Description

Technical Field

[0001] This utility model relates to the field of transfer tools, and in particular to a turnover cart for electrical circuit boards. Background Technology

[0002] In the production, testing, and assembly of electrical circuit boards, these boards can be transported using trolleys, facilitating their orderly storage and convenient transfer. These trolleys typically consist of a main frame with multiple layers of storage structures for the circuit boards, such as pull-out trays, shelves, or slots. Workers can place the circuit boards one by one into these structures, maintaining their relatively orderly arrangement during transport and preventing direct stacking and compression. This completes the transfer of electrical circuit boards from one operational stage to another, ensuring the continuity of the production process.

[0003] However, existing electronic circuit board trolleys lack sufficient anti-static adjustment and storage capabilities when transporting electronic circuit boards, making it difficult to meet the transportation needs of high-precision electronic circuit boards. During transportation, it may be difficult to effectively eliminate static electricity generated by friction between the circuit board and the storage structure, as well as airflow. Static electricity accumulation can not only interfere with the performance of electronic components on the circuit board, but in severe cases, it can even damage the components and the circuit board, significantly affecting the safety and reliability of the transportation process. Furthermore, their vibration protection and anti-static protection capabilities are insufficient, and their ability to adjust the height of the storage space and the positioning of the circuit board is inadequate, easily leading to circuit board swaying within the storage structure, further impacting the safety and reliability of the transportation process. Therefore, we propose an electronic circuit board trolley to solve these problems. Utility Model Content

The anti-static placement boxes 4 are equipped with magnetic snap-fit ​​anti-vibration plug-in magnetic blocks 6 located on the top of the placement support frames 2 on both sides. The top of the anti-static placement boxes 4 is fitted with an abutment cover plate 7. An anti-vibration protection arm 8 is inserted into the middle of the abutment cover plate 7.

[0029] The beneficial effects that this plan aims to achieve are:

[0030] By providing support columns 3 at the top four corners of the main body 1 of the turnover cart, it is easy to place the support frame 2 for lifting and adjusting on the support columns 3. The support frame 2 can support and store the anti-static storage box 4. Both sides of the anti-static storage box 4 are provided with shockproof plug-in magnetic blocks 6, which can be magnetically attached to the top sides of the support frame 2. The magnetic positioning and locking effect is good, making it easy to pick up and put down the anti-static storage box 4 and install it stably.

The top of the antistatic storage box 4 is equipped with a closing ring 402, which facilitates the installation and sealing of the cover plate 7, resulting in a good installation and closing effect.

[0042] Furthermore, a support and protection ring 701 is provided in the middle of the abutment cover plate 7, and the vibration protection arm 8 is threaded to the middle of the support and protection ring 701. The two ends of the vibration protection arm 8 are located on the upper and lower sides of the abutment cover plate 7, respectively.

[0043] Specifically, a support and protection ring 701 is provided in the middle of the abutment cover plate 7, so that the support and protection ring 701 can support and bear the vibration protection arm 8. The vibration protection arm 8 is easy to adjust by rotating and lifting with its threads, and is highly durable and easy to use.

[0044] Furthermore, the bottom of the anti-vibration protection arm 8 is fitted with a circuit board abutment pad 801, and the top of the anti-vibration protection arm 8 is provided with a manual adjustment handle 802.

[0045] Specifically, the bottom of the anti-vibration protection arm 8 is fitted with a circuit board abutment pad 801. The circuit board abutment pad 801 acts as an abutment pad for the circuit board, providing good flexible compression protection and playing a role in protection and anti-static. It compresses and positions the circuit board, making it less likely to shake and fall off during turnover. The positioning is stable, and the manual adjustment handle 802 can be held and rotated by hand, making manual operation convenient and suitable for use.
