and improves the maintenance efficiency of the equipment.

At the same time, the card plate 6 at the bottom of the L-shaped positioning plate 5 is automatically engaged and fixed with the card slot 23 of the base 1.

[0026] 2): The moving plate 11 drives the pressure plate 12 to press down, so that the pressure plate 12 fits tightly against the top of the L-shaped positioning plate 5, thus completing the final fixation.

[0027] 3): During disassembly, simply push the control lever 13 to drive the transmission plate 14 to compress the spring 15, causing the locking pin 16 to disengage from the locking hole 17 of the slide plate 10, thereby releasing the pressure plate 12 and easily removing the circuit board body 2.

[0028] In summary, this highly flexible automated PCBA integrated circuit board utilizes the L-shaped positioning plate 5 and the pin shaft 7 to achieve initial positioning and installation of the circuit board body 2. First, the pin hole 22 of the circuit board body 2 is aligned with the pin shaft 7 and inserted, initially positioning the circuit board body 2 on the base 1. Simultaneously, the retaining plate 6 at the bottom of the L-shaped positioning plate 5 automatically engages and secures with the retaining groove 23 of the base 1. Subsequently, the moving plate 11 drives the pressure plate 12 downwards, ensuring the pressure plate 12 fits tightly against the top of the L-shaped positioning plate 5, completing the final fixation. For disassembly, simply push the control lever 13 to compress the transmission plate 14 and spring 15, causing the locking pin 16 to disengage from the locking hole 17 of the sliding plate 10, releasing the pressure plate 12 and easily removing the circuit board body 2. This design enables rapid assembly and disassembly of circuit boards, significantly improving maintenance efficiency. It is particularly suitable for automated production lines requiring frequent circuit board replacements. The device employs a multi-layer heat dissipation structure to ensure stable operation of the circuit board body 2. The heat generated by the circuit board body 2 is directly conducted to the heat-conducting plate 3 through its bottom surface. The heat-conducting plate 3 evenly distributes the heat to multiple heat dissipation fins 4. The heat dissipation fins 4 exchange heat with the external air through heat dissipation slots 20 on both sides of the base 1. The dustproof mesh 21 effectively prevents dust from entering and affecting the heat dissipation effect. This heat dissipation system achieves rapid heat conduction and efficient heat dissipation, significantly improving the operational stability and lifespan of integrated circuits, making it particularly suitable for the heat dissipation needs of high-power-density electronic devices.
