Description

Technical Field

[0001] This utility model relates to the field of PCBA circuit board transportation technology, and more specifically to a modular PCBA circuit board transportation device that can be quickly assembled. Background Technology

[0002] PCBA, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and provides the connection for electronic component circuits. PCBA is made using electronic printing technology, hence the name "printed" circuit board. As a core component of electronic products, the efficiency and safety of its production and transportation process directly affect the overall manufacturing cost and product quality. Traditionally, PCBA transportation uses fixed-size anti-static turnover carts, pallets, or customized carriers.

[0003] When transporting circuit boards on bumpy roads, the printed circuit boards inside the traditional vehicle may collide with each other, potentially causing damage. Existing vehicles cannot effectively absorb shocks or adjust the buffer stroke according to the number of circuit boards being transported. Furthermore, the circuit boards may rust and corrode in humid environments during transport. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modular PCBA circuit board transportation device that can be quickly assembled, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a modular PCBA circuit board transportation device that can be quickly assembled, including a fixed base plate, a buffer mechanism fixedly connected to the top of the fixed base plate, a transportation box fixedly connected to the top of the buffer mechanism, a sealing cover movably connected to the top of the transportation box, and an air blowing mechanism fixedly connected to the middle of the top of the fixed base plate; the buffer mechanism includes a connecting plate fixedly connected to the bottom end of the fixed base plate, a limit rod fixedly connected to the bottom end of the connecting plate, a limit cylinder movably connected to the bottom end of the side of the limit rod, a support plate fixedly connected to the bottom end of the limit cylinder, and a buffer spring provided on the side of the limit rod and the limit cylinder, the buffer spring being located between the connecting plate and the limit cylinder.

[0006] Furthermore, the bottom of the transport box is provided with a gas hole, which is located directly above the air blowing mechanism. Both sides of the top of the fixed base plate are provided with a buffer mechanism, which supports both sides of the bottom of the fixed base plate.

[0007] Furthermore, connecting rods are fixedly connected to both sides of the bottom end of the connecting plate, a limiting plate is fixedly connected to the bottom end of the connecting rods, a moving block is movably connected to the side of the limiting plate, and a support seat is fixedly connected to both ends of the support plate. The top end of the support seat is provided with an avoidance groove that matches the moving block.

[0008] Furthermore, the top of the movable block is provided with a limiting groove for the limiting plate to move, and the bottom of the movable block is provided with a threaded hole. A handwheel is threadedly connected to the threaded hole of the movable block, and a threaded rod is fixedly connected to the bottom of the handwheel.

[0009] Furthermore, the side of the threaded rod is movably connected to the interior of the support base, and sliders are fixedly connected to both sides of the top of the support base. Slide grooves adapted to the sliders are opened on both sides of the movable block.

[0010] Furthermore, the air blowing mechanism includes a support leg for support and fixation, a support frame is fixedly connected to the top of the support leg, a motor is fixedly connected to the bottom of the support frame, a rotating shaft is fixedly connected to the top of the motor, and a blade assembly is fixedly connected to the top of the rotating shaft.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model includes a connecting plate, a buffer spring, a moving block, and a handwheel. When the circuit board is transported in a transport box and experiences bumps and vibrations, the transport box moves the connecting plate upwards. When the connecting plate moves downwards, it compresses the buffer spring, thus providing cushioning. When transporting different numbers of circuit boards, rotating the threaded rod causes the moving block to move the connecting plate up and down. After the connecting plate moves up and down, the travel and preload of the buffer spring are adjusted to adapt to different numbers of circuit boards.

[0013] 2. This utility model is equipped with a motor, a rotating shaft, and a blade assembly. When the circuit board is transported in a transport box, the motor starts and drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the blade assembly to rotate. When the blade assembly rotates, it blows the gas upward. The upward-blown gas enters the fixed substrate through the gas hole, thereby ventilating the interior of the fixed substrate and preventing the fixed substrate from becoming damp and causing rust and corrosion.

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figure 1 This utility model provides a modular PCBA circuit board transportation device that can be quickly assembled, including a fixed base plate 1, a buffer mechanism 2 fixedly connected to the top of the fixed base plate 1, a transportation box 3 fixedly connected to the top of the buffer mechanism 2, a sealing cover 4 movably connected to the top of the transportation box 3, an air blowing mechanism 5 fixedly connected to the middle of the top of the fixed base plate 1, an air hole 6 opened at the bottom of the transportation box 3, the air hole 6 being located directly above the air blowing mechanism 5, and buffer mechanisms 2 provided on both sides of the top of the fixed base plate 1, the buffer mechanisms 2 supporting the two sides of the bottom of the fixed base plate 1.

[0022] In this embodiment, the gas hole 6 is located directly above the blowing mechanism 5. At this time, the gas hole 6 allows the air blown out by the blowing mechanism 5 to pass through, ensuring the ventilation effect. The buffer mechanism 2 supports both sides of the bottom end of the fixed substrate 1, ensuring the stability of the buffer mechanism 2 supporting the fixed substrate 1.

[0023] Reference Figure 2 , Figure 3 as well as Figure 4The buffer mechanism 2 includes a connecting plate 201 fixedly connected to the bottom end of the fixed base plate 1. A limiting rod 202 is fixedly connected to the bottom end of the connecting plate 201. A limiting cylinder 203 is movably connected to the bottom end of the side of the limiting rod 202. A support plate 205 is fixedly connected to the bottom end of the limiting cylinder 203. A buffer spring 204 is provided on the side of the limiting rod 202 and the limiting cylinder 203. The buffer spring 204 is located between the connecting plate 201 and the limiting cylinder 203. Connecting rods 206 are fixedly connected to both sides of the bottom end of the connecting plate 201. A limiting plate 207 is fixedly connected to the bottom end of the connecting rods 206. A moving block 2 is movably connected to the side of the limiting plate 207. 08. Support bases 209 are fixedly connected to both ends of support plate 205. The top of support base 209 is provided with a clearance groove that matches the movable block 208. The top of movable block 208 is provided with a limiting groove that allows the limiting plate 207 to move. The bottom of movable block 208 is provided with a threaded hole. A handwheel 211 is threadedly connected to the threaded hole of movable block 208. A threaded rod 210 is fixedly connected to the bottom of handwheel 211. The side of threaded rod 210 is movably connected to the inside of support base 209. Slider 212 is fixedly connected to both sides of the top of support base 209. Slider grooves that match slider 212 are provided on both sides of movable block 208.

[0024] In this embodiment, when the transport box 3 moves up and down, it drives the connecting plate 201 to move up and down. When the connecting plate 201 moves up and down, it compresses the buffer spring 204 to buffer the movement. When the threaded rod 210 rotates, it drives the handwheel 211 to rotate. The rotation of the handwheel 211 causes the moving block 208 to move up and down. When the moving block 208 moves upward, it drives the connecting plate 201 to move up and down through the limiting plate 207 and the connecting rod 206. When the connecting plate 201 moves up and down, it adjusts the stroke of the buffer spring 204, which can be used in different environments. The moving block 208 has grooves on both sides that are adapted to the slider 212, so that the moving block 208 will not derail when it is adjusted and moves up and down.

[0025] Reference Figure 2 and Figure 5 The blowing mechanism 5 includes a support leg 501 for support and fixation. A support frame 502 is fixedly connected to the top of the support leg 501.

A blade assembly 505 is fixedly connected to the top of the rotating shaft 504.

[0026] In this embodiment, the motor 503 starts and drives the blade assembly 505 to rotate through the rotating shaft 504. When the blade assembly 505 rotates, it blows the gas upward. The upward-blown gas enters the fixed base plate 1 through the gas hole 6. At this time, the interior of the fixed base plate 1 is ventilated to avoid rust and corrosion.

[0027] The working principle of this utility model is as follows: When transporting circuit boards, the circuit boards are placed in the transport box 3 and the sealing cover 4 is closed. According to the number of circuit boards being transported and the road conditions, the threaded rod 210 is rotated. When the threaded rod 210 rotates, it drives the handwheel 211 to rotate. When the handwheel 211 rotates, it causes the moving block 208 to move up and down. When the moving block 208 moves upward, it drives the connecting plate 201 to move up and down through the limiting plate 207 and the connecting rod 206. When the connecting plate 201 moves up and down, the stroke of the buffer spring 204 is adjusted. After adjustment, the circuit board is transported.

[0028] When encountering uneven road surfaces, the transport box 3 will bounce up and down. When the transport box 3 moves up and down, it drives the connecting plate 201 to move up and down. When the connecting plate 201 moves up and down, it compresses the buffer spring 204 to buffer the movement. When the connecting plate 201 moves up and down, it causes the limiting plate 207 to move within the moving block 208, ensuring the stability of the connecting plate 201 during movement.

[0029] When the environment during transportation is relatively humid, the motor 503 starts and drives the rotating shaft 504 to rotate. When the rotating shaft 504 rotates, it drives the blade assembly 505 to rotate. When the blade assembly 505 rotates, it blows the gas upward. The upward-blown gas enters the fixed base plate 1 through the gas hole 6. At this time, the interior of the fixed base plate 1 is ventilated to avoid rust and corrosion.

[0030] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
